Have you read Dr. Harry Wong's book "The First Days of School"? If not, put your coffee down and run to the library, bookshop or both.
What was never going to work?
I've just read J. Harmer's "How to teach English" where he has a fairly long section explaining his "E.S.A." procedure, and the individual engage, study and activate stages.
Ugh, teaching grammar again next week and I'm not sure where to start.
Why does it take so long to plan one single lesson?
