Abstract

This study aimed to develop and evaluate the feasibility and effectiveness of video-based learning media on the human digestive system topic. The research was motivated by the students' lack of active participation in problem-solving, low enthusiasm during the learning process, underdeveloped critical thinking skills, and difficulties in understanding the human digestive system material. Additionally, there was a lack of available video learning resources on this subject. This development research followed the Lee & Owens model, employing questionnaires and tests for data collection, and analyzing both qualitative and quantitative data. The video-based learning media was validated by media and design experts, as well as subject matter experts, and was deemed feasible for testing. Teacher evaluations categorized the media as highly appropriate, while individual student trials showed excellent results with a score of 92.77%, and small group trials yielded a score of 93.14%. The pretest-posttest analysis of students' critical thinking skills, using the n-gain test, resulted in a score of 0.60, indicating a moderate improvement. Therefore, it can be concluded that problem-based learning video media is an effective tool for enhancing students' critical thinking skills in the human digestive system topic.
