System Design And Implementation Of University Examination Graphical Analysis Based On Web

Examination analysis is helpful in determining whether the examination proposition is reasonable,whether the grading is scientific,and whether the examination is organized rigorously.It also provides important information for improving the university examinations.It is found through the investigation of domestic and international examination analysis systems that the majority of existing systems are based on ASP,and the analysis results are represented in the form of data and tables,etc.Few of existing examination analysis systems can be run on web servers and little analysis results are represented by figures and diagrams.While many researchers are engated in education measurement and statistics theory,few of them apply these theories to university examination analysis.As a result,the study of evaluation criterions of examination difficulty,discrimination,confidence and validity are not in-depth enough.Since the university student information database can't be seamlessly connected to the teaching information database,teachers are required to import student data repeatedly.This means a significant burden for examination analysis of a university with nearly ten thousands of students.In order to solve the above-mentioned problems,this paper deals with the system design and implementation of university examination graphical analysis based on web.The work is based on the top-bottom strategy in software engineering,education measurement theory and statistical theory.Starting from the analysis of student grades statistics and examination quality,this paper investigates the criterions of difficulty,discrimination,confidence and validity,and then determines the evaluation criterions of examination analysis systems scientifically.A JSP based university examination analysis system runnable on any web servers is then presented to intergrate existing student information database and teaching information database.In the system development,the development tools including JSP and Visual Basic,and database tools including MYSQL and Excel hybrid programming,are used to draw the frequency histogram of examination grades.With a user-friendly interface,the web based graphical examination analysis system is simple to operate and adpated to expansion.It generates detailed analysis results in an intuitive and graphical form.All these advantages make it a convenient tool in improving university examination.By mining the student grades,it is possible to find out the problems in teaching and examination,and then improve the examination quality and proposition level..
