Development of Organic Chemistry Module with 4D Model to Improve Students' Creative Thinking Abilities

The aims of this study were to determine the level of feasibility of the modules developed and to increase students' creative thinking skills in the Organic Chemistry of Natural Products subject. Module development was carried out with the 4D model, namely Define, Design, Develop, and Disseminate. The feasibility of the module could be determined through the validation test with expert judgments. The ability to think creatively by students was measured using descriptive questions based on creative thinking indicators, fluency, flexibility, and elaboration. Measurements were made by comparing the results of the pretest and posttest. Next the results were tested for normality and hypothesis testing using the SPSS 20 program through the One Sample Kolmogorov-Smirnov Test. Based on the validation test by expert judgments, the modules that have been prepared have a module level of eligibility which was very valid or very feasible. The average for each indicator of creative thinking at pretest and posttest has increased. The pretest and posttest values on fluency indicators were 15.31 and 35.62 with N-gain 0.78 high category, flexible thinking (20.62 and 62.81 with N-gain 0.88 high category, and elaboration) 33.43 and 61.24 with N-gain 0.73 in the high category. After the normality test, and the hypothesis test, it was concluded that there was an increase in students' creative thinking abilities in the Organic Chemistry of Natural Products course with the use of modules
