Fractions are core content of elementary school mathematics, and conceptual knowledge of fractions is essential when developing a comprehensive understanding of fractions. Previous research, however, has indicated limitations in student teachers' fraction knowledge. This study investigated 57 Swedish elementary school student teachers' conceptions…

Over the past decade, there has been unprecedented regulation of initial teacher education (ITE). The objective of this study was to generate an in-depth understanding of the structural challenges faced by tertiary educators as they responded to a federal policy and a related state government policy in teacher education. The policies imposed on…

Using a product-based teacher professional development workshop in the Just Do Math program as a case, this study investigated the discourse between teachers and teacher educators from three perspectives, namely focus, form, and flow, to see how the two cohorts communicated in the co-construction, whether the co-construction is feasible to produce…

The study reported in this paper applies the commognitive theory as a lens to study teacher learning in lesson study to better understand how and why teachers learn from lesson study. Video recordings were made from reflection meetings in three lesson study cycles with a group of four Norwegian lower secondary school teachers, one person from the…

In this quasi-experimental study involving 23 fourth grade teachers, we investigated the effect of implementing teacher-child dynamic mathematics interviews to improve mathematics teaching behavior in the classroom. After a baseline period of 13 months, the teachers participated in a professional development program to support the use of dynamic…

Research on practice-based mathematics teacher education has identified core practices, principles and design features that lead to effective programs. Yet, some teachers do not perceive such practice-based development programs as relevant or useful. In response to this, the study reported in this article investigated three Norwegian teachers'…

A study of pre-service primary school teachers' content knowledge regarding real numbers related to infinity, i.e., division by zero and denseness of the real number line, was conducted at a Swedish university. Data were collected twice during the respondents' teacher education using questionnaires and interviews on both occasions. The data were…

School mathematics leaders have an important role supporting teachers to improve student-learning outcomes, yet little is known about their professional goals or the challenges they face. The study reported in this paper examined school mathematics leaders' views by analysing the qualitative responses of 193 primary and secondary leaders to two…

With the growing emphasis on early mathematics education, it is imperative to explore the preparedness of early years mathematics pre-service teachers in relation to content knowledge, beliefs, and dispositions. Therefore, this mixed-methods study explored Lebanese pre-service teachers' mathematics dispositions and efficacy beliefs in the context…

Australian students' attitudes to mathematics are in decline relative to other countries. Their participation in senior secondary mathematics that provide pathways to further study is also falling. Pedagogical approaches that improve students' attitudes to mathematics and knowledge of mathematics are required. This paper reports on preservice…

This study sought to investigate what dimensions of didactic-mathematical knowledge preservice teachers discussed when engaged in lesson study and how lesson study supported the preservice teachers in implementing reform-minded teaching of mathematics. We employed an interpretive case study methodology with the intent of conceptualising the lesson…

The purpose of this paper is to describe some contingent moments during an in-service primary teacher's lesson on area, to analyse the teacher's responses, and to examine the relationship between the teacher's mathematical knowledge in teaching and her responses to these contingent moments. The teacher, in a public primary school located in…

The pre-service teacher followed in this paper aimed to act as an agent of change during a time of reform in Irish secondary mathematics education. A teacher-researcher led action research project was conducted to depict the reality of the situation regarding the implementation of mathematical problem solving from a variety of perspectives-namely…

This paper investigates, using a case study methodology, the impact of formative video feedback on the educational experiences of early childhood and primary pre-service teachers (PST) completing a pedagogically focused mathematics education unit in a fully online mode. Given the trend over the past 10 years towards the delivery of university…

In this article we propose the notion of differentiation from an advanced standpoint as a teaching strategy, particularly valuable for working with students with low prior attainment. The notion arose from an enactivist analysis of the work of three teachers, engaged in action research in their own classrooms. All three teachers chose to teach…
