Implementation of integrated inquiry collaborative learning based on the lesson study for learning community to improve students' creative thinking skill

Creative thinking skill is very important in the era of industrial revolution, especially in the 21^st century. Since everyone must have 4C (Creative, Critical thinking, Communicative, Collaborative). However, it is still far from the expectation that students are having this skill. Therefore, in this research, we examined the application of integrated Inquiry-collaborative learning based on Lesson Study for Learning Community to improve students' creative thinking skills. The used method was classroom action research, with two variables linear system as the material in class VIII E MTsN 5 Jember in the odd semester of 2018/2019 academic year. Students' creative thinking skills were measured by essay tests. Data were obtained through the test results of learning, observation, interview, and the results of students' activities during the learning of integrated inquiry-collaborative learning based on Lesson Study for Learning Community. The average pre-test result of the two variables linear equation system was around 22.33%. While the average post-test results turned out that the number of students who think creatively increased. This means that in the first cycle students experienced an increase in creative thinking. This shows that integrated inquiry-collaborative learning based on Lesson Study for Learning Community can improve students' creative thinking.
