Abstract
The program of TSG 46 focused on three themes:
1. Conceptualization and theorization of knowledge in/for teaching mathematics at the secondary level.
2. Methods for measuring, assessing, evaluating and comparing knowledge in/for teaching mathematics at the secondary level.
3. Connections between knowledge and practice of teaching mathematics at the secondary level.
The first three sessions centred on the three themes, while the fourth was devoted to summary, discussion and reflections. Below we describe the activities that took place during the four sessions.
