The impact of lecture chunking format on university student vigilance: Implications for classroom pedagogy

Andrew Harris, Sarah Buglass, Georgina Gous
2021 Journal of Pedagogical Sociology and Psychology  
Key findings indicate that presenting the material as smaller separate video units increased the perceived achievability of the learning outcomes and reduced the number of attention lapses experienced,  ...  but not the duration of those lapses, all measured via self-report single-item measures.  ...  Within the video recording, the lecturer prompted students to pause the video and take a five-minute break three times: at the approximate (+/-23 seconds) 20-minute; 40minute; and 60-minute time point.  ...
