In 4 experiments, participants viewed a short video-based lesson about how the Doppler effect works. Some students viewed already-drawn diagrams while listening to a concurrent oral explanation, whereas other students listened to the same explanation while viewing the instructor actually draw the diagrams by hand. All students then completed…

Animated models explicating how a problem is solved and why a particular method is chosen are expected to be effective learning tools for novices, especially when abstract cognitive processes or concepts are involved. Cognitive load theory was used to investigate how learners could be stimulated to engage in genuine learning activities. It was…

Animated models explicate the procedure to solve a problem, as well as the rationale behind this procedure. For abstract cognitive processes, animations might be beneficial, especially when a supportive pedagogical agent provides explanations. This article argues that animated models can be an effective instructional method, provided that they are…

This study examined effects of direct training and observational learning on acquisition, generalization, and maintenance of a first-aid skill for three pairs of preschool children with disabilities (three target learners and three observational learners). All six children learned the skill, generalized the skill to playground and home settings,…

This investigation examined the effect of model similarity on girls' acquisition, retention, transfer, and transfer strategies of a novel motor task. Forty girls (mean age = 10 years) were randomly assigned to conditions in a 2 (model skill level) 3 2 (model sex) factorial design using four treatment groups: (a) male skilled, (b) male learning,…
