摘要：

This study designed tow experiments to explore the effect of two presentation forms(liner presentation and concept-map navigation presentation)on the student's learning process. Using the method of protocal analysis and the learning path records of these students, the author of this paper further analysed the information-processing process of these students. The main results showed as follows: (1) In the initial study phase, the main effects of both the presentation form and the learner type were obvious, and the interaction effect of these two variables was also obvious. Contrasting with the liner presentation form, the concept map navigation form interfered with the learning process of the student, especially the learning-disabled students. (2) There was a significant difference between excellent students and learning-disabled learning-disabled on self explanations amount. Excellent students produced more self- explanations than learning-disabled students, especially on two phases of learning from the the example and the conclusion. (3) Under the same learning path, the main effect of the learner type variable was obvious, the main effect of the presentation form and interaction effect of these two variables weren't obvious. But the liner presentation grouped still acquired a better result than the concept-map navigation presentation groupe.
