Reiser: History of Instructional Design and Technology

1. How is the term instructional media defined in this chapter? Why are teachers chalkboards, and textbooks excluded from the definition?

The term instructional media has been defined as the physical means via which instruc­tion is presented to learners (Reiser & Gagnt. 1983) Teachers chalkboards and textbooks were the three primary means of instruction before the twentieth century. To clearly describe the history of media, these three means are excluded.

2. Describe one way in which each of the following events or movements are related to current ideas or practices associated with instructional media.

School Museums: Museums served as the central administrative units for visual instruction by dis­tribution of portable museum exhibits, stereographs, slides, films, study prints, charts, and other instructional materials.

After this exhibitions are spread, a number of professionals rebelled against the notion that the books are only information presenters and they indicated that teachers should be viewed on an equal footing with instructional media, as just one of many possible means of presenting in­struction, and teachers should not be given sole authority for deciding what instruc­tional media will be used in classrooms.

The Audiovisual Instruction Movement: Researchers thought that Audiovisual materials were valuable for their ability to present concepts in a concrete manner. They thought radio would revolutionize education. But unfortunately radios and audiovisual materials didn’t have much impact on education

World War II: War forced people to learn and adapt quickly and a wide variety of other audiovisual materials and equipment were employed in the military forces and in industry during World War II. Devices that were used extensively included overhead projectors, which were first produced during the war; slide projectors, which were used in teaching aircraft and ship recognition: audio equipment, which was used in teaching foreign languages: and simulators and training devices, which were employed in flight training (Olsen & Bass, 1982. Saettler, 1990).

Post World War II Developments: The audiovisual devices helped to train a lot of people in a short time during the war and it gained a lot of attention. A lot of media researchers conducted a research and reached a conclusion that students learn equally well in both live instructed lessons and other media resources. Some have argued that researchers should focus on the attributes of media (Levie & Dickie, 1973), others have suggested an examination of how media influence learning (Kozma, 1991, 1994), and others have suggested that the research focus should be on instructional methods, rather than on the media that de­liver those methods (Clark, 1983, 1994).

Communication Theories: To give the most information in most effective way, a lot of theories were studied to make communication process better.

3. Many who have examined the history of instructional media have noted that as each new medium comes along, history repeats itself. Does this notion seem to apply to instructional films, instructional television and computers? If so, in what way(s) does it apply?

It has been noted that as each new medium comes along, history repeats itself. This notion applies to instructional films, television and computers (until 1995) because at first, these instructional medias seemed to facilitate learning to a great extent; yet, they all eventually had short lives and also had minimal impact on educational practices. The reason why their impacts on instructional practices faded in the course of time was the fact that they had learners interact with only instructional content, NOT with their instructor and learners.

4. Describe one way in which each of the following events or movements are related to current ideas or practices associated with the field of instructional design:

World War II: During the war, a large number of psychologists and educators who had training and experience in conducting experimental research were called on to conduct research and develop training materials for the military services. These individuals exerted considerable influence on the characteristics of the training materials that were developed, basing much of their work on instructional principles derived from research and theory on instruction, learning and human behaviour.

The Programmed Instruction Movement: In 1954, B.F. Skinner’s article entitled The Science of Learning and Art of Teaching began a minor revolution in the field of education. Skinner described his ideas about the requirements for increasing human learning and the desired characteristics of effective instructional materials.

The Behavioral Objectives Movement: In 1962, Robert Mager, wrote Preparing Objectives For Programmed Instruction. The book describes how to write objectives that include a description of desired learner behaviours,the conditions under which the behaviours are to be performed and the standards by which the behaviors are to be judged. Many present day adherents of the instructional design process advocate the preparation of objectives that contain these three elements.

The Criterion-referenced Testing Movement: One of the important development of the instructional design process is the emerge of criterion referenced testing. Until that time, most test called norm referenced test were designed to spread out the performance of learners. In contrast the criterion referenced test is intended to measure how well an individual can perform a particular behavior or a set of behaviors.

The Work of Robert M. Gagné: An important event in history of instructional design is the publication of the first edition of The conditions of Learning, written by Robert M. Gagne. In this book, Gagne described five domains of learning outcomes-verbal information, intellectual skills, psychomotor skills, attitudes and cognitive strategies- each of which required a different set of conditions to promote learning. Gagne also provided descriptions of these conditions for each type of learning.

The Launching of Sputnik: In 1957, when the Soviet Union launched Sputnik, the first orbiting space stellite, a series of events began that would eventually have a major impact on instructional design process. The U.S government shocked by the success, responded by pouring millions of dollars into improving math and science education in the United States. The instructional materials that were developed with these funds were usually writ­ten by subject matter experts and produced without tryouts with learners. Years later, in the mid- I960s, when it was discovered that many of these materials were not particularly effective, Michael Scriven (1967) pointed to the need to try out drafts of instructional ma­terials with learners before the materials were put in their final form. This process would enable educators to examine the materials and, if necessary, revise them while the mate­rials were still in their formative stases. Scriven termed this tryout and revision process formative evaluation and contrasted it with what he labeled summative evaluation, the testing of instructional materials after they are in their final form.

5. During the 1970s and 1980s, interest in instructional design grew in some sectors and diminished or had had little impact in others. Describe how interest in instructional design waxed and/or waned in the following sectors during the 1970s and 1980s.

Academia: In academia, many instructional improvement cen­ters were created during the first half of the decade with the intent of helping faculty use media and instructional design procedures to improve the quality of their instruction (Gaff. 1975; Gustafson & Bratton, 1984). Moreover, many graduate programs in instructional design were created (Partridge & Tennyson, 1979; Redfield & Dick. 1984; Silber. 1982).

Business and Industry: In business and industry, many organizations, seeing the value of using instructional de­sign to improve the quality of training, began adopting the approach (cf. Mager, 197: Miles, 1983).

The U.S. Military: In 1975, several branches of the U.S. military adopted an instructional design model (Branson et al, 1975) that was intended to guide the development of train­ing materials within those branches.

The International Arena: Internationally, many nations, such as South Korea. Liberia. and Indonesia, saw the benefits of using instructional design to solve instructional problems in those countries (Chadwick. 1986; Morgan, 1989). These nation- supported the design of new instructional programs, created organizations to support the use of instructional design, and provided support to individuals desiring training in this field. Many of these devel­opments were chronicled in the Journal of Instructional Development, a journal that was first published during the 1970s and that was the forerunner to the development section of Educational Technology Research and Development.

Public Education in the United States: In the public school arena, some cur­riculum development efforts involved the use of basic instructional design processes (e.g., Spady, 1988), and some instructional design textbooks for teachers were produced (e.g., Dick & Reiser, 1989: Gerlach & Ely, 1980; Sullivan & Higgins, 1983). However, in spite of these efforts, evidence indicated that instructional design was having little impact on instruction in the public schools (Branson & Grow, 1987; Burkman, 1987b; Rossett & Garbosky, 1987).
