针对目前国内外认知诊断模型所适用的项目大多为0-1评分,不能满足实际工作中丰富多样的测验资料的缺点,提出一种基于HO-DINA模型的诊断模型,对大学生心理多级评分认知进行研究.其是拓展具有良好发展前景但仅适用0-1评分数据资料的HO-DINA模型,将该模型拓展至多级评分适用范围,新模型参数的估计采用MCMC算法.对所提出的模型进行了性能研究,并用实验证明了新模型的有效性.模型仿真结果建议属性诊断个数为7个以下,以保证属性模式判别准确率高于80%.%Currently,the scoring rule of Chinese and foreign cognitive diagnosis models suitable for most projects is 0~1, which cannot satisfy various test materials in practical work. Therefore,a cognitive diagnosis model based on HO-DINA model is proposed for students′ psychological multi-level score research. It has good development prospect but is only adaptive to 0~1 scoring for data materials adaptive for expansion of multi-level scoring. The MCMC algorithm is adopted to estimate the parame-ters of the new model. The performance of the proposed model was researched and its validity was demonstrated. The diagnosis number of the suggested attributes for simulation results of the model is less than 7,so as to ensure that the judging accuracy of attribute mode is higher than 80%.
