This study was prompted by students’ low cognitive abilities in solving physics problems, particularly those related to global warming. The research aimed to determine the extent to which a flipped classroom strategy assisted by Edpuzzle video annotations could enhance students’ cognitive abilities. A quasi-experimental design with a control group pretest-posttest approach was employed. The sample comprised 70 tenth-grade students from public high schools in Bandung City. Data were collected through essay-based cognitive tests, an instrument assessing the feasibility of video annotation media, and classroom observation sheets. The n-gain formula was used for data analysis. The results showed a moderate improvement in students’ cognitive abilities. Both the video annotation media and the flipped classroom strategy were considered feasible, with nearly all planned activities successfully implemented. Overall, integrating a flipped classroom approach with Edpuzzle video annotations proves effective in improving students’ cognitive abilities on global warming topics.
