Cognitive Load Reduction on Multimedia E-Learning Materials

In e-learning area, the content development method is one of the most important research topics. This paper proposes a presentation method of visual contents (a text, a still image) in synchronization with narration (sound content) and a pointer to make the efficiency of the resource allocation of cognitive memory capacity increase, and make the transmitted amount of information maximize, based on a human\´s cognitive-information-processing model "dual channel model." Under various contents presentation environment {(1)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 the validity of this model and the effectiveness of the proposed content development method in e-learning.
