Research in Standards-Based Science Assessment

该项目致力于对科学评估措施的类型进行研究，这些措施提供关于学生结果的数据，这些数据是有用的、准确的，并允许进行有效的推断。该项目的目标是帮助系统性举措衡量其改善学生科学学习的努力的影响，并利用评估结果提供信息和改进教学。该项目提出的问题包括：“哪些类型的措施最适合于基于标准的教学？接受基于探究的科学教学是否比其他因素更能提高基于标准的科学评估的某些部分的分数？教师如何利用评估的结果为实践提供信息？培训是否会改变教学？”这项研究将招募加州小学、初中和高中的样本，并进行前后测试、教师访谈和学生访谈和调查问卷。这些数据将在多维项目反应模型中进行分析。

This project seeks to conduct research on the types of science assessment measures that provide data on student outcomes that are useful, accurate, and allow valid inferences. The goal of the project is to help Systemic Initiatives to measure the impact of their efforts to improve student learning in science and to use assessment results to inform and improve instruction. The questions addressed by the project are such things as: "what types of measures best inform standards-base instruction? Does exposure to inquiry-based science instruction improve scores on some components of standards-based science assessment more than others? How do teachers use results from assessment to inform practice? Will training change instruction?" The study will recruit a sample of schools in California at elementary, middle, and high school levels and administer a pre- and post-test, a teacher interview and a student interview and survey questionnaire. These data will be analyzed in a multidimensional item response model.
