Use of the native language in class

Please insist that your students speak English in class, even to each other. Unfortunately, this is the only English practice some students get, so we should ensure they have as much exposure to the language as possible. If someone is truly stuck, the native language may be used – briefly! – to get past that point and then move on in English.

If you feel it is necessary to separate students who insist on chatting in the native language during class in order to help them and the other students learn, then you should do so.
