'The Secret of Literacy' is an essential book for all teachers and school leaders. It is not just another literacy book. David Didau provides a crystal clear rationale for all teachers taking responsibility for developing literacy in their specialist areas, with lots of very practical ideas, drawing on a range of sources from blogs and the latest literature on the issue. Anyone familiar with David's own superb Learning Spy blog will immediately recognise some of his most powerful ideas and his inimitable style: it is witty and accessible, grounded in the reality of everyday classrooms, but also conveys a sense of urgency. This is a serious business and, as David highlights, too much of what we do in the name of literacy, isn't literacy at all. The book is challenging us to do better and shows us how. 'Making the implicit explicit' captures the key message, but 'The Secret of Literacy' is more than a set of tools; it is a call to arms!
