This book is one of a set of eight innovative yet practical resource books for teachers, focussing on the classroom and covering vital skills for primary and secondary teachers. The books are strongly influenced by the findings of numerous research projects during which hundreds of teachers were observed at work. The first editions of the series were best sellers, and these revised second editions will be equally welcomed by teachers eager to improve their teaching skills. Ted Wragg and George Brown show what explanation is and what it aims to do. The book explores the various strategies open.
