The Studies About Examination System Based On The Course Of 《C Programming》

Computer Aided Instruction has become an important part of higher education. The use of test systems, electronic test technology and Automatic Test Paper Library system is an important computer-aided instruction research. However, in the test database set up, use, maintenance, operator error will inevitably occur. This test required the Treasury to evaluate the test in order to improve the quality of questions, making the examination system to achieve better teaching results of the inspection mission. This article focuses on the response to《C Programming Language Design》curriculum developed by the use of the composition of the examination system, set up a databank of examination questions, examination papers, as well as the automatic generation of test evaluation.Examination system is to use the computer as a test instrument to replace the traditional pen and paper. Major exams in the computer, through the use of test system to examine the practical ability of students to test the true level of candidates. In addition the examination marking system has automatic functions in the process of marking to avoid causing human error. Because of the examination system is a random question, each candidate different questions by pumping so that candidates can not corrupt, so can be a better test of the actual level of candidates. Because of《C Programming Language Design》is the foundation for public school subjects, the large number of classes each examination paper to be published many papers, consume a large amount of paper. The use of the examination system, the paper does not require a large number of papers published, saving resources and at the same time filing papers at the time, very convenient and save a lot of space, paper storage more secure.In response to《C Programming Language Design》curriculum developed by the use of the examination system, the use of test system design Hierarchy. Designed to operate using the VC system layer, to achieve powerful, stable performance, with good human-computer interaction interface; Designed using the Microsoft Access data layers, database management and maintenance. The entire system be simple to operate and easy to use. At a time when the use of the examination system, automatic Paper system is an important study. Automatic Test Paper is to achieve paperless examination system, the examination of standardized and personalized, network-based online learning and distance education, such as the basic test. Paper is automatically put artificial intelligence experts in education technology and human knowledge and experience combined automatically by a computer to design the content of papers, and papers to make computer-generated class to achieve the level of experts. Automatic Test Paper system automatically generated to ensure that papers that meets the needs of users, but also ensures its scientific nature, randomness, objectivity.Implementation of intelligent computer to Paper, on request there is a powerful, scientific and rational design of the questions the premise of the Treasury. Therefore questions the Treasury on the design in the functional to be considered apart from the questions and answers to be able to input, modify, delete, the more important is their design to provide efficient Paper Services, Paper systems in order to be able to accurately and quickly from call the required questions and answers questions. Choose the appropriate type of test, the test system can test a comprehensive knowledge of the required points for the latter to provide the convenience of automatic marking, marking systems enable rapid, accurate evaluation of the papers submitted.In the marking process, to deal with the blank is a matter of concern. Taking into account the characteristics of the blank, that is not the only fill in the content, which the students filled out the existence of the contents of reference although the answer is not exactly the same, but the situation is still right there, and this is often the . Resolve this problem, the methodology is reviewed manually add the link. Marking operation in the implementation of three components for processing. Evaluation machine first. Uniform treatment of all topics, the students answer with reference to the contents of the answer match, the answer will be the blank in the subject does not match the tag. And is the manual review. Teacher marking required for the front aspect of the subject which have been marked for review. Finally the operation of nuclear sub. Manual review of the examination system will be the subject of scores of students scoring in each grade is added, the accounting of the total score.Of questions in order to test the quality of papers, but also test the quality of teaching, it is necessary to carry out the evaluation questions. The quality of teaching involves the whole process of teaching and testing the quality of teaching is an important means of assessment score, and score test can truly reflect the quality of teaching and examination of the proposition is of particular importance. Questions too difficult, too partial, the students will score low; too easy proposition, it is bound to reduce the goal stipulated in the syllabus so that students score high grade students do not distinguish between good or bad. How to conduct a scientific examination of the proposition, the ideal test of student achievement, teachers need to consider the question seriously.In the course of the evaluation questions, the use of four or more difficult target, coverage, reliability and credibility of the distinction between the evaluation questions as the quality of the main target. Among them, the more difficult questions with the difficulty of the questions that the weighted average. Coverage of the basic idea is to test the more extensive the coverage, then the subject of cross-correlation between the smaller, the greater the contrast. The correlation coefficient is the substance of the questions reflect the size of the coverage. Discrimination is the ability to mark questions grade students distanced themselves from the real distinction from the scores of students on knowledge of the situation. The credibility of the paper describes the total exclusion of the bad at all after the title of the random error part of the remaining percentage of the total variance, the problem of small random errors, then the credibility of papers on high, and vice versa to reduce the credibility of .In the development of the design process has encountered a major problem, namely, how to test a library screening questions do not meet the requirements. To address this issue, mainly to consider the following solution. At Treasury questions, add information to describe the field and auxiliary field, through an analysis of the results of the examination, comparison and identification of suspicious items. Because one of the entry, edit the test error can be relatively easy to determine. As for the topic because of one of point of view, such factors as ease of suspicious questions arise, the information required to describe the integrated study fields and auxiliary fields to solve problems. Because of the examination system, the Intelligent Test Paper with a certain degree of randomness, of the test questions library at a time is not necessarily all examinations taken, the number of examinations to be carried out after the library in order to make the test questions have comprehensive evaluation of the relative . In the process of thesis writing, the use of examinations for a number of experimental systems. Evaluation of the test by simulating the experimental aspect of the inspection, have been the desired effect.Examination system as an important problem, research questions and methods of evaluation of the theory will be to continue in-depth research and development continue. Significance of the research thesis is not only a test system implementation and evaluation to do a simulation test and, more importantly, yes, right questions for a preliminary evaluation of and research on the development of sophisticated test and perfecting the system a try, Design and implementation for future database application to further research and provide a viable and meaningful basis for the theory and practice.
