The Effectiveness of PBL Assisted by H5P Interactive Video in Improving Mathematics Literacy of Junior High School Students

Source abstract

The low mathematical literacy of junior high school students in Indonesia remains a challenge, as reflected in PISA results that consistently place Indonesia at the bottom in mathematical reasoning. This study aims to examine the effectiveness of Problem-Based Learning (PBL) assisted by H5P interactive videos in improving mathematical literacy compared to PBL without digital media. A quasi-experimental method with a Nonequivalent Control Group Design was applied to two grade VIII classes of a state junior high school in Cirebon, each consisting of 36 students. The instrument was a mathematical literacy test based on three PISA indicators: formulating, employing, and interpreting. Data analysis included normality, homogeneity, and an Independent Samples T-Test, supported by N-gain calculation. The results showed no significant difference in pre-test scores between the groups, indicating comparable initial ability. However, the experimental class achieved an N-gain of 0.71 (medium–high category), higher than the control class of 0.38 (low–medium category), with a significance level of 0.000 < 0.05. These findings confirm that integrating H5P into PBL significantly improves students' mathematical literacy. The study concludes that interactive media serve not only as a learning aid but also as a pedagogical tool that fosters participatory, contextual, and meaningful learning, providing practical recommendations for mathematics teachers to adopt innovative digital approaches.
