This classroom action research (CAR) was conducted to improve student learning outcomes in a vocational high school through the integration of H5P-based interactive video within a Problem-Based Learning (PBL) model. The study involved two cycles consisting of planning, implementation, observation, and reflection. In Cycle 1, students engaged with H5P videos containing embedded quizzes and participated in collaborative discussions. However, only 33.33% of students reached the minimum mastery criteria. Based on these results, improvements were made in Cycle 2, including the use of guiding questions and individual accountability strategies. The second cycle showed significant improvement, with 83.33% of students achieving learning mastery. The findings suggest that H5P-based interactive videos effectively enhance engagement, participation, and conceptual understanding among vocational students. The use of interactive video not only supports independent learning and collaboration but also stimulates higher-order thinking skills through visual, auditory, and contextual input. Therefore, integrating H5P interactive media into PBL is a promising approach for improving student performance in vocational education.
