Online Examination System Based On The Ims Qti Standard Research And Realization

With the rapid development of network technology, e-learning has made considerable progress. Online examination and testing is an important point of e-learning, good test can better reflect the student's condition and the level of grasping knowledge in the study process. At present, because of different learning environment and teaching platforms, on the different exercises and testing system the type and presentation of questions of may also be different. It makes a Question &Test System will only rely on a specific learning platform, exchange and sharing of the test item bank systems will be hard to achieve. Unexpected elements in the education system of the system cannot be reused, as one of the islands of information.Distance education in recent years in discussion mode of teaching, we found lot different from the traditional teaching process, the operation of the mechanism. For new teaching online teaching model proposed by the traditional teaching model and the difference between the new teaching model, updating the traditional education, "education" has always played a leading role, "learning" is a relatively passive and dependent process, because of teaching process from "real teacher-student interpersonal two-way exchange" into remote in time and space relative to separate"teaching" and "learning" aspects, proposed collaborative interactivelearning model.Teaching in the network model, test whether teachers evaluate students to meet the level of knowledge on the function. Is to develop a deeper level of communication and collaboration of students learning ability and ability to learn and want interaction model of this platform to be achieved through the network, you need three things:the test model of collaborative, online testing practices to support collaborative model, students network platform testing process specifications. From the start to explore collaborative testing, the test model of the collaborative study, the test must have a collaborative analysis of the key elements and the current lack of online testing system. Through the examples of traditional abstract questions peel extract structural framework, the definition of collaborative models and parameters of the subject. Then details of the current widely used international IMS (Instructional Management Sysem) Global Learning Consortium customized training and test interoperability specification QTI (Question Test and Interoperability) specification. Through the collaborative model of topics and examples QTI subject comparison and analysis. Design a model that can be converted. The model created through the collaborative online testing possible.Finally, the author of the Institute of the actual situation, the design of a compound College requires collaborative online test system design and implementation. Introduce collaborative model based on the needs of QTI system analysis and design program; of college examination process, the proposed design objectives, system architecture, and through UML Unified Modeling Language model of online examination system analysis, each sub system, detailed design and main function modules to elaborate.
