This project investigates educators' understanding of concepts involved in applying telecommunications networks to educational purposes. The investigators will develop a prototype series of videotaped information on the NSFNET, Internet and NREN. Telecommunications is a dynamic and procedural subject. To understand the networks, educators need to see demonstrations of network applications and animated sequences that illustrate data/message exchange and transmission across systems. The content will include basic concepts of networking, how networks are used in education, characteristics of NSFNET/Internet, and how to use the NSFNET. An experimental feature of the video series will be a scenario-based viewers assessment. Viewers will be asked to assess their level of understanding after viewing the video; sequences. This information will be used to identify requirements for more extensive educational materials on this subject for educators.

本项目调查教育工作者对将电信网络应用于教育目的所涉及的概念的理解。研究人员将在NSFNET、互联网和NREN上开发一系列录像信息的原型。电信是一门动态的、程序性的学科。为了理解网络，教育工作者需要看到网络应用的演示和演示跨系统的数据/消息交换和传输的动画序列。内容将包括网络的基本概念、网络如何在教育中应用、NSFNET/Internet的特点以及如何使用NSFNET。该视频系列的一个实验性特征将是基于场景的观众评估。观众将被要求在观看完视频后评估自己的理解水平；序列。这些信息将用于确定是否需要为教育工作者提供关于这一主题的更广泛的教育材料。
