摘要

知識經濟時代強調知識的重要性，也使得知識分享與學習的角色更受社會的重視，隨著資訊科技發展及網際網路的日益普遍，數位學習已成為新興學習模式之ㄧ，透過數位學習，不僅可提高知識的分享性與再利用性，還可突破時間與空間的限制，進行遠距離與非同步的學習。本研究主要探討如何透過適性化與動態規劃學習的內容來提昇數位學習之成效，且強調以人類知識建構與發展為基礎之概念學習，經由領域本體論（Domain ontology）之建立，輔助提供符合學習者之學習內容與呈現方式，並採用動態規劃學習內容演算法進行學習地圖規劃與最佳化調整，使學習者可以在有限的時間內得到較大的效益，並且減少學習上的迷失與認知負載。本研究發展一以本體論為基之適性化動態概念學習機制，主要研究項目包括：（１）以適性化、數位學習與學習理論為基礎，設計一適性化動態概念學習模式、（２）考慮適性化的需求設計Learner model、分析知識的形態設計Knowledge map、（３）針對演算法與呈現方式設計Learning map、（４）由適性化動態概念，進行學習地圖規劃演算法的設計。

Abstract

As the value of knowledge has been recognized, the importance of knowledge sharing and learning has attracted more and more attention in the age of knowledge economy. With the rapid development of information technology and internet, E-learning has become one of the promising learning models. Applying e-learning, we can not only improve knowledge sharing and reusing but also break through the restrictions of time and space, go on long distance and asynchronous learning. This thesis aims to promote the effectiveness of e-learning through adaptive and dynamic learning based on concept learning for human knowledge development. A domain ontology is developed as a basis to provide adaptive content and presentation to learners. In addition, a dynamic planning algorithm is proposed to adjust learning map to help learners achieve learning goals in limited time without getting lost in overwhelming knowledge and cognitive over loading. The objective of this thesis is to develop an ontology-based adaptive and dynamic concept learning mechanism so as to promote the effectiveness of e-learning. The objective can be obtained by：(1) designing an adaptive and dynamic concept learning model based on theories of adaptive learning and e-learning; (2) designing a learner model according to individual’s adaptive requirements; (3) designing a knowledge map through knowledge analyzing; (4) developing a learning map in consideration of content presentation; and (5) designing an adaptive and dynamic concept learning map planning algorithm to plan and adjust learning map.
