A Case for Theory Development About Backward Transfer

In this chapter, I make a case for why the field of mathematics education is in need of theory development about a particular aspect of the transfer of learning called backward transfer. I begin the chapter by explaining my conceptualization of backward transfer and providing an illustrative example. Then, I present a three-part case. First, I provide an argument for why the field needs more theory development generally, and why this especially applies to theory about backward transfer. Second, I present the current state of research and theory about backward transfer in the context of mathematics education and related fields. Finally, I outline five aspects of theory about backward transfer in the context of mathematics education for which there is a pressing need for development.
