PENGEMBANGAN MEDIA PEMBELAJARAN AUGMENTED REALITY PADA KONSEP EFEK FOTOLISTRIK DAN DIFRAKSI ELEKTRON UNTUK MAHASISWA PENDIDIKAN FISIKA
This study aims to develop a learning media in the form of an Augmented Reality (AR)-based instructional video on the concepts of the Photoelectric Effect and Electron Diffraction for Physics Education students that is valid and practical. The research employed a Research and Development (R&D) method using the ADDIE model, which consists of the Analyze, Design, Development, Implementation, and Evaluation stages. The study was limited to a small-scale trial (one-to-one evaluation and small group evaluation) without conducting a large-scale field test. The research subjects were fifth-semester students of the Physics Education Study Program at Sriwijaya University. Data were collected through expert validation sheets (content, media, and language experts) and student practicality questionnaires using a four-point Likert scale. The validation results showed that the developed media obtained a validity percentage of 90.6% from the content expert, 88.3% from the media expert, and 91.6% from the language expert, all categorized as very valid. The practicality test results in the one-to-one and small group evaluation stages indicated that the media was categorized as very practical based on aspects of appearance, ease of use, clarity of visuals and language, and its usefulness in helping students understand abstract quantum physics concepts. Based on these findings, the AR-based instructional video developed in this study is considered very valid and very practical, making it suitable as an alternative learning media for quantum physics courses in higher education.
