This article presents findings from a study examining teacher talk in the early and late phases of a 4-year project in a Norwegian elementary school where Lesson Study was used as a method for professional development. The study focuses on inclusive and adapted education and aims to explore the changing beliefs about student needs and the…

Purpose: The authors investigate the use and potential of a theoretical combination of Realistic Mathematics Education (RME) and the Theory of Didactic Situation (TDS) to support Lesson Study (LS) in upper secondary mathematics. Design/methodology/approach: Case study performed by university researchers, based on theoretical analysis and case…

Scaffolded faculty development is a recognized approach for enhancing teaching practices. Aga Khan University (AKU) adopted this method to elevate the quality of teaching and learning practices, promote a culture of excellence in higher education, and establish a sustainable faculty development model. AKU's scaffolded faculty development approach…

As part of its project on instructional leaders at the middle tier, International Institute for Educational Planning (IIEP) and Education Development Trust (EDT) conducted case studies in five jurisdictions, exploring the professional practices and perceived impacts of instructional leaders and the enabling factors present in the systems in which…

Lesson study has been implemented in schools around the world as a method of professional development for teachers. Lesson study consists of five steps, among which the "Research Lesson" and "Post-lesson Discussion" are central. During the Post-lesson Discussion, after the teacher has commented on the lesson, all of the…

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…

Purpose: This exploratory study investigates the extent to which lesson study (LS) in initial teacher education (ITE) teams address subject-pedagogical aspects during their conversations and what subject-pedagogical aspects are addressed. Design/methodology/approach: The two-case design of the study--one LS team in ITE comprised of an ST and…

Lesson study (LS), a teacher-oriented, student-focused professional development (PD) approach that originated in Japan, has spread globally. However, existing literature on the implementation of LS and its effectiveness provides inconsistent results, suggesting a need to review current research on LS. With a focus on LS in mathematics education,…

Although the effects of Lesson study (LS), a teacher collaborative professional development approach, on teacher professional learning and students learning have been widely documented, the theories for understanding of LS has just emerged as a research field. Interconnected Model of Teacher Professional Growth (IMPG) and Documentational Approach…

Purpose: The aim is the introduction of lesson study (LS) in geometry in Malawi secondary schools supported by a teaching framework that includes a focus on language responsive teaching. Design/methodology/approach: The study reports an LS on geometry for professional development (PD) of secondary teachers. Data analysed includes lesson plans,…

Purpose: This study aimed to evaluate the impact of four cross-institutional teaching enhancement projects (TEPs), a relatively new form of professional collaboration. The focus is on the impact at departmental, institutional and cross-institutional levels because such impact is the main reason for establishing cross-institutional TEPs.…

Identifying effective professional development related to providing social-emotional support in early childhood classrooms is a critical need. We used a multiple probe across participants and behaviors design to examine the impact of external coaching support on classroom coaches' use of coaching strategies with teachers in childcare programs. As…

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 purpose of this study is to explore how lesson study (LS) can be transitioned to an online mode, with the purpose to derive recommendations for performing online LS while being loyal to the defining elements of a face-to-face LS. Design/methodology/approach: A theoretical analysis into the core components and procedures of LS resulted…

Background: Collaboration among teachers is now considered a marker of effective schools and key to creating successful professional learning opportunities. However, the nature and efficacy of collaboration vary widely, and research suggests that collaborative efforts often fail to promote teacher development. Purpose: This study draws on…
