초록
The purpose of this study was to examine the effects of learning strategies, metacognition, working memory on achievement in the hypertext learning environment and also to review what the most influential variables is in the hypertext learning. The subjects were 92 sixth graders. They were assigned to either experimental groups (text-strategy group, hypertext-strategy group) and control groups (text-strategy control group, hypertext-strategy control group). The experimental groups performed a learning strategy to reduce cognitive load. In contrast, the control groups did not make use of a learning strategy. The results were as follows: As expected, the experimental groups significantly outperformed the control groups. The high metacognitive regulation group achieved higher scores than its low counterpart. However, there appeared to be no significant differences on the level of metacognitive knowledge. As the level of working memory span, the central executive span affected achievement. However, the phonological loop and visuo-spatial working memory span didn't significantly affect achievement. The results of study demostrate that metacognitive regulation and central executive are influential variables that can be used to help achievement in hypertext. The findings suggest that metacognition and working memory should be taken into consideration in hypertext instructional design in order to reduce extraneous cognitive load and increase germane cognitive load.
