摘要：The purpose of this study was to determine the level of quality of the modules developed and the ability of creative thinking of students in KOBA courses. Module development is done by 4D model, namely define, design, develop, and disseminate. The quality of the module can be identified through validation tests with education expert lecturers and chemists. The ability to think creatively is measured using description questions based on indicators of creative thinking, namely fluency, flexibility, and elaboration. Measurement is done by comparing the results of the pretest and posttest. Next the results were tested for normality and homogeneity. Then hypothesis testing is carried out. Based on validation tests by expert lecturers, the modules that have been compiled are known to have good module quality levels. The average pretest and posttest scores were 56.046 and 72.549 respectively. After testing for normality, homogeneity and hypothesis testing, it was concluded that there was an increase in students' creative thinking skills in KOBA courses using modules.
