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.
