The Development of Multiple-Strategies Cognitive Diagnosis with Polytomous Response
Zhu Yufan · Journal of Jiangxi Normal University · 2015
Polytomous models can give more information for score than dichotomous. Based on the application of the cognitive diagnosis with polytomous response,the current study developed a multiple-strategies cognitive diagnosis with polytomous response. Examinees using the problem-solving strategies and score independent are considered,the paper adopts the following methods for multiple-strategies cognitive diagnosis with polytomous response. Firstly,transform the score of polytomous to the score of dichotomous. Secondly,use the multiple-strategies cognitive diagnosis with dichotomous response to find the problem-solving strategies of examinees. Finally,employ the multiple-strategies cognitive diagnosis with polytomous response to diagnose students ' attribute mastery patterns. Monte Carlo method was employed here to the feasibility of the multiple-strategies cognitive diagnosis with polytomous response,the results show that the method is effective and reasonable.
