Using Worked-Out Examples Of Written Explanation For Writing-To-Learn In Evolutionary Biology, Amy M. Yu

Electronic Thesis and Dissertation Repository

Content learning can be enhanced through writing-to-learn. Research into cognitive load theory suggests that the use of backwards faded, worked-out examples increases schema acquisition and concept transfer. However, these effects have not yet been demonstrated for writing-to-learn, particularly for the conceptual understanding of evolution. The effects of two writing conditions were investigated in a pre-test post-test quasi-experimental design. Groups in two conditions wrote explanations of evolution using six Darwinian principles: students in the completion condition completed backwards faded, worked-out examples of explanations; students in the problem solving condition wrote full explanations, thought to require means-end problem solving. The dependent variables …
