Based On .net Basic Computer Application Course Correcting System

With the development of information technology and computer penetration rates rising, the computer has in-depth to our study, work and life in all areas。Learn basic computer knowledge, to master the computer's basic operations and skilled use of Office productivity software has become a modern society the most basic needs. To meet this trend, almost all colleges and universities nationwide to open the "Computer Application" course.The university where I work in proposed One Body Two Wings of the school thinking, the idea of which one concept is to strengthen the students in computer. Therefore, "Computer Applications Foundation" as the basis for all computer courses has attracted increasing attention. To improve the "Computer Application" for teaching effectiveness, to ensure that students meet teaching requirements, the school's teaching of the curriculum was reformed, with sub-module of teaching, sub-module test and to test Place of practice way of teaching. The reform measures to improve the teaching effect indeed played a very important role, but in practice face a challenge in that exam more times since and a large number of students, classroom teacher workload is very big hand mark the papers, but also inefficient. Therefore, one can develop accurate, rapid and correcting all the "Fundamentals of Computer Application," Course Test of correcting the system is very necessary.In this paper, "Computer Application" course content and examination types in terms of correcting the system requirements analysis, and based on the function of the system structure has been divided. System consists of answers to test center element generated documents, papers, and mark the results of data collection marking the three major functional blocks. With the help of use case diagrams, data flow diagram, business process flowcharts, IPO plans, and program flow chart logic diagram, etc. The system was design and detailed design of each module. Finally, using VB.NET as the development language, using Microsoft Visual Studio. NET 2005 as develop tools, using XML as a data transmission, processing and storage methods to develop of the system implementation.In tests, the system performance of all scheduled requirements are met. First, the system is stable, all kinds of exceptions can be handled correctly. Second, the system interface is simple and clear, simple, various actions can be found at the interface directly imported, with good interaction. Again, the system intended functions have been realized, to mark the basis of computer application courses for all types of questions, with high availability. Finally, the system speed and mark the papers, correcting the results are correct, with very good results. In short, the system has good performance and high practical value. However, as time is so short, the system does not automatically generate functional test center per file, like adding in the improvement of follow-up.
