Chapter 1
The Nature of Technology: The term technology is derived from the ancient Greek word techne. The term can be translated to refer to art, craft or skill. Plato viewed techne and systematic or scientific knowledge as being closely related. Aristotle went a step further by asserting that techne was the systematic use of knowledge for intelligent human action. In modern times, it is important to remember that technology is a system of practical knowledge that is not necessarily conditional on things or hardware. Bernard Gendron (1977) broadened the definition of technology by stating: "technology is any systematized practical knowledge, based on experimentation and/or scientific theory, which enhances the capacity of society to produce goods and services, and which is embodied in productive skills, organization, or machinery." Emergence of Educational Technology: Over time, diversity in educational technology (ET) has been affected by each significant shift in educational values, goals or objectives. Historically, the emphasis has been on establishing ET as a process rather than a product. Many individuals influenced the field of ET prior to this century:
* Johann Comenius (17th century): inventor of modern programmed instruction - used printed book to organize subject matter and teach several hundred students concurrently;
* John Locke (17th century): precursor of modern behavioral modification - tabula rasa theory, shift in concept of education from mental discipline to habit formation;
* Jean Jacques Rousseau (1712-1778): instructional method follows natural stages of human development. Proposed using appropriate technology to fit each stage.
* Johann Friedrick Herbert (1777-1841): first systems approach based on the four-step learning design;
* Maria Montessori (1870-1952): emphasized the individual learner, freedom and sensory education;
* James Sully (1842-1923): published book on the function of science in the teaching process. Viewed teaching as a technological process and instruction as both an art and science. Definitions of Educational Technology: Donald Ely distinguishes between the physical science (products = devices and equipment) and the behavioral science (process = knowledge and skills) components of ET. Heinich, et al. defined instructional technology "as the application of our scientific knowledge about human learning to the practical tasks of teaching and learning."

Paradigms of Educational Technology:

In ET, paradigms have traditionally defined how members of the field think, see, feel, and act with reference to the instructional problems they encounter. Paradigm shifts: science advances by revolutionary changes, not by the steadfast accumulation of experiences and observations. In this century, the following four major paradigm shifts have emerged in ET.

1. Physical Science or Media Approach to Educational Technology
* Applies physical sciences and engineering technology (equipment) in the presentation of materials or programs.
* Preoccupied with effects of devices and procedures vs. individual learners or selection/design of instructional content.
* Views non-verbal (graphics, film, television, etc.) as more effective than verbal (lectures, books).
* Flourished in the first half of this century, began to fade in 1960s.

2. Audiovisual Communications: A Synthesis of Communications and Systems Concepts
* Communications approach altered the traditional theoretical framework of the field.
* Focus on process of communicating information from a source (teacher) to a receiver (student).
* Media and devices viewed as components of an instructional design. All components related to specific instructional problems and objectives.
* Fragile connection with this theory and practice began to unwind with impact of behavioral sciences on ET during the 1960s and 1970s.

3. Behavioral Sciences Approach to Educational Technology
* Behavioral science: study of human behavior focused on the fields of psychology, anthropology, and sociology.
* Impact relatively new to ET. Origins can be traced to late 1800s.
* Behavioral sciences as applied to problems of learning and instruction is basis of modern ET concept.
* Includes specialized areas of learning, group processes, language and linguistics, communications, cybernetics, perception, and psychometrics.

3.1. Problems of Integration of behavioral-sciences-based ET
* Prior to 1960's behavioral-sciences-based technology was validated exclusively in experimental classrooms.
* Hilgard (1964) defined an integrative strategy which includes research conducted in a special laboratory classroom, then tryout in a traditional classroom, followed by advocacy and adoption through the creation of textbooks and teacher training.

3.2. Two Theoretical Orientations
* Berelson (1963): for ET to be considered part of the behavioral sciences it must deal with human behavior and it must study its subject matter in a scientific manner.
* This approach has lead to two different instructional approaches in ET: the behaviorist concept and the cognitive concept.

3.3. The Behaviorist Concept of Educational Technology
* John B. Watson and B.F. Skinner argued that science must investigate public, observable events.
* Experimental psychologists focused on observable behavior from 1920s through 1950s.
* In 1950s impact accelerated in field of ET. CAI influenced by this trend.
* Behaviorist concept of ET focuses on the lower cognitive processes with motives being controlled through conditioning.
* Skinner: "Teaching is simply the arrangement of contingencies of reinforcement."

4. The Cognitive Concept of Educational Technology
* Attempts to understand the internal processes of behavior and emphasizes knowing rather than responding.
* Views the learner not as passive but as active, constructive, and playful.
* Learner becomes an active participant in the process of acquiring and using knowledge.
* By the 1980s, the cognitive model began to replace the behaviorist model in ET.
* The organization, processing, and storage of information by the learner constitute vital elements in instructional development.
* Developed the concept of learning strategies: intellectual skills that learners use to control their internal processes of attending, perceiving, encoding and retrieval.
* ET should focus on activating the appropriate learning strategies during the instructional process.

BEHAVIORISM AND EDUCATIONAL TECHNOLOGY: 1950-1980

by, Joan Quinn

Historical overview

Behaviorism can be traced back to ancient Greeks
Basis for American behaviorism came from early 19th century Frenchman Auguste Comte, and Russian physiologists Ivan Schenov (1857-1905), Ivan Pavlov (1849-1936), and Vladimir Bekhterev (1857-1927)
The psychology of behaviorism is attributed to John B. Watson (1878-1958) in his article from Psychological Review entitled “Psychology as the Behaviorist Views It.”
Clark L. Hull (1884-1952) developed a mathematical learning theory based on the idea that learning involves stimulus response conditioning
B.F. Skinner was the leading behaviorist of the 1960s
By the 1970s, behaviorism was on the way out, as cognitive psychology or information-processing psychology became the dominant way of thinking

The 1960s showed a revival of the behavioral objectives movement, with Skinner describing the teacher as one “who arranges the contingencies of reinforcement” and the learner is “conditioned to perform specified, quantifiable, terminal behaviors”.
Franklin Bobbit (1876-1952), proposed that you could determine curriculum by analyzing what people do and then breaking that down into hundreds of specific aims.
W.W. Charter (1875-1956) suggested that the philosopher determine the objectives, and the analyst provide the technique for meeting those objectives.
Ralph Tyler stated educational objectives in behavioral terms, and then designed tests to determine whether these objectives had been met Taxonomic approaches to objectives began in 1948, with the first taxonomy appearing in 1956 (Bloom) after a need was expressed for standardized terminology regarding human behavioral characteristics.
Mastery learning came about in the late 1970’s from the use of instructional objectives as a basis for evaluation.(Bloom)


The Military and Industrial Approach to behavioral objectives
Late 1960s and 1970s, behavioral objectives movement brought on a revival of scientific management to education-the accountability movement

Performance Contracting

Teaching Machines
1960’s Skinner demonstrated a machine to teach spelling and arithmetic.

Programmed Instruction Movement

1962-1963 American schools adopted programmed instruction, which was based on Skinners operative conditioning concepts of stimulus, response, feedback and reinforcement.
Machine-program dichotomy-which was more important?
Decline of programmed instruction by the late 1960’s, but it did make some lasting contributions to educational technology

Individualized approaches to Instruction

F.S. Keller’s personalized system of instruction (PSI) was published in 1968, and did not contain teaching machines or programmed materials. Five features included:
Individually Prescribed Instruction (IPI)
Program for Learning in Accordance with Needs (PLAN)
Individually Guided Instruction (IGE)

Decline of Individualized Instruction

Computer Assisted Instruction (CAI)
First used in education and training in the 1950’s

Conclusion
Skinner behaviorism still impacts educational technology, but cognitive psychology was dominant over behavioral approaches by the late 1970s.

CHAPTER 12

"Development of Instructional Design 1950-1980"

Jeanette Wampach
Leit 642 , Summer 1997

Saettler’s purpose in this chapter is to: (1) provide a brief history of instructional design, (2) survey the development of theories and models of instruction, (3) discuss origins of the systems design approach to instruction, and (4) update the present status of systems design theory.

History of Instructional Design
The author begins by briefly discussing select early educators associated with systematized models, theories, and methods of instruction. These include Elder Sophists, Comenius, Montessori, Thorndike, and Dewey. Their contribution was discussed in depth in earlier chapters.

The turn of the century saw seperation of the academic disciplines of educational technology and psychology. Psychologists retreated into the laboratory and educational technologists turned their focus to hardware and media. World War II seemingly forced these two distinct disciplines to work together to develop effective methods of mass instruction as well as principles and procedures for instructional design. This fertile marriage yielded the rich, initial models of instructional design born in the 1950’s and 1960’s. Skinner’s behavioristic model spawned programmed instruction while Bruner, Ausubel, and others developed models based on cognitive structure. At this time, many saw the need expressed by the Association for Supervision and Curriculum Development "‘...to delineate scientifically based instructional theories from the more intuitively based and somewhat speculative ‘theorizing’ which had been so characteristic of education previously (p.344).’"

The major hallmarks of today’s instructional design process reflect the emphasis on curriculum reform produced in the 1960’s. Notable names which date to this time are: Gagne, Briggs, Glaser, Mager, Carroll, Cronback, and Scriven. Significant components also date to the 1960’s and include programmed instruction, criterion-referenced testing, formative evaluation, developmental testing, Individually Prescribed Instruction, and mastery learning.

Instructional Design Theories
The present major theories of the instructional design field evolved between 1950 and 1980. These are very briefly summarized by the author and include:
1. Bruner’s Toward a Theory of Instruction
2. Gagne’s Hierarchical Task Analysis
3. Gagne-Briggs’s Theory of Instruction
4. Case’s Neo-Piagetian Theory of Instruction
5. Component Display Theory
6. Elaboration Theory of Instruction
7. Structural Learning Theory
8. The Algo-Heuristic Theory of Instruction
9. A Cognitive Theory of Inquiry Teaching

Instructional Systems Design
Instructional systems design grew out of the 1950-60’s as educational technology development paralleled and modeled the systems approach emerging within the military and industrial worlds. The traditional approach to education was viewed as piecemeal, being offered in disconnected fragments. Instructional systems design, where "all components of the instructional process are fitted together into a system" was seen as providing a solution to this problem (p.350). Entire instructional systems were designed using flow charts or lists of steps to be followed. The systems approach provided a ".clear distinction of educational technology in contrast to traditional instruction approaches. Instructional designers utilizing this systems approach included Kemp, Banathy, Corrigan, and Gagne.

While varying in the number of steps or stages, theoretical basis, and degrees of use, systems models share certain characteristics described here by Briggs:
¨ A system is an integrated plan of operation of all sub-systems, designed to solve a problem or meet a need.
¨ Planning requires an analysis and logical ordering of components, with careful coordination of the total effort.
¨ Planning requires an orderly but flexible sequence.
¨ The design procedures are research based as far as is possible.
¨ Design models require empirical testing, actual tryout, and revision.
¨ The final version requires comparison with alternate instruction, or a determination of its value.
Summarized here are the fourteen typical stages and tasks found in most systems design models used for development of an entire curriculum as set forth by Briggs and Wager.

1. Analysis of needs, goals, priorities
2. Analysis of resources and constraints
3. Selection of delivery system
4. Statement of curriculum scope and sequence
5. Design of the organization of courses
6. Design of organization of course units
7. Analysis of objectives
8. Organization of lessons
9. Designing the lessons
10. Assessment of learner performance
11. Development of materials
12. Empirical tryout and revision as needed
13. Summative evaluation of final form
14. Plan teacher preparation and diffusion

Status of Instructional Systems Design Theory
Saettler’s conclusion challenges the prevailing models of instructional systems design which "reflect a linear, ends-means view associated with behavioristic concepts (p.353)" He states that although educational technologists use the concept of a general systems theory to justify their approach to program design, this bears little or no relation to the generally accepted general systems theory as developed by Ludwig von Bertalanffy. Derived from biological systems, this theory focuses on wholeness or the holistic state. It recognizes that a living organism is not a collection of separate elements, but rather is an open system that remains stable in a dynamic equilibrium while the matter and energy that enter it keep changing.

Saettler believes that this description fits the man-made instructional system that must dynamically interact with its environment. This includes the components of "teachers, learners, instructional resources, procedures, administrators, boards, parents, local community, government, and many other agencies (p.354)." The instructional system is composed of many interrelated parts working together to accomplish common goals. The author believes that instructional systems design models have erred by focusing on designing, producing, and validating particular products, courses, or curriculum. Rather it should concentrate on analyzing the classroom environment to gain a clearer understanding of why and how schools function. He sites Bela Banathy’s work as representing this belief, which is at variance with the typical linear instructional designs.

With little progress being made in recent years, Saettler states that the future of instructional design theory is uncertain. "Unfortunately, there is still no sound, comprehensive theory of instruction , and there seems to be a lack of communication between instructional designers and classroom teachers (p.354)." His challenge for instructional designers is to adapt theories into teacher-friendly practical strategies for specific instructional situations. He feels that to be effective, the emphasis must shift towards incorporating practicing teachers in experiments with alternate theories of instruction in actual school settings.

Chapter 14

Educational Technology and the Emergence of the Information Society:
1950-1980
Summary by Loretta Pearson

The Information Revolution which created today's Information Society began in the late 50's with the creation of the first high level programming languages and the appearance of integrated circuits. These events made computer technology, which had been its beginnings in the US at the end of the 19th century, available to a larger segment of society.

Twenty years later telecommunications and computing begin to converge into a single technology. Digitization of mass media is speeded up and the society begins to envision the possibilities for the future. The optimists state the outlook for the future, sometimes with a fervor bordering on the religious. A sampling of their predictions:


Accumulation of wealth and power will depend upon information, knowledge and intelligence. Those who have more information will tend to be materially better off.

Machines will take over the boring jobs freeing people for creative personal and societal endeavors and there will be a global sense of awe and humility for the collective human spirit and its wisdom.

.A set of global ethics will evolve and provide us with the ability to live in symbolic tranquility with our planet.

Of course, these views are not endorsed by everyone with an eye on the future. A sampling of the pessimists:

There is no evidence that our capacity to absorb information has changed, even though there is more information available.

The pace of change is deceptive and there has been no technological speed-up. It took 50 years for television and VCR technology to be endorsed on the large scale. Computer technology is taking even longer to reach the same level of usage.

There is no guarantee that computers and communication will automatically produce a better world and no assurance that the information society will be highly productive, democratic and socially stable. The result could be involuntary idleness.

The impact of information technology on Educational Technology is bleak. In the 50s, the outlook was overwhelmingly optimistic, focusing first on educational uses of television and later on programmed instruction and CAI. However, the inclusion of technology into the educational setting was often a top-down decision motivated by a desire for more efficient management of education rather than more individualized education. The decision makers were often ill-informed about equipment and short-sighted about on-going maintenance/replacement costs, as well as serious training of the faculty who were expected to implement the technology. There was not a firm experimental foundation to steer the development of instructional technology. Significant, also, was the prevailing view that hardware was the key and little or no attention was given to the process of "instruction using technology".

One critic states that schools, in the 90s, are repeating the errors made in the 60s, with educational television. Budgets are being stretched to the limit to purchase hardware and software, leaving little money for maintenance and upgrading of the media. Schools, once again, are not budgeting money for large-scale retraining of teachers. As a result, the technology is not yet living up to expectations.
