TO every experienced teacher , help!
I have a serious problems controling my class at the beginning before I start the lesson. As soon as they get into the classroom , they start talking and it becomes really hard to attract their attention . Another thing is that when I set them on task , very few students concentrate and the rest of the class gets noisy . What do you advise me to do? PLEASE HELP!
