ABSTRACT
This chapter describes the evolution of educational technology in its various guises will be considered from the psychologist's point of view, but first it is necessary to introduce the three major psychological theorists whose early work profoundly affected the development of educational technology throughout most of this century. Educational technology is composed of at least two overlapping subsets: technology in education and technology of education. Educational technology can be seen as an umbrella term for the application of scientific knowledge in the field of education. Psychology is particularly well-represented, including cognitive psychology in addition to those aspects traditionally associated with educational technology. Psychology as the behaviourist views it is a purely objective experimental branch of natural science. The new brand of psychology was also to provide an answer to the question 'What is the bearing of animal work upon human psychology?' which, Watson admitted, had caused him some embarrassment.
