The Effects of Graphical Overviews on Knowledge Acquisition in Hypertext.
Peer reviewed Peer reviewed
de Jong, Ton; van der Hulst, A. – Journal of Computer Assisted Learning, 2002
Describes a study of undergraduates that enhanced a hypertext environment with a graphical overview that represented the basic domain structure and designed the layout so learners were unobtrusively encouraged to follow a sequence of exploration that followed the domain structure. Results indicated that a visual display conveys knowledge in its…

Learning in the Middle School Earth Science Classroom: Students Conceptually Integrate New Knowledge Using Intelligent Laserdiscs.
PDF on ERIC Download full text
Freitag, Patricia K.; Abegg, Gerald L. – 1991
A study was designed to describe how middle school students select, link, and determine relationships between textual and visual information. Fourteen authoring groups were formed from both eighth-grade earth science classes of one veteran teacher in one school. Each group was challenged to produce an informative interactive laservideodisc project…
