Using multimedia cases for educating the primary school mathematics teacher educator: a design study

The overarching goal of this chapter is to better understand how multimedia video case studies can support the professionalization of primary-school-mathematics teacher educators. We investigate the use of multimedia cases to support teacher educators in learning to mathematize and didactize and to learn how to use multimedia cases with their student teachers. The research study has an exploratory character; we will present a framework for the use of multimedia cases as a tentative answer, grounded in the researchers’ experiments and design activities.
