It is all about how you communicate with your students. If you could not achieve this goal, you will not be able to teach.
In order to do so you have to put in mind several points. First, THE BODY LANGUAGE, students can take more information in when you interact with them using your body & they have the ability to understand. After that, you should pay attention to your pitch. You should make sure that your voice is not low neither high, put in mind that you will need to change the pitch sometimes to restrain order or to make a point.
When communicating with students you have to know how to treat them according to their age and cultural background.
Before the interview remember that you will be teaching not for the money only but for educating a whole generation, which will build the county in the future.
