Effects of content representation and readers' prior knowledge on the comprehension of hypertext
نویسندگان
چکیده
This study investigated the role of various types of content representation devices on the comprehension of an expository hypertext. We hypothesized that hierarchical representations, but not network representations, may help low prior knowledge students organize their representation of the text contents. Forty-seven students with low or high prior knowledge in Social Psychology were asked to read a hypertext using one of three content representations: a hierarchical map, a network map and an alphabetic list. Then, the participants performed a multiple choice comprehension task, a summary task and a concept map drawing task. The hierarchical map improved comprehension for the low knowledge participants at the global, but not at the local level. There was no effect of content representation on the comprehension of high prior knowledge students. We discuss the implications of these results for a theory of the comprehension processes involved in reading hypertext. r 2003 Elsevier Science Ltd. All rights reserved.

In two experiments we identified two main strategies followed by hypertext readers in order to select their reading order, the first consisted in selecting the text semantically related to the previously read section (coherence strategy) and the second in choosing the most interesting text delaying less interesting sections (interest strategy). Comprehension data revealed that these strategies ...

متن کاملThe Effect of Reading Strategies and Prior Knowledge on Cognitive Load and Learning with Hypertext
Reading strategies, prior knowledge and cognitive load are some variables that have been related with comprehension and learning with hypertext systems. In this study we analyze the effect of two different hypertext reading strategies – coherence and interest – and two prior knowledge levels – low and high on cognitive load, and their relation with learning. For low prior knowledge readers, dat...

The literature on assessing the cognitive processes involved in hypertext comprehension during the last fifteen years has yielded contradictory results. In this paper we explored a possible factor affecting this situation, mainly the potential effects on comprehension of reading strategies in hypertext. In experiment 1, results showed that reading strategies affect selectively the textbase and ...
