Abstract :

The purpose of this study is to examine the lesson plans related to teaching the radical expressions developed by the three mathematics teachers who participated in a lesson study for improving their knowledge of student thinking. The participants of the study which was a case study design were three mathematics teachers working in a high school. The data were collected from the group discussions in the planning and revision meetings, the lesson plans of the two- hour research lessons and the two-hour revision lessons, the observations of these lessons and the teachers’ reflective diaries in the scope of the first cycle of the lesson study. The data were analyzed by using descriptive analysis in the context of the lesson plan’s segments of getting started, working on it and closure. The teachers prepared a lesson plan for teaching radical expressions by using the lesson plan guide which enabled to focus on the students thinking prepared by using the literature. The plan was revised and improved by the reflections made after one of the teachers implemented the plan in the research lesson and other teachers and the researchers observed the lesson by focusing on the students’ thinking. The revised plan was implemented, then the new necessary changes were discussed at the reflection and improvement meetings and the final plan about teaching the radial expressions was designed. It is thought that the lesson plan will be guide for mathematics teachers and researchers in both teaching the radical expressions and planning a lesson focused on students’ thinking.
