This project seeks to serve the national interest by developing tools to better understand and improve college students’ reasoning skills in the context of chemistry and physics courses. Despite decades of work aimed at improving students’ science learning by developing and implementing research-based instructional materials, emerging evidence suggests that students who demonstrate correct conceptual understanding and reasoning on one task often fail to reason productively on analogous tasks that require the same knowledge and skills. The persistence of such reasoning difficulties after instruction is concerning since the development of reasoning skills is possibly one of the most important outcomes of college instruction in the physical sciences. However, many existing research-based assessments for physics and chemistry do not provide sufficient insight into student reasoning approaches because they were not designed to disentangle reasoning from conceptual understanding. This project seeks to address this challenge by developing and disseminating online reasoning chain construction assessment (ORCCA) tools and instructor guides designed to be incorporated into college-level physics and chemistry courses. The project team will also use the assessment tools developed to conduct research to better understand student reasoning about chemistry and physics.In this project, a research team from four institutions (North Dakota State University, University of Maine, Penn State University - Greater Allegheny, and University of North Florida) will examine and seek to improve student reasoning by developing online reasoning chain construction assessment (ORCCA) tools for physics and chemistry courses. Drawing upon dual-process theories of reasoning, researchers have found that reasoning inconsistencies often stem from the interplay between human reasoning tendencies and relevant discipline-specific knowledge and skills. Online reasoning chain construction assessment tools present students with reasoning elements, i.e., statements about the physical situation as well as related concepts and mathematical relationships, and prompt the students to assemble them into an argument to answer a target question that often elicits incorrect intuitive responses. This project will focus on introductory physics, general chemistry, and organic chemistry courses, and will: (1) develop, refine, and disseminate ORCCA tools; (2) develop, refine, and disseminate screening-target question pairs that provide measures of both disciplinary knowledge and the reasoning skills necessary to apply that knowledge consistently; (3) generate cross-disciplinary knowledge about student reasoning; and (4) develop instructor guides for the use of ORCCA tools and screening-target pairs for both assessment and instruction. The project will employ a mixed-methods sequential exploratory design, leveraging both qualitative and quantitative analyses, and will draw upon a variety of experimental techniques and frameworks from cognitive science. Dissemination will include publications of results in scientific journals, workshops at national meetings, online access to assessment tools and instructor resources, and individualized support for pilot sites in implementing ORCCAs. 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.

该项目旨在通过开发工具来更好地理解和提高大学生在化学和物理课程背景下的推理技能，以服务于国家利益。尽管几十年来致力于通过开发和实施研究型教学材料来改善学生的科学学习，但新出现的证据表明，在一项任务上表现出正确的概念理解和推理的学生，往往无法在需要相同知识和技能的类似任务上进行富有成效的推理。这种推理困难在教学后的持续存在令人担忧，因为推理技能的发展可能是大学物理教学最重要的成果之一。然而，许多现有的基于研究的物理和化学评估并没有提供对学生推理方法的足够洞察力，因为它们不是为了将推理与概念理解分开而设计的。该项目旨在通过开发和传播在线推理链构建评估(ORCCA)工具和教师指南来应对这一挑战，这些工具和教师指南旨在纳入大学级的物理和化学课程。在这个项目中，一个来自四个机构(北达科他州立大学、缅因州大学、宾夕法尼亚州立大学-大阿勒格尼大学和北佛罗里达大学)的研究团队将通过开发用于物理和化学课程的在线推理链构建评估(ORCCA)工具来检查和寻求改善学生推理能力。利用推理的双过程理论，研究人员发现，推理的不一致性往往源于人类的推理倾向和相关学科特定知识和技能之间的相互作用。在线推理链构建评估工具向学生呈现推理元素，即关于物理情况的陈述以及相关概念和数学关系，并提示学生将它们组合成一个论点来回答经常引起不正确直觉反应的目标问题。本项目将集中于物理、普通化学和有机化学入门课程，并将：(1)开发、提炼和传播ORCCA工具；(2)开发、提炼和传播筛选目标问题对，提供学科知识和持续应用知识所需的推理技能的测量；(3)生成关于学生推理的跨学科知识；以及(4)开发教师指南，以使用ORCCA工具和筛选目标对进行评估和教学。该项目将采用混合方法顺序探索性设计，利用定性和定量分析，并将借鉴认知科学的各种实验技术和框架。传播将包括在科学期刊上发表成果，在国家会议上举办讲习班，在线获取评估工具和教师资源，以及为实施ORCCA的试点地点提供个性化支持。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。通过参与的学生学习路径，该计划支持有前景的实践和工具的创建、探索和实施。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
