Development of Mathematics Module Based on Creative Problem Solving in Elementary Students

Teaching materials in the form of modules are very important to be used in the learning process, especially in mathematics subjects at elementary schools. This study aimed to develop creative problem solving (CPS) based on mathematics learning materials. Method used Research & Development (R&D) with Four-D consisted of 4 stages of development, namely: Define, Design, Develop and Disseminate. The number of participants in this study consisted of 30 students from grade V elementary school consisted of 19 female students and 11 male students. Based on the results of the limited trial analysis, it was found that the module used was valid and reliable with a note that it could be used with revisions. The results of the analysis on the module teaching materials product test were valid and reliable category and used without any revision. The results of the development of the module device that is applied to the creative problem solving model in students improve problem solving abilities by 85%, this shows that students' problem solving abilities are classically complete
