This paper investigates the unexpected phenomenon that we call multiple documentational genesis, which occurred during a professional development program for in-service mathematics teachers, guided by researchers in mathematics education. It involves the proliferation of uncoordinated teaching materials created by teachers for their students based…

There now exists a sizeable body of work around student voice, predominantly through the intervention of researchers. However, given the critical role of teachers in the fruition of student voice efforts, there is a need to further our understanding of such efforts carried out by teachers themselves, particularly within non-Western contexts. Using…

This study examines the influence of teacher collaboration on novice mathematics teachers' professional development through a project in Shanghai focused on creating digital resources for global primary mathematics education. We investigated how two novice teachers' interactions with social resources shaped their didactic praxeologies in lesson…

This paper examines a professional learning (PL) program for upper elementary teachers focused on developing instructional practices to support multilingual learners (MLLs) in science. The PL sought to support teachers' praxis, which we describe as their sense of agency to critically analyze and take action against barriers to MLLs' opportunities…

The research presented in this paper aims to shed light on the complex role of mathematics teacher educators who led courses for prospective mathematics teachers. Theoretically, the research combines the documentational approach to didactics and the meta-didactical transposition frameworks, complementing the study with the analysis of the teacher…
