Following definitions by Havelock and Huberman (1978) and Nicholls (1983), innovation can be defined as a deliberate effort, perceived as new and intended to bring about improvement. As such, innovation is distinguished from change which is any difference that occurs between Time one and Time two. What is crucial in innovation is that it is change involving human intervention.
Since human agency is involved, innovation can be viewed from many angles: individual, social, organizational, political, technological, and historical. Not surprisingly, much attention has been given to the technological aspects of innovation, among which can be included language pedagogy.
