Correction: A Positive Approach to Language Mistakes /by Mark Bartram, Richard Walton. Learning a language is a complicated activity. A lot of research has been done in to how to make learning effective but, as yet, it remains surprisingly difficult to say with certainty what methods are truly more effective than others. There is a lot of theory,and even a lot of evidence, but it remains largely inconclusive. CORRECTION is an awareness raising book for every teacher to consider their own attitudes to the hottest issue in the language classroom - mistakes and how teachers should react to them. It is ideal for pre-service teachers' courses.
