There is no set process or method with reference to disciplining of students. Using stick or shouting at the students shows that you are not capable of controlling the class and you will lose the respect of the students.

I always maintain that the first day for a teacher at any institution is the most critical factor. The impression that you create on the first day, stays with them throughout and more importantly, gets passed to subsequent batches. If you try to win the students over to your side by trying to be their favourite, it becomes very difficult for you later on, to change your methodology. You will see lot of resistance from the students and shouting at them will only further damage your credibility.

If you sense that the class is going out of control, maintaining continuous eye contact without speaking will have a powerful effect. You could also pick up students who act smart or play pranks, by asking them to come out and do an embarrassing activity. You could also have the batch system where students are graded on two parameters, as in knowledge and discipline. The green batch should be worn by students who are involved and disciplined. The red badge is for the other crowd and it is titled pigs. Ensure that they wear this batch throughout the day.  

Oh, what a pity.  I read an excellent article on this not long ago, on onestopenglish.com.  Unfortunately it seems to have been moved to their locked articles (you can read it only if you subscribe) - it wasn't before.  If I remember correctly it was by Adrian Tennant, but I could be wrong.

Four things I remember from it, that I think are particularly useful and relevant are:

• Some of the main reasons children misbehave/disrupt the class are: a lack of motivation; the task is too difficult; the S finished the task before the other Ss and has nothing to do.
• It's useful to talk to the student about the behaviour.  Ask the S why he/she is doing it.  Explain to the S why it's a problem.  Children are capable of acting like adults and thinking maturely in these kinds of situations, and often recognise that their behaviour wasn't appropriate and can then monitor themselves more carefully for a while.
• Punishment often leads to Ss misbehaving more, not less.
• Punishment should only be used as a last resort.

That gave me a few ideas.

• Make the class engaging and the activities relevant to the Ss.
• Make the tasks achievable.
• Have back-up tasks for quick finishers.
  
  
• If a S does cause problems, talk to him/her as an adult first.  He/she will probably discipline his/herself.
• Try to avoid punishing Ss or you'll end up with them acting worse.
  
  
• In the end, though, there might be times (the last resort) where you do need to punish them.

Not sure if 'the stick' counts though.  That's a bit rough.
