Previous studies of knowledge maps, however, focus more on the effects of knowledge maps on traditional learning than on e- learning. Knowledge maps have the advantages of simplifying the relational complexity of information and of structuralizing the information and knowledge. Using knowledge maps could help present e-learning materials in a more structure manner so that readers can easily digest the learning materials. It is important to study if the knowledge map-based materials design approach can improve a learner’s computer self-efficacy, learning performance and satisfaction level. 3 簡介

The research of O’Donnell et al. (O’Donnell, Dansereau, & Hall, 2002): 1. Learners recall more central ideas when they learn from a knowledge map than when they learn from text. 2. Learners with low verbal ability or low prior knowledge often benefit the most regarding measures of recall from the presentation of information in a knowledge map. 3. Learners who use knowledge maps as supports when interacting with peers cooperative learning environments learn more effectively. 4. Information presented in well-structured maps that are designed according to the gestalt principle is recalled better than when presented in less well-structured maps. 4 文獻探討

Chen and Shaw (2006) indicated that software tools and application programming are suitable for e-learning. Nickell and Pinto (1986) suggested that computer self-efficacy is positively associated with learning performance of SQL programming. Our research uses the core technology of SQL programming, ADO.NET, as the e-learning subject. 7 研究方法 ADO.NET browse-based e-learning materials

8 研究方法 ADO.NET knowledge map-based e-learning materials.

9 研究方法 知識地圖節點描述之定義

10 研究方法 ADO.NET 知識地圖式教材之操作設計說明

175 t hird year undergraduate students majoring in Management Information Systems. Have backgrounds in programming language. After the pre/post-test and learning activities  76 students in the experimental group (knowledge map-based)  76 students in the control group (browse-based). 11 研究方法

12 研究方法

學習評量鑑別度  Nunnally(1978) 的建議， KR20 的信度值要大於 0.7 ，因此將以試題刪除後成績作 為後續學習成績比較之基礎 13 分析實驗結果

Pre-test questionnaire  No significant difference between the understanding toward ADO.NET for both group (F1, 150 = 0.003, P = > 0.05). The reliability coefficients of Cronbach’s α in the post-test questionnaire.  computer self-efficacy & learning satisfaction 分析實驗結果

H1: Knowledge map-based e-learning materials design is more effective than browse-based one on learning performance(learning score & learning satisfaction). 15 分析實驗結果

H2: Knowledge map-based e-learning materials design is more effective than browse-based one on computer self-efficacy. 16 分析實驗結果

H3: Computer self-efficacy has a significant positive effect on learning performance(learning score & learning satisfaction). 17 分析實驗結果

Individuals can employ knowledge mapping when designing e- learning materials to improve the learning performance and satisfaction. if future e-learning materials can be constructed in knowledge maps, computer self-efficacy of learners can be increased, computer anxiety can be lowered and the sense of perceived ease of use can be improved indirectly. The improved computer self-efficacy for knowledge map-based group is even more significantly not only related to learning performance of ADO.NET programming, but also extent to improve the learning performance of other software applications 18 結論
