For anyone new to teaching, this book offers a solid grounding in general teaching practise, but generally a little less than one might wish on TEFL. However there are nuggets of useful information, and the book is far more reasonably priced than other guides - as such, it is very good value for money.
I would strongly recommend this for anyone new to teaching, or returning to teaching after a break/moving to teaching adults from teaching children. The book is divided into logical and helpful sections, beginning with generic teaching skills and moving through subject specific areas such as teaching grammar, pronunciation, speaking and listening and writing.
The book is highly prescriptive and makes no apologies for being so,setting useful tasks for trainees that offer a genuine chance to reflect on their own performance. If you are a highly experienced teacher there is a lot here that will remind you of what you know already. Still, it's always useful to be brought back to basics.
