The aim of this study was to examine the effects of structure and navigation aids on students' learning from hypertexts. Participants were 48 undergraduate students. Group 1 (N = 24) read 2 hypertexts (one network, one hierarchical) with high navigation support (a graphical overview, a coherent links list, and use of different colours for visited…

This study investigates how graphical and content list type overviews with and without navigation restrictions affect the cognitive load experienced by a learner searching for information in a hypertext. The study used a 2x2 between factor design with the factors navigability (restricted vs. non-restricted) and overview format (graphical vs.…

This study contributes to research investigating the effects of individual differences and online instructional design on learning. Learning performance was compared across three hypertext formats incorporating different navigational aids. The hierarchical map represented the physical structure of the hypertext in one condition, while the network…
