MOSART-LS: Misconceptions Oriented, Standards-based Assessment Resource for Teachers in the Life Sciences

面向错误概念的基于标准的生命科学教师评估资源(Mosart-LS)项目开发了严格的干扰因素驱动的多项选择评估工具，帮助生成MSP项目对K-8教师生命科学主题知识和相关教学教学知识的影响的循证衡量标准。国家研究委员会(NRC)的科学标准和AAAS科学基准作为教师应掌握的适合年级的内容的框架。这项工作利用同行评议的研究学生的概念，以产生专门的评估。这些评估衡量教师在多大程度上接受生命科学中31个K-8内容标准所代表的被接受的科学观点。该项目正在开发250个有效的新项目，并从具有全国代表性的8000名学生和他们的老师的样本中收集数据，以表征两者的内容知识。测试项目的子集被组织成工具，并由内容专家进行验证。这些新的生命科学试题库是作为早期侧重于物理科学和地球/空间科学的工作的一部分而开发的现有试题库的一部分，这些新的生命科学试题库还允许建造“一般科学”仪器，以衡量K-4和5-8年级的所有NRC内容标准所教授的概念。将这些测试纳入Mosart在线评估系统将使管理变得更容易，并允许收集参与MSP的数据。心理测量模型的应用与认知研究结果相一致，用于建立量表和分测试，准确衡量小学和中学生命科学教学所需的科学理解。这些工具用于诊断目的，在专业发展之前确定参与者的长处和短处。通过增加考试后管理，教师知识的变化可以被测量和表征。该项目是建议者早期努力的直接产物，包括视频《私人宇宙》和莫萨特。

The Misconception Oriented Standards-based Assessment Resource for Teachers in Life Science (MOSART-LS) project develops rigorous Distractor Driven Multiple Choice assessment tools that aid in generating evidence-based measures of MSP projects' impact on K-8 teachers' life science subject-matter knowledge and relevant pedagogical content knowledge. The National Research Council's (NRC's) Science Standards and AAAS Science Benchmarks serve as a framework for the grade-appropriate content that teachers are expected to master. This work utilizes peer-reviewed research studies of student conceptions in order to generate specialized assessments. These assessments measure the degree to which teachers hold the accepted scientific view represented by each of the 31 K-8 Content Standards in life science. The project is developing 250 valid new items and gathering data from a nationally representative sample of 8000 students and their teachers, characterizing the content knowledge of both. Subsets of test items are organized into instruments and validated by content experts. When added to the existing test item bank developed as part of earlier efforts that focused on physical science and earth/space science, these new life science items also allow for the construction of "general science" instruments to measure the concepts taught across all NRC content standards at the K-4 and 5-8 grade bands. Incorporation of these tests into the MOSART online assessment system will make administration easier and allow for the aggregation of data from participating MSPs.The application of psychometric models aligned with cognitive research findings are used to establish scales and subtests that accurately gauge the scientific understanding needed for teaching elementary school and middle school life science. These instruments are useful for diagnostic purposes, ascertaining the strengths and weaknesses of participants prior to professional development. By adding a post-test administration, changes in teacher knowledge can be measured and characterized. The project is a direct outgrowth of the proposer's earlier efforts including the video "A Private Universe" and MOSART.
