The trick here is to turn this question on its head. Make sure you tell the interviewers about your positive behaviour management strategies you use and then you can go onto behaviour issues after, but leaving the emphasis on how you do promote good behaviour in the class.

A model answer could be something like:

"First and foremost I plan my lessons to be interactive and fun. With students engaged in their learning then it is less likely any behaviour issues would arise in the first place. This is backed up with positive reinforcement of what I expect from the children in terms of behaviour and the effort they are putting into their work."

"The next action I put into place is myself and how I act as a model to the children. I will always act like how I want the children to act. Being a positive male rolemodel is so important, especially where some of these children don't have one at home."

"Allowing children to feel good about what they have done is a great way to make sure they make the right decisions in terms of behaviour. So a well done in front of the class, or stop the class for them to show off their work and get applauded at the end or a massive praise from the teacher always puts a smile on their face. This is the attention children want. They want to feel good about themselves."
