Exploring the impact of lesson study through the views of Lao mathematics teacher educators on the needs, learning and difficulties

The purpose of this paper is to comprehensively explore the current situation of lesson study (LS) implementation and practice among Mathematics Teacher Educators (MTEs) in Teacher Training Colleges (TTCs) across the country in Laos. Moreover, the study investigates MTEs’ professional learning through LS experience, the difficulties they encountered during practicing LS and their urgent needs to deepen their comprehension in the context of LS.

Data were collected through semi-structured interview with 45 MTEs from 7 TTCs in February/March 2018 (seven weeks). The study also collected 14 LS reports, 7 LS posters from the respondents and observed one cycle of LS practice in 2 TTCs. The data were systematically analyzed using inductive category formation through the procedure of transcribing and reading the transcription, thematic coding and categorizing and interpreting the meaning of thematic ideas (Mayring, 2015; Merriam, 2009). Licensed software MAXQDA 10 was used for this qualitative study.

The study argued based on LS practice in LS model 1 and model 2. MTEs that followed LS model 1 practiced LS in a superficial aspect and quantitatively relied upon the results from the checklists. They majorly satisfied the immediate measurement of teacher teaching’s behavior and student learning’s behavior. Frequently, time constraints, writing LS reports and collaboration were the great challenges. In contrast, MTEs that followed LS model 2 practiced LS in order to deepen understanding of students’ mathematical thinking. Although LS helped them by adjusting appropriate learning task, they encountered difficulty to innovate it effectively. LS also helped them in offering students’ autonomy to explore mathematical ideas, but they failed to understand the values of utilizing students’ mathematical ideas.

The findings from this study are beneficial for LS practice in the country and similar LS initiatives to find a measure to enhance the effectiveness of LS in schools and TTCs. The study suggested providing clear details of each step, the essential aspect and the core concept of LS to MTEs for successful transposition of LS to a non-Japanese context. Providing LS advisors who have had great experience in conducting LS not just high teaching or working experience only is highly recommended. This study has a limitation in observing LS practices from all seven TTCs.

Ministry of Education and Sports (MoES) recognizes the significance of implementing LS in TTCs to enhance the quality of teaching-learning, though the progress of LS in those TTCs has not yet been addressed. Current situation of LS revealed in this study is valuable for similar initiatives, MoES and Japan International Cooperation Agency to make an effort in order to move LS forward.
