Design and Implementation of Self-adaptive Test System Based on Item Response Theory
摘要
Abstract
According to the adaptive learning characteristics,analyzing the model of parameter about item response theory,use maximum likelihood estimation method to calculate learner ability parameters. Based on the main function of system structure and system analysis of adaptive test system module,construct the test system,and put forward the question estimation strategy and information interval estimation strategy of the testing system,so as to improve the test speed and computing speed. Calculate the learner characteristic level and question's difficulty coefficient according to the learner's actual test,and develop the adaptive test system based on computer basis course.关键词
