How to be a successful English teacher at junior high school

Hello!
I took a Mr.Maruhashi's class in last week. He said that teacher's job is changing students. That means, in 50 minutes class, Teacher should teach something for students. So, if a student feel being bored, the class will be to useless one.

To be a successful English teacher at junior high school, the most important thing I think is to be kind and friendly for everyone. In a school, one of the important thing is COMMUNICATION.

Last year, I did teaching training in a junior high school.
First, I can't talk with students friendly. I didn't understand why. But, one day, I noticed it.
When I talk with some boys in the class after school, we laughed again and again.
Then, they began to speak to me. Next week, I could speak most of the students of the class.
I did just laugh with some students, but it was very important thing for me.

So, to be a successful English teacher at junior high school , communication is very importabt thing.
