The Role of Co-Regulated Learning during Students' Understanding of Complex Systems with Hypermedia.

Abstract

This study examined the role of different scaffolding instructional interventions in facilitating students' shift to more sophisticated mental models as indicated by both performance and process data. Undergraduate students (n=51) were randomly assigned to use of one of three scaffolding conditions (adaptive scaffolding (AS), fixed scaffolding (FS), and no scaffolding (NS))and were trained to use a hypermedia environment to learn about the circulatory system. Pretest, posttest, and verbal protocol data were collected. Findings reveal that the AS condition facilitated the shift in learners' mental models significantly more than did the comparison conditions. Participants in the AS condition regulated their learning by activating prior knowledge, monitoring their emerging understanding by using several strategies, and engaging in adaptive helpseeking. Learners in the FS and NS conditions were less effective at regulating their learning and exhibited great variability in self-regulation of their learning during the knowledge construction activity. AS participants also differed in the amount of time spend on each representation of information. An appendix describes the variables used to code the data. (Contains 4 tables and 64 references.)
