The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal govern- ment. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the supe- rior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sci- ences to secure the services of eminent members of appropriate professions in the ex- amination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the Na- tional Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Preface T he central idea of evidence-based education--that education policy and practice ought to be fashioned based on what is known from rigorous research--offers a compelling way to approach reform efforts. Recent federal trends reflect a growing enthusiasm for such change. Most visibly, the 2002 No Child Left Behind Act requires that "scientifi- cally based [education] research" drive the use of federal education funds at the state and local levels. This emphasis is also reflected in a number of government and nongovernment initiatives across the country. As consen- sus builds around the goals of evidence-based education, consideration of what it will take to make it a reality becomes the crucial next step. In this context, the Center for Education of the National Research Council (NRC) has undertaken a series of activities to address issues related to the quality of scientific education research.1 In 2002, the NRC released Scientific Research in Education (National Research Council, 2002), a re- port designed to articulate the nature of scientific education research and to guide efforts aimed at improving its quality. Building on this work, the Committee on Research in Education was convened to advance an im- proved understanding of a scientific approach to addressing education prob- 1Other NRC efforts--especially the line of work that culminated in the recent report Strategic Education Research Partnership (National Research Council, 2003)--offer insights and advice about ways to advance research utilization more broadly. vii

viii PREFACE lems; to engage the field of education research in action-oriented dialogue about how to further the accumulation of scientific knowledge; and to coordinate, support, and promote cross-fertilization among NRC efforts in education research. The main locus of activity undertaken to meet these objectives was a year-long series of workshops designed to engage a range of education stake- holders in discussions about five key topics: Peer Review in Federal Education Research Programs. This workshop focused on the purposes and practices of peer review in federal agencies that fund education research. Federal officials and researchers considered a range of models used across the federal government to involve peers in the review of proposals for funding and discussed ways to foster high-quality scientific research through peer review. Understanding and Promoting Knowledge Accumulation in Education: Tools and Strategies for Education Research. With a focus on how to build a coherent knowledge base in education research, researchers and federal of- ficials analyzed several elements of the research infrastructure, including tools, practices, models, and standards. Fundamental questions about what such a knowledge base might look like were also considered in this context. Random Assignment Experimentation in Education: Implementation and Implications. The evidence-based education trend has brought to the fore decades of debate about the appropriateness of randomized field trials in education. Far less consideration has been devoted to the practical as- pects of conducting such studies in educational settings; this workshop featured detailed descriptions of studies using randomized field trials in education and reflections on how the current trend to fund more of these studies is influencing states, districts, and students. Journal Practices in Publishing Education Research. Following the more general discussion of how to build a coherent knowledge base in education in a previous workshop, this event took up the specific case of journals that publish education research. Editors, publication committee members, and others involved in the production and use of journal articles considered ways to promote high-quality education research and to con- tribute to the larger body of knowledge about important areas of policy and practice. Education Doctoral Programs for Future Leaders in Education Re- search. A final workshop focused on the professional development of edu-

PREFACE ix cation researchers, with a specific emphasis on doctoral programs in schools of education. Deans, graduate study coordinators, foundation officials, and policy makers came together to share observations and chart potential paths for progress. Additional information on each of these events, including transcripts of presentations and discussions, can be found at http://www7. nationalacademies.org/core/. This report is a summary of the third workshop in the series, on the implementation and implications of randomized field trials in education. Educators and researchers have debated the usefulness of these methods for conducting research in education for decades. As many more of them are being funded in education than ever before, our objective in convening this workshop was to provide a venue for researchers and practitioners who have been involved in this kind of study in educational settings to share their experiences. The event took place on September 24, 2003, at the National Academies' Keck Center in Washington, DC. This report summarizes common issues and ideas that emerged from the presentations and discussion during the workshop (see Appendix A for the workshop agenda and Appendix B for biographical sketches of the com- mittee members and speakers). These issues included why researchers use randomized field trials, when such a design is appropriate for answering questions about education, and how to implement this kind of research in an educational setting. In discussing these issues, workshop speakers identi- fied challenges to successfully carrying out randomized field trials in schools and described strategies for addressing those challenges. Although investi- gators conducting any type of research in schools would encounter many of these challenges, some are unique to this research design. While this report represents our synopsis of the key issues aired at the workshop, it does not contain conclusions or recommendations. We will issue a final report with recommendations for improving scientific research in education based on the series of five workshops. In addition, because the one-day workshop that is the subject of this report necessarily included only a small number of practitioners and researchers, this summary cannot be construed as representative of all experiences and views of those who have been involved in randomized field trials in educational settings. We did take care to invite individuals who were experienced and knowledge- able about implementing this kind of research in social settings and believe
