Effects of self-regulatory aids on autonomous study

摘要

The experiments described in this thesis tested whether encouraging the use of self-regulatory learning strategies enhances the effectiveness of autonomous study for novices in a learning domain. Previous research and theory have suggested that high-achieving students are proficient at self-regulating their learning, and they do so using a range of learning strategies for planning their study, monitoring the effectiveness of their efforts and elaborating their knowledge. Information processing theories of instructional design suggest that learning is optimal when working memory load is managed effectively. Accordingly, methods have been devised for reducing load associated with unnecessary task requirements, as well as dedicating additional capacity to the construction and automation of knowledge schemas. Less is known, however, about instructional methods for encouraging self-regulatory learning strategies. Experiments 1, 2 and 4 examined the effect of encouraging participants to reflect on their understanding of topics they had been taught previously. Although these participants were able to accurately estimate their level of understanding in some situations, they failed to consistently use this knowledge to guide their study of topics they had previously understood poorly. In light of this finding, Experiments 3 and 5 examined the effect of encouraging participants to plan a free study period, with the direction to prioritise the topics that they had understood the least well. This intervention had a modest positive effect on post-test performance. Experiment 6 examined the effect of encouraging two elaborative strategies, namely explanation generation and summarisation. The former benefited performance, whereas the effectiveness of the latter depended on the comprehensiveness of the summaries produced by the participants. Finally, Experiment 7 examined the effect of providing broad-spectrum instruction in learning strategies, with minimal requirements to engage in specific strategies. This intervention resulted in an overall benefit to performance. Overall, the results of this dissertation suggest that certain instructional aids for self-regulation yield benefits to the autonomous study by domain novices without overburdening working memory.
