This study aims to develop interactive learning media utilizing Articulate Storyline 3 integrated with a problem-based learning (PBL) model to enhance students' critical thinking skills, particularly on the topic of temperature and heat. The research employed a Research and Development (R&D) approach using the ADDIE model, which consists of Analysis, Design, Development, Implementation, and Evaluation stages. A large-scale field trial was conducted involving 100 eleventh-grade students from MAN 3 Banyumas. The implementation phase adopted a pretest-posttest control group design to measure the media's effectiveness. The results showed that the developed media is highly practical, as indicated by an average score of 90.43% from students and 93.05% from physics teachers, categorized as "very practical." Statistical analysis demonstrated a significant improvement in students’ critical thinking abilities, with a partial eta squared value of 0.949 and Cohen’s f of 4.31, signifying a very large effect size. The media features include interactive simulations, animations, quizzes, and a game-based approach that allows learners to engage in higher-order thinking through real-world problem-solving tasks. The integration of PBL strategies into interactive digital media provides students with opportunities to analyze, evaluate, and construct solutions collaboratively, fostering deep conceptual understanding.
