Abstract


With the theory of distance education and the development of information technology , distance education has gradually become an important way of teaching . Formative evaluation as an important teaching tools , online testing system has become an indispensable link in the process of distance education , especially in the separation of teaching and learning , online testing system to give student interaction and feedback is particularly important . And the popularization of online learning , on the one hand , a good background and opportunity for the research and development of online test system , on the other hand , also put forward higher requirements for online testing system . Online test system in the past , has been teaching a lot of convenience , such as breaking the limitations of time and space , reducing the burden on teachers marking and registration results . However , in these test systems , the questions between isolated test implicit in the concept is difficult to systematically presented . Give the learner feedback and evaluation system too mechanical a single , it is difficult to give effective guidance to learners . Comprehensive analysis of the situation and the demand of the online testing system , we designed an ontology-based online test system provides three different types of tests to meet the testing needs of different levels . Uses adaptive tests based on item response theory in self- test module enables students to carry out personalized tests to improve the efficiency of the test . At the same time , the use of ontology technology to the field of knowledge and its relationship standardized description and systematic organization and ontology knowledge and questions associated ontology model based on the knowledge points of Test Paper Strategy and evaluation feedback strategy . When the test is completed , the system will not only standard answer students answer feedback to the students, and through ontology queries reasoning , found that the student is not a good point of knowledge , learning advice given target . Online test system , testing , feedback , and evaluation of all three reflect the online test system optimization and improvement to meet the need of the student's personality test , enabling students to self-test and self- diagnosis self-promoting purposes.
