 Encouraging Mathematical Thinking: Discourse around a Rich Problem (21 March 2000)
 In an attempt to integrate practice and research, this videopaper by the Math Forum's Bridging Research & Practice Group (BRAP) of teacher practitioners and Math Forum Staff reports on findings culled from discussions of research articles and chapters, classroom practice, and videotapes of classroom teaching, noting links between these findings and research into student learning and instruction. It incorporates video clips from the teachers' classrooms, and provides a challenge Cylinder Problem with lessons for various levels and student predictions of outcomes. The paper was presented at a March 910 conference sponsored by TERC, Bridging Research & Practice  Videopapers in Mathematics Education, in Dedham, Massachusetts. Readers are encouraged to contribute their thoughts through a public discussion.
