With secure subject knowledge and understanding, trainees develop confidence and authority and are better equipped to become effective and creative teachers. This coursebook has been written specifically to help trainee primary teachers develop their science subject knowledge. This new, third edition has been completely revised and updated to match the new QTS Standards, and reflects latest thinking from the Primary National Strategy and other recent initiatives. Material has been reorganised where appropriate and research summaries brought completely up-to-date. All the popular, existing features are joined by new tasks to help trainees develop the key skill of reflection.
