Pengembangan Bahan Ajar Berbasis Quizizz pada Materi Alat Pembayaran Kelas X Ekonomi di SMA Negeri 15 Medan

Abstract

Economics learning outcomes for Grade X students at SMA Negeri 15 Medan remain suboptimal, with many students scoring below the Minimum Mastery Criterion (KKM) of 75. One contributing factor is the use of basic PowerPoint presentations, which may reduce student engagement, focus, and active participation. This study employed a Research and Development (R&D) method using the ADDIE model to develop Quizizz-based teaching materials on “payment instruments” and evaluate their feasibility, practicality, and effectiveness in improving learning outcomes. The research subjects were 36 Grade X students selected from a population of 430 students across 12 classes. Feasibility was assessed by subject matter and media experts, while practicality was evaluated through teacher and student responses. Effectiveness was measured using pre-tests and post-tests. The results showed that the Quizizz-based teaching materials were highly feasible, with validation scores of 90% from subject matter experts and 88% from media experts. The product was also highly practical, receiving positive responses of 90% from teachers and 89% from students. The effectiveness test produced an N-Gain score of 0.87, categorized as high, while student mastery increased from 61.1% in the pre-test to 100% in the post-test. Thus, the Quizizz-based teaching materials are feasible, practical, and effective for improving Economics learning outcomes.
