A Thai Study of Mathematical Creativity of Students in the Lesson Study and an Open Approach Context

Abstract

            The purpose of the study was to investigate Thai students’ creative thinking in the lesson study and the open approach context by the participant observation and assessment of the students’ mathematical creativity. The target group was 7th grade students who had been taught continuously for six years through the lesson study and the open approach. It was the class where the teacher had experience in teaching through the lesson study and the open approach regarding the concept of Inprasitha (2011a). In addition, this school has been the model school to apply the innovation under the project of the teacher professional development with the lesson study and the open approach for over 10 years since 2006, organized by the Center for Research in Mathematics Education (CRME), Faculty of Education, Khon Kaen University. The results of the study revealed that all of the students taught in the lesson study and the open approach context had creative thinking consisting of divergence, fluency, flexibility, and originality. Moreover, the results of the study were beneficial for the Mathematics teachers to apply the instructional guidelines to their own teaching in order to encourage the students’ creative thinking.
