Designing efficient text presentation of multimedia CAI — the evaluation of dynamic text patterns and the negative repetition effect on memory
Computers & Education Volume 37, Number 2, ISSN 0360-1315 Publisher: Elsevier Ltd
The present study investigated the effects of presenting the same material with dynamic text patterns in multimedia CAI. Four commonly used dynamic text patterns were utilized to present 10 basic concepts of mechanics. Two hundred college students selected at random from two universities were randomly assigned to one of 10 experimental conditions created by combining five text patterns (i.e. four dynamic patterns and a static presentation) and two types of repetition conditions (i.e. text presented once or three times). Their working memory capacity was assessed via a reading span test to ensure that the subjects were able to process and retain information at about the same level. Differences were found on the affective and perceptual evaluation of the dynamic text pattern. After partialing out the effect of working memory capacity, we found that, on the memory test, participants performed worse in conditions where learning material was presented three times. Interpretations and implications in designing CAI are discussed.
