Research And Implementation Of Test Creation From Item Bank Based On Web

With the development of science and technology and society, the modern educationtheory and the measurement standard changes, changes in test mode is to improve theefficiency of learning, a good method of self-regulated learning strategies. Onlineexamination is a kind of new test model, is a hotspot of current application in education.It is the application system based on network, has the characteristics of the network isnot limited by regions, resources sharing. Can let the teachers and learners to test thelearning effect, timely and objective discovery learning process, to adjust teachingstrategies and learning strategies, improving teaching and learning efficiency.The main content of the test results is based on web examination system in thepapers, so the teaching effect of the judgment directly affected by the impact of the paper-making strategy. Based on the test paper online examination system strategies andalgorithms are the focus of this paper, several existing paper-making strategy andalgorithm analysis study, combined with a huge number of exam questions HarbinInstitute of Petroleum, a variable number of candidates feature, analysis of severalstrategies and algorithms group title advantages and disadvantages, including thecontents of the attribute parameter settings, the group title, group title way analysis isbased on random questions Algorithmic questions questions and dynamic adjustment ofthe coefficient of difficulty, based examination system, the algorithm designed andimplemented to enhance the the group title speed and questions diversification, the use ofthe examination system has been fully demonstrated. This algorithm not only solvedpapers difficulty factor is difficult to determine, but also improve the speed andefficiency of extracting and assembling. Based on the dynamic adjustment of thequestions the kinds of questions and difficulty coefficient random questions Algorithmicto achieve an Automatic Test Paper of the test database,2012-2013Harbin Institute ofPetroleum Computer Culture Foundation exam practice results show that the algorithmto achieve the test database group title, its teaching requirements, teaching evaluationcriteria in line with the requirements of the modern teaching theory, the speed andquality of the extraction test paper to achieve the desired effect. This paper studies thetest database data structure and data table structure, established the test database dataorganization and its data table structure design, exam test paper strategy ER diagram isgiven as well as the database table structure relationship. The system in order to improve its evaluating the objective, realistic combination of using automatic graders artificialgraders, this method is more accurate, objective and fair response teaching effectiveness,and further enhance the system’s utility. Finally, based on the above proposed tocomplete the design and implementation of web-based examination system.In this paper, on the basis of the basic research to develop a web-based onlineexamination system, the examination system combines the basis of the design theoryexam theory to develop a set of flexibility, ease of use, hardiness, scalability, as one ofthe online examination system. Harbin Institute of Petroleum Engineering2012-2013Computer Culture Foundation exam examination of the system, and achieved goodresults.
