Can prompts improve self-explaining an online video lecture? Yes, but do not disturb!

Markus H. Hefter, Veit Kubik, Kirsten Berthold · 2023 · International Journal of Educational Technology in Higher Education

Abstract In recent years, COVID-19 policy measures massively affected university teaching. Seeking an effective and viable way to transform their lecture material into asynchronous online settings, many lecturers relied on prerecorded video lectures. Whereas researchers in fact recommend implementing prompts to ensure students process those video lectures sufficiently, open questions about the types of prompts and role of students’ engagement remain. We thus conducted an online field experiment with teacher students at a German university (N = 124; 73 female, 49 male). According to the randoml
