The Experimental Test System For Computer Language Courses Based On Network Environment To Develop And Research

This thesis aims at solving the problem of computer programming tests in teaching and studying and developing the computer language experiment system in network environment.Computer language experiment system studied in the thesis takes the pattern of NCGT for the reference. NCGT is a LAN-based network testing system, in which level-2 and level-3 test the examinees' ability of program designing and debugging. As a normal testing system, computer language experiment system is also based on the LAN environment development. The login interface and the testing procedure keep high consistency with NCGT.In the development of computer language experiment testing system, requirements analysis, general design, detailed design and code testing are performed in order. In the detailed design step, the program flow chart of all sub-modules is worked out and encoded with VB programming tool according to the program flow chart. The server database employs SQL Server 2003 to manage and maintain, while the database of the examination computer employs Microsoft Office Access 2003.The system studied in this thesis can be divided into student examination end and teacher management end functionally. Teachers perform the management and maintenance of the examination database, students' information and examination results at the teacher s' end, while students perform login, examining and handling in papers at the students' end. The system has an excellent grading function which supports the grading both at teachers' end and the students' end and displays the reference answer and the score at any time during the mock examination, a friendly examination logging interface, a secure system which supports the second logging-in and real programming environment to change computers to finish the examination or restart the examination and a countdown timer to display the remaining time.Currently, Computer language experiment system studied in the thesis basically completed and supports the programming examination of C language and VB on computer. Due to the system's high consistency with NCGT, it greatly accelerates the students' study interests. Meanwhile, it is convenient for teachers to have a good knowledge of the students' study. Through experiments, the system fully meets the requirements of the computer language experiment examination.
