ABSTRACT
In education the larger number of models and strategies are based upon the transfer from theory to practice. The actual process of change is viewed as an orderly and logical sequence which begins with the identification of a particular problem or the conception of a specific idea, proceeds through the development of possible solutions and prototypes, and ends with the diffusion of the product to a selected target group. Here the major emphasis is upon the planning of change on a large scale, for which specialised institutions, such as laboratories, experimental units and research agencies, are required for scientific research, development and rigorous testing and evaluation. For the distribution and installation of the innovation in a target system mechanisms must also be included. The prototypes of this model will be found in industry, defence and agriculture.
