One danger of integrating inquiry-based problem-solving activities into mathematics lessons is that different strategies could be accepted without in-depth discussions on the cogency and efficiency of the strategies. To overcome this issue, Japanese teachers typically go through a series of lesson-study-based teacher learning sessions and learn…

For early childhood, the domain of geometry and spatial reasoning is an important area of mathematics learning. Unfortunately, geometry and spatial thinking are often ignored or minimized in early education. We build a case for the importance of geometry and spatial thinking, review research on professional development for these teachers, and…

This is an intervention study that explored the effect of using video lesson analysis methodology (VLAM) on the ability of prospective middle/high school mathematics teachers to analyze mathematics teaching. The sample of the study consisted of 26 female prospective mathematics teachers enrolled in a methods course at the United Arab Emirates…

This article focuses on elementary school teachers' preferences for mathematically based (MB) and practically based (PB) explanations. Using the context of even and odd numbers, it explores the types of explanations teachers generate on their own as well as the types of explanations they prefer after reviewing various explanations. It also…

Current reform efforts call for an emphasis on the use of representation in the mathematics classroom across levels and topics. The aim of the study was to examine teachers' conceptions of representation as a process in doing mathematics, and their perspectives on the role of representations in the teaching and learning of mathematics at the…

Two collegiate mathematics courses for prospective elementary and middle grades teachers provide the context for the examination of Mary Boole's construct of teacher lust. Through the use of classroom observations and instructor interviews, the author presents a refined conception of teacher lust. Two working aspects of the construct were…

This article presents the results of an investigation carried out across 20+ country-regions under the auspices of ICMI Study 15 into the structures, approaches and general characteristics of the mathematics preparation and development of teachers. We use a global framework provided by the larger research literature on teacher education to…

Actor-network theory is a way of describing and understanding the complexity of social change. This article explores its relevance to understanding teacher change in mathematics education by considering a single teacher change narrative. This is centred on a veteran teacher of mathematics who participated in a teacher led,…

This article reports on a study into how collaborative contexts influence the professional development of an early-career primary teacher, Julia. We describe the process of change by which Julia manages to make her planning to teach mathematics more flexible so as to adapt to student difficulties, and we analyse the role that joint reflection…

Change in mathematics teachers' practice is often characterized as something that takes time and sustained intervention. In this article, I present the results of research that highlights a different kind of change--a profound change that takes place very quickly. Based on the analysis of 42 cases of such rapid and profound change, I also present…

In the current shifts in mathematics classrooms, teachers are challenged to use effective pedagogy to develop inquiry communities in which all participants are offered opportunities to engage in the reasoning discourse of proficient mathematical practices. The challenge for teachers is to know how to implement these pedagogical changes. This…

This article examines mathematics teacher collegiality by focusing on both the ways in which teachers interacted as critical colleagues in a long-term professional development project and the evolving role of the teacher-educator-researcher as the facilitator of this project. The professional development collaboration comprised two phases: one…

The study reported here concerns 4 years of collaboration between secondary school teachers and academic researchers, constituting an emerging community of inquiry into mathematics teaching. In the article, the process of forming of this community is discussed, focusing on the reflective activity developed by its members as well as the tensions…

This article deals with issues that are central to changed mathematics pedagogical practice. It engages general debates about teaching reflexivity and within that, more specific debates in relation to identity. It uses theoretical concepts derived from Lacanian psychoanalysis as a way of understanding what structures a teacher's narrative about…

In this review essay we critically examine issues raised by authors whose work is published in the two Special Issues of "JMTE" (Part 1, 13.5 and Part 2, 13.6) on Mathematics Teacher and Mathematics Teacher Educator Change--Insight through Theoretical Perspectives. While the authors have drawn on a wide range of theories and approaches, we have…
