Students’ creative thinking skill in the flipped classroom-blended learning of mathematics based on lesson study for learning community

Abstract

Abstract Creative thinking skill is a thinking skill that generates new idea by combining any existing ideas to solve problems by using non-algorithmic, unusual, and unique methods. This research aimed to explore the development of mathematics learning instruments with the flipped classroom-blended learning based on lesson study for learning community and its implementation effect on students’ creative thinking skill. This research is multiphase mixed method research. This research was begun by research and development using 4D models to develop the learning instruments. Furthermore, a quantitative quasi-experimental research was conducted with non-equivalent pretest-posttest control group design. This research subject were 96 students on Class VIII at State Junior High School 2 Panji 2019/2020 academic year, consist of three treatment classes with two experiment classes and one control class. The research data were collected by questionnaire, observation, test, and interview. The research data were analysed statistically by Kruskal Wallis test. The results of this research show that (1) the mathematics learning instruments were valid, practically, and effective, and (2) the Kruskal Wallis test obtained significance value 0.017 (p<0,05), which indicated the implementation of the flipped classroom-blended learning model based on lesson study for learning community has significant effect on students' creative thinking skill.
