The maximisation of teachers’ expertise
Although remarks such as ‘This teacher makes a difference’ and ‘teachers matter’ can be heard quite frequently, not much is heard about how much the teachers really matter with regards to the accomplishments of learners. I will discuss this in my presentation and compare the impact of teachers to other factors. I will then discuss the development of teachers’ expertise throughout the course of their career and how top experts in other domains develop their expertise (deliberate practice). Finally, I will suggest how we can use this way of developing professional expertise for the training and the continuing professional development of teachers; I will also discuss useful and not so useful methods of evaluating the professional effectiveness of teachers from the perspective of professional development.
