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…

College students with varying degrees of prior conceptual understanding of a scientific topic were randomly assigned to a program-controlled or a learner-controlled treatment in a sequence of computer-assisted video learning. (Author/LMO)

This study focused on the transition in memory between conceptual knowledge formation and procedural knowledge development. The first variable--display time interval--controlled the amount of instructional display time of each interrogatory example; the second variable--content sequence--sequenced examples according to response-sensitive decision…

Three strategies for selecting number of instances needed to learn legal concepts were compared. An adaptive strategy required 25 percent less time and resulted in better post test performance than a partially adaptive strategy. The partially adaptive strategy was 16 percent more efficient than the nonadaptive strategy, and resulted in better…
