Lesson Study in Schools Components Perception: The Challenge of Transforming Teaching and Learning. Objective: To explain the perceptions of school principals, teachers, staffs, and students in implementing the Lesson Study Learning Community (LSLC). Methods: This descriptive study uses a quantitative approach. The sample consisted of three schools, each school consisting of one principal, three teachers, two staffs, and twenty five students selected by purposive sampling. There are three instruments developed by researchers; perception of principals, perceptions of teachers and staff, and perceptions of students. All items were valid (P < 0.05) and all the instruments were reliable (r11 > 0.40). The data were analyzed using percentages. Findings: From the four groups of respondents showed a positive perception in the application of lesson study in each school. The lowest positive perception was in the group of staff respondents. Conclusion: LSLC in schools gets a positive perception. Despite positive perceptions, the obstacles are still high.
