RICOSRE for the Empowerment of Students’ Creative Thinking Skills.

Creative thinking skills are one of the skills that are urgently needed in the 21st century. Creative thinking skills do not appear suddenly, but require facilitators to empower them, one of which is the application of learning models that have the potential to enhance creative thinking skills. This study aimed to examine the effect of RICOSRE on the tenth graders’ creative thinking skills, compared to PBL and conventional models. This study involved 86 students from Public Senior High School Number 1 (SMAN 1) Turen, Indonesia, and employed a pretest-posttest non-equivalent control group design. The pretest and post-test consisted of 8 essay questions each. The students’ scores were analyzed using ANACOVA and LSD test. The results indicated a significant effect of RICOSRE on the students’ creative thinking skills. The students’ average score on creative thinking increased considerably (76.59%) on RICOSRE and PBL (12.72%) and decreased in conventional learning by 3.96%. RICOSRE can be implemented to empower students' creative thinking skills. These results indicate that RICOSRE learning has the most significant influence on creative thinking skills.
