LivePhoto Physics: Digital Videos for Lectures and Assignments

物理（13）LivePhoto Physics项目正在为物理入门课程开发一套数字视频分析材料，采用基于研究的开发方法，这些方法是通过诸如科学思维工具和车间物理等项目改进的。这些材料包括视频，讲座演示序列，家庭作业，讲师笔记和软件。在数字视频分析中，学生使用计算机作为实验室仪器对真实事件的视频图像进行测量。这些技术越来越多地用于物理课程，有证据表明它们在教授物理概念方面是有效的。尽管有大量的大众媒体和教育视频可用于实验室或学生项目，但很少有现有的视频是学生分析的理想选择。LivePhoto物理项目通过制作一系列数字视频来满足这一需求，这些视频涵盖了一年物理课程中的许多主题，包括使用大多数教学设施无法提供的高速/慢动作设备制作的视频。该项目的创新之处在于，选题以物理教育研究成果为指导。在一个以研究为基础的三年开发周期中，正在制作和课堂测试使用视频互动讲座演示、远程学习练习和扩展的家庭作业问题集的书面课程材料。实地测试在两年制学院和四年制学院/大学进行，有不同的学生受众。在该项目期间，正在开发扩展数字视频分析的显示和可视化能力的计算机软件。最后一套视频、课程材料和软件将以CD的形式出版。LivePhotoPhysics项目通过赞助六次关于在物理教学中使用数字视频分析的研讨会，解决了教师发展和教育技术整合的需求。

Physics (13) The LivePhoto Physics project is developing a collection of digital video analysis materials for introductory physics courses, using research-based developmentmethods that were refined through projects such as Tools for Scientific Thinkingand Workshop Physics. These materials include videos, lecture demonstrationsequences, homework assignments, instructor notes, and software. In digital videoanalysis, students use computers as laboratory instruments to make measurementson video images of real events. These techniques are being used increasingly inphysics courses, and there is evidence that they are effective in teaching physicsconcepts. In spite of the wealth of mass-media and educational videos available thatcan be used in laboratories or student projects, very few existing videos are ideal foranalysis by students. The LivePhoto Physics project ismeeting this need by producing a collection of digital videos that span many of thetopics covered in a one-year physics course, including videos made with high-speed/slow-motion equipment that is not available at most teaching facilities. Aninnovative aspect of the project is that the topic selection is being guided by theresults of physics education research. Written curricular materials using the videosin Interactive Lecture Demonstrations, distance-learning exercises and extendedhomework problem sets are being produced and classroom tested in a three-yearresearch-based development cycle. Field testing is taking place at two-year collegesand four-year colleges/universities with diverse student audiences. Computersoftware that extends the display and visualization capabilities of digital videoanalysis is being developed during the project. The final set of videos, curricularmaterials and software will be published in the form of a CD. The LivePhotoPhysics project is addressing the need for faculty development and the integration oftechnology in education by sponsoring six workshops on the use of digital videoanalysis in physics teaching.
