Abstract

In e-learning area, the content development method is one of the most important research topics. This paper assumes a presentation method of visual contents (a text, a still image) in synchronization with sound content (narration) and a pointer to make the efficiency of the resource allocation of cognitive memory capacity increase, and make the transmitted amount of information increase, based on a human's cognitive-information-processing model "Dual Channel Model." Under various contents presentation environment {(l)Narration, (2)Text (with narration / without narration), (3)Still images, (4)Still images + text (with narration / without narration), (5)Video, and (6)Video + text} in e-learning, we performed some control experiments (measure the point of fixation for e-learning students by an eye mark recorder, memorization and a contents understanding test and the questionnaire) with or without pointer. The results showed that the pointer does not affect learners' surface knowledge acquisition but affects learners' deep knowledge acquisition.
