摘要

學習路徑原是簡單的問題，亦即在預設的學習目標下，安排循序的課程內容供學生學習。然而在數位學習環境中，具有相同學習目標但不同教材的情況普遍可見，例如將「一綱多本」的教材內容合編為學習路徑，則是一項複雜的問題。探究其困難有二：(1)各教材的內容編輯並不一致；(2)缺乏上層的學習路徑指引供各教材遵循。再者，當加入新課程的學習路徑或新的教材時，將使得問題的複雜性持續存在。因此，資料導向的系統設計無助於解決問題，知識導向設計則將問題抽象及模型化，有利於解決此類問題。本研究利用知識本體(Ontology)，將學習路徑與教材分別建模為概念架構，分析各概念的必要屬性，再利用語意規則處理實例之間的隱含關係，二者共構為抽象型式的知識庫。當事實知識依概念架構給予時，可利用推論機制獲得更完整的知識庫內容。最後，使用者以個人的情況為查詢條件，數位學習系統即可規劃出個人化的學習路徑。本研究以國內的「九年一貫課程」為例，說明知識庫的建置及實證經驗。結果顯示，由知識本體與語意規則共構的知識庫，確可解決安排個人化學習路徑的問題。另外，這項設計也改善知識庫的後續維護，增加知識庫的可信賴度。

Curriculum content sequencing is about managing a learning route to help users reaching a learning goal. A conventional learning route consists of ordered contents mostly made by using a single teaching material. In an e-learning system, amount of teaching materials are resemble. Similar contents can substitute mutually for making a flexible learning route. Since the inconsistency exists in materials editing and cataloging, composing these contents from multiple sources leads the sequencing complexity. However, most e-learning systems lack sequencing knowledge to guide participants how a sequence is composing. This study utilizes a knowledge intensive approach to model content sequencing and course materials into ontological concepts. The semantic rules are used to describe relationships between instances. The facts such as a specific curriculum sequence and teaching materials are regarded as asserted knowledge to complete the knowledge base. An example of math course in compulsory education is developed by using Web ontology Language (OWL) and Semantic Web Rule Language (SWRL). Empirical lessons show: (1) the ontology and semantic rules address content sequencing by modeling general and abstract views that can be reused by other similar curriculums; and (2) the knowledge stakeholders are responsible to maintain the knowledge base that leads the content sequencing guidance system reliable and durable.
