The Effect Of Leads On Cognitive Load And Learning In A Conceptually Rich Hypertext Environment, Pavlo D. Antonenko Jan 2007

The Effect Of Leads On Cognitive Load And Learning In A Conceptually Rich Hypertext Environment, Pavlo D. Antonenko

Retrospective Theses and Dissertations

The purpose of this experiment was to determine whether leads affect cognitive load and learning from conceptually rich hypertext. Measures of cognitive load included self-report of mental effort, reading time, and event-related desynchronization percentage of alpha, beta, and theta brain wave rhythms. Conceptual and structural knowledge tests, as well as a recall measure were used to determine learning performance. Measures of learners' reading ability, prior knowledge, and metacognitive awareness were employed to establish the effect of individual differences on cognitive load and learning from traditional and lead-augmented hypertext. Results demonstrated that while leads appeared to reduce brain wave activity associated ...
