Asghar Salimi 3 Assistant professor of TESOL, department of English, University of Maragheh, Maragheh, Tabriz, Iran Abstract Lesson study is a recent development in Education to boost the quality of learning, but it has not received the attention it deserves in Iran. Given that the lesson study has been adapted from Japan, it is essential to examine and study its implementation and examine the strengths and weaknesses in the educational systems of different countries (Fujii, 2019; Saito, 2012; Stigler & Hiebert, 2016). Considering that lesson study has become a long-standing tradition in the Japanese educational system, and school reform and teacher education centers, the results of studies of (Emamipour & Khakbaz, 2019, Khakbaz et al., 2009, Maleki Arzin Abadi, 2016; Sobhani, 2018) showed that lesson study in Iran differs in style and implementation from that of the Japanese model and other countries. Therefore, it is necessary to study the experiences of practitioners qualitatively. Teachers sometimes face administrative difficulties and obstacles in the implementation and use of lesson study. Identifying these barriers and problems is only possible through their own experiences. Received on: 28/06/2021 Accepted on: 27/08/2021 1 . Email: firoozmahmoodi@tabrizu.ac.ir 2.
