Collaborative Project: Physics Teaching Web Advisory (Pathway)--A Digital Video Library for Physics Teaching

本项目为与卡内基梅隆大学合作项目（奖励号0226219）。研究人员正在为物理教学创建一种新型数字图书馆的概念验证演示。该项目汇集了数字视频图书馆、先进远程学习技术和协作技术方面的几个长期研究项目，以及国内知名的物理教学法专家和高质量的内容。该项目建立在卡内基梅隆大学的Informedia数字视频图书馆（参见NSF奖励号9411299,9817496和0085834）的基础上，该图书馆正在解决从视频和音频内容中提取信息的问题，以及对物理大师教师的“综合访谈”。综合面试技术创造了一个拟人化的界面，进入一个人回答问题的视频中。基于几位物理大师的视频的综合访谈将使教师能够与知识渊博的专家就他们的课堂技巧以及这些技巧如何与物理教学中的当代问题相关联进行交谈。教师还可以创建个人综合访谈，除了为其他教师提供资源外，还可以成为学生的虚拟“随时随地”导师。该项目旨在建立一个最先进的系统，通过该系统，教师可以与物理教学专家进行虚拟和直接的互动，合作帮助彼此成为更有效的物理教师，并为学生开发高级课程。

This is a collaborative project with Carnegie Mellon University (Award No. 0226219).The investigators are creating a proof-of-concept demonstration of a new type of digital library for physics teaching. The project brings together several long-standing research projects in digital video libraries, advanced distance learning technologies, and collaboration technologies, and nationally known experts in physics pedagogy and high-quality content.The project builds on Carnegie Mellon University's Informedia Digital Video Library (see NSF Award Nos. 9411299, 9817496, and 0085834), which is addressing the problem of information extraction from video and audio content, and "synthetic interviews" of master physics teachers. Synthetic interview technology creates an anthropomorphic interface into video of a person responding to questions. Synthetic interviews based on videos of several master physics teachers will allow teachers to converse with knowledgeable experts about their classroom techniques and about how those techniques are related to contemporary issues in physics teaching. Teachers will also be able to create personal synthetic interviews, which, in addition to providing a resource for other teachers, can become a virtual, "anytime, anywhere" tutor for students.The project aims to produce a state-of-the-art system through which teachers can interact, both virtually and directly, with experts in physics teaching, cooperate to help each other become more effective teachers of physics, and develop advanced courses for their students.
