Good teachers use good techniques and routines, but techniques and routines alone do not produce good teaching. This text suggests that the real art of teaching lies in the way that teachers exercise their professional judgement in circumstances where there is no "right answer". This combination of flexibility, informed guesswork and constant self-monitoring is not easy to acquire, but David Tripp aims to show how teachers can draw on their own experience to develop it. Although the book raises important theoretical and methodological issues about teaching and research, it is primarily intended as a practical guide, illustrated with classroom examples and extensively tested with teachers.
