Purpose: Despite numerous kinds of research regarding the potential of lesson study (LS) in internship and microteaching in teacher education curricula, studies examining the adaptation of LS in the lesson planning (LP) course have not been established. To fill this gap, this study aims to explore the perceptions of pre-service biology teachers of…

Purpose: This study aimed to determine the expectations of students from mathematics teachers in the planning phase of lesson study (LS) in mathematics classrooms. Design/methodology/approach: This study reported only a part of large-scale action research. The participants were Grade 8 students selected by the convenience sampling method. The data…

Purpose: This paper aims to discuss the significance of teacher authorship ("jissen kiroku") developed during "jugyo kenkyu." Specifically, it explores the structural conditions of "jugyo kenkyu" that enabled the flourishing of "jissen kiroku." Design/methodology/approach: To find how "jissen…

Purpose: This paper examines how mathematics teacher educators (MTEs) learn to enact equitable mathematics instruction using technology through lesson study (LS). Design/methodology/approach: A LS team with three MTEs conducted three iterations of LS on teaching the Pythagorean Theorem in an in-person, technology-mediated environment. Many forms…

Purpose: Finding ways in which technology can be used to modify, strengthen, scale up and sustain lesson study (LS) is an emerging field of research. It has become even more important due to a pandemic leading to teacher and student learning being delivered online. The purpose of this paper is to present research findings about experiences of…

Purpose: This study determines which aspects of the intended object of learning (planned by teachers during the first phase of a learning study) is made discernible from a learners' perspective. In a learning study, the intended, enacted, and lived object of learning are considered. This study focuses on the learning material used by teachers…

Purpose: The purpose of this paper is to explore the coaching and mentoring supervision of the Lesson Study to enhance preservice mathematics teachers' research competencies. Design/methodology/approach: The researcher employed a multi-case study design to describe the internship experiences of practicing coaching and mentoring supervision while…

Purpose: This study explored how teachers change, what teachers learn and how they learn during the implementation of project-based learning through lesson study. Design/methodology/approach: In this study, three university researchers, one doctoral student and six mathematics school teachers formed a lesson study team. Using a qualitative…

Purpose: This study aims to develop a self-reflection scale useful for teachers to improve their skills and to clarify the Japanese teachers' characteristics during mathematics lesson observation (MLO). In MLO, it is important to understand the lesson plan in advance to clarify observation points, and we aim to develop a scale including these…

Purpose: The study aims to understand what learning is evidenced regarding knowledge about the teaching of mathematics by five primary teachers when they reflect on research lessons. To do so, we used situations from the formal and informal reflection sessions that took place after teaching four research lessons. Design/methodology/approach: It is…

Purpose: The purpose of the article is to identify, describe and explain what and how new mathematics teachers learn when participating in a lesson-study induction programme, by networking theories. Design/methodology/approach: To explore this phenomenon, the author combines the two theoretical frameworks, Patterns of Participation and the…

Purpose: The main purpose of this study was to explore how engaging in lesson study enhances secondary school mathematics teachers' pedagogical practice in lesson planning in Jimma, Ethiopia. Design/methodology/approach: The study employed a design-based research approach with qualitative and quantitative data collected from two secondary schools,…

Purpose: Teacher noticing is a critical aspect of teaching competence that has garnered significant scholarly attention. This systematic review aims to comprehensively analyze the integration of teacher noticing into lesson study, exploring how different stages of lesson study influence the development of teacher noticing.…

Purpose: The aim of the study is to better understand how lesson study (LS) contributes to challenging teachers' views of mathematics teaching and learning. Design/methodology/approach: This study is part of a wider ongoing project aiming at improving primary mathematics teaching in Malawi through professional development (PD) of teachers using a…

Purpose: This article aims to analyse how a teacher leads whole-class discussions during and after participating in lesson studies and to what extent that participation influences her teaching practice. Design/methodology/approach: This is a qualitative/interpretative research with a case study design, carried out with a secondary school…
