Adolescent reproductive health education requires engaging approaches that can effectively address both cognitive and affective learning outcomes. Although previous studies have demonstrated the potential of digital and video-based health education, evidence directly comparing audiovisual media with conventional presentation-based education in randomized controlled trials remains limited, particularly for integrated knowledge and attitude outcomes. This study aimed to evaluate the effectiveness of video-based educational media in improving adolescents’ knowledge and attitudes toward reproductive health compared with PowerPoint (PPT)-based education. A randomized controlled trial with a pretest–posttest control group design was conducted among 52 seventh-grade students who were randomly allocated to an intervention group or a control group. The intervention group received a 45-minute reproductive health education session delivered via video, whereas the control group received education delivered via PPT. Knowledge and attitude data were collected using validated questionnaires before the intervention and two weeks after it. Analysis of covariance (ANCOVA) was used to compare post-intervention scores between groups while controlling for baseline differences. The results showed that the video group achieved greater improvements in both knowledge and attitude scores than the PPT group after adjustment for baseline scores. The novelty of this study lies in the randomized comparison of audiovisual and conventional educational media while simultaneously evaluating cognitive and affective outcomes. These findings support integrating video-based learning into school reproductive health programs as an engaging, complementary strategy to strengthen adolescent health education.
