Is repeatedly telling a child to shut up an appropriate way to address chattiness in a class?

I, personally, find shut up bordering on abuse. Especially, in a teaching situation. There are a few other things I would do in that situation that include asking the child to be quiet, making the child sit next to me or asking the child to wait outside the room until they feel they could contain themselves.

In this situation I am talking about a 10 year old child who was in a class with 8 to 13 years olds.

There were other things that went on this class that assured that my kids would no longer be attending.
