I have a group of 60+ year old women at intermediate level.
They are all retired teachers.
This is their third course with me.

They aren't particularly fluent, certainly not as they should be.
The problem I have with the group is that between themselves they are ultra-competitive and are all too ready to jump in and correct the others when they make a mistake . Apart from being infuriating on my part, it's completely killing off the speaking activities - most of them are afraid to open their mouths!

I've asked them not to do it, I've told them not to do it, I've begged them not to do it. They still do it. I can't really blow my top at them (delicate sensibilities and all that) so WHAT CAN I DO TO STOP THEM?
