The Effect of Video-Based Learning on Elementary Students’ Learning Outcomes in Ecosystem Topics

Understanding ecosystems is not only academically important but also practically valuable in fostering environmental awareness. Knowledge of ecosystem balance can cultivate a sense of responsibility toward environmental conservation and sustainability. This study aims to examine the effect of interactive video-based learning on elementary school students’ learning outcomes in ecosystem topics. The research employed a Research and Development (R&D) approach using the ADDIE model and involved 30 fifth-grade students at SD Negeri Penuduan, Musi Banyuasin. Data were collected through expert validation, practicality testing, and pretest–posttest assessments, and were analyzed using N-gain scores and paired-sample t-tests. The validation results indicated that the developed learning videos were categorized as “very valid” in terms of content, language, and media aspects, with an average practicality level exceeding 90%. The pretest results showed an initial average score of 38, while the posttest average increased to 86.67, with an N-gain score of 0.78, which falls into the “high” category. The paired-sample t-test revealed a statistically significant improvement in students’ learning outcomes (p < 0.05). These findings provide empirical evidence that interactive video-based learning is effective in improving elementary school students’ learning outcomes and their understanding of ecosystem concepts.
