Placing a child in seclusion is degrading and this form of punishment is not allowed by European laws and it shouldn't be allowed here.  Embarrassing a child does not encourage a positive change. By treating the child differently, you are telling them they are different. And worst, you are effectively telling all of the other children in that class to do also treat that child differently. Children follow the example of their teacher. If a teacher can segregate the child and embarrasses them, then they will do the same. The child will start be believing they are naughty, and guess what? It is now part of their identity.  It is a self fulfilling prophecy. 

We should be doing 'time ins' not 'time outs'!
