Development of digital 3D-based learning media light materials and optical instruments utilizing holography technology to improve students' concept understanding.

This study aims to develop an Android-based science learning media and utilize 3-sided holography technology. This research is a Research and Development using the ADDIE method, namely (a) Analyze, (b) Design, (c) Develop, (d) Implementation, and (e) Evaluation. The data collection instrument used a needs analysis questionnaire aimed at teachers and students, validation instruments (specific and general) by experts, practicality tests for teachers and students, and student trials. The results of the data obtained in the form of quantitative data derived from the scores obtained and the pre-test and post-test, qualitative data derived from suggestions and comments. The product developed is the application HoloScience which includes video features, materials, and quizzes in the form of a Hologram Kit. The results of special and general validation by experts were 86.6% and 93.75%, while the results of the practicality test of teachers and students obtained 100% and 94% results, respectively. The results of n-gain get a score of 59% which is categorized as quite effective. From the results obtained, it can be said that the learning media is very valid, very practical, and quite effectively used for learning. [ABSTRACT FROM AUTHOR]
