The purpose of this paper is to highlight similarities between Japanese lesson study, Chinese lesson study and learning study.

This editorial review is intended to stimulate a discussion about a critical aspect of both Lesson and learning studies exemplified by the texts published in issue 6.2 of this journal.

The author identifies neriage, the comparison and discussion phase of Japanese lesson study, as a critical aspect of both Lesson and learning studies and emphasises that both involve research leading to teachers learning what makes effective lessons possible. Attention is drawn to the importance of being explicit about the theory of learning behind Lesson and learning studies and how its implementation leads to teacher learning.

This editorial review provides a framework for evaluating the quality of lesson and learning studies in educational institutions.

The purpose of this paper is to describe the design and delivery of a lesson study unit in mathematics to pre-service primary teachers and to identify the opportunities and challenges resulting from the need to deliver the unit wholly online due to the COVID-19 pandemic.

Cross-case analysis, using a before-and-after design, was used to compare the development and delivery of the unit in 2019 and 2020, with the pivotal event of interest between the before-and-after cases being the onset of the COVID-19 pandemic.

The content and structure of the unit, as well as its collaborative aspects, remained substantially the same in the before-and-after cases. While there was a low level of engagement with pre-recorded lectures, there was a high level of engagement and participation in the online synchronous seminars, together with a marked increase in overall satisfaction with the unit. Pre-service teachers were unable to teach and observe one another's planned research lessons in school. Instead, after a detailed examination of the task, the lesson plan and student solutions, they observed a pre-recorded video of a research lesson at a local school and participated in a streamed post-lesson discussion. Pre-service teachers regarded this new component as a highlight of the unit and an important connection between the theory and practice of lesson study.

The inclusion of the video-recorded research lesson in 2020 introduced a new level of authenticity for pre-service teachers, allowing them to observe a high quality structured problem solving mathematics lesson taught in a local public school, as part of a local implementation of lesson study-something that is not generally possible. While there is often a view that the benefits of lesson study result mainly from collaborative planning and teaching of the research lesson, this paper highlights the value of involvement for all participants in research lesson observation and post-lesson discussion, as well as the opportunities afforded by the use of “virtual lesson study”.

The purpose of this paper is to describe the design and initial implementation of a lesson study network in the US intended to support implementation of the Common Core State Standards (CCSS).

Participant observation and artifact collection document the development of the teaching through problem solving (TTP) network over a 14-month period.

The TTP network draws heavily on Japanese practices (e.g. lesson study) and Japanese materials (e.g. coherent, focussed mathematics curriculum) to support changes envisioned in the US CCSS related to students’ mathematical practices and dispositions. The reasons for choice of these key Japanese features are explicated, and teachers’ initial reactions described.

The design shows promise for combining teacher “ownership” with implementation of high-quality approaches designed by others; and allowing instructional innovations developed in Japan to flow into US practice. TTP in mathematics has persistently resisted implementation in the US, so the network is designed to target a central problem in implementing the CCSS.

A method for instructional innovations to spread from classrooms in one country to another is suggested.

What does it take to successfully implement new educational innovation in schools, and what roles does lesson study play there? In order to answer this question, this study investigated the implementation of Sesame Street's Dream–Save–Do (DSD) curriculum that was designed to help children in a Japanese elementary school learn to pursue their own dreams.

The authors first reviewed available documents on the DSD curriculum in the district, and then conducted DSD class observations. The authors also interviewed the students, teachers, the principal, the lead teacher at the school, the school district staff in charge of the operation as well as the Sesame Japan staff in order to collect the data for the study.

The study found that students were highly engaged in open-ended discussions about their future dreams and how to achieve them in observed DSD classes. The implementation of the new curriculum benefited from utilizing lesson study as the main arena for curricular innovation. A further analysis of the data suggests that the success of the curricular innovation owed much to an inside-out implementation process that situated the iterative lesson study cycle of the teachers as the key driver of change while external actors supported the lesson study process in an inside-out fashion.

The study implies that guiding an educational innovation to success requires not only institutionalized lesson study, but also cross-institutional collaborative dialogues to support the lesson study process with mutually established trust among key players of the innovation. Further studies are needed to investigate how this model sustains as principals and how this model works (or do not work) in other pilot schools and beyond.

This study implies that what matters most is that the school embodies a vision shared among teachers, school leaders and external curriculum developers, all working together across institutions in a spirit of collaboration. This type of inside-out implementation would be a path to ensure and sustain the success for those who plan any new educational innovation.

What matters most was found to be that the school embodies a vision shared among educators, school leaders and external curriculum developers working together across institutions in a spirit of collaboration.

Guiding an educational innovation to success requires not only new ideas and effective curriculum plans but also a social structure that allows teachers to engage in effective implementations of the desired curriculum. Lesson study is often considered to be a within-school or school-to-school collaborative process. It is rarely connected to outside agents that bring in new ideas for educational innovation. This study found how inside- and outside-school actors can work together to actualize educational innovation, and what roles lesson study play there.

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.

This is a qualitative/interpretative research with a case study design, carried out with a secondary school mathematics teacher who participated in two lesson studies. Data were collected from participant observation, audio recording of lesson study (LS) sessions and discussions with the teacher, video recording of lessons and semi-structured interviews. Frameworks regarding the teachers' actions are used in the analysis.

The results suggest that in her teaching practice, the teacher led students to explain their strategies with supporting/guiding actions, but she also challenged the students to justify their productions, ensuring that the students' ideas were clear. Additionally, the teacher explored incorrect strategies and disagreements, inviting and challenging other students to intervene or react and involved students in drawing connections, as discussed in the LS. Therefore, the teacher put into practice several actions teachers can do in leading whole-class discussions to promote students' learning. Participating in LS was an opportunity to rethink her teaching practice, as the teacher pointed out, bringing her a new perspective on leading discussions in which students play an active role in learning mathematics, creating opportunities for the students to explain and react to their colleagues' ideas.

This article examines an under-researched issue: the influence of LS on the way a teacher leads whole-class discussions, during and after participating in lesson studies.

The purpose of this paper is to provide an introduction of the papers in the current issue.

By revealing contrasting features of alternative theories of learning, this paper offers a contribution to the on-going discussion about the role of learning theory in Japanese lesson study and its global adaptations.

Attempts to theorize lesson study in contrast to the theory-based learning study reveal a fundamental difference in the learning theories used to underpin this task related to the different world views on which they are founded.

This paper review provides an overview of the insights into lesson and learning studies provided by the authors in this issue of the journal.

Much has been written about the failure of curriculum reforms to bring about pedagogical transformation in classrooms. The purpose of this paper is to introduce the special issue about facilitating curriculum reforms through lesson study.

The guest editors introduce the papers while also discussing key themes and concepts.

The collection of papers shows that it would be naïve to assume that the intended, enacted and lived curriculum would be the same. Teachers play a very important role in bringing the intended curriculum to life in classrooms, and lesson study provides a process through which the intended, enacted and lived curriculum could be brought closer together.

It is only through such collaborative discourse among teachers supported by “knowledgeable others” that reform ideas can take root in classrooms and bring about lasting change.

A first post-WALS attempt at a thematic analysis of the conference presentations since its first annual meeting in 2007, this paper aims to achieve two major purposes: first, to capture the trends of spread and diffusion of lesson and learning studies globally and second, to draw useful implications for future conferences.

A thematic analysis using NVIVO12.0 coding on all forms of conference presentations found in the WALS 2019 Conference Programme was conducted. Representative cases were selected from paper and symposiums sessions to support the claims generated from the analysis.

The study provides an evidence-based confirmation of the global spread and diffusion of lesson and learning studies. It uncovers findings key to the initial spread and continued diffusion; examines funding as a mechanism enabling university–school research relationships, models of adaptations and issues of sustainability; surfaces the theoretical models and methods adopted in paper and symposia presentations. The current situation, lessons learned and possible implications for future WALS conferences are discussed.

Inform research on practical cases.

Lessons learned are discussed.

These are possible implications for future WALS conferences.

The originality lies in its being the first WALS post-conference analysis aiming at identifying substantive themes with potential to draw important implications for future research and subsequent years' conferences.

The purpose of this paper is to present French Didactique des Mathématiques (DM) to the Lesson Study (LS) community.

This theoretical paper presents the origins of DM in the Theory of Didactical Situations (TDS) by Brousseau. It elaborates about didactical engineering, fundamental situation and other fundamental concepts. It briefly presents other Didactique theories: the theory of conceptual fields, the anthropological theory of the didactic, the joint action theory in didactics and the double approach. It considers importance of the (TDS) and influences over teaching of mathematics. This paper finishes by highlighting the ways Didactique and LS could contribute to each other in a profitable dialogue.

The paper contrasts DM with some LS main features. It highlights the parallels despite fundamental differences in the initial goals of the perspectives. It shows that these differences could lead to productive dialogue by producing more practice-oriented forms of didactical engineering for the first and making teachers’ principles for lessons more explicit for the latter.

The paper presents a very quick overview of the parallels between DM and LS. Additionally, this paper gives many accessible references in English for the reader to explore Didactique further.

This paper aims to provide an overview of the origins of bansho, how it has developed to be an indispensable practice in Japan and its influence on countries outside Japan. The integration of bansho into lesson study (LS) will also be presented.

This paper draws on the vast literature on bansho from both in and outside Japan to illustrate the points mentioned above.

Recapitulation on the history of chalkboard and bansho in different eras in Japan illustrated its endurance towards the test of time, geographical space and functions. While bansho remains a constant presence in LS research, there has not been any work that outlines how bansho is integrated into the LS cycle. Thus, a guideline on how bansho can be incorporated in the LS cycle is provided.

A comprehensive overview of bansho allows educators and researchers outside Japan to move beyond the know-how and know-what of bansho; it would serve as an invaluable source to understand the core concepts underlying this classroom practice, thus avoiding the mere adaptation of bansho superficial aspects. This study also provides precise instruction on how bansho can be integrated into each step of the LS cycle, which will guide teachers and researchers in the future implementation of LS.
