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.

错误概念导向的标准为基础的评估资源教师在生命科学（MOSART-LS）项目开发严格的分心驱动的多项选择评估工具，帮助生成基于证据的措施MSP项目的影响K-8教师的生命科学学科知识和相关的教学内容知识。美国国家研究理事会的科学标准和美国科学促进会的科学基准作为一个框架，为年级适当的内容，教师应掌握。这项工作利用同行审查的学生概念研究，以产生专门的评估。 这些评估衡量教师在生命科学中持有31个K-8内容标准中每一个所代表的公认科学观点的程度。该项目正在开发250个有效的新项目，并从全国代表性的8000名学生和他们的教师的样本中收集数据，表征两者的内容知识。测试项目的子集被组织到工具中，并由内容专家进行验证。当添加到现有的测试项目库开发的一部分，早期的努力，侧重于物理科学和地球/空间科学，这些新的生命科学项目还允许建设“一般科学”的仪器，以衡量所有NRC内容标准在K-4和5-8级带教的概念。将这些测试纳入MOSART在线评估系统将使管理更容易，并允许参与MSP的数据汇总。心理测量模型的应用与认知研究结果相一致，用于建立量表和子测试，准确衡量小学和中学生命科学教学所需的科学理解。这些工具可用于诊断目的，在专业发展之前确定参与者的强项和弱项。通过增加一个后测试管理，教师知识的变化可以衡量和特点。该项目是提议者早期努力的直接成果，包括视频“私人宇宙”和MOSART。
