Now, you, me, concerned teacher and a few others, don't really know our stuff but I don't believe we have to

If you are purely teaching conversational English, such as ordering food or booking hotel rooms, then I agree completely with this. The trouble only comes when naturally curious students ask why something is said the way it is and you cannot give an answer. Or worse you tell them the wrong thing and they apply that to their speech and it can be very hard to undo. I came across that quite often with students in China. I'm also not sure if I'd class purely conversation as teaching, more like a language exchange.

I believe if you are teaching you have a duty to your students, and as a matter of pride for yourself, to do it to the best of your ability. You're not doing bar work, what you do has real impact in the lives of your students and you owe it to them to give them your best.

It makes my blood boil to see attitudes like CT's where he claims he wants to do the minimum possible and skate through to his free time.

As for the Mr Bean lessons, I have a wonderful one centred on Mr Bean Goes Swimming, for use with either 'going to' for prediction, or the 2nd conditional. If you would like it, email me at beth.livermore at yahoo.co.uk and next time I'm in the office I'll be happy to mail it to you (can't do it on my smartphone and no internet in my new apartment yet!)
