Examining the impact of lesson study on teachers' professional development: A quasi-experimental study
Abstract
This study sought to examine the impact of lesson study on teachers’ professional development. For this purpose, a quasi-experimental design involving 46 English teachers from 24 primary schools in Bahir Dar city, Ethiopia, was employed. Data were collected through questionnaires and analyzed quantitatively using means, standard deviations, independent samples t-tests, and pair sample t-tests. The findings of the study revealed that the teachers in the experimental group who participated in the lesson study intervention demonstrated better professional practices than those in the control group. This improvement was evident in the teachers' ability to prepare lesson plans, deliver classroom teaching, and reflect on lesson plans. Furthermore, the pre-test and post-test results of the experimental group showed that teachers had demonstrated better performance after the intervention. Generally, the study highlighted that a well-planned and implemented lesson study program can have a positive impact on the professional development of teachers.
