Design And Implementation Of Auto-Grading System

The computer in teaching the most important application is to help teachers in test administration, while it is on the computer in teaching more difficult to achieve a link. With the test types and methods of growing and examination requirements are increasing, there is no doubt the workload of teachers will also be growing, and that its work is very cumbersome, and also very easy to make mistakes, we can foresee a relatively , the traditional mode of testing methods are now increasingly unable to meet the needs of the modern examination. Therefore, to explore computer examination management system for the exploration and practice of research of great significance, it can reduce the duplication of teacher workload and significantly improve the efficiency of the teacher's vital work, but also to improve the quality of the examination, so that more accurate and timely test results .As it is only short time after our Research Institute was set up, personnel and investment funds are relatively limited, therefore, a lot of repetitive work, means the introduction of information technology is imperative. We as a push point, were compared with immediate start test administration, in which, we have chosen graders management as a starting point of this system.The system according to my business training college where the actual business needs and to develop, and examinations are important tasks of training college, including the generation of examination questions, the examination process, graders, performance analysis, landing, and a lot of work papers from the examination management start of the repetitive work of both the graders management, and basically out of the paperless title, can not automatically be sentenced to manual reading of the sentence reading, and long-term preservation examination questions, transcripts, papers analysis table. Basically resolved the original operations manual, taking up too much teaching resources, teachers and other shortcomings of the heavy task of batch volumes. Improve the working efficiency, saving the cost of the exam.This system is composed of C # 2005 with SQL SERVER 2000 database implementation. In the tool selection borrowed a number of third-party grid control, because this emphasis on system architecture design description, so they do in this introduction. System, the future (through another project has been achieved) will support the students-paper examination, not just a simple graders management. Currently achieved through the computer input test answers, and automatically calculates test scores, records of students answer content analysis generated papers, transcripts, and has printing capabilities. On the part of the computer can not automatically graders subject, the system programming interface to provide manual graders. Academic staff to student performance through the system queries to generate examination papers.This paper describes at greater length on the analysis of my design ideas, which, in particular, reflects the UML modeling approach. Chapter 1 for my company's profile and design of the system of reason. Chapter 2 and Chapter 3 in great detail my thoughts before and after the design software, including data processing, flow patterns, etc., these two chapters, I covered the focus of this chapter is what I use UML modeling method of an understanding of the expression. Chapter 4 of this presentation for the system maintenance due to the nature of my work is more interested in application and system implementation, most of their daily work is to maintain the main, so that any system has been designed to achieve is very important, but in its maintenance, more important, is often an outstanding technical ability to achieve, not just a good idea, advanced technology, more importantly, will depend on whether the latter part of the promotion of maintenance to keep up with, even in my relatively sophisticated ERP in the industry have similar argument shows the importance of the implementation of system maintenance, so I hereby join this chapter, for reference, because I have limited experience, is still immature, so only briefly in the company of my implementation of the system point of experience Sharing the next, but also invites further evidence.This design and implementation due to the short time, coupled with my C # and UML elements belong to a new contact, therefore, essential to be errors or omissions, asked the teacher to understand.
