Rogers E Miller (1971)
'An idea, practice or object perceived as
new by the relevant unit of adoption, whether it is an individual or an
organization'
APEID (1977)
'An effort to introduce a practice in order
to bring about a social change. The practice need not be totally new: its
efficeincy and potentiality in a new context are the main criteria used in
labelling is as innovation. The emphaisi is on change in terms providing a
strategy to deal with specific local or national problem'
Vanterpool (1990) - the characteristics of
an innovation that predict a high probability of success are implicit in the
following questions:
1.
Relative advantage (compare
with what exists)
¨
Will it be more effective in
improving learning?
¨
Will it be conserve resources
more effeciently?
¨
Will it have a position impact
on the total programme?
2.
Compatibility (consistent with
values, xperiences, needs)
¨
Will it fit well with other
aspects of the programme?
¨
Will it be accepted?
3.
Testability (can be tried on an
experimental basis)
¨
Has it been tested in schools
like ours?
¨
Can it be pilot-tested?
¨
Can we use selected parts?
4.
Observability (can be seen in
action)
¨
Can we see a live demonstration
with children?
¨
Can we see a videotaped
demonstration?
¨
Can we see variations in its
application?
5.
Complexity (ease of use)
¨
Will teachers need special
training?
¨
Will it add to teachers'
paperwork?
