Students’ Ideas Anticipation through Flow of Lesson in Collaborative Lessons Planning for Classroom Using Lesson Study and Open Approach

Abstract

This study analyzed students’ ideas anticipation through a flow of lesson in collaborative planning of a lesson team for a math class using a Lesson Study and Open Approach. The teacher of the classroom used the Open Approach as a teaching approach and the lesson study as an improvement of the teaching approach’s qualities. Research methodology relied on a qualitative research by employing a participatory observation in which a researcher was a member of the lesson study team, composed of five members, who collaboratively worked on the steps of the lesson study approach. Thai version of Japanese textbook was used as a principle tool for collaborative planning the lessons. The textbook emphasis on problem situations that connects the students’ daily life, as a result, the students could make sense of the problem situations. Research results found that the teacher team solved problem situations inside the textbook, then anticipated the students’ ideas through each component of the flow of lesson as follows: (1) considering representations of students’ real world to anticipate the students’ difficulties, (2) considering semiconcrete aids to anticipate the students’ ways of problem solving and (3) considering representations of students’ mathematical world to anticipate the students’ ideas. The students’ ideas focused on mathematics and emphasis on problem solving, the lesson study team, as a result, used the students’ ideas to collaboratively design other components of lesson plans for the classroom using Lesson Study and Open Approach.
