Although decades of mathematics education reform supports using effective classroom discourse to increase students' learning of mathematics, research about what mathematics students learn in such classrooms is less developed. Moreover, how teachers actually facilitate classroom discourse and navigate through unpredictable terrain to develop…

This study investigated preservice teachers' perceptions of their knowledge and development resulting from analyzing student work in an undergraduate mathematics education course. Participants were given opportunities to view and analyze student work examples that portrayed errors in thinking as well as alternative solution methods.…

This article provides an initial comparison of the Principles and Standards for School Mathematics and the Common Core State Standards for Mathematics by examining the fundamental notion of slope. Each set of standards is analyzed using eleven previously identified conceptualizations of slope. Both sets of standards emphasize Functional Property,…
