sional education of teachers?

As mathematics educators, we need to pursue the important questions and begin to develop the ideas. In your own work, try out some activity or approach centered around the kind of thinking that framed the Workshop. Document what happens and probe the effects to see what underlying factors may be present. Think carefully about the nature of the evidence you present. Write about your experiences and present your ideas to your colleagues in a variety of forums. As a community, we can begin to collect these experiences and evidence, testing our theory against the reality of teachers and students, and begin to move forward in a real analysis of what mathematics teachers need to teach well and how they come to learn the mathematics they need to know.
