WHAT IS INSTRUCTIONAL TECHNOLOGY?It is hoped that the preceding discussion has managed to disclose and explicate the forces, issues, and prevailing views that characterize instructional technology. I have pointed out that the field may be viewed, first, as a set of professional people concerned with the development and use of instructional techniques having the purpose of promoting effective human learning. The learning with which these people are concerned may occur in the school, in the industrial classroom, in the specialized learning center, or in the home. Learning is often initiated and brought about by communications to the learner, and these communications are frequently delivered by equipment and its associated procedures, commonly referred to as media. Currently, these media include such "high-tech" items as television and computer systems in their various forms.
