Effects of a video-based lesson on physics students' learning gain
This study aims to assess the effectiveness of educational videos in teaching and learning the concepts in standardized Physics curriculums. To evaluate the cognitive effect from watching educational videos, the researchers opted to using a pretest-posttest design. The researchers gave Grade 12 students (N = 73) a ten-item questionnaire pertaining to the topic of the presentation: black holes, before and after watching the assigned educational video. The researchers found out that watching educational videos resulted in a significant increase in performance.
