the systematic use of knowledge for intelligent human action
"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."
Heinich, et al. defined instructional technology "as the application of our scientific knowledge about human learning to the practical tasks of teaching and learning."
1. Physical Science or Media Approach to Educational Technology
2. Audiovisual Communications: A Synthesis of Communications and Systems Concepts
3. Behavioral Sciences Approach to Educational Technology
This approach has lead to two different instructional approaches in ET: the behaviorist concept and the cognitive concept.
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.
* The organization, processing, and storage of information by the learner constitute vital elements in instructional development.
* ET should focus on activating the appropriate learning strategies during the instructional process.
