A great way to give the children awareness of their discussions is to film them. It can be very enlightening to review a discussion by watching it back. I did this with a class to demonstrate to them that when they all talk at once nothing is achieved. They were quite taken aback at how this looked and how ineffective this was. From watching this film we were able to discuss what we should be doing and put things in place to learn from this and move forward. We used tokens for the children who dominated the talk and when we filmed the children a second time the discussion flowed much better enabling more children to have a turn talking.
