Understanding the complex relationships among teaching, course environments, and student learning is important to inform improvements in science, technology, engineering, and mathematics (STEM) education. This project aims to serve the national interest by studying the connections between several aspects of inorganic chemistry instruction and college students’ learning about molecular-level symmetry, a concept that is essential for understanding how three-dimensional structures influence the properties of substances. Currently, little is known about how instructors teach about symmetry or how students use their understanding of it to solve problems. This project plans to collect and analyze data from inorganic chemistry courses around the country to characterize teaching practices, course environments, and their connections to student learning. The results of this work will be used to develop evidence-based professional development materials for inorganic chemistry instructors to enhance student learning about molecular-level symmetry.The project will be conducted by a collaborative research team from the University of North Carolina at Greensboro and the University of Wisconsin–Madison. The project team will employ the Consensus Model of Teacher Professional Knowledge, which positions the relationship between instruction and learning within a framework of multiple factors, such as instructor and student beliefs, behaviors, and knowledge. Faculty and student research participants will be recruited from twenty-six inorganic chemistry courses from a variety of institution types across the nation. The research questions to be addressed include: (1) How do the teaching beliefs of inorganic chemistry instructors impact their classroom practices when teaching symmetry? (2) How do classroom practices for teaching symmetry emerge from the mutual bootstrapping of personal pedagogical content knowledge (PCK), PCK & skill, and classroom context? (3) How can student outcomes for symmetry be traced to classroom practices? (4) How can student amplifiers and filters explain different student outcomes across different sets of classroom practices? and (5) What constitutes topic-specific professional knowledge for teaching symmetry? To address these research questions, the project team plans to conduct multiple embedded case studies using convergent mixed methods. A variety of quantitative and qualitative data streams will inform each case. Data sources will include interviews with faculty members and students, video observations of symmetry instruction, course artifacts, and student learning and skills assessments. In constructing each case, the project team will use a combination of inductive and deductive coding methods to analyze qualitative data prior to integrating with quantitative data. An expert advisory panel will monitor the success of the project and provide important feedback at specific decision-making points. The results of this project will be disseminated to researchers and educators via workshops, conference presentations, and journal publications. The project is expected to advance our understanding of the learning and teaching of symmetry, as well as various instruction-learning relationships. Thus, the findings will have potential to improve undergraduate chemistry education and will be of interest to education researchers from a variety of STEM disciplines. The NSF IUSE: EHR Program supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

了解教学、课程环境和学生学习之间的复杂关系对于科学、技术、工程和数学 (STEM) 教育非常重要。该项目旨在通过研究无机化学教学的多项改进之间的联系来服务于国家利益。以及大学生对分子水平对称性的学习，这一概念对于理解三维结构如何影响物质的性质至关重要。目前，人们对教师如何教授对称性或学生如何利用他们对对称性的理解来解决问题知之甚少。该项目计划收集和分析数据。这项工作的结果将用于为无机化学教师开发基于证据的专业发展材料，以增强学生对分子水平的学习。该项目将由北卡罗来纳大学格林斯博罗分校和威斯康星大学麦迪逊分校的合作研究小组进行。该项目小组将采用教师专业知识共识模型，该模型将教学与学习之间的关系定位在内部。多重因素的框架，教师和学生的研究参与者将从全国各地不同类型的机构的 26 个无机化学课程中招募。要解决的研究问题包括：（1）如何做。无机化学教师的教学信念在教授对称性时影响他们的课堂实践？（2）对称性教学的课堂实践如何从个人教学内容知识（PCK）、PCK 和技能以及课堂环境的相互引导中产生？怎么可以学生的对称性成果可以追溯到课堂实践吗？（4）学生放大器和过滤器如何解释不同的课堂实践中的不同学生成果？（5）什么构成了对称性教学的特定主题专业知识？ ，项目团队计划使用聚合混合方法进行多个嵌入式案例研究，每个案例的数据源将包括对教师和学生的访谈、对称教学的视频观察、课程工件和。学生的学习和技能评估。在构建每个案例时，项目团队将结合归纳和演绎编码方法来分析定性数据，然后与定量数据集成。专家顾问小组将监控项目的成功并在特定决策点提供重要反馈。该项目的结果将通过研讨会、会议演讲和期刊出版物传播给研究人员和教育工作者，该项目预计将增进我们对对称性的学习和教学以及各种教学与学习关系的理解。研究结果将有可能改善本科化学教育来自各个 STEM 学科的教育研究人员都会感兴趣 NSF IUSE：EHR 计划支持研究和开发项目，以提高所有学生的 STEM 教育的有效性，该计划支持创造和探索。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
