Pengembangan Media Pembelajaran Fisika Mobile Learning Berbasis STEM-PBL untuk Meningkatkan Keterampilan Berpikir Kritis dan Kolaborasi

This study aims to develop a mobile learning-based physics instructional media using the STEM-PBL approach to enhance the critical thinking and collaboration skills of Grade XI students on the topic of thermodynamics. The research employed a development method adapted from the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The development process was carried out to produce and evaluate the feasibility and effectiveness of the learning media. The trial was conducted in two stages: small-scale and large-scale testing. The validation results indicated that the media is categorized as highly feasible. The product's effectiveness was analyzed using the N-Gain test, with results showing a gain score of 0.59 in the small-scale trial and 0.62 in the large-scale trial, both classified as moderate effectiveness. Furthermore, collaborative learning activities showed improvements in joint decision-making, task completion, respecting others’ opinions, and sharing ideas. Based on the results, the mobile physics learning media developed with the STEM (Science, Technology, Engineering, and Mathematics) approach is considered feasible and suitable for classroom use.Kata kunci: STEM-PBL, Keterampilan Berpikir Kritis, Kolaborasi Abstract.
