摘 要：In order to study the benefits of metacognition with OCTAL, we authored a concept map and question set for topics from UC Berkeley's CS10: The Beauty and Joy of Computing. We presented the tool to the students of the course between their first and second midterm exams during the spring of 2014. In the study, we found no statistically significant changes in metacognition among participants who used the tool. However, analysis of participant usage of the tool reveals differences in the way learners approach concepts presented to them in a list versus in a graph. In particular, while users often followed a list of concepts in-order, learners that navigated a graph explored concepts in clusters.
