A rising number of (online) learning scenarios feature video-based worked examples. We analyzed the effects of the presentation mode of worked examples on their effectiveness and efficiency in two experiments with university students (N[subscript 1] = 57; N[subscript 2] = 43). The students acquired argumentation knowledge by self-explaining…
