Development of Active Learning-Based Mathematics Instructional Video Media Oriented Toward Conceptual Understanding for Junior High School Students

Abstract

This study aims to develop an Active Learning-based mathematics instructional video media to enhance the conceptual understanding of junior high school students. Conducted using the ADDIE research and development model, this study involved analysis, design, development, implementation, and evaluation stages. The subjects included material and media experts, a mathematics teacher, and 32 seventh-grade students from SMP Negeri 2 Depok. The product was validated by experts and tested for practicality and effectiveness. Validation results from material and media experts scored 82 (good category) and 94 (very good category), respectively. Practicality tests showed very positive responses from both the teacher and students. Effectiveness tests, analyzed using a one-sample t-test and z-proportion test, indicated a significant improvement in students' conceptual understanding, with learning outcomes surpassing the minimum mastery indicator. The video, which integrates the five syntaxes of Active Learning Preparation, Stimulation, Exploration, Elaboration, and Confirmation is proven to be a valid, practical, and effective medium for supporting mathematics learning.
