摘要

本研究旨在探討超文件電腦教材與傳統印刷教材，在高三化學「原子結構與週期表」單元上之學習成效差異。
首先依據超文件相關學習理論的規劃，與「原子結構」相關概念之學習建議，開發完成「原子結構與週期表」超文系統。為評估本超文系統之學習成效，以台中縣某私立中學的175名高三學生為研究樣本，進行前測、學習活動及後測，並施以問卷調查瞭解使用者對本系統的看法。
前測結果顯示，在教學實驗前，使用本超文系統與使用傳統印刷教材的兩組學生，所擁有的先備知識並無顯著差異；並依據前測結果將學生分為高、中、低先備知識。後測結果顯示，兩組之學習成效並無顯著差異。依不同先備知識分析後測結果，顯示只有高先備知識的學生在使用本超文系統的成績顯著優於使用傳統印刷教材。推測高先備知識的學生較能夠整合超文系統的知識，而從中得到較高的學習助益。
從後測作答結果中發現，大量的圖片教學，雖可以提昇學生的學習興趣，但如氫原子模型、游離能等抽象概念，學生依然存有迷失概念。另外，在問卷調查方面，使用者對本系統多持肯定的態度，但也建議在互動性與畫面設計部分再做改進。

The main purpose of this study aims at evaluating the effectiveness of the web-based chemistry teaching materials in the chapter of “The Atom Structure and the Periodic Table”. Some differences between web-based material and traditional textbook are discussed in this research.
The development the hypertext courseware was based on the scheme of the instructional hypertext and the suggestions on the “The Atom Structure and the Periodic Table”. Empirical research was carried out in order to evaluate its effectiveness. 175 private senior high school students were selected by purposeful sampling, and joined the pre-test, self-study on the chapter and post-test. In addition, the students who studied the hypertext courseware were questionnaire their opinions about the software.
The result of the pre-test showed that the controlled group and the experimental group didn’t have significantly outperformances with each other. Otherwise, the students' prior knowledge level was classified according to the pre-test. The result of the post-test indicated that the students who study the hypertext courseware didn’t outperformed those who study the lecture text significantly. Only the students of high prior knowledge made significantly outperformance in the hypertext courseware than in the lecture text. The empirical research result suggested that students with higher prior knowledge get high benefits in the hypertext courseware.
The large amount of pictures in hypertext courseware could raise the interesting in learning this chapter. However, some misconceptions such as “ H atom structure” and “Ionization energy” still rooted in students. In addition, the questionnaires revealed that the students who study the hypertext courseware responded positively to the program and considered it a great deal aid in learning this lesson. However, they suggested more efforts should be made to increase the interaction and in the perfection of the appearance design.
