CAREER: A Comprehensive Modeling Approach to Cognitively Diagnostic Assessment: Methodological Developments and Practical Implementations

这个项目将从认知诊断模型（CDM）框架开发一个8年级的比例推理评估。CDMs是专门开发的心理测量模型，用于诊断是否存在解决测试问题所需的细粒度技能或过程。基于CDM的评估可以提供被认为更具诊断性和描述性的信息，因此在应用教学环境中更相关。该项目还将引入一个综合框架，使此类评估的构建、管理和分析更加切实可行。该项目将开发新的模式、方法和计算机程序，以促进清洁发展机制的更广泛应用。

This project will develop an 8th grade assessment for proportional reasoning from a cognitive diagnosis model (CDM) framework. CDMs are psychometric models developed specifically for diagnosing the presence or absence of fine-grained skills or processes required in solving problems on a test. Assessments based on CDMs can provide information deemed more diagnostic and descriptive, therefore, more relevant in applied instructional settings. This project will also introduce a comprehensive framework that will make the construction, administration and analysis of such assessments more practicable. New models, methodologies, and a computer program will be developed in this project to facilitate wider applications of CDMs.
