I started to teach just now and I could perceive how students help us to learn more and better. Teachers commited with theirs students study a lot to be a good teacher for them. I've learned many things about English as a language and about teachers. Every day I learn something very nice to improve my career and my knowledge.

As teachers we need to keep an open mind. The English Language is an ocean by itself and the best we can do as teachers is to become better with each passing day. Since our delivery is focussed on the students it is imperative to keep ourselves updated on all apects of the Englih Language. The young generation of today has got easy access to any kind of information they want. Moreover, they are not the type who will keep quiet and relate with whatever inputs you share with tem. They will have lot of questions and queries for which you need to be prepared. If you are not able to answer their questions, it will seriously affect your reputation.

However if the question is not valid or related or if you feel there is a deviation from the topic under discussion you should cut them off then and there and not encourage any further communication.

The bottomline line is to be on your toes. 

I think a teacher improve for to be  a teacher because she study for the students understand her or him. When a teacher don´t know a topic she/he teach bad. therefore he need to learn the topic and teach the student good
