Research And Implement Of Intellectualized Test Library System Theory

Computer-Assisted Instruction is one of computer application-mode It is based on the artificial intelligence science,cognitive science, computer science education theory and psychology.It is a new domain of computer application technique,and represents a new education thought and teaching method.Item bank system is one key part of CAI system which can carry through generating test paper and analyzing test paper, and it is an important method to assure test item having better quality, keeping level stabilization and getting better test and diagnoses.Accor- ding to problems of low intelligence,generating test paper'S low effici- ency and SO on in item bank system,this paper firstly analyses the relation between knowledge point network and test paper based on the research on knowledge point and RelatiOnships between knowledge points.Secondly,this paper analyses and construct multi-constraint problem which should be considered during intelligently generating test paper based on research on manual generating test paper,test theory and knowledge point hiberarchy,builds up math description of single and group test paper,realizes single and group test paper generation using adaptive Genetic algorithm,and it is proved that it has higher efficiency than other algorithms of generating test paper through experiment.
