The Analysis And The Design Of The On-line Study And Examination System

Along with computer network technology unceasing development, will establish in the above distance learning into modern education technology in the future one of development directions, the test will take the distance learning a sub-system also to become an important research area. The Internet openness, the distributed characteristic and caused the test based on the Internet huge computing power to break through the time and the spatial limit, the test already may in local carry on, might also in different carry on, has developed the test flexibility greatly, will therefore be later takes a test the development tendency based on the Internet network test way.Compares with the traditional test pattern, on-line test has the incomparable superiority, it may the traditional test process in man-power volume, the examinee take a test, examine test papers artificially, the performance appraisal and the examination paper analyzes each link to reduce to one to two links, has shielded all artificial direct intervention test possibility nearly, not can only save the massive time, the manpower, the physical resource and the financial resource, moreover may also improve the score on the test large scale the objectivity and the fairness.This article studied and has designed one based on the WEB on-line study and the test system, this platform realized has been advantageous for the teacher "to test" with the student "study", take the student as the main body, the teacher for the leadership, realized the interactive network study and the test environment. This article carried on the analysis to on-line test system, to design and to realize emphatically. In this test system, the student may to choose the curriculum and the content carries on the test, and gives the examination result, through the test student may understand that oneself to studies the knowledge to keep abreast of the situation; Moreover, on-line test system also has the proposition, the question bank management, the automatic group volume, the test platform, to examine test papers, the examinee to manage, functions automatically and so on result issue, has realized the test paperless, reduced a troublesomeness which formerly the old style test brought.Compares with the general test system, this system supports more topics, also has the objective topic, also has the subjective topic test; Simple Yi Yong B/S pattern: The examinee test and Cha Fen, the teacher publish the volume, the evaluate examination papers, the leader inquiry and so on to use the B/S pattern development, does not need to install the client side, is advantageous for the maintenance and the promotion, and can with the school or the enterprise existing Intranet integration; In question bank design, group volume formally as well as aspects and so on grading form, although the function is similar, but the procedure respectively has the bright characteristic, is the good volume system, has the nimble question bank, many kinds of volume patterns and the science reasonable takes the topic group volume strategy; Practices and takes a test two big functional modules, both are advantageous for the test, and promoted the study enormously; In because the test process other reasons exceptionally withdraw, may allow to participate in the previous test; Complete user management and jurisdiction control, multistage role management: Including the system manager, the teacher teacher's aids and the examinee three jurisdictions, three different jurisdiction's reasonable establishments have assured the system safety, the steady operation effectively; The system provided has been advantageous alternately, and had certain effective management operation; Brand-new contact surface design, full of meat actual effect.Based on above these, this system will have the function to be stronger, the performance to be higher, the extension to be better, an implementation cost lower characteristic. In brief, regardless of reduces from teacher's work load looked from the education trend of development that "on-line test system" has the application prospect very much, the present paper will have the use value very much.This system uses based on the Web B/S three architecture, namely the user boundary layer, business level and the database level, do not need to install any application procedure peacefully on the user machine, the application procedure may install, in business level institute is at on the computer, the test question deposits on the database server, therefore the Web structure has a better security. This system uses WindowsNT/Windows2000 the server function, SQL the SERVER 2000 data bank administration function, as well as the ASP formidable back-office support function, founds a function to be complete, the easy to operate, the highly effective practical on-line study and the test system, adapt the new time study and the test informationization, the network.
