Interpretive Framework
The TDE interpretive framework builds on the emergent perspective and the framework developed by Cobb as described in chapter 12 herein. However, because the TDE stud—pedagogical as well as mathematical development and because that development occurs at multiple sites, the framework requires extension beyond the framework described by Cobb for studying elementary classrooms. Using a tabular structure similar to Cobb’s. this framework is outlined in Table 13.2.
