What is instructional technology? Whenever I introduced myself as an instructional systems major to someone I just met, they always asked me what this major was about. If I used the term "instructional technology" to explain what the instructional systems is, they seemed to come to an understanding of what I study for my major. They immediately related the instructional technology to the web-based instruction, educational CD-ROMs, and computers. We need to understand that the use of the machine is only one aspect of the technology. Solomon (2000) pointed out that "alternative perspectives in our field assume a broader interpretation of technology as the systematic application of all sources of organized knowledge." Based on this viewpoint, technology consists the products, the artifacts such as machines and tools, as well as the processes, the ways of doing things such as strategies and techniques.
It is from this view of a broader interpretation that Seels and Richey (1994) defined the field of instructional technology, i.e. "the theory and practice of design, development, utilization, management and evaluation of processes and resources for learning." Their definition reflects the evolution of instructional technology from a movement to a field and a profession and the contributions this field has made to theory and practice.
Different terms have been used to represent the field. Schrock (1995) used the term instructional development as a broader context for her description of the history of the field; Reiser (2001) used the term instructional design and technology to define the field. To Shrock (1995), instructional development is "a self-correcting, systems approach that seeks to apply scientifically derived principles to the planning, design, creation, implementation, and evaluation of effective and efficient instruction"; To Reiser (2001), "the field of instructional design and technology encompasses the analysis of learning and performance problems, and the design, development, implementation, evaluation and management of instructional and non-instructional processes and resources intended to improve learning and performance in a variety of settings, particularly educational institutions and the workplace." Both terms encompass the same broader scope of the field as the term instructional technology.
The following descriptions of the historical development of the field of instructional
technology incorporated Reiser's and Shrock's thoughts.
Instruction was interpreted in the metaphor of exercise, in which the mind was thought to consist of faculties in need of exercise
The advent of scientific investigation into human and animal learning
Edward Thorndike's influence of laws of learning, his advocacy of social engineering, his advocacy of educational measurements. It led to establish education as a science
Bobbitt: the goals for schooling could be derived from an objective analysis of those skills necessary for successful living·
The design of instruction was the connection between the desirable outcomes and the planning of the instructional experience that could facilitate their acquisition.
The emergence of the concepts of objectives, individualized instruction and mastery learning
Tyler's Eight Year Study: refining the procedures for writing instructional objectives; recognizing the cyclical nature of evaluation within the process of creating instruction designed to produced specific outcomes, i.e. the recognition of the formative evaluation process
World War II: the creation and distribution of the mediated learning materials
A large number of psychologists and educators were called on to conduct research and develop training materials for the military services. Development of training materials were based on their work on instructional principles derived from research and theory on instruction, learning and human behavior.
Psychologists used their knowledge of evaluation and testing to help assess the skills of trainees and select the individuals who were most likely to benefit from particular training programs à examining general intellectual, psychomotor and perceptual skills
Research and development effort directed toward education.
Emergence of the role of the instructional technologist; formation of the basic instructional development team: designer, SME and producer calling for professional development of a new field
Skinner's research into operant conditioning
Skinner's programmed instruction: behavioral objectives, small frames of instruction, self-pacing, active learner response to inserted question, immediate feedback.
Shifting education's focus to the outcome behavior of the learner instead of the process of the behavior of the teacher.
Reaffirming the feasibility of a self-pacing and mastery learning· Task analysis was first used by Air Force personnel in the early 1950s.
Bloom's Taxonomy of Educational Objectives (1956)
Articulation of the components of instructional systems and the recognition of their systems properties
Robert Gagné's The conditions of Learning (1965): a milestone that elaborated the analysis of learning objectives and the relationship between different classes of learning objectives and appropriate instructional designs
The essential features of systems, i.e. evaluation and feedback resulted in the refinement of evaluation procedures, developing criterion-referenced measures
Federal support of the instructional development: in 1957, after the launching of Sptunik by the Soviet Union, the USA government poured millions of dollars into improving math and science education. The instructional materials developed with these funds were usually written by the subject matter experts and produced without tryouts with learners.
In the mid-1960, Michael Scriven (1967) pointed to the need to try out drafts of instructional materials with learners prior to the time and the materials were in their final form. Scriven indicated that this process would enable educators to evaluate the effectiveness of materials while they were still in their formative stages and, if necessary, revise them before they were produced in their final form. Scriven named 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.
The broadening of the field of audiovisual instruction to embrace the larger concept of instructional development and technology.
A decade of consolidation: Proliferation of ID models
Addition of needs assessment to the collection of steps that defined the ID process
The field reached out to the literature of consulting and change agents for information to assist with its growing complexity· Graduate education programs focusing on instructional systems design grew
Existing associations of professionals were redefined: DAVI became AECT; publication of Journal of instructional development
The instructional application s of microcomputers have come to dominate
Performance technology movement, with its emphasis on front-end analysis, on-the-job performance, business results, and non-instructional solutions to performance problems, was beginning to have an effect on instructional design practice (Rosenberg, 1988, 1990; Rossett, 1990)
The growth in the utilization of instructional development by business and other non-school agencies
Merrill, Li and Jones (1990) discussed the need to develop new models of instructional design to accommodate the interactive capabilities of this technology à computers began to be used as tools to automate dome instructional design tasks
The influence of the performance technology movement: broadening the scope of the instructional design field to include analysis of the causes of performance problems and non-instructional solution
Growing interest in constructivism. The instructional principles includes:
Use and development of electronic performance support systems (computer-based systems designed to provide workers with the help they need to perform certain job tasks, at the time they need that help, and in a form that will be most helpful)
Rapid prototyping: this design technique has been advocated as a means of producing quality instructional materials in less time than is required when more conventional instructional design techniques are employed
Use of the Internet for distance learning
Knowledge Management§ Rossett (1999): knowledge management involves identifying, documenting, and disseminating explicit and tactic knowledge within an organization in order to improve the performance of that organization.
