This project is engaged in the research and development of videocases as tools for teacher development in mathematics K-12. Materials will be available by June, 2002. The materials are based on short video segments of lessons from actual mathematics classrooms K-12.
Lessons focus on algebraic thinking.
Videos are accompanied by transcripts, seating charts, copies of student work, teacher interviews, commentaries, and related reading materials. They are designed for use with teachers K-12, with some videocases more applicable to either secondary or elementary audiences. The video segments are used as objects of inquiry, highlighting the complexities in teaching. This stands in contrast to the purposes for which most video has been used, i.e., as models, exemplars, or illustrators of a particular point. Teachers portrayed in the videos are individuals who acknowledge their own challenges as they struggle to improve their teaching in order that their students understand mathematics.
