摘　　要：本文在Web环境下基于项目反应理论(IRT)设计并实现了一种自适应考试系统。通过独创的试题抽取算法,该系统能够根据考生能力动态调整试题难度,从而提高考试的准确性和效率。研究比较了传统考试与基于IRT的自适应考试系统,结果表明后者能够更精确地评估考生能力。此研究不仅引入了新型考试模式,也为教育评估领域的发展提供了新的视角和参考。This article designs and implements an adaptive examination system based on Item Response Theory(IRT)in a Web environment.Utilizing an original question extraction algorithm,this system dynamically adjusts the difficulty of questions according to the test-takers'abilities,thereby enhancing the accuracy and efficiency of examinations.The study compares traditional exams with the IRT-based adaptive examination system,demonstrating that the latter can assess examinees'abilities more precisely.This research not only introduces a new examination model but also provides a fresh perspective and reference for the development of the educational assessment field.
