The National Library of Medicine's National Center for Biotechnology Information offers mini-courses which entail applying concepts in biochemistry and genetics to search genomics databases and other information sources. They are highly interactive and involve use of 3D molecular visualization software that can be computationally taxing.
Methods were devised to offer the courses at a distance so as to provide as much functionality of a computer lab as possible, the venue where they are normally taught. The methods, which can be employed with varied videoconferencing technology and desktop sharing software, were used to deliver mini-courses at a distance in pilot applications where students could see demonstrations by the instructor and the instructor could observe and interact with students working at their remote desktops.
Student ratings of the learning experience and comments to open ended questions were similar to those when the courses are offered face to face. The real time interaction and the instructor's ability to access student desktops from a distance in order to provide individual assistance and feedback were considered invaluable.
The technologies and methods mimic much of the functionality of computer labs and may be usefully applied in any context where content changes frequently, training needs to be offered on complex computer applications at a distance in real time, and where it is necessary for the instructor to monitor students as they work.
美国国立医学图书馆的国家生物技术信息中心提供小型课程,这些课程需要应用生物化学和遗传学概念来搜索基因组数据库及其他信息源。它们具有高度的互动性,且涉及使用可能对计算要求较高的3D分子可视化软件。
设计了远程授课的方法,以便尽可能提供计算机实验室(通常授课的场所)的功能。这些方法可与各种视频会议技术和桌面共享软件一起使用,在试点应用中用于远程提供小型课程,学生可以观看教师的演示,教师可以观察在远程桌面工作的学生并与他们互动。
学生对学习体验的评分以及对开放式问题的评论与面对面授课时相似。实时互动以及教师从远程访问学生桌面以提供个别帮助和反馈的能力被认为非常宝贵。
这些技术和方法模仿了计算机实验室的许多功能,可有效应用于任何内容频繁变化、需要实时远程提供复杂计算机应用培训且教师需要在学生工作时进行监控的环境。
