Purpose
– The purpose of this paper is to examine an Iranian mathematics lesson through the eyes of Japanese educators, and the critiques of Iranian teachers for raising the quality of teaching. In this paper, the Japanese lesson study process is considered as an approach to raising the quality of teaching.
Design/methodology/approach
– Qualitative methods including pre-lesson planning, peer observation of the lesson, post-lesson discussion, and semi-structured interviews with the participants of the post-lesson discussion meetings in Iran and Japan were employed for data collection. A detailed description and analysis of the lesson is provided for deep understanding of students’ mathematical communication in the class and teachers’ points of view in the post-lesson discussions about raising the quality of teaching.
Findings
– The findings are intended to clarify the significant influence that cross-cultural analysis has exerted on raising the quality of teaching and developing a culture of transnational learning that supports teachers to design appropriate learning tasks, to conceptualize mathematical phenomena, and to provide mathematical communication which encourage students to participate more in classroom activities.
Research limitations/implications
– This study provides a transnational learning opportunity for Iranian teachers to learn from Japanese educators how to deliver evidence-based analysis of a lesson for raising the quality of teaching in practice, look culturally and differently at what actually goes on in the classroom, and localize lesson study as a global approach to the “science of improvement.” However, issues to be considered in future studies include how such “small changes” can be linked together in local communities to expand the improvement from bottom up, and how to facilitate collaboration with the global community to expand transnational learning.
Practical implications
– Traditionally in Iran, there are a variety of teacher training programs but there are no examples of lesson study like those that take place in Japan as a model of practitioner inquiry for raising quality of teaching. Hence, it can be said that Japanese lesson study may provide a new approach of transnational learning in the Iranian education context for building a “science of improvement.”
Social implications
– In the case of Iran, especially at the elementary school level, teachers do not have enough preparation or experience. Therefore, raising the quality of teaching through lesson study that has an actual impact on teacher and teaching quality and developing a “science of improvement” has become a pressing concern in national and international contexts.
Originality/value
– The case study shows that the transfer of the Japanese model of lesson study plays a significant role in harnessing the potential of students and teachers as well as teachers themselves by improving teaching. Efforts by teachers to communicate and learn from each other’s strengths, in fact lead to the realizing of the students potential and thinking process. In particular, it helps supply more open-end and in-depth task learning, which anticipates student thinking, understanding, recognizing and questioning.
