The effect of repetition on learning and retention: An experimental study about learning from video

This thesis investigates the effects of repetition on learning and retention through an experimental study focusing on educational videos. It examines how repeated exposure to video content impacts students' acquisition and retention of knowledge, guided by theories of meaningful learning and memory models. The study is significant for identifying effective learning strategies, especially with the increasing use of educational videos. By employing an experimental design, the research aims to address gaps in existing literature regarding the efficacy of repetitive viewing and contribute to educational practices by providing insights into optimizing learning and retention through repetition. The study found that repetitive watching of educational videos significantly increased test scores, with participants scoring higher after repetitive viewing (M=3.56, SD=1.19) compared to single viewing (M=2.91, SD=1.28), demonstrating a statistically significant mean increase. For future research, it suggests exploring the effects of repetition with a between-subjects design, measuring comprehension as a learning outcome, using longer and more diverse video lectures, and examining the impact of delayed testing and executive functions on learning and retention.
