ABSTRACT
There is, then, inevitably a time lag between the concept of any particular change or innovation and its adoption. So that, in order to reduce the time lag, it is necessary first to isolate the many factors which operate when any given innovation is introduced into the education or school system. Clearly our understanding of the process, models of change and of the strategies which eventually will emerge, all depend upon the interactions of factors which are:
inherent in the innovation itself;
situational or connected with the school system and its personnel; and
environmental.
