This research is motivated by the science learning process which is still dominated by conventional methods and limited learning media, resulting in less than optimal student engagement. This development research aims to produce interactive media through the Nearpod application based on a constructivist approach that is valid, practical, and effective using the 4D model (Define, Design, Develop, Disseminate). The results of the validity test show a very valid category with a score of 92.50% for material experts, 92.85% for language experts, and 86.11% for media experts. The results of the practicality test of teacher responses show a very practical category with a percentage of 91.66% at SDN 04 Lubuk Alung, 95.84% at SDN 17 Lubuk Alung, and 87.50% at SDN 27 Lubuk Alung. Student responses also showed a very practical category of 87.96% at SDN 04 Lubuk Alung and 97.75% at SDN 17 Lubuk Alung and 90.28% at SDN 27 Lubuk Alung. The effectiveness test through N-Gain showed an increase in student understanding with a value of 0.85 and 0.733 (high category) and 0.768 (high category). It was concluded that the constructivism-based Nearpod interactive media was valid, very practical, and effective for use in science learning for fifth-grade elementary school students.
