Knowledge Point Based Curriculum Developing and Learning Object Reusing

Abstract

In an E-Learning environment, learning contents are usually organized through a series of courses, and the concrete learning contents are explained through various learning resources. With the development of E-Learning systems and the passing of time, courses and learning resources will update, develop, and change inevitably. Because, in a discipline, the knowledge body can be divided into a series of knowledge points, so we proposed and designed a discipline oriented common knowledge ontology base (KOB) to organize and store all the knowledge points and their relations in a discipline. On the basis of KOB, we proposed a knowledge point based course developing model and a learning object metadata model. Through KOB, the knowledge points can be reused in different courses, so to improve the efficiency in courses developing, course contents authoring and contents updating. Furthermore, when a new learning object is registered to an E-Learning system or a learning object updated, through knowledge points mapping between courses and learning objects, it will be automatically reflected in according courses that have the same knowledge points with the learning object. So, on the basis of KOB, the work of courses developing and learning resources management becomes easier and flexible.
