Abstract
The difficulty of primary students in solving simple fractions is because students fail to understand the concept of simple fractions. Meanwhile, the results of previous studies allow the integration of PowToon animation multimedia into a constructivist approach to facilitate the conception of the simple fraction. This research aims to develop constructivist-based PowToon animation multimedia (CoPAM) as a valid, practical, and effective learning media for simple fraction material. PowToon was developed using a research and development (R&D) method with a define, design, and development (3-D) model that involved 12 fourth-grade primary students. The data analysis used was descriptive analysis with data collection methods using observation, tests (pre-test and post-test), validation questionnaires (validation of media and material experts, teacher responses, and student responses), and documentation. The results showed that CoPAM has very feasible product criteria for validity, practicality, and effectiveness to facilitate primary students in understanding simple fractions. The recommendations for the next study are needed to further develop and test CoPAM products or the like (which could go through the dissemination stage) by involving a larger and wider number of participants by testing inferential statistics.
