Techniques and Technology: Affecting Variables That Make a Difference

Educational technology involves the application of psychology and equipment to the solution of educational problems. Teaching is facilitated when the interrelationships of variables such as time allowed for learning perseverence, quality of instructional materials, affective behavior and goals, and aptitude are considered. In order for educational technology to have a maximum impact, attention should be directed to the manipulation of as many of these variables as possible. The educational technologist should seek to uncover new functional relationships that will lead to advances in understanding the instructional process. (CH)
