A glance at the history books or the pages of a Dickens novel reminds us how far education has come since the days when pupils sat silently in rows memorising knowledge imparted by the teacher. Learning was passive, and only gender and social class affected provision. In today’s schools learning is at the centre of what we do and differentiation – the process of modifying a lesson or part of a lesson for one or some of the learners – is a fundamental part of teaching. Turning theory into practice and including 20 key types of differentiation, this Pocketbook is about planning and teaching creative, student-focused lessons where every learner is appropriately challenged and where engaged, stimulated and motivated students work in a state of ‘flow’. In this kind of environment true differentiation serves not to label but to enable.
