Technology Based Evaluation of Classroom Learning

这项研究将探讨使高中和大学教师能够通过对通过基于技术的教室仪器收集的数据进行自动分析来评估他们的学生学习情况的可行性。这些数据将包括关于互动课堂行为的音频/视频集合，这些行为与既定的成绩标记有关。数据收集的结果将被整合到DVD演示文稿中，该演示文稿将为教师提供反馈，以便进行自我评估，并有机会自我完善，或纳入指导指导系统。这一努力将建立在三个不同研究团体之前的努力之上：教育、军事情报和互联网技术。这项研究将推进视频处理，重点是与教室相关的自动行为模式分析。它还将增加对以前开发的用于帮助教师改进的手动教室观察指标与从一系列教室传感器收集的相应指标之间的关系的理解。这项工作的开展将导致在将音频/视频技术应用于课堂监控和教师自我改进方面取得尚未被考虑的进展，并开启关于课堂设置的创新研究路线。拟议的努力在弗吉尼亚大学启动了一项新的重要研究合作，将致力于改善教学与学习中心教育的研究人员与致力于先进无线传感器技术未来应用的研究人员在无线互联网先进技术中心(NSF赞助的产学合作研究中心)的工作结合在一起。这种合作被认为是推动以技术为基础的课堂评估概念的重要因素。如果成功，这一努力无疑将催生各种机会，改进最初的概念，并相应开发新的生产系统。

This research will address the feasibility of enabling teachers at the high school and college levels to evaluate how well their students are learning via an automated analysis of data collected through technology-based instrumentation of their classrooms. The data will include audio/video collections on interactive class room behaviors, which are related to established performance markers. Results of data collections will be integrated into a DVD presentation that will produce feedback for the teacher for self-evaluation with the opportunity for self-improvement, or incorporation into guided coaching systems. The effort will build upon prior efforts from three different research communities: education, military intelligence, and Internet technology. This research will advance video processing that focuses on automated behavior pattern analysis related to a class room. It will also increase understanding of the relationship between previously developed manual class room observation metrics for helping teachers to improve and corresponding metrics gathered from an array of class room sensors. The conduct of this work will lead to identification of yet to be considered advances in the application of audio/video technology to classroom monitoring and teacher self improvement as well as the opening of innovative lines of research on classroom settings.The proposed effort initiates a new and important research collaboration at the University of Virginia integrating the work of researchers who have been engaged in improving education at the Center for Advanced Study of Teaching and Learning and researchers who have been engaged in future applications of advanced wireless sensor technology at the Wireless Internet Center for Advanced Technology, an NSF sponsored Industry/University Cooperative Research Center. This collaboration is considered to be an important element in advancing the concept of technology-based class room evaluation. If successful, this effort will undoubtedly spawn a variety of opportunities for improvement of the initial concept and the corresponding development of new production systems.
