Recent efforts to help teachers improve have centered on teacher evaluation. This qualitative dissertation explored how eight teachers from one middle school described and understood improving their practice Additionally, this study used purposeful developmental sampling to explore how, if at all, participants' way of knowing (meaning their…

The purpose of this mixed-method study is to investigate and compare students' problem-solving and higher order thinking skills. This study involves two contexts: a traditional teaching program and a Lesson Study program. In qualitative phase, seven mathematics lecturers, a physics lecturer and the researcher forms the Lesson Study group and they…

Purpose: The article presents the construction of a conceptual framework, which is rooted in mathematics education and in dialogic analysis. It aims to analyse how dialogic interactions contribute to constructing teachers' mathematical problem-solving knowledge. The article provides one example of this analysis. Design/methodology/approach: The…

This study aims to present the experiences of pre-service mathematics teachers' on skill-based problem solving-oriented lesson study. In the study, the activities related to the learning environments designed by the lesson study groups before and after the research lesson with a focus on problem solving are investigated. In this way, the study…

Changes in society demand constantly evolving education systems. Teachers' practice is crucial to the successful implementation of educational reforms. A major obstacle for practicing teachers in implementing reform mathematics is that they have not experienced it themselves as learners. Consequently, teachers require extended, practice-based…

This research is to find out how to improve the performance of outstanding Raudhatul Athfal (RA) teachers in Yogyakarta and how the steps are and how the key to the successful performance of outstanding RA teachers in Yogyakarta. This research is a qualitative research through a psychological approach that is carried out directly to the object…

This article describes the New York City Community of Adult Math Instructors (CAMI), a math teachers' circle founded in November 2014. The authors share details about their own participation in CAMI to show the professional growth that research-based, peer-led professional development can offer for adult educators.

Worldwide interest in Japanese Lesson Study as a vehicle to improve mathematics teaching practice through professional learning has left largely unanswered questions about the extent to which it can be replicated elsewhere. This paper reports on a small-scale research project, "Implementing structured problem-solving mathematics lessons…

This article contributes to the discussion on mathematics teacher reflection. Reflection was included in a study of the didactisation practices of primary school mathematics teachers as one of nine didactisation practices. The study involved five volunteer primary school mathematics teachers. A qualitative design-research approach was designed…

Differential equations is a branch of mathematics which is closely related to mathematical modeling that arises in real-world problems. Problem solving ability is an essential component to solve contextual problem of differential equations properly. The purposes of this study are to describe contextual teaching and learning (CTL) model in…

Analyzing students' mathematical explanations can be a powerful tool to enhance teachers' practice, but collecting these explanations can be cumbersome. Here, we describe our quest to find effective tools to make explanations accessible to elementary (K-6th) teachers. First, we describe how digital audio recordings enabled teachers to focus on the…

This paper is based on data gathered during visits to Uganda and Malawi, conducted by the International Math-teacher Professionalization Using Lesson Study (IMPULS) project and the Japanese International Cooperation Agency (JICA). The author's observations and experiences highlighted misconceptions about lesson study. The paper concludes that some…

Learning theory provides a powerful framework for analyzing instructional consultations and increasing their effectiveness. In this paper, the authors review the main tenets of learning theory, apply them to consultation scenarios, and present a complex case study to show how they can guide analysis and problem solving around challenging…

Previous studies have reported on primary children's algebraic thinking and generalising in a range of problem settings but there is little evidence of primary teachers' knowledge of algebraic thinking. In this paper the development in algebraic thinking of one primary teacher who taught a research lesson in a Japanese Lesson Study project…

Algebraic structures are a necessary aspect of algebraic thinking for K-12 students and teachers. An approach for introducing the algebraic structure of groups and fields through the arithmetic properties required for solving simple equations is summarized; the collective (not individual) importance of these axioms as a foundation for algebraic…
