| With the development of Internet technology, network education becomes a new direction of development of education at home and abroad, which receives more and more attentions and which accelerated by e-learning. As the most active organization that is responsible for e-learning standardization, IMS establishs lots of specifications. IMS's learning design Specification gives a description method, which describes the learning objective which learner can gain by executing some learning activities orderly in the learning environment. Learning objective is the key element of learning design, and it is the provision or assumption which made by learner to meet the standards or requirements of learning activities. Learners can make up learning objective to search learning resources to meet the conditions of learning activities.This paper described the learning objective with the logic language as a formal language, and applied into the domain ontology. Includes following outcomes:Firstly, after the study on ontology and domain ontology, constructed key domain knowledge ontology of computer network course.Secondly, after the analysis of the feature and functionality of pedagogical objective, and by studing the classification and writing patterns of pedagogical objective, gained the relationship between pedagogical objective and learning objective, and applied the classification and writing patterns of pedagogical objective into the learning objective.Thirdly, analysed the components, structures and attributes of learning objective, and studied the relationship between learning objective and learning activities, roles, prerequisite and so on, constructed the concept model and information model of learning objective, and formalized the learning objective by formalized the atrributes. Finally, developed a demo system-learning objective module for learning system, whichbased on the computer network course knowledge ontology, and implemented analysis and establishment of learning objective. Users can establish learning objective on certain knowledge by that module, which can return a result the learning resource users needed for their learning atctives for user to choose. |
