Computer-based learning environments (CBLEs) present important opportunities for fostering learning; however, studies have shown that students have difficulty when learning with these environments. Research has identified that students' self-regulatory learning (SRL) processes may mediate the hypothesized positive relations between CBLEs and academic performance. In this review, we identified 33 empirical studies of SRL and CBLEs. We address three research questions: (1) How do learner and task characteristics relate to students' SRL with CBLEs? (2) Can various learning supports or conditions enhance the quality of students' SRL as they learn with CBLEs? (3) What conceptual, theoretical, and methodological issues exist for this growing area of research? We found evidence that specific SRL processes are more often associated with academic success than others and that SRL skills can be supported. We also identified a number of issues that researchers should aim to address in future investigations, including a more comprehensive measurement of facets of SRL and the quality of SRL processes, the seeming disconnect between SRL processes and learning outcomes, and the distinction between self-and other-regulation.
This study examines the effectiveness of three scaffolding conditions on adolescents' learning about the circulatory system with a hypermedia learning environment. One hundred and eleven adolescents (n=111) were randomly assigned to one of three scaffolding conditions (adaptive scaffolding (AS), fixed scaffolding (FS), or no scaffolding (NS)) and were trained to use a hypermedia environment to learn about the circulatory system. Pretest and posttest data were collected to measure the qualitative changes in students' mental models of the topic and quantitative changes in their declarative knowledge. Verbal protocols were collected during the 40-minute learning task to examine how each condition affected the way in which students regulated their learning. Findings revealed that learners in both the AS and NS conditions gained significantly more declarative knowledge than did those in the FS condition. Also, the AS condition was associated with shift in learners' mental models significantly more than the other conditions. Associated with these significant shifts in their mental models, learners in the AS condition regulated their learning by planning and activating prior knowledge, monitoring their cognitive activities and their progress toward learning goals, using several effective strategies, and engaging in adaptive help-seeking. By contrast, those in the NS condition used fewer effective strategies, while those in the FS regulated their learning by using several regulatory processes which seemed to impede their learning. Implications for the design of scaffolds for fostering students' self-regulated learning with hypermedia are presented.
We examined how self-regulated learning (SRL) and externally-facilitated selfregulated learning (ERL) differentially affected adolescents' learning about the circulatory system while using hypermedia. A total of 128 middle-school and high school students with little prior knowledge of the topic were randomly assigned to either the SRL or ERL condition. Learners in the SRL condition regulated their own learning, while learners in the ERL condition had access to a human tutor who facilitated their self-regulated learning. We converged product (pretest-posttest shifts in students' mental models and declarative knowledge measures) with process (think-aloud protocols) data to examine the effectiveness of self-versus externally-facilitated regulated learning. Findings revealed that learners in the ERL condition gained statistically significantly more declarative knowledge and that a greater number of participants in this condition displayed a more advanced mental model on the posttest. Verbal protocol data indicated that learners in the ERL condition regulated their learning by activating prior knowledge, engaging in several monitoring activities, deploying several effective strategies, and engaging in adaptive helpseeking. By contrast, learners in the SRL condition used ineffective strategies and engaged in fewer monitoring activities. Based on these findings, we present design principles for adaptive hypermedia learning environments, engineered to foster students' self-regulated learning about complex and challenging science topics.
Sixty-two high-school biology students, paired heterogeneously based on prior knowledge, learned about genetic using GenScope, a computer-based learning environment (CBLE), over four 90-minute class periods. Differences between low and high prior knowledge students emerged with convergence of verbal process data and pre-and post-test product data. The low prior knowledge students gained significantly in conceptual understanding from pre-to post-test, whereas the high prior knowledge students' understanding did not significantly change. In an analysis of their verbalizations, low prior knowledge students regulated their learning by relying on their partners for cognitive and other regulatory support whereas the high prior knowledge students spent most of their time regulating their own learning or providing external support for their lower prior knowledge peer. The results of this naturalistic study can potentially be used to inform educational practice by highlighting scaffolds that may foster self-regulated learning in a CBLEmediated science inquiry context.
