| Summary: | 碩士 === 國立臺南大學 === 數位學習科技學系教學碩士班 === 96 === This paper explores the ways to deploy concept map strategies to enhance children’s search strategy, improving their web search capability and further control information flow. A posttest was conducted on nonequivalent-groups with a 4 (concept map strategies) × 3 (natural science capability) factorial design. Sixty-three students participated in this experiment, and two independent variables are taken into consideration; that is, three different levels of knowledge and four concept map strategies. The experiment was conducted for five weeks. In addition to reading assignment, the experiment group has to learn different concept map strategies. The control group, on the contrary, takes only reading assignment.
The analysis was done via two-factor ANOVA, and a post hoc test was done based on various levels of each factor. The analysis results showed that no significant effect on classification ability by using different concept map strategies. However, significant difference was obtained for the students with medium and low caliber on data acquisition ability by using different concept map strategies. For the students with medium caliber, concept matching was most helpful for web browsing, while proposition identifying was the least. Thus, the instructor needs to be careful in designing their teaching strategies. For the students with low caliber, using proposition identifying is apparently poor.
For knowledge structure PFC index, there was significant difference for the students with medium and low caliber on PFC index by using different concept map strategies. For the medium students, concept-matching group achieved significantly better performance than the other groups in enhancing the knowledge structure. For the low caliber students, the performance of the concept-matching group was significantly better than the proposition-identifying group.
To sum up, concept matching is able to improve the web-searching ability for the sixth grade students with medium and low caliber in improving their knowledge structure. The outcome suggests that the instructors need to take into account the caliber of the students in selecting proper concept map strategies to improve their web-searching ability.
