The objectives of this research were (1) to study the lesson plan designing ability of the student teacher by using lesson study approach together with PLC, and (2) to study the implementing their lesson plan ability of student teacher by using lesson study approach together with PLC. The participants in the target group were the student teachers in Secondary Education Department, the Faculty of Education, Chulalongkorn University who teach in public schools and demonstration schools. The student teachers major in General Science, Biology, and Physics. The members of the professional learning community, researchers, teacher’s buddy, and mentors were participated in all 4 steps of lesson study which were (1) subject matter analysis, (2) learning activity plan, (3) instruction, and (4) reflection. The research instruments were (1) an inquiry lesson plan designing checklist, and (2) a classroom observation form. Collected data were used to collect quantitative and qualitative data. Percentage, mean score, standard deviation, and content analysis were used to analyze the collected data.

The research findings can be summarized as follows:

  1. After using lesson study approach together with PLC, the mean percentage score of student teachers’ abilities in designing lesson plans was 91.96 percent, that was at a good level, which was higher than the mean percentage score before treatment was 70 percent, that was at a moderate level.
  2. After using lesson study approach together with PLC, the mean percentage score of student teachers’ abilities in implementing their lesson plans was 92.50 percent, that was at a good level which was higher than the mean percentage score before treatment was 67.50 percent, that was at a moderate level.
