Semi-structured review on practice of lesson study in ASEAN context: A lesson from ASEAN

Lesson study (LS) became popular as a teacher professional development practice in the educational science field. LS originates in Japan and spreads beyond Japan due to its positive impacts on teaching and learning. The ASEAN countries have adopted Lesson study (LS) as a teacher professional development practice in their contexts. Although several literature reviews were conducted on the spread and adoption of LS all over the world and in developing countries, there is hitherto no geographically scoped study on LS in the ASEAN countries. This study geographically scopes eight countries out of ten ASEAN countries, namely Indonesia, Singapore, Philippines, Malaysia, Thailand, Brunei D, Myanmar, and Laos People's Democratic Republic. This study aims to overview the practice of LS and its development track in ASEAN context. The objective of the study is to point out how LS implementation has been practiced in the culturally and geographically closed ASEAN countries over time. In this study, by applying a semi-structured literature review method, the data are extracted to (1) demographic information of the reviewed articles, (2) approaches of LS adoption in each country (3) LS model structure of ASEAN countries. This study provides the overview of the developmental tracks of LS implementation in ASEAN context and overviews that the implementation of LS in ASEAN context has been introduced since 2000s and evolved over time although the developmental paces differ in each country.
