Contexts, Forms and Outcomes of Mathematics Teacher Collaboration

This chapter synthesizes a comprehensive analysis of the papers included in Theme B of ICMI Study 25 as well as the information collected during the meeting in Lisbon. The focus of all the documents is on the forms and outcomes of mathematics teacher collaborations implemented in different contexts. The chapter elucidates the relationship between the forms of collaborative settings and their effects on the outcomes of collaboration related to teacher or student learning. We acknowledge the challenge of studying collaborative works due to its complexity and the highly contextualized aspect of the scenarios created and the results achieved. In spite of that, we provide answers to the questions proposed for Theme B, and also discuss about the need to move forward with future research on new emerging issues.
