Success at school and beyond depends to a large extent on being able to make yourself understood. This book looks at the way adolescents express themselves and concentrates on the discrepancies in language use between academically successful and unsuccessful pupils in an educational setting. The authors analyse situations where transfer of information is the prime consideration and suggest ways in which the teacher can step in with practical help. The book explains in non-technical language and with humour the most important findings of a three-year research project into adolescent language. It uses many examples of transcibed speech to demonstrate how communication sometimes breaks down, disabling a pupil's performance and suggests how that performance can be improved.
