Design And Implementation Of Online Examination System

The design of the online examination system is based on computer technology a nd network technology,intellectualized technical service teaching as the concept,to s olve the key problems encountered in teaching practice as the guidance,to the major ity of teachers and students' teaching needs as the core.It has many advantages--com plete functions,can break through the time and space constraints,can solve the tradit ional examination problems,can correctly assess the students' learning situation and s-o on,for example.This thesis deeply analyzes the problems of the online examination system,suc h as low efficiency and quality of the test paper,low system resource utilization rate,and high complexity of system structure design.Next,we were aiming at this probl em,combining with the actual situation of schools and the design strategy of the sys tem,then the design strategy and implementation method of online examination syste m based on B/S framework was proposed.The main work of the paper includes:(1)This paper expounds the theoretical knowledge of the online test system,and proposes an improved idea for the problems that arise in the application of system design and implementation of random algorithms and traditional genetic algorithms.T he functions of the system are perfected on the basis of the optimization algorithm.(2)Multi-dimensional and multi-faceted analyze user requirement,which determine modular design method and development technology.According to the method and t echnology,the three functional modules of system—system administrator function mo dule、examinee function module and teacher function module are designed.The com bination of each module realizes the specific functions which include intelligent test paper、question bank、test paper management,online test,review and inquiry,etc.(3)Describe the implementation process of each function of the system,and test the system with the black box test method.The results of a large number of tests s how that the design method of the article can reach the preset goal.The design and implementation of the online examination system solves some of the problems existing in the traditional examination,provides a modern testing envir onment for teaching achievements,realizes the diversified construction of teaching res ources,and promotes the separation of teaching and testing.
