EXP: RUI: Exploring Spatial-Temporal Anchored Collaboration in Asynchronous Learning Experiences

该项目的研究人员正在开发和研究一个基于网络的多媒体平台，该平台将允许特殊时间的注释，用于高等教育课程的协作。数字网络媒体的使用在高等教育环境中变得越来越普遍和重要。教师通常会发布大量的图片、音频剪辑和视频供学生使用。随着教师不断采用创新的教学方法，使用这些多媒体材料，在典型的课堂设置之外，在线提供多媒体内容的需求变得更加重要。混合、远程学习和大规模开放在线课程对数字媒介内容的交付提出了额外的要求。目前针对大量教育媒体的托管解决方案缺乏工具来促进丰富的协作话语和社交学习。学生与学生之间的互动在面对面的环境中是微不足道的，在网络环境中不容易复制。在某种程度上，这是由于在媒体播放系统中缺乏对时空协作的支持。为了解决这些限制，本项目探索了新技术的实现，以支持各种网络托管媒体（包括视频、音频和静止图像）的时空协作。研究人员将设计、部署和评估TrACE——变革性锚定协作环境。该项目更广泛的影响在于，它可能会改变异步环境下教育内容的处理方式——尤其是大规模开放在线课程（MOOCs）。mooc有望改变本科教育，使传统上代表性不足的人群也能获得本科教育。

The researchers on this project are developing and studying a web-based multi-media platform that will allow special-temporal annotations intended for collaboration in post-secondary courses. The use of digital web-hosted media is becoming increasingly commonplace and important in postsecondary educational environments. Instructors routinely post large collections of images, audio clips, and videos for student use. As instructors continue to adopt innovative pedagogies using these multi-media materials, the need to deliver multimedia content online, outside of the typical class setting, becomes even more important. Hybrid, distance learning, and massive open online courses place additional demands on the delivery of digitally-mediated content.Current hosting solutions for the large amount of educational media lack tools to foster rich collaborative discourse and social learning. Student-to-student interactions that would be trivial in face-to-face settings are not easily reproduced in online environments. In part this is due to the lack of support for spatial-temporal collaboration within media playback systems. In order to address these limitations, this project explores the implementation of novel techniques to support spatial-temporal collaboration over a variety of web-hosted media including video, audio, and still images. The researchers will design, deploy, and evaluate TrACE - the Transformative Anchored Collaboration Environment.The broader impact of the project lies in the potential transformation of how educational content is addressed in asynchronous environments - in particular massive open online courses (MOOCs). MOOCs have the promise of transforming undergraduate education making it available to traditionally underrepresented populations.
