Abstract During the COVID-19 pandemic, conducting experiments in the lab has become constrained due to physical distancing protocols. Experiments activities are important to help students understand the concepts of physics, one of which is the optical learning of image formation on a positive lens. Video based experiment is one of the solutions that can be used as an alternative to do experiments activities in the laboratory due to the COVID-19 pandemic. This study aimed to design and develop a video based experiment to make students to determine focal length of a positive lens. This study used the R&D method with ADDIE development model reference (Analysis, Design, Development, Implementation, and Evaluation). According to the evaluation of material experts and media experts video based experiment covering aspects of content, material, language and presentation of media experts by 81% and material experts obtained by 84%, categorized as very high. Based on the results of the expert test, it can be concluded that the video based experiment is feasible to be used as an optical learning media for students in high school.
