Popis
Shrnutí:Techniques to aid the manipulation of a computer based document were tested by a group of 38 novice users. The subjects were given a period of time to browse the document, and were subsequently given a set of goal related tasks in a question/answer session. The techniques tested were sequential paging, index referral, text find and embedded hypertext links. 3 differing types of link mechanisms were assessed and compared with each other. Sequential paging and index referral were the most commonly used of the techniques. Text find was employed more for goal related tasks than for browsing. The hypertext link technique was generally unpopular, especially for goal related tasks. In order to establish the importance of the text find technique, the effect on reading strategies without this facility was also investigated. For browsing operations, an increase in paging and a decrease in hypertext linking was observed. In the case of goal directed searching, an increase was observed in paging and index referral techniques. The study calls into question the usefulness of hypertext in educational software. Original abstract-amended.
