Davis (1997), using McDougall & Squires’s Perspective Interactions Paradigm, reflected on professional development for IT in a wide range of contexts. Davis found that there were a further two foci that needed to be added to the list of five: changes in the manager role and evaluation of development and this framework. Davis suggests that the addition of a focus to the framework should be changes in the management of IT in the learning environment. Without the professional development of senior managers, including head teachers, any framework will be unable to hold its structure against stresses imposed by traditional educational organisations. McDougall & Squires’ case study operated within a benevolent ethos and supportive management, but others will need to work towards such an ideal. Davis further points out that an evaluation framework for teacher professional development should itself have an evaluation focus to feed back information into our knowledge of teacher professional development. Davis concludes that the framework may well apply beyond IT to any innovation in education
