This project aims to serve the national interest by improving teaching and learning in online laboratory environments in college physics courses. During the COVID-19 pandemic, many colleges and universities were forced to move traditionally face-to-face classes and labs to online formats. Because many typical lab experiences involve hands-on interaction with equipment, as well as demonstrations and close supervision by instructors, it is challenging to create online variations that teach the same concepts and skills and that meet individual students' needs. It is important for educators to understand whether remote lab experiences, which proliferated during the pandemic, are equitable, rigorous, comprehensive, and responsive to students' individual learning and social needs. This research will study those issues.This project will investigate how undergraduate physics instructors and students engage and perform in online laboratories. It will focus on the decision-making processes and implementation of teaching in an online learning environment from the perspective of instructors (faculty and graduate students), with a particular emphasis on laboratory instruction. The research will also explore the attitudes and academic performance of undergraduate physics students with regard to their lab experiences, including whether the students have differentiated experiences with respect to gender, ethnicity, or social class. The research will identify ways in which pedagogy in undergraduate science, students' performance in physics, and students' attitudes toward physics and online learning may be improved, particularly for students from groups that are underrepresented in STEM. Research questions will include the following:(1) How have physics faculty and graduate teaching assistants adapted laboratory course materials to transition to remote learning, and how are their pedagogical practices characterized in the online medium?(2) What factors influence their online teaching in terms of prior knowledge and training, peer collaboration, and external directives?(3) To what extent is online lab instruction characterized by technical, logistical, and pedagogical tensions, and how are these challenges formatively mitigated throughout the semester?(4) How are students' sociocognitive views of physics self-efficacy, self-concept, identity, epistemology, motivation, and career intentions influenced by participation in online physics instruction?(5) How is students' acquisition of physics knowledge and skills influenced by participation in online labs?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.

该项目旨在通过改善大学物理课程在线实验室环境中的教学和学习来服务于国家利益。在COVID-19大流行期间，许多学院和大学被迫将传统的面对面课程和实验室转移到在线形式。由于许多典型的实验室体验涉及与设备的动手交互，以及演示和教师的密切监督，因此创建在线变体来教授相同的概念和技能并满足个别学生的需求是具有挑战性的。对于教育工作者来说，重要的是要了解在大流行期间激增的远程实验室体验是否公平、严格、全面，并能满足学生的个人学习和社交需求。本研究将探讨这些议题，并探讨大学物理教师与学生如何参与线上实验室。它将侧重于从教师（教师和研究生）的角度在网上学习环境中的教学决策过程和实施，特别强调实验室教学。该研究还将探讨本科物理学生对实验室经验的态度和学习成绩，包括学生是否在性别、种族或社会阶层方面有不同的经验。该研究将确定本科科学教学法，学生在物理学方面的表现以及学生对物理和在线学习的态度可能得到改善的方法，特别是对于来自STEM代表性不足的群体的学生。研究问题将包括以下内容：（1）物理教师和研究生助教如何调整实验室课程材料过渡到远程学习，以及他们的教学实践特点是如何在网上媒体？(2)在先前的知识和培训、同伴合作和外部指令方面，哪些因素影响他们的在线教学？(3)在线实验教学在多大程度上具有技术、后勤和教学紧张的特点，以及如何在整个学期中形成性地缓解这些挑战？(4)学生的物理自我效能、自我概念、身份、认识论、动机和职业意向的社会认知观点如何受到参与在线物理教学的影响？(5)参与线上实验对学生物理知识与技能的习得有何影响？NSF IUSE：EHR计划支持研究和开发项目，以提高所有学生STEM教育的有效性。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
