웹 기반 학습에서 텍스트형,아이콘형,메타포형 인터페이스가 학습수행에 미치는 영향 = The Effects of a Text, an Icon, and a Metaphor based Interface on Learning Performance in Web-based Learning

다국어 초록 (Multilingual Abstract)

This study aims at finding out how interfaces such as a text type, an icon type, and a metaphor type influence students on their learning performances in Web Based Learning. Detailed research problems are as follows: 1. Is there any differences on navigation path according In the types of interfaces (tex in-terface, icon interface, metaphor interface)? 2. Is there any differences on the academic attainments according In the types of interfaces(text interface, icon interface, metaphor interface)? In order to solve these problems of study, one hundred twenty students out of three classes who were in the six grade, of CheongJu elementary schhool were selected as sub- jects for this study. Learning assignment for this study was ``water pollution`` from ``environment rollution`` and ``nature preservation`` for six graders in the elementary school. Three programs of which contents are the same but the types are different were written in Jamba 2.1 which is a web authoring tool Collected data were analyzed with SPSSWIN package through the application of One-way ANOV A. The results from this study were as follows: 1. Total number of nodes each group studied are different(p<.05). The number for the icon interface`` group was the highest, next was the text interface``s group, and the metaphor interlace`` group had the lowest. 2. The frequency of access to the reference node was different by the three group:;(p<. 05). The iron interface``s group had the lowest, next was the text interface`` group, and the metaphor interface`` group had the highest 3. The academic attainments were different by the three groups(p<.05). The text inter-face`` group had the highest points on average of the academic attinments. Next was the metaphor interface``s group. The icon interface`` group had the lowest. Conclusions drawn from these results are as follows: First, the interlace type. could reasonably influence both on navigation path and on the attainments. The group used the text interface program had no trouble in accessing to in-formation they needed as well as in learning through it. Also, they had higher academic at-tainments. The group who used the icon interface program went through various and many nodes, but they had lower academic attainments due to misunderstanding the meaning of the icon. The group who used the metaphor interface program got a higher point in relation with the questions of the reference node than the group who used the .icon interface program did because they knew the meaning of the button clicked, though at first they didn``t go through many nodes because it took many hours for them to understand the meaning of the figure. Second, it is hard to say that the quantity of information gotten through the navigation on the program had a direct influence on the academic attainments, but it is possible to insist that the quantity of information from the time when learners exactly know the meaning of the icon or the button has a positive influence on the academic attainments. Third, interface design which is used for the sense of beauty makes the students get confused. This means that presenting as a text is better than the metaphor unless presented with the clear understandable image for the students.
