摘要
面對資訊爆炸與十倍速變動的時代，相對而來的便是知識的恐慌，經營典範的轉移、應用技術的更新，「學習」儼然已經成為因應變動最佳的管道。網際網路的便利性與多元化讓我們可以快速共享資訊，而許多的在網路上的網站也都陸續提供各式各樣的教材內容，使得另一波新興的網路學習管道與模式已經成形。非同步網路教學模式的出現，讓使用者不受時間與地點的限制，隨時可上網學習獲取新知，而網路教學的價值在於充分的發揮了學習無國界（Learning Anywhere）與學習無時限（Learning Anytime）的優勢。然而我們發現目前的教學網站仍然存在著許多的不足，許多網站更只有傳播資訊的功能，而沒有傳播學習的效果。在本論文中，我們提出了一個具備完整影音多媒體學習模式的系統架構，並結合教務資料倉儲的建置，此系統可以透過Web方式即時展現學習成績的各項統計分析，讓學生與教師之間的互動除了可以透過Web達成之外，還能立即獲得整體成績與相關資料的分析結果，讓學習者的學習環境與需求能產生教育學中的不同學習模式，以求在最短時間達成最大學習效果的目標。這也將是二十一世紀教育的主流模式—以學員需求為中心，個人化、自主式的學習方式。拜網路科技一日千里之賜，終身學習的理想將因網路教學機制的成熟而成為可能。上網選擇自己屬意的課程與喜歡的老師來學習，這樣的學習機會在網路上可以是一年365天，一天24小時隨時垂手可得的。我們的網路學習環境是一個雙向溝通的管道，因此老師與學生、學生與學生間可以透過電子郵件、網路論壇、網路留言板，甚至即時性的網路會議來彼此討論，交換心得。最後透過本系統之資料倉儲、OLAP線上資料分析、Exchange知識管理與學習評量的功能，教師、學生甚至是校長均可依不同的維度來觀察學生們在各方面的學習趨勢，進一步的調整教材的製作、題庫的編排、教學的方式等等，讓師生的關係、學習的效率均能達到最佳化的理想境界並實踐終身學習的目標。

Abstract
As lifelong learning and
Web-based education begin to emerge and proliferate, the need for standardizing
educational materials becomes increasingly important. Web is an efficient way
for scholars and scientists to pool knowledge and share information. Since
distance learning is a very important approach for future education, many
researchers have established sites on the Web and referred to them as network courses. This is increasingly
popular at present, with an ever-increasing number of these courses cropping up
everywhere in the cyberspace. However, most of these courses provide little in
the way of interaction for instructors and learners. Those developing courses
on the Web often seem to be confused about the difference between delivering information and delivering learning.
In this paper, we propose
a framework and develop a Web site, based on the concept of Web-centric
integrated distributed learning environments. Incorporating the application of
professional pedagogical principles of learning/education and appropriate
instructional design, such learning environment can support extremely high
quality, student-centered education program for remote learners. It makes extensive
use of the synchronous and asynchronous tools available for Web-based
communications. Distant learners may use any Web browser to engage in
collaborative online activities.
Another focus of our study
is to establish an academic data warehouse to help instructors and students to
assess their own thinking for clarity, accuracy, precision, relevance, depth,
breadth, and logic related to the dedicated course. The system will incorporate
placement evaluation, formative evaluation, summative evaluation, and
diagnostic evaluation to improve the learning quality. Furthermore, student
records can be analyzed by OLAP techniques and presented on Web, which help the
learners, teachers, and school administrators to visualize various aspects
regarding students’ learning effect.
