The Computer-based Orthographic Processing Assessment (COPA) is a newly developed assessment to measure orthographic processing skills, including rapid perception, access, differentiation, correction, and arrangement. In this study, cognitive diagnostic models were used to test if the dimensionality of the COPA conforms to theoretical expectation, evaluate individual items’ quality, and examine the validity and the learning sequence of each skill. Results showed that the COPA captures five distinctive operating attributes, but some items could be revised to increase their item quality. Correlations with external variables confirmed that performances on the COPA are more strongly related to literacy outcomes than to oral language outcomes but that the COPA also demonstrates discriminant validity relative to even proximal measures of word reading and spelling. The mastery probabilities and best-fitting hierarchical model indicate that four of the five attributes follow a learning progression that is consistent with information processing theory and that was assumed by developers of the COPA.

基于计算机的正交处理评估的评估:认知诊断建模的应用

基于计算机的正字法处理评估 (COPA) 是一项新开发的评估,用于衡量正字法处理技能,包括快速感知、访问、区分、校正和排列。在这项研究中,认知诊断模型被用来测试COPA的维度是否符合理论期望,评估单个项目的质量,并检查每个技能的有效性和学习顺序。结果表明,COPA 捕获了五个独特的操作属性,但可以修改一些项目以提高其项目质量。与外部变量的相关性证实,COPA 的表现与读写结果的相关性比与口语结果的相关性更强,但 COPA 也证明了与单词阅读和拼写的近端测量相关的判别有效性。掌握概率和最佳拟合层次模型表明,五个属性中的四个遵循与信息处理理论一致的学习进程,并且由 COPA 的开发人员假设。
