Benefits of Peer Learning and Learning by Teaching for Students Learning through Instructional Videos

The present study investigated the effects of peer learning and learning by teaching on students' learning through instructional video. A between-subjects experiment with peer learning (virtual peer vs. no peer) and learning by teaching (with vs. without) as factors was conducted. Students' attention (i.e., percentage of dwell time), judgements of learning, and learning performance were measured. Results showed that, no difference was found in percentage of dwell time on the contents; a main effect of peer learning on judgements of learning was found, and who viewed the instructional video with a virtual peer reported higher level of confidence; and a main effect of learning by teaching on learning performance was found, that students who viewed the instructional video with learning by teaching got better performance than who without the strategy. Our findings highlight the positive influence of peer learning and learning by teaching on students' instructional video learning.
