Book excerpt: Metacognition is one of the most highly effective but under-used teaching strategies in all of education. Over-complicated by some, over-simplified by others and misunderstood by many, this area of theory and practice is in need of a fresh look. The Metacognition Handbook provides a clear, practical guide for teachers and school leaders to embed metacognition into classroom practice and school culture to enhance student outcomes. Looking at classroom pedagogy, teacher CPD, transition, and more, The Metacognition Handbook argues a case for evidence informed application of simple but effective ways to boost student independence, self-regulation, self-efficacy and motivation.
