Design And Implementation Of Online Examination System Based On Genetic Algorithm

With the economic development and popularization of computer technology,the development of the society and the lifelong education idea,the emergence of test library management system.Test library management system using the computer information management technology and database technology to the construction and management of item bank,before every exam,according to the teacher's request,choose a topic from the question database,automatic generation of test paper.This ruled out in the examination process of human factors of images,to ensure that the examination of quality,maintain the test of objectivity,impartiality and accuracy,the macro guidance and management is helpful to the teaching work,the scientific management of teaching courses into reality.At the same time,reduce teacher proposition work burden,the majority of teachers from the arduous work of teaching more free,devote themselves to the study of teaching methods and improving teaching quality.Automatic test system at present,the rapid development of the computer science,the product of educational measurement theory and artificial intelligence theory combined,is from the traditional education to a new education evaluation system in the development of modern education,is an important part of China's education examination system.At present,in all type of mass education examination,the level of examination specialized technical personnel,occupies an important position to test the level of occupation technology and employed in testing cadres.Therefore,to realize the automatic test system is the development trend of China's education examination management.In this thesis,based on the analysis of demand,through the application of genetic algorithm to the online examination system,the construction of a three layer structure based on the ASP.NET language and a multi functional online examination system SQL Server 2005 database for the background.To realize the automatic generating test paper according to the topics of teacher input parameters and rules,selecting a set of questions from the test database,makes them all properties meet the perform maneuvers established,survive a consistent with the syllabus,wide coverage,focuses difficult to easy points,test papers distribution and user requirements;the accuracy an d science is very high,can measure the students with the real achievement;ensure the test objective,make examination fair and accurate,more scientific and rigorous excluding the impact of human factors in the process of examination and the decrease of propositional standards,grading standards,thus ensuring the quality of examination.
