How to punish your student?

If my student's keep making the same mistakes over and over again, some form of punishment would be warranted.

My question is, what type of punishment is the best?

Tell them they're wrong and be snarky.  "That move is logical isn't it?  Well you're wrong."

  "You call that a tactic?"

  "The goal of chess is to make the other guy lose!  How do you expect me to lose when I'm simply a piece up?" 

"Wow and here I thought I'd be putting in lots of work to win unanimous control over that square and you handed it to me for free!" 

"Thanks for saving me the trouble of forcing new weaknesses in your camp (usually during strategic endgames.) people typically have to work to provoke that sort of move!"

Well what is the mistake?

If your talking about a mistake as like a wrong move on a board game than their shouldn't be a punishment.

How can you punish someone for making a wrong move? When even Grand Masters make wrong move's?

EDIT: I added more

If your opponent got caught cheating or something than a punishment may be warranted but in a chess game it really sounds ridiculous to give a punishment. 

I also believe a chess punishment will act as counter productive. They might begin to hate chess or the punishment might take effect and they might stop making such move's but than later on in their chess career they might arise in a position when they must play such a move and they will be psychologically scarred from the punishments and probably will dismiss the move.

Get a hold of a Cocker Spaniel, tie the suspect down on a chair with a potty on his head, then pop his todger between two floury baps, and shout "Dinnertime, Fido!"

What about spanking? Is it feasible?

I love this one. Have seen it in a Prague museum of torture machines. :)

Don't give him lessons anymore.

Haha its more like: Potty = a bowl that is used before someone becomes "toilet trained", todger = his 'family jewels', and bap = a type of bread/bun. 

It was actually a quote from Blackadder IV, where General Melchett is advising Blackadder of a way to interrogate a suspected spy ;)

Always blaming the in experince Student huh?

The staff on another thread said you are a cheater.

So perhaps you should stop crying to us and learn to play chess without cheating.

My karate teacher always told us that that are no bad bad students, just bad teachers.  Try something different to get through to them.

have you tried tying their hands together and attach them to the fender at the back of your car ?

If you believe punishment is the way to correct a students mistakes, then perhaps teaching is not the best thing for you to be doing.

I've been teaching for more than 10 years and I've never had to use punishment to correct a students mistakes.

Also, keep in mind; Do you never make the same mistakes over and over in your chess play? Of course you do. Otherwise you would be the world chess champion.

So just stick to reminding them of their mistakes, why they are mistakes and what can be done instead. I think you will find,in the long run, this is  the most effective approach.
