| Abstract: | College students with either high or low prior domain knowledge (PK) read a text chapter presented in short pages on a computer monitor. Half of the participants read with headings present and half with headings absent. The computer recorded time spent reading and rereading each short page. Learning was assessed through a structured recall task. In general, headings seem to improve recall of high importance information, and headings were more effective for high PK learners. Analysis of time data showed that participants with headings spent more time per word reading the pages with headings than participants that did not have headings. Prior knowledge had no effect on attention to either high importance information or important supporting detail. Low prior knowledge readers decreased the amount of time spent reading each word as they progressed through the passage and neither the presence nor absence of headings influenced this effect. |
