INSTRUCTIONAL TECHNOLOGY

Although there are differing opinions about the nature of instructional technology, the Commission on Instructional Technology (1970) provided the following definition:
Instructional technology is a systematic way of designing, carrying out, and evaluating the total process of learning and teaching in terms of specific objectives, based on research in human learning and communication, and employing a combination of human and nonhuman resources to bring about more effective instruction. (p. 199)
Typical applications of instructional technology may use conventional media such as videotapes, computer assisted instruction, or more complex systems, such as hypermedia programs in which computers are used to control the display of audio and visual images stored on videodisc (Blackhurst & Morse, 1996), CD-ROM and digital video discs. The use of telecommunication systems, particularly the Internet (Williams, 1995) and its World Wide Web component (Williams, 1996), have great promise for use in classrooms and for distance education. Computer software systems are now available that can be used to manage the delivery of instruction via the Web. Such systems have been used successfully to deliver instruction to undergraduate and graduate students on topics related to special education (Blackhurst, Hales, & Lahm, 1997).
