Psychometric Issues in Mathematics Assessment: Multiple Raters, Indicators, & Viewpoints

9255272 Wilson Mark Wilson和Raymond Adams提出的这一建议旨在开发一种新的测试技术，重点关注学生对数学的理解。这是一项心理测量学研究，旨在开发具有足够灵活性的多维模型，以检验测试的信度、效度和公平性。研究人员使用项目反应理论中的方法论方法，使用最近在加利福尼亚和澳大利亚墨尔本进行的性能测试。该项目将扩展测量模型以纳入多维度，开发计算机程序以校准项目和评分者，重新分析数学中的绩效评估以研究每种评估模式的有效性，并收集绩效评估数据以研究学生测量的纵向方面。

9255272 Wilson This proposal from Mark Wilson and Raymond Adams is intended to develop a new testing technology that focuses on student constructed understandings of mathematics. It is a psychometric study to develop multidimensional models of sufficient flexibility to examine test issues of reliability, validity, and equity. The investigators use a methodological approach within Item Response Theory using recent performance tests carried out in California and Melbourne Australia. The project would extend measurement models to incorporate multidimensionality, develop computer programs to calibrate items and raters, re-analyze performance assessments in mathematics to study validity of each mode of assessment, and collect performance assessment data to study longitudinal aspects of student measures.
