The effects of ability and prior knowledge on recall in social studies /

This research examined the influence of ability, prior knowledge and knowledge of text structure on expository history text corpora comprehension using a quasi-representative research paradigm. Sixty grade eight students participated in two history units. Hypotheses that ability, prior knowledge and knowledge of text structure would significantly influence performance in terms of the amount and organization of information presented on various measures were supported for the Ancient Man unit only. No interactions between the independent variables arose. The lack of significant findings for the Ancient Egypt unit is explained by poor text corpus organization and weak text structure. The findings suggest that teachers can facilitate students' comprehension of an expository text corpus by providing appropriate background knowledge of content and strategies for recognizing and utilizing text structure. Further, teachers should consider the organization of a textbook or corpus, and when necessary manipulate the materials to improve their structure and comprehensibility
