| Abstract: | CAT is a computerized test based on Item Response Theory.It has overcome many disadvantages of the traditional test,and can improve personalized learning.This paper discusses a lot of effective application strategies made by CAT,such as: the control of exposure rate,parameter optimization,optical choosing of topics and maximum information scale.Meanwhile,limited by the present technology level,the exactness and fairness and scoring of CAT are waiting for further solving. |
