Development of Problem Based Learning (PBL) Based Interactive Multimedia on the Topic of Absolute Value Equations and Inequalities Systems

Abstract

This research and development (R&D) study successfully created and validated an interactive multimedia product based on Problem-Based Learning (PBL) for teaching the topic of One-Variable Absolute Value Equations and Inequalities Systems. Utilizing the systematic Four-D (Define, Design, Develop, Disseminate) model, the study aimed to address the lack of engaging and contextually relevant instructional media in mathematics education at SMA Muhammadiyah 2 Metro. The development process involved a comprehensive needs analysis, iterative prototyping, and rigorous expert validation. The final product, available as an installable Android application (.apk) and a direct-access presentation file (.pptx), effectively integrates text, animation, images, and audio to create an immersive learning experience anchored in real-world problem-solving scenarios. Validation results from two content experts and two media experts confirmed the product's high feasibility, with average scores of 91.5% and 85%, respectively, categorized as "Very Feasible." Furthermore, a small-group trial involving seven students demonstrated its exceptional practicality, achieving an average score of 90% ("Very Practical"). These findings affirm that the developed PBL-based interactive multimedia not only meets stringent design and pedagogical standards but is also highly usable and well-received by the target learners. The study concludes that this multimedia tool is a viable and practical innovation for supporting active, student-centered mathematics instruction. Recommendations for future work include optimizing the application's file size, disseminating it through public platforms like the Google Play Store, and conducting effectiveness trials to empirically measure its impact on improving students' mathematical problem-solving abilities.
