Upaya Meningkatkan Kemampuan Berpikir Kreatif Siswa Melalui Model Pembelajaran Kooperatif Tipe Jigsaw Dengan Pendekatan Soal Open Ended Berbasis Soal Cerita

Abstract

This study aims to improve students’ creative thinking skills through the implementation of the Jigsaw cooperative learning model combined with an open-ended approach using story-based problems. Creative thinking is an essential competency in mathematics learning, particularly in problem-solving situations that require divergent thinking. The research employed a Classroom Action Research (CAR) design conducted in two cycles, each consisting of planning, action, observation, and reflection stages. The subjects were 21 eleventh-grade students. The findings show that the application of the Jigsaw model with open-ended story-based problems significantly improved students’ creative thinking skills. The average score increased from 59.2 in the pre-action stage to 72.8 in Cycle I, and further improved to 84.5 in Cycle II. Improvements were evident across all indicators: fluency, flexibility, originality, and elaboration. Moreover, student learning activity increased from moderately active to highly active. Therefore, it can be concluded that the Jigsaw cooperative learning model combined with an open-ended approach using story-based problems is effective in enhancing students’ creative thinking skills and in fostering a more active and collaborative learning environment.
