Quite a few of the teachers last week also taught Business English. A lot of Genki English style games are actually used by businesses in in-house training ( I learnt a few good ideas on the course I did at Arthur Andersen). At the end of last week’s workshop teachers were saying “Well, yes it does look like only kids could do this. But then again we were all sceptical adults only a couple of hours ago and now look at us!”
From about 13 years old kids go into the funny Harry Potter Effect stage, but the day they turn 20 everybody goes back to being a kid, and basically stays that way till they are 90 or even above. So my tip of the day is to try your favourite Genki stuff in your adult classes, you might just be surprised!
