This fascinating account of an unusual research project challenges many assumptions about how young children learn and how best to teach them. In particular it turns upside-down the commonly held belief that professionals know better than parents how to educate and bring up children; and it throws doubt on the theory that working-class children underachieve at school because of a language deficit at home. The second edition of this bestselling text includes a new introduction by Judy Dunn. * Fascinating account of an unusual research project challenges many assumptions about how young children. * Turns upside-down the commonly held belief that professionals know better than parents how to educate and bring up children. * Throws doubt on the theory that working-class children underachieve at school because of a language deficit at home. * The authors' evidence is the children's own conversations which are quoted extensively and are delightful. * The second edition of this bestselling text includes an introduction by Judy Dunn.
