Design And Construction Of University Test-questions Library

Content and scope of modern higher education gradually widely, traditional education mode is gradually replaced by a variety of teaching methods and platforms, the subsequent, teaching appraisal way also become diversified and complicated.Under this particular environment in colleges and universities, the obvious difference between professional and specialized in non significant difference is in question, if still using the traditional way of artificial custom examination and content, so only test a job requires a lot of human resources, and the item bank for its provides a good solution.Based on computer calculation and management ability, through the construction of item bank, corresponding to the corresponding discipline provide reasonable and sufficient scale question bank, can effectively improve the efficiency of the examination work, reduce the manpower, but also can improve the rationality of the test to a certain extent, fairness, and so on.In this paper, the development of database development and management of related technologies at home and abroad, summarize learned abroad automatic examination paper generating scheme in order to realize a more reasonable test scheme, domestic research is how to ensure the stability of the examination, be artificial parameters test paper generation is given priority to, overall domestic research on the automatic group volume is relatively backward, on the one hand, and the research emphasis of this difference, on the other hand also has relationship with the national education strategy.Considering the core services that the main target for the test paper generation, this paper also researches on the existing test paper algorithm that summarize, random, backtracking, SGA, and so on, provide reference to the research of this paper.Actual design and development process, completed the university basic database application of needs analysis, considering the topic source management, examination paper generating, online examination three main functions, and based on the requirement analysis of system model design;In view of the question bank management, provides a common document text entry, at the same time provide the basic manual management interface, database information stored in the database of ZDKC and ZDZSD table;For group volume demand design optimization algorithm in order to realize the knowledge points more balanced consideration, the design of an improved genetic algorithm for automatic group volume;Consider the function of user operation requirements in terms of the classification management, at the same time to provide teachers, students and other different access interface and function, eventually consider database extension of the application design of the online test and online reading related functions., final test results reflect the system can realize the random test paper generation, professional system efficiency is higher, corresponding auxiliary operation and can realize teacher, on the interface also implements the high usability and interactivity.
