Why pupils need to keep on reading.

The Guardian reports on a survey which found that teachers are encountering increasing numbers of children with limited vocabularies. There is a fear that this "vocabulary deficiency" will hold students back both educationally and socially. It is claimed that increased incidents of underdeveloped vocabulary are leading to "lower self-esteem, negative behaviour and in some cases greater difficulty in making friends"
