Abstract / Summary

Students often use lecture recordings to learn and revise. This approach, however, demands time to locate and review relevant topics. The automatic reduction and indexing of lecture recordings, then, could focus students' attention on the most relevant content. This article investigates whether lecture recording reduction leads to improved learning outcomes on an undergraduate computer networking module. Students participated in a randomized trial which compared lightly edited full lecture recordings to those that had been significantly reduced in duration and indexed. A pre-test conducted after the initial lecture series was followed up with a post-test after several weeks of using the recordings. The results show a statistically significant difference between the groups in terms of perceived effort. However, only the students with little prior knowledge showed a statistically significant difference in learning outcome in favor of the reduced lecture recordings. Moderating factors, such as prior knowledge, warrant further research to help elicit design guidelines to inform the design and deployment of future lecture video reduction approaches.
