Teacher development has existed for a long time and in history there are excellent examples of teachers who have continuously sought deeper knowledge and wider perspectives through their own study and participation in a community of colleagues.

One can say that TD in this respect is both a result of IT and a pre-requisite for a quality in the use of IT in education.
