Prior research highlights a positive effect of incorrect worked examples on mathematics learning. Yet the mechanisms underlying these benefits are unclear. To investigate potential mechanisms of the benefits of various worked example types, we examined process data from a previously published classroom-based experiment. More specifically, we…

Appreciation of problem structure is critical to successful learning. Two experiments investigated effective ways of communicating problem structure in a computer-based learning environment and tested whether verbal instruction is necessary to specify solution steps, when deep structure is already embellished by instructional examples.…

Investigates the effects of an advance organizer lesson, presenting high-order science concepts and an elementary problem solving strategy for determining causal relations on children's use of operations of exclusion (as defined by Inhelder and Piaget, 1958). Results suggest that acceptable solutions to problems requiring the operations of…

Theories--based on concretizing, assimilation, and structuring--of the use of metaphors in learning are assessed. Each is shown to predict different patterns of inferences and errors in problem solving. An experiment with 43 undergraduates involving college lectures indicated that structuring may provide the most important function of metaphors in…

Effects of author-generated and learner-generated elaborations on subjects' abilities to recall, classify, and apply conceptual knowledge were compared for 94 college undergraduates studying a passage on psychological concepts. Author-generated elaborations and specific elaboration activities produced superior effects in comparison with…
