This comparative study analyzed the similarities and differences in the mathematical communication used by teachers and primary school students in Japanese, Lao, and Thai mathematics classrooms. It adopted a qualitative research design, and the targets were teachers and students in Grades 1-6 at a selected school in each of the three countries.…

The aim of this paper is to investigate and compare lessons given in primary school teacher education in Japan, Finland and Sweden. We analyse one lesson from each country and compare them using a common framework. Chevallard's anthropological theory of the didactic (ATD) is used to frame this analysis and in particular to model teacher educators'…

In this study, we aim to explore the conditions and constraints of implementing a lesson study-based professional development (LSPD) program for Japanese pre-service primary teachers. Based on the anthropological theory of the didactic--a well-established theoretical framework in mathematics education research--it offers three dimensions…

We examined the relationship between pedagogical content knowledge (PCK) test scores and elementary school teachers' psychological variables, conceptions of teaching and learning and test utilization strategy, for mathematics. Through a web-based survey, participants responded to a six-item descriptive PCK test and to inventories of conceptions of…

According to the Programme for International Student Assessment, functions constitute an important part of mathematical literacy. In Japan, students start learning about bivariate relationships in the fourth grade (at the age of 9). However, reports suggest that elementary school students and lower-level secondary school (junior high) students…

Purpose: The authors aim to determine the effects of Global Lesson Study (GLS) -- a two-year, one-cycle program defined as "international cooperative lesson study through international exchange among teachers using ICT" -- on intercultural competence for lesson study based on pre- and post-survey conducted for Japanese teachers.…

Teaching mathematics online has been highlighted as one of the solutions to the current crisis for education caused by the COVID-19 virus pandemic and subsequent school closures. However, we do not know what attitudes and experience teachers have towards online teaching. The aim of this study was to gain insights into how Japanese teachers were…

There has been a lack of research into conceptually teaching the structure of contextual problems to kindergarten students. This is despite the popularity of contextual problems and the difficulties that students have with them. This study focuses on creating a textless, image-based application that uses the Triplet Structure Model to teach about…

Purpose: The purpose of this exploratory study was to develop Global Lesson Study (GLS) defined as an international collaborative lesson study through international exchange of teachers using ICT. Its purpose is to nurture teachers from different countries with intercultural competence to conduct lesson study. Design/methodology/approach: We…

The present study is an ongoing survey targeting Japanese fifth and ninth grade elementary and junior high school students respectively using the framework of "The Third Wave" international comparative study. The purpose of this research report is to describe the questionnaire survey's results and analyze some similarities and…

With international exams (PISA and TIMSS) producing results every three or four years, there is near continual talk of East Asian dominance in mathematics education. Beyond the reporting of scores, some studies have compared mathematics teaching in these countries with U.S. instruction. However, researchers are not (usually) grade school math…

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…

This paper aims to clarify how coherence of 'structured problem solving' mathematics lessons can be produced by comparing the lessons of three teachers from a narrative perspective. Results of our analysis showed three main coherence characteristics of lesson teaching sequences: (1) sequence scenes are recursively developed based on the previous…

What is the product of Lesson Study? Lesson Study is a scientific activity for teachers based on the methodology introduced in the 1880s. In Japan, research topics for Lesson Study are usually shared through the regular revisions of the curriculum and the research movement of several societies. As a result of teachers' efforts to overcome…

In this paper, we first present a theoretical approach to study mathematics teacher knowledge and the conditions for developing it, which is firmly rooted in a systemic approach to didactic phenomena at large, namely the anthropological theory of the didactic. Then, a case of open lesson is presented and analysed, using this theoretical approach,…
