The Influence of Self-Regulated Learning and Prior Knowledge on Knowledge Acquisition in Computer-Based Learning Environments
Bernacki, Matthew
ProQuest LLC, Ph.D. Dissertation, Temple University
This study examined how learners construct textbase and situation model knowledge in hypertext computer-based learning environments (CBLEs) and documented the influence of specific self-regulated learning (SRL) tactics, prior knowledge, and characteristics of the learner on posttest knowledge scores from exposure to a hypertext. A sample of 160 undergraduate education majors completed measures of prior knowledge, goal orientation, intrinsic motivation, self-efficacy to self-regulate learning, and a demographic survey. They were trained in the use of nStudy, a learning environment designed to facilitate self-regulated learning from web-based media including hypertext and to trace learners' actions while they learned online. Learners completed a 20-minute study session learning about Attention Deficit Hyperactivity Disorder and a posttest to assess changes in knowledge scores. Results indicate that employment of individual SRL tactics including tendency to highlight was found to be associated with increased posttest knowledge scores across learners. Goal orientation and prior knowledge also significantly predicted posttest knowledge scores in regression models. These findings can be used to inform the design and use of hypertext in order to individualize computer-based instruction and maximize knowledge acquisition for students, based upon their individual characteristics.
