Design Of Adaptive Testing System Based On Item Response Theory

With the rapid development of cross-education, examination in various fields has become very wide, which for more in-depth examination of the study.Currently, The main theories guide exam study with classical test theory and item response theory.Classical test theory has been difficult due to its adaptation defect status, item response theory with its unique advantages to receive more attention.As an open network technology, distribution features make the gradual transition to a paperless examination to improve the test efficiency and reduce costs, while subjects were more objective and accurate evaluation.Based on the systematic study of the item response theory and test theory, based on the item response theory and three-parameter logistic model, designed a Computerized Adaptive test system based on. NET.The system's main contents include:System-related theoretical research, system analysis, system-related technical support and system structure, system interface and key code, etc. The program not only focus on the validity of the exam, test security, and taking into reasonable distribution of knowledge points. Research is based on Item Response Theory for Adaptive Testing System Design and Development has a guiding role.
