摘要

对409个远程教育网站进行了内容分析,以评估他们对在线课程中使用的媒体的解释。通过检查课程演示、视频介绍、与“学术”相关的页面、与常见问题(FAQ’s)相关的页面以及分析课程提供的文本描述,我们完成了一份由16种媒体策略组成的检查表。Holsti的信度系数显示,三个分析师之间的互码一致性为85.3%。只有67所大学提到使用7种或更多的媒体类型,90所大学被发现是有电子邮件支持的函授课程。以文本为基础的媒体(电子邮件和以印刷为基础的讨论板)被认为是通信和信息交换的主要方法。许多网站提到了流媒体视频、在线会议或同步讲座等尖端互联网技术,但各机构并没有在其网站上有效地传达如何使用这些技术来支持教学。

The Part Played by Instructional Media in Distance Education
A content analysis of 409 distance education web sites was conducted to assess their explanations of the media used in their online course offerings. A check sheet consisting of sixteen media strategies was completed for each by examining course demonstrations, video introductions, pages related to “Academics,” pages related to Frequently Asked Questions (FAQ's) and by analyzing text descriptions of course offerings. Holsti's reliability coefficient showed an 85.3% intercoder agreement among three analysts. Only 67 universities mentioned using seven or more media types and 90 were found to be correspondence courses with email support. Text- based media (e-mail and print-based discussion boards) were mentioned as being the primary method of communication and information exchange. Many of the sites mentioned cutting-edge internet technologies such as streaming video, online conferencing or synchronous lectures, but institutions do not effectively communicate on their websites how these technologies are used to support instruction.
