Design And Implemnetation Of High School Physics Online Examination System On Flex

With the high-speed development of information technology and its wideapplication, many high schools across the country have started to promoteinformatization, and gained certain achievements, such as office automation. However,it hasn’t been applied a lot in major subjects. the vast majority of high schools still usemanual mode for the volume, marking operation, which is much less efficient. Thehigher cost of taking examinations defects, have been unable to meet the demands of thehigh frequency in examinations in high school. In this case, this topic is proposed inview of the high school physics discipline of online examination system, in order torealize the automation of the test process. If well applied, the system can be extended toother subjects.In the process of designing the online examination system in physics in high school,the following tasks have been done step by step: On the basis of analyzing the flaws ofthe existing pattern, the corresponding solution has been put forward, and I determinedthe system USES the J2EE+SQL Server2005technology combination of development.In order to improve the ability to interface display, Flex technology is introduced. Andaccording to the modularization on the basis of the survey, the system can be dividedinto five parts: the system management module, question bank information managementmodule, on-line examination module, performance management module and theexamination paper management module. Meanwhile, each module is designed in theform of activity diagram. Finally, the system is experimented and examined in detail.High school physics online exam system adopts the automatic group volume modelgenerating test paper, and take the test monitoring measures to prevent students cheating,such as the ban on screen, print screen as well as the time synchronization and so on, sothat it can improve the impartiality and fairness of the exam. However, a series ofdefects still exist in the system, for example, the question bank is not large enough. Atpresent, the system has been successfully applied to a high school physical scienceassessment, which can effectively reduce the burden of teachers’ work, improving theirwork efficiency.
