fir I. r~rm.r~_ The National Convocation on Middle Grades Mathematics was followed by three separate Action Conferences, funded by support from the Department of Education and additional support from the American Educational Research Association. The following three papers synthesize the activities and discussion that occurred during the three conferences. ACTION CONFERENCE ON THE NATURE AND IMPACT OF ALGEBRA AT THE MIDDLE GRADES Organized by Hyman Bass, Columbia University This action conference focused on providing school based decision makers with an unclerstancling of the importance of bringing algebra into the micic3le gracles and the issues involved in making this happen. ACTION CONFERENCE ON RESEARCH IN THE TEACHING AND LEARNING OF MATHEMATICS IN THE MIDDLE GRADES Organized by Sandra Wilcox, Department of Teacher Education, Michigan State University The conference was clesignec3 around the question: What are the characteristics of research that would be helpful and informative for teaching mathematics in the micic3le gracles? ACTION CONFERENCE ON THE PROFESSIONAL DEVELOPMENT OF TEACHERS OF MATHEMATICS IN THE MIDDLE GRADES Organized by Deborah Ball, University of Michigan. The participants worked through a frame for considering the design and practice of teacher development at the micic3le gracles, examining the ideas that drive professional development in the light of what is known and unknown about teacher learning.

r.~.r~ Synthesis by Bradford Findell Program Off cer, National Research Council The Action Conference on the Nature and Teaching of Algebra in the Middle Grades brought together mathematicians, mathematics educa- tors, middle school teachers, math- ematics supervisors, curriculum developers, and others to discuss the role of algebra in the middle grades. The conference was provoked in part by recent events and policy decisions that have focused attention on algebra in the middle grades. Perhaps most prominent among these events was the release in 1997 of results in the Third International Mathematics anti Science Stu(ly MESS, which indicated, among other things, that the U.S. curriculum at eighth grade is about one year behind many other countries, and that U.S. eighth graders perform, as a group, below the international average in mathematics achievement. In the policy arena, several states recently mandated that algebra be a required course for high school gradua tion, and the pressure has expanded into the middle grades as well. In the U.S. Department of E(lucation's White Paper, Mathematics Equals Opportunity, Secretary Riley recommends, on the basis of a strong correlation with college attendance, that students take algebra or courses covering algebraic concepts by the en(1 of eighth gra(le. Despite the growing public attention to algebra in the middle grades, there has been little discussion (and perhaps little public acknowle(lgment) of the fact that there are more than a few possibili- ties for what algebra in the mi(l(lle gra(les might look like. Thus, the agenda for the Action Conference was (lesigne(1 to bring some of these possi- bilities to light through presentations on various views of algebra anti on re- search in the teaching and learning of algebra, together with practical experi- ences of teachers anti (1istricts who have been implementing some version of algebra in the middle grades. Discus

sion was framed by six questions (See Figure 1) that were presented by the Action Conference Organizer, Hyman Bass, a mathematician from Columbia University and Chair of the National Research Council's Mathematical Sciences Education Board. VIEWS OF ALGEBRA The first presenter was km Fey, a curriculum developer and mathematics education researcher from the Univer- sity of Maryland. He began the after- noon by reminding the participants that a big factor in the debate about the role of algebra is the social and political context. Algebra serves as a gateway to post-secondary study and to scientific and technical careers. And if algebra is good in ninth grade, then it is better in eighth grade, and some think even better in seventh. But there has been little attention to what the content of algebra is or may be. In the conventional view, algebra is primarily about calculation with sym- bols Bob Davis called it a dance of symbols. And algebra is used to solve word problems. But students are not very goo(1 at the wor(1 problems that we teach them, never mind problems that they haven't seen before. The increase(1 availability of calcula- tors and computers provides new ACTION CONFERENCE demands and opportunities for the teaching and learning of algebra. We may concentrate on the design and use of algorithms, on data modeling and predictions, or on analyzing anti project- ing trends. Spreadsheets anti other computing tools allow us to approach such ideas graphically, numerically, anti symbolically. Fey acknowledged that there is a fair amount of debate about what algebra is, but suggeste(1 the question might not be productive. Instead, he suggested that what we want from algebra are some concepts and techniques for reasoning about quantitative conditions and rela- tionships. There are four major aspects of such reasoning: representation, calculation, justification, anti application. Development of student understanding and skill in these areas can begin in the mi(l(lle gra(les. With such an approach, he notes, it will not be sufficient to take high school algebra and move it into the middle grades. Representation is about expressing complex relationships in efficient, condensed, symbolic form. Tradition- ally, the typical algebra question has been ' What is x?" But representations such as data tables, graphs, symbolic rules, and written expressions may be used to record and describe numerical patterns, formulas, patterns that change over time, and cause and effect relation- ships.

Figure ~ . Framing Questions SOME IMPORTANT QUESTIONS Attention to subject matter ~ attention to students In teaching algebra in the middle Oracles, what are the tensions between attention to serious ancl challenging mathematical content, on the one hancl, ancl, on the other hancl, sensitivity to clevelop- mental, social, ancl equity issues pertinent to adolescent chilclren? Algebra as the language of mathematics 2. If one thinks of algebra as the language of mathematics, then does the learning of algebra entail some of the same challenges encountered in the learning of reacling, ancl therefore call for a more cleliber- ate ancl focused attention to the task of teaching this formalization of mathematical expression ancl communication? Real world contexts ~ generalization and abstraction 3. Many have argued that in order to motivate student learning of mathematics, it should be presented concretely in terms of real life problems ancl situations. This has been interpreted by some to require that all mathematics learning be embeclclecl in complex empirical investigations ancl measurements. Is this really warrantecl, both in terms of the presumptions about student motivation, ancl as effective peclagogy? Does this shortchange the equally important mathematical processes of generalization ancl abstraction, i.e., the distillation or clecontextualization of mathematical ideas from multiple contexts? Mathematics curriculum: covering mathematics ~ uncovering mathematics A. TIMMS characterizes the U.S. curriculum in mathematics as a mile wide ancl an inch creep. One manifestation of this is the pressure on teachers to race through an overloaded curriculum in both standard ancl accelerated tracks-with little time for student reflection ancl inquiry with new icleas, a practice that flies in the face of what constructivist ideas tell us about the nature of learning. Is this true? Ancl, if so, what can be clone to change this conclition? Situating algebra in the mathematics curriculum? 5. How should algebra be situated in the curriculum? As a traditional focused algebra course, or integrated with other subject areas, such as geometry? As a strand across many Oracles? Mathematical curriculum: materials, design, selection criteria, . . . 6. What are the characteristics of currently available curriculum materials in terms of topic coverage, pedagogical approaches, use of technology, support ancl guidance for teachers, etc. What kinds of tradeoffs must be made in the adoption of one over another of these curricula? How can one measure the impact of curricular choices on issues of equity, teacher preparation, community understanding, program assessment, ancl articulation with elementary ancl high school programs? THE NATURE AND IMPACT OF ALGEBRA

Traditional approaches to algebra have focused on symbolic calculation, but calculation can be used to con- struct tables anti graphs of relation- ships, to solve equations, and to de- scribe rates of change and optimal values; major ideas in calculus that are often disregarded by calculus students who rely only on symbolic calculation. Calculation can aid in the construction of equivalent representations for quantitative relationships. The reason the representations are equivalent is that they both make sense for model- ing the same situation. In algebra, justification, reasoning, and proof are often considered in conjunction with the properties of the number system. But the properties of the number system are the way they are because the properties make sense. It is not the case that 2 + 3 = 3 + 2 because addition is commutative. Rather, addi- tion is commutative because verification that they both equal 5 can be general- ized to all numbers. Finally, applications can be pervasive from start to finish, providing frequent opportunities to move back and forth between abstraction and the real worI(l. Fey closed by pointing out that these curricular goals should be implemente with consideration of the ways students learn. He suggested that the way students encounter these i(leas must be changed from the "demonstrate, imitate, ACTION CONFERENCE and practice" style that has dominated algebra instruction. Al Cuoco, Director of the Center for Mathematics Education at EDC, pre- sented a view of algebra that was closer to a traditional view, in that symbol manipulation was more prominent anti the problems were more often from the world of mathematics. The emphasis was not on the manipulation, however, but rather on the ways of thinking that emerge from consideration of the historical (levelopment of the subject. Many of his points were illustrated by engaging mathematical problems. Cuoco prefaced his presentation with an acknowledgment that the points made by Fey were important, and then offered a list of possible answers to the question, ' What is algebra?" · Algebra is an area of mathematical research. · Algebra is the language of mathematics. . Algebra is a collection of skills. · Algebra is generalize(1 arithmetic. · Algebra is about "structure." · Algebra is about functions. · Algebra is about graphs. · Algebra is about mo(leling. · Algebra is a tool. Historically, algebra grew out of a long program of mathematical research that looked for ways to solve equations-ways that (li(ln't (lepen(1 upon the particulars of

the equations. Sometimes the methods for solving these equations worked in situations that had nothing to do with the originalsituation. People started thinking about properties of operations. Algebraic thinking involves reasoning about calculations. When is the aver- age of two averages the average of the whole lot? What is the sum, ~ + 2 + 4 + ~ + ... + 28? Which numbers can be written as sums of a sequence of consecutive whole numbers? In Euclid- ean division, why do the remainders have to keep getting smaller? Algebra involves reasoning about operations. Consider the following two problems: 1. Mary drives from Boston to Washington, a trip of 500 miles. If she travels at an average of 60 MPH on the way clown and 50 MPH on the way back, how many hours floes her trip take? 2. Mary drives from Boston to Washington, and she travels at an average of 60 MPH on the way clown and 50 MPH on the way back. If the total trip takes 18 1/3 hours, how far is Boston from Washington? The first problem can be solved by a sequence of direct computations. The second requires reasoning about opera- tions. Students can solve it using a "function machine" computer program that allows reasoning about operations. Triangular numbers have the recur- sion formula, a (n) = a (n - 1) + n. While THE NATURE AND IMPACT OF ALGEBRA investigating these numbers, one student saw that a (n) = n2 - a (n - 1) . This is surprising enough. Cuoco wants people to see that it is useful: Add the two formulas to get the closed form. Units digit arithmetic provides some opportunities for reasoning about calculations. What is the units digit of 24~3485 _ 75~332? Through questions like this, students can very quickly begin to reason about the system of arithmetic module ten. Some have argued that skins in symbol manipulation are less important today, but symbol manipulation is not just a skill. Knowledge is not a copy of reality. To know an object, to know an event, is not simply to look at it and make a mental copy or image of it. To know an object is to act on it. To know is to mollify, to transform the object, and to unclerstanc3 the process of this transformation, and as a consequence to unclerstanc3 the way an object is constructed. An operation is thus the essence of knowledge; it is an interiorizec3 action, which mollifies the object of knowledge. Cognitive development in children: Development and learning (Piaget, 1964) Symbol manipulation can also support mathematical thinking. An(1 many important mathematical ideas, such as geometric series, the binomial theorem, and the number theory behind Pythagorean triples, require rather sophisticated symbol manipulation.

During the question/answer period, both Cuoco and Fey agreed on the importance of algorithmic thinking an reasoning about relationships. Fey elaborated that the contexts provide a series of hooks, but it is important to go beyond the individual contexts to find the commonalities among the representations of various contexts. Hyman Bass sug- geste(1 that Fey's an(1 Cuoco's approaches are not in opposition, but emphasize two different aspects of the same thing. RESEARCH ON THE TEACHING AND LEARNING OF ALGEBRA Grit Zaslavsky, a mathematics educa- tion researcher from Israel, began her presentation by noting that in Israel there is no debate about whether to teach algebra. Because complete coverage of the research was not pos- sible, she decided to share an example of her own mathematical learning, which developed into a collaborative study of her graduate student, Hagit Sela, and her colleague, Uri Leron. Through this example she addressed research issues associated with teach- ing and learning algebra. She asked participants first to sketch the graph off = x on axes without scales, and then to sketch the graph of fix) = x on axes where the scales were different. For each case, she posed the following questions: 1. What is the slope of the line you sketched? How clic3 you determine it? 2. Does the line that you sketched clivicle the angle between the two axes into two congruent angles? How c30 you know? 3. Can you calculate tan fad, for the angle a between the line you sketched and the x-axis? If you were able to, how clic3 you calculate it? If not, why not? 4. Describe your considerations, reactions, dilemmas and other thoughts. Typical graphs are shown in Figure 2. For the first graph, most participants Figure 2. Typical graphs ACTION CONFERENCE -2 -3 3 2 y 1- l n ~3 -2 -1 ~ 1 ~ -1 Ad/ 1 Z x 6 Y4 --- - 1 ha - . 2 4

assumed that the scales were the same. Zaslavsky pointed out that most people think offal) = x as bisecting the right angle of the coordinate system. None of the four questions were problematic for the first graph. For the second graph, however, there was disagreement, as some participants focused on the scales of the axes and others focused on the angle visually made by the line in the first quadrant. Zaslavsky pointed out that with the advent of graphing technologies and the possibilities for scale change, there was a sense that everything was invariant under scale changes. But she thought that there were some things that were varying the angle in particular. This example raised many questions: What is the slope of a linear function? What is the relation between the slope and angle? Is the slope a characteristic of a Linear) function that is independent of its representation? Or is it a charac- teristic of its graphical representation? (Similar questions may be asked about derivative.) Does it make sense to talk about a function without reference to its representation? As part of a research project, Zaslavsky and her colleagues were investigating approaches to this set of tasks in various populations. Students, mathematics teachers, mathematics educators, and mathematicians all shared a sense of confusion and to THE NATURE AND IMPACT OF ALGEBRA some extent, inconsistency or disequi- librium. All felt a need to re-think, re- define, or re-construct meaning for what they hall thought of as fun(lamen- tal and rather elementary concepts: slope, scale, anti angle. In their research (as in the Action Conference) there were several qualita- tively different approaches to tackling the problem. Individual people brought their own perspectives. For some, slope is a geometric concept. When the scale is 1:3, the line does not bisect the angle. For others, slope is an analytic concept, and the "fact" that the line bisects the angle is a clear result of the analytic calculation. Still others questione(1 the meaning of y = x if the units of x are ifferent from the units of y. What (toes all this have to (lo with learning algebra in the middle grades? Learning is about constructing mean- ing. This meaning can change over time, across learners (even experts) and across contexts. The teacher shoul provide a rich context for building different perspectives and meanings. In algebra, even the notion of variable has several meanings: unknown, vary- ing, generalization, etc. Meaningful learning takes place when the learner (leals with a "real problem" in the sense that the problem is real to him or her. Research supports a contextual ap- proach in which students engage with problems to which they can relate.

The issue of representations is inher- ent to the learning of algebra. Students need to build meaning for graphical representations (which although visual are very often symbolic), and the connections between different forms of representation. Students need opportu- nities for reasoning from within repre- sentations and for translating among representations. And instruction should relate to and build on children's own invented representations. Finally, in mathematical learning, examples play a critical role. In study- ing functions, for instance, the examples that children see can profoundly innu- ence their concept image of function. Many students believe, for example, that functions are supposed to be continuous, that there can be no jumps, and that there has to be a rule. There are different levels and ways of knowing. Learning algebra in the middle grades is just the beginning. The hope is that in high school these mathematical concepts and ideas will continue to be revisited and rethought. IMPLEMENTATION The morning of the second day was devoted to presentations of various implementations of algebra in the middle grades. Blanche Brownley, Secondary Mathematics Specialist from ACTION CONFERENCE the District of Columbia Public Schools, served as moderator for presentations about the Connected Mathematics Project (CMP), University of Chicago School Mathematics Project (UCSMP), Mathematics in Context, and Saxon Mathematics. The afternoon begin with a panel discussion of more general issues of implementation and closed with a discussion of the need for re- search and recommendations on the role of algebra in the middle grades. CONNECTED MATHEMATICS PROJECT Yvonne Grant, from Traverse City, Michigan, initially participated in the Connected Mathematics Project as a field tester and received professional development through her involvement. Now she works as a teacher-coach for CMP. Traverse City's move to Con- nected Mathematics was prompted in part by lack of success with the previ- ous program. The CMP program was designed and developed from the principle that all students should be able to reason and communicate proficiently in mathematics. The materials focus on understanding. The units are built upon big mathematical ideas and are organized as integrated strands of mathematics Now after completing the CMP

program in gra(le eight, about half of the Traverse City students go into UCSMP Algebra, and about half go into UCSMP Geometry. The placement decision is made by students and parents because the high school often did not follow the middle school teach- ers' recommendations. A central component of Traverse City's implementation effort is profes- sional development for the teachers, which begins with an orientation in the summer. During the academic year, each teacher receives a half-day of professional development before begin- ning each CMP unit. Grant suggested that professional development has to evolve as teachers evolve, and described four phases in a teacher's implementa- tion of a new program such as CMP: · How to survive, Build a more comprehensive under- standing of content, Focus on instruction, and · Widen the view to connect with other units, other grades. Because there are teachers who are at different places on this continuum, designing school-w~de professional development activities is a challenge. The teachers in Traverse City enjoy additional support through the estab- lishment and growth of a professional community, supported through coach THE NATURE AND IMPACT OF ALGEBRA ing and common preparation times. The teachers also benefit from adminis- trative acceptance and support, and because colleagues and the board of education are well-informed about the program. Because some parents are concerned about whether students are learning their basic facts, and others are con- vinced that their children should be separated from the mainstream, the teachers have had to learn about how to talk to parents. It has become easier to talk to parents now that Traverse City Schools have shown some success on the Michigan Educational Assessment Program (MEAP). UNIVERSITY OF CHICAGO SCHOOL MATHEMATICS PROJECT Bonnie BuehIer discussed the use of the University of Chicago School Math- ematics Project materials at Springman Middle School in Glenview, Illinois, a suburb of Chicago. The UCSMP sec- on(lary program inclu(les six year-Ion" courses, beginning in gra(le 6 or 7 with Transition Mathematics, which is followed byAIgebra, and then Geometry. The program emphasizes reading, problem-solving, everyday applications, anti use of calculators, computers, anti other technology. The UCSMP ap- proach is called SPURs: Skills, Pro

cesses, Uses, and Representations. In Glenview, the philosophy is that all students benefit from rigorous math- ematics; they shouldn't have to wait until high school. So most students take Transition Mathematics in grade 7 and Algebra in eighth gra(le, though the algebra course is broader than the name implies, including a lot of geometry and what is usually called pre-aIgebra. About 25% of the eighth graders take Geometry, with an equal number of girls in this accelerated track. The emphasis on problem solving and cooperative learning seems to have helped gender equity. BuehIer said that her school provides graphing calculators, teacher materials, and a budget for outside resources, and pointed out that there have been huge achievement gains in Chicago schools using UCSMP, even in schools that have more limited resources. She suggested that teacher expectations are more important than resources. BuehIer emphasized that there was extensive staff-development during initial implementation of the UCSMP program. Now, new staff attend UCSMP conferences, and veteran teachers support new faculty. BuehIer noted that teachers in Texas recently aban(lone(1 UCSMP because they (li(ln't receive the support they nee(le(l. Sup- port is the responsibility of the user, not of the curriculum (leveloper, she ACTION CONFERENCE thought, although the materials ought to provide guidance on the need for professional development. For information about the effective- ness of their program, BuehIer men- tione(1 that on the Comprehensive Test of Basic Skills (CTBS), the skills scores have stayed the same and the concep tual scores have skyrocketed since the implementation ofUCSMP. More recently, the teachers have focused on skills for a few (lays before the test, anti skill scores have gone up as well. As further evidence of effectiveness, BuehIer (liscusse(1 Glenview schools' participation in the Third International Mathematics anti Science Stu(ly as part of the First in the World Consortium, a group of school (listricts in Suburban Chicago. When the Consortium is compared as a country with the other participating countries, only Singapore significantly outperformed the Consor- tium in mathematics, anti no country significantly outperformed the Consor · · ~ thrum In science. MATHEMATICS IN CONTEXT Susan Loftier, from Weimar Hills School, Weimar, California, spoke about Mathematics in Context, a comprehen- sive middle-school mathematics curricu- lum for grades 5 through 8, developed with support from the National Science

Foundation. Connections are a key feature of the program: connections among topics, connections to other disciplines, and connections between mathematics and meaningful problems in the real world. Mathematics in Context introduces concepts within realistic contexts that support math- ematical abstraction, with tasks and questions designed to stimulate math- ematical thinking and to promote discussion among students. With more than 10 years of experi- ence in efforts to improve their math- ematics programs, Loftier was al- ready familiar with some of the ideas behind Mathematics in Context and with the idea that all students can achieve higher standards. After remov- ing selection criteria for eighth grade algebra, for example, her district found that the two most important criteria for success were persistence and doing homework. Nonetheless, she was concerned when she first noticed that Mathematics in Context included linear · ~ ~. · ~ programming en cl linear regression in the eighth grade curriculum. At first, she didn't believe that students could do it, but she later changed her mind when she saw how the concepts were devel- oped beginning in the fifth grade. Loftier also emphasized the need for support anti professional (levelop- ment. Teachers meet once a month from 4 p.m. to 7 p.m. and are paid. THE NATURE AND IMPACT OF ALGEBRA Once a month, teachers get a release day as a team. Teachers need to be provi(le(1 with good research to support what they are doing. The school's lifeline has been involvement with university mathematics projects that provide professional development, including summer institutes and year- long seminars for teachers who want it. School boards and parents are also a critical link to what you are doing, Loftier suggested. Parents have trouble helping their kills with Math- ematics in Context not always because they don't know the mathematics, but because they are not willing to take the time to go back a few pages to un(ler- stand the concept that is being devel- oped. Right now, the job is complicated by the fact that the California State Mathematics Standards say that ah students must have algebra (lescribe(1 as a tra(litional list of skills in eighth gra(le. As for resources, the manipulatives require(1 are usually inexpensive items like string or rulers. When the Weimar Hills School was using a popular com- mercial textbook series, on the other hand, they bought boxes of materials at $400 per set, but the teachers receive(1 no training in how to use the materials. So far, the achievement results have been quite positive, with 68% of the eighth graders and 74% of the seventh gra(lers testing above the norm on the Stanford 9 Achievement Test in 1997

1998 an improvement over previous years. This improvement was notewor- thy especially because some students weren't finishing the test because they were used to using a calculator. Im- provements have been more dramatic on an algebra readiness test, which indicates that many more of the eighth graders are ready for algebra. SAXON MATHEMATICS Stephen Hake is a teacher and also a co-author on several of the texts in the Saxon Mathematics series, a program based on the principles of incremental development and continual practice. Before discussing the Saxon materials, he responded to the statement that anyone can succeed in algebra in eighth grade through persistence and home- work. In particular, Hake cautioned that some concepts and skills are prerequi- sites for algebra, and urged that some consideration be given to a diagnostic readiness test. Hake expressed appreciation for the lack of a national curriculum in the United States, because of the many varied ap- proaches an(1 opportunities for experi- mentation. He argued that decisions in California and Texas are particularly worthy of attention, because those deci- sions shape the kinds of instructional materials that become available to the rest ACTION CONFERENCE of the county. The text-book adoption process, for example, is sometimes merely a check-list. Instead, Hake ar- gue(l, adoption (recisions should be supporte(1 by efficacy studies, so that publishers win write not for the check-list, but for effectiveness. Hake emphasize(1 that in his writing for Saxon Publishing, he wrote for his own students, working out of his own class. All he cared about was effectiveness in real classrooms. Skills can be taught, Hake proposed, but concepts are much harder to teach, and so they must be teased out. Saxon materials ask several questions about the same concept, anti ask them in (lifferent ways. That way, the concept is approached from many (1ifferent angles. The primary method of instruction is through the questions that we ask students to solve. TEACHERS AND TEACHING The afternoon pane} (liscussion was begun by Anne Bartel, Mathematics Project Manager at SciMath MN in Minnesota. She discussed issues that arise during implementation of a new program. Many of the issues, she pointed out, are intimately tied to people's belief systems. For example, ones vision of algebra often depends upon whether ones definition of math- ematical understanding is focused on

skills or whether it includes something broader like "algebraic thinking." All of today's proponents of algebraic thinking came through a skilIs-focused curricu- lum. Why then, she asked, do some teachers move to algebraic thinking while others stay focused on skills? Barte} pointed out that the goal of "algebra for all" is undermined by peoples' commitment to past practices and varying standards for different groups of students. Some parents say, "algebra for all? Why isn't my kid still special anymore?" Others say, "If this curriculum is good enough for the kids in inner-city Minneapolis, then it is not good enough for us in the suburbs." To overcome these beliefs, Barte} discussed various ways of marketing the message of "algebra for all" to other audiences: community advisory groups, brochures, parent meetings, posting student work in hallways, teacher to teacher conversation, and even cIass- room newsletters. Through any of these approaches, the message should be clear, she urged, focusing on why, what, how, and what results should be expected. By using an array of these approaches, one can acknowledge the political nature of the process of change, at the department, school, district, and state levels. At any level, one or a few people can derail change. Barte} closed her presentation by discussing some characteristics of THE NATURE AND IMPACT OF ALGEBRA effective professional development. The algebra must be made explicit, because teachers don't necessarily see the aIge- bra in integrated curricula. Further- more, instructional strategies must be made explicit, because instructional modeling alone is not sufficient enough for teachers to see and internalize goals that are broader than skins. The profes- sional development must be an ongoing program rather than occasional isolated workshops. Teachers should spend some time as "students" so that they might relearn algebra in new ways and make new connections. The learning environment must be safe so that teach- ers have opportunities to engage and discuss their learning and their prior misconceptions. The teachers should have opportunities to assess student work so that they might broaden their sense of what students can do. The primary focus should be on mathematics content and instructional strategies that promote higher-order thinking. And finally, the teachers should be given sufficient time several years before significant results are expected. GIFTED AND TALENTED PROGRAMS Vern Williams spoke from his per- spective as Gifted and Talented Coordi- nator, Longfellow Intermediate School,

Falls Church, Virginia. He called himself a traditional teacher. Through the new mathematics and the back-to- basics movement, he managed to teach the same way. During his presentation, Williams emphasized that there are children who need more than the norm. Truly gifted students, he said, need an emphasis on theory, structure, and problem solving. In third grade, they hear of this mystical thing called algebra. But when they get there, they realize that they've seen many of the ideas before. And then there is calculus. Neither algebra nor calculus is a big deal for these students. They live to know why, and so we can stress proof. Students may need to know some things to prepare for the 2ist century, but these students couldn't care less whether a skill or concept wait help them shop at the supermarket. These students need an algebra course in order to reach the place where they can make up their own theories. When they can tell good reasoning from faulty reasoning, then they wait bring in their ideas and present them to the class. These students need to learn problem solving; they need a course that gets them fired up about mathematics. If you give them problems that they can't do in five minutes, they wall complain at first, but after a few months, they will ACTION CONFERENCE never go back. Algebra should be offered in 7th grade for gifted and talented students. It is not as possible to get arithmetic problems that provide the same kind of engagement. Algebra opens up the universe. If you have a successful mi(l(lle gra(les algebra program for gifted and talented students, and you want to implement algebra for all, just don't take away the gifted an(1 talente(1 option. These students need to be challenged every day, not just once a week. These kids need to get to a point where they can't do a problem and need to have another student or a teacher help them. Some of the kids in MathCounts, a national mathematics contest for sev- enth and eighth graders, will tell you that their mathematics classes are a waste. The only challenge they get is after school. Williams believes this should happen in mathematics class. COMMENTS ABOUT ALGEBRA AND EQUITY Nancy Doda, Ph.D., is an Assistant Professor of Education at National-Louis University at the Washington, DC Center, who has spent much of the last ten years working in middle school professional development. After ac- knowledging that many of her positions were contrary to those of Vern Williams,

she urged participants to stay true to principles when considering various proposals for implementing algebra in the middle grades. If we believe in the principle of curricular integration, for example, then we must ask whether it is ever appropriate to pull kids out to study algebra. If we are concerned that gifted kids are bored in class, Doda urged, we should also be concerned about bore dom for all students and in all classes. The curriculum is lifeless and dull for too many of our young people, and dull pedagogy is far more dangerous than the absence of a separate algebra class. She agreed with Williams that truly gifted kids need to be accommodated, and asked why that couldn't happen in a regular classroom. Doda pointed out that the practicalities of scheduling often create equity issues. At many schools, for example, the algebra students are all on one team, and the students who take band are all on that same team. This creates elitist subschools that are clearly distinguishable by social class. With such separation, students are not afforded equal educational opportuni- ties, and yet some of these schools that so schedule claim that they don't track. We lose minds by the year, Doda said, because we are so preoccupied with sorting and labeling kids. We also loose the greatest potential of democratic THE NATURE AND IMPACT OF ALGEBRA education which is our charge to ad- dress diversity with equity, to build discourse in that context, to create community and harmony where there is otherwise (livision. RESPONSES As Organizer of the action confer- ence, Hyman Bass, professor of math- ematics at Columbia University, led the closing (liscussion by focusing on several dilemmas and questions to be considered regarding the place of algebra in the middle grades. In educa- tional discussion and debate, there is a strong tendency to polarize issues, to contrast competing perspectives. At the Convocation, the contrast was between attention to students and attention to subject matter. The question, Bass proposed, should not be which one to choose, but rather how to make (leci- sions that pay attention to both. How (lo we properly atten(1 to the needs of students at both ends of the spectrum? Can we serve a broa(1 range of students in the same classroom? Some participants believed that it is possible by careful task selection, by posing tasks that can be approached at multiple levels anti that provi(le multiple branches. But (toes such an approach pay a (lisservice to "algebra for all"? Many schools provi(le unequal re

sources in sports and music. Should it be acceptable, then, to provide extra resources for students who show talent in mathematics? CONCLUSIONS Although the participants were aware that the action conference was not designed to draft recommendations, many participants expressed a desire for help in making decisions back in their schools and districts. Thus, the remainder of the afternoon was devoted to discussing what kinds of statements would be reasonable and useful for schools and districts who were consider- ing implementing algebra in their middle grades. There was acknowledgement that the array of approaches is broad and uncon- nected, so some participants wanted to press for more cohesion in the system. Other participants asked how policy might promote higher understanding for kids more symbol manipulation and increased enrollment in higher level courses wait not be sufficient. The remainder of the discussion fell into three broad areas: mathematics con- tent, curricular design, and use of research. Mathematics Content. Although the discussion was about algebra, many ACTION CONFERENCE participants thought about mathematics content broadly, asking first, ' What is the quality mathematics that all middle school chil(lren should learn?" In considering the subsequent question, "How is algebra part of this?" partici- pants recognized that algebraic thinking has early roots and that algebra at the middle grades will likely be different from algebra at high school or at col- lege. There was broad sentiment that our notions of algebra should expand to include the various views and ap- proaches that were presented. First, as a mathematical (liscipline, algebra has a more or less well-(lefine(1 historical definition, based in the theory of equations, symbolic representation of mathematical quantities anti concepts, formal manipulation of symbolic repre- sentations, an(1 structural analysis of symbolic systems. Second, in traditional school textbooks, algebra took a form that was innuence(1 by but (1ifferent from the historical (definition. Thir(l, in some of the newly developed curricula, algebra has been (lefine(1 as searching for patterns in (lata anti mo(leling, an(1 functions. Fourth, algebra may be seen as a too} used extensively in the sciences anti more broa(lly in business an(1 the workplace. These four approaches are (listinct, and all are e(lucationally viable. The choice must be base(1 on a mixture of mathematical, historical, pe(lagogical, anti social criteria.

Curricular cIesign. After choosing a view of the mathematics content, there are questions of implementation of that content i.e., where algebra is situated in the curriculum. As for the organiza- tion of the mathematics curriculum in the middle grades, the typical high school courses (Algebra I, geometry) may be transplanted down a grade or two. Alternatively, algebra might be one of several strands that are developed over a number of years in an integrated mathematics curriculum or even in an integrated mathematics/science cur- riculum. On another dimension, there are decisions to be made about appro- priate expectations for symbol manipula- tion and about the interplay between abstraction and placing ideas in context. Research. Many participants expressed a need for resources, re- search, and impartial observers to help in decision making. Some participants expressed the desire that decisions be informe(1 by research, past anti ongoing, on assessment and evaluation of various interventions. Other participants urged that one should also consider research on student learning, teaching, imple- mentation, and staff development. Still others expressed a need for research on current practices. There was broad sentiment that decisions be informed by better understandings of what research THE NATURE AND IMPACT OF ALGEBRA says, of what can be expected from the research, and of what research needs to be done. Because teaching and learning are very complex phenomena, much e(luca- tional discussion, policy, and research employs a typical problem-solving strategy: break the problem into small pieces that we can handle. What often results from this strategy, however, are recommendations anti policies that encompass necessary but not sufficient conditions for effective learning. Disag- gregation of effects won't help us understand how to improve student learning; sufficiency comes from the combination. In other words, the har(lest part is implementation putting the pieces together effectively, without circumventing the central e(lucational goals. With so many good new ideas on the table, what kin(1 of evidence anti what kinds of conclusions can we (lraw about the effectiveness of changes in this very complicated educational system? And how do we compare different approaches when their goals are so (lifferent? More to the point, partici- pants were looking for guidance on how to scale up these promising programs to realize improved mathematics learning for more students. Perhaps this action conference can provi(le the beginnings of answers.

r - ~ ~ ~ ~ 1 - L~-~ 'm 61 . lurid Synthesis by Sandra Wilcox Department of Teacher Education, Michigan State University INTRODUCTION Currently, considerable attention is focused on middle grades education and particularly mathematics education. Results from NAEP (Reese, Miller, Mazzeo, & Dossey, 1997) and TIMSS (National Center for Education Statis- tics, 1996, 1997) provide overwhelming evidence that far too many youngsters in our nation's middle schools are under- achieving in most areas of mathematical competence and understanding, espe- cially in using mathematical knowledge and skills to solve relatively complex, multi-step problems. The statistics are particularly alarming for poor students and students of color. At the same time, there is growing evidence that young- sters can achieve at high levels when schools provide quality mathematics programs and teachers prepared to teach students this mathematics (Hunt- ley, Rasmussen, Villarubi, Santong, & Fey, 1999; Hoover, Zawojewski, & Ri(lgway, 1997; Hiebert, 19981. In response to this mounting evidence, states anti local school (1istricts are (leveloping stan(lar(ls that set high levels of achievement for all students. The National Science Foundation has fun(le(1 several curriculum (levelopment projects aimed at creating standards-based programs of instruction. Assessment tasks and monitoring instruments are being developed for high-stakes, on- demand and classroom-based assess ments that are aligned with standards- based curricula and that provide oppor- tunities for students to show what they know and what they can do. The Na- tional Convocation on Middle Grades Mathematics Education (which pre- ceded the Action Conference) drew over 400 educators to Washington to consider the following question: What might a mathematics program look like that is developmentally responsive, academi- cally excellent, and that seeks social equity for all students?

Alongside the considerable activity aimed at improving mathematics cur riculum, teaching and learning in the middle grades, there is a concern within the research community that major work is required to better understand and articulate the assumptions that underpin this activity. The Action Conference on Research on Teaching and Learning Mathematics in the Middle Grades was designed around the question: How can we build a new program of research that integrates theory, research, and practice in mean- ingh`! ways for the improvement of mathematics teaching and learning at the middle grades? Embedded within this question are several key issues: · What is the place of theoretical frameworks and practical problems in shaping research activity? · What major theoretical perspectives underpin research on teaching and learning? Are some theoretical foundations less developed or less understood? To what degree is there consensus? · What role do problems of practice play in research? · If research is situ ate(1 in, grows out of, and informs theory and practice, how can we better articulate the relation- ship or interface among theory, research, and practice? The Action Conference brought together approximately 30 professionals including mathematics educators and teachers, mathematics education re- searchers, curriculum (levelopers, administrators, and representatives from the National Science Foundation and the Department of Education. The group was charge(1 with: 1. making suggestions to those in the field about what further research is needed, and 2. advising the Department of Education anti the National Science Foundation who wait jointly issue a paper anti an REP for an upcoming fun(ling initiative, on where strategic investments in research might be ma(le. Several experts were invited to make presentations that would tease out some of the complexity in tackling these issues. The invited talks were orga- nized to move from broad theoretical anti practical issues on how to a(l(lress research to specific research efforts (one on learning using the case of rational number anti proportional reasoning, the other on linking research on teaching to research on learning in the context of teachers' use of cognitively challenging problems), to the applications of research knowle(lge to recent curriculum (levelopment projects. RESEARCH IN THE TEACHING AND LEARNING OF MATHEMATICS

SUMMARY OF INVITED PRESENTATIONS Useful features of research. lames Hiebert described a tension between solving practical problems and doing good research (Hiebert, 1999; Stigler and Hiebert, 1999; Greenwald, Pratkanis, I~ieppe, anti Baumgar(lner, 19861. Hiebertidentified three sources of the tensions: · perceptions of minimal impact of research on solving problems of practice, fueled by inadequate com- munication to interested audiences, particularly the challenge of talking to the general population about what we know, · confusion between values, which research cannot settle, and empirical issues; and · a genuine dilemma that is inherent in the research process, the tension between addressing daunting, complex problems anti (1oing good research. Hiebert suggeste(1 a framework to better understand and resolve tensions by moving research from: · what works to understanding what works; · critical experiments to continuing programs of research; ACTION CONFERENCE · feature-base(1 to system-base(1 class room research; · researcher-driven to a teacher-driven research anti (1evelopment enterprise. BuiIcIing a stronger theoretical base for arc! through research. Alan Schoenfeld responded to Hiebert's comments by proposing a schema around the space of issues embedded in the question 'VVhat are the characteris- tics of research that would be helpful anti informative for teaching mathemat- ics in the mi(l(lle gra(les." Schoenfel(1 suggeste(1 that the current state of theoretical work on un(lerstan(ling schools, students, teachers, anti instructional materials and the relationships among them is uneven; so too is the research base and the degree to which underlying as- sumptions have been articulated or justified. He argued that major work is nee(le(1 on: . · continuing the study of learning, focusing on key concepts, · basic anti applie(1 studies of teaching in context, which should lea(1 to theories anti mo(lels of teaching, knowledge trajectories, theories of competence, of change, anti of development, · principle (1 research an (1 (1evelopment studies of materials (levelopment that yields knowledge anti principles, anti

ProbIem-cIriven research. Mary Kay Stein drew on her work in the QUASAR project to highlight how research often grows out of and at- tempts to solve problems of practice (Stein, Grover, Henningsen, 1996; Henningsen and Stein, 1997; Stein and Lane, 19961. Drawing on her study of teachers' use of cognitively challenging problems as a case of linking research on teaching to research on learning, Stein argue(1 that cIassroom-base(1 research can: · uncover anti illuminate patterns of teaching practice that may be prob- lematic in terms of student learning, · contribute to better un(lerstan(ling anti (1escribing these practices, an(l, in turn, · be helpful in (resigning interventions to reshape practices that better support student learning.

the considerable research knowledge produced by colleagues in the Rational Numbers Project and instead com- mented on how their thinking has been changing. Key pointsincluded: · There is no ladder or stages of devel- opment through the middle grades curriculum, but rather many interlinked concepts and representa- tional systems that we need to better understand. · We need to be more explicit about the big ideas in the middle grades cur- riculum and figure out how to present those ideas in ways that parents and the community understand. · Using what students are doing with high-quality tasks in classrooms may be a useful site for the professional development of beginning and experi- enced teachers. Using research to shape cur- ricu~um cIesign. lames Fey and Koeno Gravemeijer, developers on the Connected Mathematics Project and the Mathematics in Context Project, respec- tively, described the ways and the extent to which research on rational number and proportional reasoning shaped design decisions in their projects. Fey noted that many theoretical ideas (e.g., constructivism, conceptual and procedural knowledge, multiple representations, research on coopera ACTION CONFERENCE five learning, teacher change and school change) guided the develop- ment of the grade 6-S Connected Mathematics curriculum. In the area of proportional reasoning, the design- ers drew on research and theory in the literature where it seemed useful, as well as their own earlier curriculum experiences in this area (Lambdin and Knapp an, 19971. Gravemeijer described the influence of the developmental research con- (lucte(1 at the Freu(lenthal Institute on the design of Mathematics in Context. Specifically, the curriculum is undergirded by a theory that children learn mathematics by mathematizing their own activity. The theory of instruction embodies a cyclic process of spiraling through thought experi- ments (about student thinking) and teaching experiments, where teachers develop their own theories of learning for their classrooms. The (levelopers (new heavily on the work of Streeflan in the area of rational number (Gravemeijer, 19981. Fey emphasize(1 that as curriculum (levelopers, they nee(le(1 to know how well their materials worke(1 for purposes of improving the product. He argue that the classrooms in which new curriculum materials are used provide opportunities for research anti for testing the robustness of our theories. He suggeste(1 two kinds of activity:

. Studies of implementation e.g. how do teachers interpret the intent of the materials and how does this shape their use of the materials; what is the relation between teachers' knowledge and their practice; what role does context play and what features are particularly salient. · Studies of student learning what do these materials contribute to deepening students' understanding of big ideas. Echoing earlier comments, Fey noted that conducting research on either is messy. Deepening teachers' knowIecIge of mathematics It is well known that a serious impedi- ment to improving the learning opportu nities for youngsters is teachers' own lack of mathematical knowledge. Judith Sowder presented findings from a two- year project aimed at having teachers explore some of the complex mathemati- cal ideas that are typically a part of the middle grades curriculum (Sowder, Philipp, Armstrong & Schappelle, 1998; Sowder & Philipp, in press; Fennema, Sowder, & Carpenter, in press; Thomp- son, 19951. While the outcomes of this stu(ly were very encouraging (e.g., teachers began to see questioning as a teaching approach and started to listen to their students more closely), the number of participants (5 teachers and a team of researchers) raised issues about the costs of taking this level of work to scale. RECOMMENDATIONS FROM THE PARTICIPANTS The participants made recommenda- tions in three areas: teaching and teacher learning; student learning; and communicating with a variety of inter ested constituencies. Teaching arc! teacher learning 1. Especially in the light of interna- tional comparisons, it is essential to re- think both theoretical and pragmatic assumptions about the nature of profes- sional competency and growth, begin- ning with pre-service experience and continuing through the development of true competency. 2. We need models of teaching that help us better un(lerstan(1 how teaching works, and what kinds of knowledge, beliefs, and goals lead or enable teach- ers to do or not do certain things. 3. We need to better understand the bases of "good teaching," including the bodies of knowledge that are central to "good teaching" (e.g., teachers' knowl- edge of mathematics, of students, and of students' understanding of mathemat- ics; learning how to listen to students). 4. We need models of how to im- prove teaching that include descriptions RESEARCH IN THE TEACHING AND LEARNING OF MATHEMATICS

of trajectories for teachers' professional growth (what is appropriate to learn at different points in a teacher's career), how to support communities of inquiry for continuing professional growth. 5. We need to better understand what the system needs to be like, in order to take the best prepared novice and support her/him. 6. We need to better understand what makes rich teaming environments for teachers (including standards-based curriculum materials), what they learn in these environments, and how to scale up this activity. This includes understanding productive connections between re- search and professional development. 7. We need to develop research tools and methodologies for examining and describing complex settings like classrooms. 8. We nee(1 to enlist teachers as colleagues in developing knowledge about these issues. Student learning 1. We know a lot about student thinking in some domains of the middle grades curriculum. We need to expand this knowledge to other content areas as well as across content domains 2. Much of what we know about student thinking has unstated premises (e.g., social anti instructional conditions are assumed) and we need to be ready to question what we know. ACTION CONFERENCE 3. We need to broaden the "we" in the research community. We may learn that there is more shared knowledge than there is share(1 theoretical commitment. 4. We nee(1 to combine mo(le} buil(l- ing with mode} testing. 5. We need to better understand whether and in what ways reform curricula support the development of mathematical power for all students, particularly poor students, students of color, and students with special needs. 6. We need to look at good teaching as a context for student learning. 7. We nee(1 to learn more about distributed learning communities, and about the relation of individual thinking to shared social practice. Communicating with various constituencies Here we raised a number of issues. 1. Who are we doing research for? 2. What does it mean to do system- atic research? What is the role of collaboration between teachers and researchers? 3. Does our research address problems that are widely recognized as significant? Do we know the concerns that parents have and how concerns change? 4. How do we package what we believe is useful and compelling for others (e.g., school boards, parents, commu- nity)? How do we present date thatis credible and acceptable to the public?

Synthesis by Megan Loef Franke, University of California, Los Angeles and Deborah Ball, University of Michigan National attention to teaching, higher student achievement, and the need for more and better-qualified teachers is on the rise. Professional development and teacher education are of increasing interest and concern. All the concern for professional development is occurring at a time when views on teacher learning con- tinue to evolve. The change that teach- ers are being asked to make in order to enact standards-based reforms are ambitious and complex (Little, 1993; Cohen and Hill, 19981. Little points out that the current reforms require teach- ers "to (liscover anti (1evelop practices that embody central values and prin- ciples." Here teachers are seen as learners, "teaching and learning are inter(lepen(lent, not separate functions... [teachers] are problem posers and problem-solvers; they are researchers, and they are intellectuals engaged in unraveling the process both for them- seives anti for [their stu(lents]" (Lieberman & Miller, 19901. The Action Conference on Profes- sional Development was (lesigne(1 to afford an opportunity to examine promising approaches to professional levelopment. The premise was that extant knowI- edge about professional development is underdeveloped. Ideology and belief all too often dominate practice and policy. The Conference was intended to create an analytic and practical conversation about the sorts of opportunities in professional development most likely to lea(1 to teachers' learning anti improve- ments in their practice. With a focus on mathematics at the mi(l(lle gra(les, the structure of the Action Conference was groun(le(1 in analysis of the practice of teaching middle grades mathematics, considering the major tasks teachers

face and what knowledge and skill it takes to perform those tasks. This analysis of teaching practice was used to take a fresh look at the kinds of opportu- nities for learning that teachers need. What does teaching cIemanc! of teachers arc! what cIoes this imply for teacher learning? Deborah Ball, as conference leader, framed the workshop discussion with the diagram (Figure 11. Ball pointed out that the focus of the discussion through- out the workshop would be from the vantage point of teacher educators, and would consider sites through which teachers might most profitably learn mathematics content needed in teach ing, based on tasks which teachers regularly do as part of their teaching. Participants observed that the diagram helps make clear that the content to learn becomes more complex at each level. Schoolchildren are learning mathematics. Teachers are learning about mathematics, but also about children's learning of that mathematics, and about the teaching of that math- ematics. The diagram does not incorpo rate all elements of what would be needed in a national infrastructure for systemic change. It depicts relations among learning mathematics, learning to teach mathematics, learning to teach about the teaching of mathematics. Ball in(licate(1 that mathematicians, mathematics education researchers and teacher educators have all created lists specifying knowle(lge for teachers. Although these lists enable profession- als in the field to discuss content in professional development, these lists are not grounded in an analysis of the work of teaching. Such lists tend not to consider questions about the math- ematical content knowledge that is necessary in the context of teaching or the knowledge of mathematics required when teaching extends beyond how to a(l(1 fractions or identify geometric patterns. It includes being able to frame a mathematically strategic question, come up with the right example, con- struct an equivalent problem, or under- stan(1 a chil(l's non-stan(lar(1 solution. The kind of mathematical knowledge it Figure 1. Teaching, Learning, and Learning to Teach Mathematics PROFESSIONAL DEVELOPMENT OF TEACHERS OF MATH EMATICS \

takes to teach a problem goes beyond knowing the content that the students are learning, and includes the capacity to know and use mathematics in the course of teaching. Participants considered the implica- tions of this perspective on mathemati- calknowledge. In the practice of teaching, the teacher's mathematical knowledge is called upon in many different ways in figuring out what a student means, in listening to what students say, in choosing and adapting mathematical tasks, and in knowing whether the students are understand- ing. How do teachers use their knowI- edge of the content, their knowledge of pedagogy anti other knowle(lge in an interaction with their students? How do they decide which students' ideas to pursue? How do they decide which paths will further the particular content in which they are engaged? How do teachers decide what a student means by a question or an answer, or judge whether students actually understand the concept in question? It is in these interactions that knowledge of the content is critical. Ball, together with Joan Ferrini- Mun(ly, Center for Science, Mathemat- ics and Engineering Education at the National Research Council, led an activity designed to engage participants in considering mathematics knowledge as it is used in one task of teaching. Ball ACTION CONFERENCE presented a mathematics problem and asked participants to solve the problem and to describe the mathematical territories into which it might head. I have some pennies, nickels, and climes in my pocket. I put three of the coins in my hand. How much money conic I have? (NCI~M, 1989) Having analyze(1 the mathematical territory of the problem, participants were then asked to make a "downsized or unsized version" that was mathemati- cally similar in structure. The partici- pants considered what students might say or do. Was making the problem more complicated numerically a means of "upsizing"? What (li(1 it mean to make a "similar" problem, anti what sorts of mathematical knowle(lge anti reasoning did it take to do this? Participants discussed different versions of the problem and considered the mathemat- ics they used to create and evaluate them. What cIo we know about professional cIeve~opment, teacher learning, arc! the improvement of practice? Although there is a lot of professional development in the U.S., much of it is ineffective. Approaches to professional development in the U.S. are often fragmented and incoherent, with little basis in the curriculum teachers will

have to teach. Much professional development centers around features such as manipulatives or cooperative groups rather than on the substance of improving students' mathematics learning. Generally, evidence about the effects of professional development on student achievement is scattered and thin. Too often, professional develop- ment is defined by belief and propa- gated by enthusiasm. Some profes- sional development works, but there is a large gap even between effective profes- sional development and changes in practice. Often teachers view the focus of mathematics professional development as engaging in process: learning how to be a mathematics teacher or figuring out what the process of teaching should look like. Yet as teachers identify process goals, the substance of the process is left unchallenged. Teachers need opportunities to think about how the processes in which they engage serve the students' [earning as well as their own, how the processes relate to the mathematical ideas, student think- ing, and mathematical discourse. As one example, Ball cited the Cohen and Hill (1998) study in California that found that professional development that was grounded in the curriculum that teachers had to teach that is, provided teachers with opportunities to learn about the content, to learn how children think about that same content, and to learn ways to represent that content in teaching made a significant difference in student scores. Their findings indicated that professional development that made a difference provided opportunities to learn that · grounded content in the student curriculum; · were about students' thinking about that content; were about ways to connect students and content; · and were situated in context, materi- als, and sites of practice. . OPPORTUNITY TO LEARN SITUATED IN SITES OF PRACTICE The Action Conference explored the promise and potential problems of situating opportunities for teachers' learning in practice. Much teacher professional development offers teachers the opportunity to learn a new idea or activity and transfer that idea to their classroom. Professional development focused on helping teachers develop expertise within the context of their practice emphasizes the interrelationship of ideas and practice. Some professional developers engage teachers with cases of teachers engaged in teaching mathemat- ics and discuss what the teacher did and PROFESSIONAL DEVELOPMENT OF TEACHERS OF MATH EMATICS

why. Some professional developers engage teachers in the curriculum that they are going to teach and use that as the practice context, while others engage teachers with video examples of cIass- room mathematics practice, or some with student work. Each of these situates opportunities for teacher learning in practice. In each case the teacher is pushed to consider how the mathemati- cal ideas play out in the context of teaching mathematics, and they are competed to consider the details related to the students' thinking, the nature of the mathematics and its relation to their instruction. Each of these approaches affords opportunities forIearning. Each holds pitfalls that might impede such learning. Critical questions then are: How might the potential affordances be exploited? How might the potential pitfalls be managed? To learn more about what people are trying and how it is working, anti to sharpen the ability to examine their own designs and practices as professional developers, participants engage(1 in several examples of profes- sional development projects. WRITTEN CASES Margaret Smith, Pennsylvania State University, engage(1 the participants in a case study of student work The Case of Ed Taylor; Smith, Henningsen, Silver, & ACTION CONFERENCE Stein, 1998) and worked through the S Pattern Task (Figure 21. Analyzing student responses le(1 the participants to discuss the importance of the mathemati- cal knowledge of the teacher in analyzing the mathematics students do. The partici- pants offered the foLow~ng potential affordances for professional developers using cases as a medium for learning. Cases offer the possibilities of metacognition about the mathematics, provi(le an in-(lepth look at the mathemat- ics because the student thinking in the case is visible; provide the opportunity to study the particular mathematics involved in the case in context, provide an opportu- nity to read mathematics, can be used in many ways with different groups including administrators, and create opportunities to learn mathematics in teaching. Potential pitfalls included the challenge of asking questions that focus on the mathematics, focusing more on pedagogy than the mathematics, making the best use of lime, hard to read mathematics, and the fact the teachers may not know the mathematics. C U RRIC U LUM-MATE RIALS Karen Economopoulos, TERC, en gaged participants in an experience designed to show how curriculum materials might serve as a site of practice where teachers might learn mathematics in their work. Economopoulos posed two

How might these materials influence or support a teacher's daily decisions? Potential affordances to exploit suggested by the participants included: The material speaks directly to the teacher; the mathematics is very near the surface, new materials generate thinking and learning. It is possible for administrators to see more depth in the mathematics. Materials can provide the opportunity to see a broader view of mathematics. Materials can move the mathematics preferred by the teacher forward. Conti- nuity is built into the lessons; the com- mon material promotes communication among the teachers. The pitfalls to be managed included the forgoing: It is easy to turn the search for the mathemat- ics into a make-an (l-take situ ation (levoi of thinking. If teachers (lo not un(ler- stand the content, using the materials to focus on the mathematics might increase frustrationIevels. Re-learning familiar materials might result in resistance. In some tasks, it might be easy to avoid the mathematics. VIDEOTAPES OF TEACHING AND LEARNING Nanette Seago, Mathematics Renais- sance Project, engage(1 participants in examining a videotape of a professional (levelopment workshop, "Facilitating the Cindy Lesson Tape." The teachers had previously viewe(1 a videotape of an eighth gra(le math lesson. The tape PROFESSIONAL DEVELOPMENT OF TEACHERS OF MATH EMATICS

provided an opportunity to consider the challenges of using videotape as an instructional medium in professional development. Watching this video focused on the task of "facilitation" of a teacher group discussion and raised explicit issues about the challenges of keeping the professional development work centered on specific learning goals teachers' learning of mathemat- ics, for example. There was considerable interest expressed in the potential of videotape as a medium and discussion about its role in helping teachers think about their practice. Seago encouraged the viewers to think back to the framing diagram of the conference and the use of video in the context of teachers as learners. Affordances cited included the opportunity to look at a shared instance of teaching, to see mathematics in use by teachers and students. Some of the pitfalls included the problem of keeping teachers focused on particular content, questions about the quality of the teach- ing portrayed, anti the (difficulty of concentrating on the mathematics in the midst of the many other things to watch. REFLECTIONS ON THE IMPROVEMENT OF PROFESSIONAL DEVELOPMENT A panel, moderated by Mark Saul, from BronxviDe Public Schools, consisting of ACTION CONFERENCE Iris Weiss, Horizon Research; Stephanie Williamson, Louisiana Systemic Initiative; and John Moyer, from Marquette Univer- sity, reacted to the issues raised at the Conference through the lens of their experiences. Weiss, from the perspective of large scale research about implementa- tion, argued for the need to help teachers develop some way to filter and make decisions. She also raised a concern about the issue of scale; how to move from a teacher and a classroom to the system, and in the process, the need for a central vision an(1 coordination an(1 for some form of quality control. Weiss in(licate(1 her belief that the issue is a design problem. Professional develop- ment mo(lels (lesigne(1 for a best case or for small numbers (lo not work when scaled up. Moyer, resecting on profes- sional development done with urban, large city mi(l(lle gra(les teachers, in(li- cated that scaling up had to be done creatively and in small steps. Leaders who had been developed from earlier small projects became facilitators in the larger one but also remained as part of the ca(lre of learners. He observe(1 that one of the most successful efforts was to observe teachers as they taught, with the observer writing down what the teacher sai(l. When the observer later aske(1 why the teacher ha(1 use(1 those wor(ls, the teachers began the process of resection on their practice that le(1 to some lasting changes. Williamson (lescribe(1 the work

As a LASIP systemic initiative and the focus on consequence, professional developers leacher consent knowledge. Williamson noted that the guidelines for the program require collaboration among school systems and universities and stimulated partnerships among K-12 and higher education. An outgrowth of the programs has been the development of a "Core of Essential Mathematics for Grades K-~" that focuses on growth of important ideas across grade levels and is now guiding decisions for both professional develop ment and preservice programs about what teachers need to know and be able to do to teach these concepts in depth. At the close of the panel, Nora Sabelli from the National Science Foundation discussed the new opportunities for research on middle grades mathematics in the Department of Education/ National Science Foundation Research Initiative. She indicated that the focus of the initiative will be on long-term agendas, strategic plans for implementa tion, and ensuring that there is the human, methodological and institutional capacity for converting schools into learning communities. SUMMARY Participants discussed the lack of must use their work with teachers as sites for ongoing learning and re- search as they create opportunities for teachers to learn working to ensure that those opportunities impact teach- ers' knowledge and practice as well as student achievement. Professional developers are expected to work with large numbers of teachers and do so quickly. Under these conditions, professional developers have the opportunities to see themselves as learners. The Action Conference did, however, take seriously professional development as a field and attempted to create a frame for thinking about theoretical, research, and practice- based learning. Most professional development providers are convince(1 that the approaches they take enable teachers to learn and students to benefit; other- wise, they would not pursue the ap- proaches. However, little is known about what various approaches afford or do not afford, especially in relation to classroom practice and student achievement. Little is known about the details of the various approaches to professional (levelopment. The mes- sage as the field considers the issues raised at the Conference is to reflect on opportunities for professional develop- the circle of learners and on their PROFESSIONAL DEVELOPMENT OF TEACHERS OF MATH EMATICS

relation to middle grades mathematics and to each other, to design research studies around professional develop- ment approaches, and to think deeply about the mathematics middle grades teachers need to know to teach well and how they can come to know that mathematics for themselves.

Mathematics Education in the Middle Grades: Teaching to Meet the Needs of Middle Grades Learners and to Maintain High Expectations In September 1998, the Math Science Education Board National held a Convocation on Middle Grades Mathematics that was co-sponsored by the National Council of Teachers of Mathematics, the National Middle School Association, and the American Educational Research Association. The Convocation was structured to present the teaching of middle school mathematics from two points of view: teaching mathematics with a focus on the subject matter content or teaching mathematics with a focus on the whole child and whole curriculum. This book discusses the challenges before the nation's mathematical sciences community to focus its energy on the improvement of middle grades mathematics education and to begin an ongoing national dialogue on middle grades mathematics education.
