Introduction to the papers of TWG20: Mathematics teacher knowledge, beliefs, and identity

Abstract

The variety of papers presented in TWG 20 at CERME 2017 connected to the growing field of teacher education. There were total of 27 papers and 4 posters that had been presented. The number and heterogeneity of the research foci, contexts, methodological and theoretical approaches, provided opportunity for in-depth discussions and reflections around the presented papers. Although the core topic proposals were expected to embrace three intertwined domains, the focus of the presented papers at TWG20 was mainly on teachers' knowledge, while the topic of teachers’ beliefs and teachers’ identity would appear implicitly or in the background of some of the research.
