Development of 3D Motion Diorama Learning Media To Improve Students’ Critical Thinking Skills

Abstract

The research and development of 3D motion diorama media is motivated by the low critical thinking ability of grade VI students at SD Negeri 010140 Perkebunan Gunung Melayu. The purpose of this study is to develop teaching materials in the form of 3D motion diorama media on solar and lunar eclipse materials to improve the critical thinking skills of grade VI students. This research uses the Research and Development (R&D) method with the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model developed by Robert Maribe Brach. The results of the study show that first, the dioramic media developed was declared very valid by experts, with a media feasibility percentage of 93% and material feasibility of 94% while the feasibility of the instrument question was 93%. Assessment by teachers obtained an average of 97% while student assessment obtained an average of 99%. Second, classroom trials showed a significant improvement in students' critical thinking skills, with an average pretest score of 52.7 and posttest 91.7 (a difference of 39 points), and an N-Gain of 0.82, indicating a high category. The implications of the use of 3D motion diorama media are also able to improve critical thinking skills, on the other hand, also in the use of this media in understanding an eclipse concept, it is very clear and the active involvement of students is very visible. This study recommends the application of similar media in science learning to support the development of students' critical thinking skills in primary school.
