Delivering Distance Education
A wide range of technological options, i.e., voice, video, internet and print, are available to the distance educator.
Voice - Instructional audio tools include the interactive technologies of telephone, audio conferencing, and short-wave radio.
Passive (i.e., one-way) audio tools include tapes and radio.
Video - Instructional video tools include still images such as slides, pre-produced moving images (e.g., film, videotape), and live video conferencing combined with one-way or two-way audio conferencing.
Internet - the largest, most powerful computer network in the world, encompasses more than 2 million computers with Internet addresses that are used by millions of people in more than fifty countries. As more and more colleges, universities, schools, companies, and private citizens connect to the Internet either through affiliations with regional not-for-profit networks or by subscribing to information services provided by for-profit companies, more possibilities are opened for distance educators to reach students including:
- Computer-assisted instruction (CAI) - uses the computer as a self-contained teaching machine to present individual lessons
- Computer-managed instruction (CMI) - uses the computer to organize instruction and track learners records and progress. The instruction itself need not be delivered via a computer, although CAI is often combined with CMI.
-Computer-mediated education (CME) - describes computer applications that facilitate the delivery of instruction. Examples include electronic mail, fax, real-time computer conferencing, and World-Wide Web applications. Print Various print formats are available including: textbooks, study guides, workbooks, course syllabi, and case studies.
