The Effect of WWW Document Structure on Students' Information Retrieval

Abstract

This experiment investigated the effect the structure of a WWW document has on the amount of information retained by a reader. Three structures common on the Internet were tested: one long page; a table of contents leading to individual sections; and short sections of text on separate pages with revision questions. Participants read information structured in one of these ways and were then tested on recall of that information. A further experiment investigated the effect that browsing moving between pages has on retrieval. There was no difference between the structures for overall amount of information retained. The single page version was best for recall of facts, while the short sections of text with revision questions led to the most accurate inferences from the material. Browsing on its own had no significant impact on information retrieval. Revision questions rather than structure per se were therefore the key factor.
