This project develops an instrument to measure the content knowledge that teachers need to teach about energy in high school classroom instruction that focuses on mechanical energy. There is significant research that indicates that teacher content knowledge differs from what people in other professions need to know about particular domains such as mathematics, and the development of a Content Knowledge of Teaching Energy in mechanics is an extension of those research and development efforts. The project embeds the development of the instrument in a program of measuring effective teaching of physics in the classroom and develops a strong validity argument for the resulting assessment based on its use as a measure in a professional development project that intends to improve teachers' understanding of energy in physics. The research team consists of experts in physics, assessment and classroom teaching of physics. The collaborative project includes researchers at Rutgers, University of Maine, Seattle Pacific University, Facets Innovation, and the Educational Testing Service.The project uses a framework for effective teaching developed in the Measures of Effective Teaching project funded by the Gates Foundation to construct a theoretical framework for the teaching of mechanical energy. That framework includes items and tasks based on instructional practices in the classroom that can identify the extent to which the teacher understands both the disciplinary knowledge and the appropriate teaching processes that support student learning. A strong framework of validation based on multiple lines of evidence of the relationship between the items developed for the study and observations, analysis of video, and artifacts from the classroom is one element of the study. Another element of the study examines multiple psychometric lines of evidence to determine the reliability of the instruments and the validity of the inferences drawn from them. The resulting instruments will be used in the measurement of changes of teacher content knowledge for teaching in professional development programs as another source of validation.The improvement of teachers' content knowledge for teaching is an important intermediary goal of professional development of teachers. Without adequate understanding of the gaps in teacher knowledge and precise evidence of the improvement through professional development, the efficacy of different professional development projects is not possible. This project develops a model of teacher assessment instrument development that addresses a cross-cutting theme in the Next Generation Science Standards and contributes an important tool to the research and evaluation processes that are needed to make those standards a reality in the classroom. Findings from the use of the instruments across multiple projects inform policy decisions on local, state and federal levels.

该项目开发了一种工具来衡量教师需要在高中课堂教学中教授能源的内容知识，该教室专注于机械能量。有重大的研究表明，教师内容知识与其他专业中的人们需要了解的有关数学等特定领域的知识以及力学教学知识的发展是这些研发工作的扩展。该项目将仪器的开发嵌入了一项衡量课堂中物理学有效教学的计划中，并根据其在专业发展项目中用作衡量标准的评估，为由此产生的有效性论点，该论点旨在提高教师对物理学中的能量的理解。研究团队由物理，评估和课堂物理教学专家组成。该协作项目包括罗格斯，缅因州大学，西雅图太平洋大学，Facets Innovation和教育测试服务的研究人员。该项目使用一个框架来进行有效的教学框架，这些框架是在盖茨基金会资助的有效教学项目量度中开发的，以构建一个理论框架，以构建机械能源教学的理论框架。该框架包括基于课堂上的教学实践的项目和任务，这些项目和任务可以确定教师了解学科知识的程度和支持学生学习的适当教学过程。基于多种证据的验证框架的强大框架是为研究而开发的项目之间关系，视频分析和课堂工件之间的关系是研究的一个要素。该研究的另一个要素检查了多种心理测量线的证据线，以确定工具的可靠性和从中得出的推论的有效性。由此产生的工具将用于测量教师内容知识在专业发展计划中的教学知识的变化，作为验证的另一个来源。教师的内容知识的改善是教师专业发展的重要中介目标。如果没有足够的了解教师知识的差距和通过专业发展改善的精确证据，则无法实现不同的专业发展项目的功效。该项目开发了教师评估工具开发的模型，该模型涉及下一代科学标准中的横切主题，并为研究和评估过程做出了重要的工具，这些工具使这些标准在课堂上成为现实。跨多个项目的使用工具的发现为当地，州和联邦一级的政策决策提供了决定。
