I think the main issue for me is the time it takes to deal with problems and the interruptions, sometimes it’s really hard when you’ve got children chipping in all the time, and I guess that’s the hardest thing when you are trying to teach something, in the instruction group you might be, and that child is constantly na, na, na don’t want to do that, na, na,na and you’re getting this constantly, and you can see the frustration on the other children’s faces.
