摘要：The method of content development is one of the most important research topics in the area of e-learning. This paper assumes a method where visual content (text and still images) is presented in synchronization with sound content (narration) where a pointer makes the efficiency of resource allocation in cognitive memory capacity increase. It also makes the transmitted amount of information increase, based on the human cognitive-information-processing model called the dual channel model. We performed some control experiments (we measured the point of fixation for e-learning students with an eye mark recorder, memorization and content understanding tests, and a questionnaire) with or without a pointer under various content presentation environments of (1) narration, (2) text (with/without narration), (3) still images, (4) still images+text (with/without narration), (5) video, and (6) video+text} in e-learning. The results revealed that the pointer did not affect learners' acquisition of surface knowledge but did affect their acquisition of deep knowledge.
