中文摘要:
      二十世纪下半叶 ,项目反应理论在国外得以迅速发展和推广。以这种理论为基础的测试可以根据被试对一个或多个项目的反应进行个体特性评估 ,同时还可以求出这种特性评估的测量误差。因此 ,这一理论在计算机适应性测试研究和开发中将大有作为
English Summary:
      The late 20 th century witnessed abroad a rapid development and a wide application of the Item Response Theory (IRT). A test based on IRT can be employed to evaluate an examinee's individual trait by his or her response to one item or more and to calculate the measuring error of this trait. Therefore, this theory will play a great role in the research and development of computer-aided adaptive testing.
