What Is Distance Learning Technology?
By Jim

Teachers and counselors need to know: what is technology? They should be prepared to answer this question. Education is not confined to the classroom anymore and technologies allow students to decide where, when and how they want to study.

Types of Technology

Distance learning technology can be divided into four basic categories - print, audio, video and computer. Many of them overlap and combinations of these technologies may be used for some programs.

Print-based programs use text books, work books, study guides, fax, etc. Printed materials were used for correspondence courses, the original form of distance learning. Print still remains an important component of most programs.

Many new methods are now being used and before you select a course, try to learn a little about what is technology.

Audio-based programs use audio tapes, radio, audio conferences, the telephone, etc.

Video-based programs use satellite delivery, video tape, desktop video, broadcast video, microwave, etc.

Computer-based programs use CD-ROM, collaboration software, web-based software, video conferences and e-mail. Before signing-up for a computer-based program, find out what is technology.

Advantages and Disadvantages of Different Types of Technology

Printed materials are cost-effective, and can be used anywhere. They are easily available and learners are generally comfortable using them. However, they offer no interaction and there are no audio/visual elements. It takes time to deliver them and students require reading skills.

Audio-based methods are cheap, accessible and easy-to-use. The downside is that they lack visual information, need to be scheduled and tend to be impersonal.

Video-based programs offer both audio as well as video communication. They allow instructors and students to see body language, expressions, etc, and allow a higher level of interaction. The downside is that they require technical support and are expensive. They also need preparation, planning and scheduling.

Computer-based programs are inexpensive, allow students to move at their own pace and provide a high level of interaction. There is a written record and they can be accessed from anywhere. They offer graphics, text, audio and video. However, they often rely on written communication; need planning, a computer and an internet connection. There is also a danger of viruses and of computer network failure.

To select a suitable course, you need to know what is technology. Be sure to select a course which uses the technology that maximizes your learning experience.
