PhD Dissertation title: The effect of leads on cognitive load and learning in a conceptually rich hypertext environment

PhD Advisor: Ann Thompson and Dale Niederhauser

Area of PhD research: The purpose of this study was to determine the effect of leads (link comments) on cognitive load and learning in a conceptually rich hypertext environment. Assessment of the effect of leads was approached through measurement of cognitive load and learning performance. Subjective and objective methods, including self-reported mental effort, reading time, and electroencephalogram, were employed to measure cognitive load. Subjects' learning performance was assessed using measures of recall, conceptual, and structural knowledge. Results suggest that leads are a potentially useful tool for supporting learning and reducing ineffective cognitive load associated with split attention. Leads may help educators circumvent working memory limitations, and better align presentation of information in hypertext with human cognitive architecture, which will ultimately enhance learning from hypertext-based instructional materials.
