Pedagogical mediators for mathematics teacher learning: comparing four representations of practice and conceptual frameworks

At AERA 2023, SIG-RME hosted a poster symposium (Garner et al., 2023) titled
Expanding Coaching and Representations to Support Teacher Sense-Making Toward Disrupting Inequitable Mathematics Teaching Practices.

In this conceptual study, we continue and expand last year’s conversation, positioning the construct of representations of practice for teacher learning within the broader notion of pedagogical mediators. We provide categories to delineate their essential aspects and use these categories to compare and contrast four pedagogical mediators for mathematics teacher learning. Finally, we discuss implications for teacher learning with pedagogical mediators
