本体理论及其在E-Learning中的应用

E-learning是信息时代的产物,是学习形式、学习手段和学习方法的革命.但是,E-learning面临一个重大挑战,即如何表示教学内容的丰富语义.根据现代认知心理学理论,从教育教学规律出发,提出一种教学领域本体的构建方法.借助该方法,设计和建立了C类程序设计课程领域本体.实践证明它能满足用户自适应学习的需求,降低教师的教学难度和学生的学习难度.构建的领域本体对“C程序设计”和“C++程序设计”这两门课程知识组织结构形成了共同理解与认识,为进一步建立支持个性化语义检索的课程资源网络系统奠定了基础.

THEORY OF ONTOLOGY AND ITS APPLICATION IN E-LEARNING

E-learning is a product of the information age.It is the form of learning,the means of learning,and the revolution in learning approach.However,E-learning faces a major challenge:how to represent rich semantics of teaching content.According to the modern cognitive psychology theories and proceeding from the education teaching rule,we set up a construction method of teaching domain ontology.With this method,the Class C programming course domain ontology is designed and built.Practice shows,it can meet the needs of user self-adaptive learning,reduce the difficulties of teachers in teaching and of students in learning.The domain ontology built forms common comprehension and cognition on the knowledge organisation structures of two subjects "C programming" and "C++ programming",which lays a foundation for further establishing the course resources network system supporting the personalised semantic retrieval.
