Abstract: | In this study, we consider the potential of multimedia cases as tools for teacher professional development. Specifically,
we examined online and face-to-face discussions that occurred within groups composed of pre-service mathematics teachers,
in-service mathematics teachers, mathematicians, and mathematics teacher educators. Discussions within these heterogeneous
groups tended to focus on issues of classroom implementation of the tasks shown in the multimedia case. Secondary foci of
discussion included task characteristics and appropriateness of tasks for engaging students in thinking about mathematical
concepts and processes. Analysis of contributions to discussions across group member type revealed differences that suggest
that the variety of backgrounds and experiences of group members can blend in ways that support rich and critical discussions
of mathematics, teaching, and learning. |
