The influence of screen size and text layout on the study of text

Abstract

Abstract This study investigates the effects of screen size (12 inch versus 15 inch) and text layout (well structured and ill structured) on the learning of text presented on the monitor of a personal computer. Two aspects of learning are assessed. A summary and a multiple-choice test are employed to measure the amount of information retained. Efficacy of learning is assessed by learning time and by cognitive effort, as measured by the performance on a secondary task. The results indicate that neither screen size nor text layout has a significant influence on the required cognitive effort or on the amount of information acquired. There is, however, a significant (main) effect of screen size on learning time: subjects using a 15 inch screen need less learning time than subjects using a 12 inch screen, with no difference in learning performance. It is suggested that more efficient integration processes in constructing the semantic representation are responsible for this reduction in learning time. Implicati...
