Collaborative Research: The Impact of LivePhoto Physics Materials and Workshops

物理学（13）.该项目遵循美国国家科学基金会支持的LivePhoto物理项目，并扩大了LivePhoto物理团队，它承担了一个为期四年的合作研究项目：（A）组织一个国家专业发展计划，其中包括为学院和大学教职员工举办的六个讲习班，旨在帮助参与者学习如何在讲座和实验室环境中有效地使用数字视频捕获和分析;（B）在几个机构利用基于视频的课堂、实验室和家庭作业活动，对学生的学习和态度进行研究，包括研究学生对物理专题的概念理解，他们对事件、图形和方程之间关系的理解，以及他们使用分析数学建模的能力;及（C）审核工作坊参与者在教学方法上的改变，以及受工作坊影响的学生的特点和人数，以评估项目的整体影响。智力优势：物理教育研究（PER）社区的一个主要发现是，学生不能获得物理的功能性理解，除非他们掌握物理学家用来描述物理现象的多种表示以及这些表示之间的关系。对视频分析的初步研究表明，它可以增强学习，帮助学生掌握真实的物理现象，数字视频帧，数据表，图形和分析方程之间的关系。扩大的LivePhoto物理团队正在研究：（1）专业发展研讨会对教师后续实践的影响，以及（2）当教师将数字视频分析与LivePhoto物理课程材料结合使用时，对学生学习的影响。更广泛的影响：为144名教师提供专业发展机会。有些教授其他基础科学的入门课程，如生物学，化学或数学。预计将有43 000多名学生直接受到该项目期间教员参与者所促成的变化的影响，今后将有更多的学生通过这些参与者的传播受到影响。该项目正在增加数字视频分析在帮助学生掌握困难的物理课题中的作用的研究主体，使用全方位的表示，包括分析数学建模。招聘计划的目标是那些教授传统上代表性不足的学生群体的教师。

Physics (13). This project follows the NSF supported LivePhoto Physics Project and expands the LivePhoto Physics team, It undertakes a four-year Collaborative Research Project to: (A) Organize a National Professional Development Program that includes six workshops for college and university faculty members designed to help participants learn how to use digital video capture and analysis effectively in lecture and laboratory settings; (B) Conduct research on student learning and attitudes based on the use of video-based classroom, laboratory, and homework activities at several institutions and include studies on students' conceptual understanding of physics topics, their understanding of the relationship between events, graphs and equations, and their ability to use analytic mathematical modeling; and (C) Evaluate the overall project impact by conducting an audit of the changes in the teaching practices of workshop participants and the characteristics and number of students affected by the workshops. Intellectual Merit: A major finding in the Physics Education Research (PER) community is that students cannot acquire a functional understanding of physics unless they master the multiple representations that physicists use to describe physical phenomena and the relationship between these representations. Preliminary research on video analysis suggests it enhances learning and helps students master relationships between real physical phenomena, digital video frames, data tables, graphs, and analytic equations. The extended LivePhoto Physics team is studying: (1) the impact the professional development workshops have on the subsequent practices of instructors, and (2) the impact on student learning when instructors use digital video analysis in conjunction with LivePhoto Physics curricular materials that have been designed using principles developed by PER. Broader Impact: Professional development opportunities are provided for 144 faculty. Some teach introductory courses in other basic sciences such as biology, chemistry, or mathematics. Over 43,000 students are expected to be directly affected by the changes fostered in faculty participants during this project, and many more will be affected in later years through dissemination by these participants. The project is adding to the body of research on the role of digital video analysis in helping students master difficult physics topics using a full range of representations including analytic mathematical modeling. The recruitment program targets faculty members who teach traditionally under-represented groups of students.
