USING ASSESSMENT TOOLS FOR TEACHER LEARNING PURPOSES.

This paper offers a socio-cultural perspective on the mechanism by which research-based assessment tools designed to evaluate mathematics teaching, are used as pedagogical tools for teacher learning. This process is exemplified by the Realization Tree Assessment tool (RTA), showing how pre-service teachers refer to the pedagogical messages valued and devalued by the assessment tool, and which conflicts between these messages they attend to.
