摘要

由於現今的電腦設備普及與網際網路興起，學習者的學習型態也隨之轉變。
學習者己經不再是一個課堂中的訊息接受者。透過網路的連接，學習者可以依自
己的興趣、喜愛，選擇自己想要學習的內容，以達到適性學習的目的。其中，學
習網站是目前很重要的應用之一。然而，目前研究有關於學習型網站的開發與設
計，可用性設計的因素是顯少被探討的議題。有部分研究探討可用性介面學習型
網站的研究往往只有針對單一類型的網站，所以無法對整體學習型網站歸納出共
同的可用性問題。因此，本研究將對於三個不同類型的學習網站進行可用性評估，
以探討此一不足。此三類個別分別為LiveABC 一般學習網站、我的寵物遊戲式
網站與合作式概念構圖合作式學習網站。除此之外，在評估工具方面，本研究將
採用評估、可用性問卷與訪問調查。根據評估與調查結果發現Neilson heuristics
方法對於評估學習網站介面會產生可用性方針的差異性，其主要包括以下四個面
向：自由度(H3) VS. 靈活性與操作效率(H7)、符合真實的世界(H2) VS.一致性
(H4)、能見度(H1) VS.簡約設計(H8)與學習流程V.S 操作流程。因此，本研究希
望可以對未來學習網站的開發者提供一個可用性介面的參考依據。最後，本研究
針對學習網站的可用性介面歸納出三項結論：學習網站的效能及易用性有待提升、
學習網站可以增進學習課程的效率與降低學習者對於使用學習網站的顧慮。

A growing population of using personal computers and the Internet
has made a dramatic change on learners’ behaviors. Learners could have
multiple options to decide what they want to learn through the Internet.
Therefore, a variety of Web-based learning systems (WBLSs) have
mushroomed. However, the usability of Web-based learning systems are
rarely discussed. Current studies mainly focused on single type of
WBLSs. In other words, there is a need to give a series of overall
usability guidelines for the interface design of various types of WBLSs.
To address this issue, this study aimed to carry out a number of usability
assessment on three different types of WBLSs: LiveABC, My-Pet and
Collaborative Concept Map System. Furthermore, the assessment of
Neilson heuristics, usability questionnaire and interview were used in this
study. In brief, results are mainly demonstrated in four aspects: (1) user
control and freedom (H3) vs. flexibility and efficiency of use (H7), (2)
match between system and the real world (H2) vs. consistency and
standards (H4), (3) visibility of system status (H1) vs. aesthetic and
minimalist design (H8), and (4) learning processes vs. operating
processes. Finally, this study proposed a set of usability guidelines for
designers to develop future WBLSs. In conclusion, three viewpoints are
drawn. First, there is still a room for improving the effectiveness of
WBLSs, as well as how to make WBLSs easy to use. Second, WBLSs
iv
have the potential to increase the efficiency of learning. Finally, there is a
need to take into account learners’ concerns.
