Tennis: serve 8

How do I coach 14 girls, all of varying levels from beginner to advanced on just two courts?

Psychology in tennis HELP!!! I have a daughter who is an excellent player who only started playing tennis seriously last yr at the age of 13. She is a much better player than all the people she has completed against in matches but always loses due to over hitting and getting upset if the wrong call is made (which happens frequently due to how fast she hits and serves) do we need some sort of psychological help for this. what is the best way to get this... books, councilling ??? any help would be most appreciated thanks

Helo, my name is Fernando, I am a Spanish tennis teacher who started teaching six months ago. I am working in a public sportcenter and I am having some problems with adults. When I started I realiced that the students were used to playing tennis without any control. Young students told me that the other teacher only used to leave them play - he rarely explained them how to hit the ball. Consequently the do enjoy my clases and they are learning a lot and impoving their level of tennis. So far so good, but the problem is that with the adults I have the impression that they don´t like my clases. In fact some of them left the group at the begining. I try to mix different kinds of drills during the class and I usually finish it with a game like for example 21, winner........ But it seems that they don´t enjoy it. During the exercises most of them don´t try to do what I tell them. As a result, they don´t have a good level of tennis. But as far as I know, the other teacher was a tennis player who uses to play against them during the clases. As this is my first time teaching tennis, I don´t fell confidence and that is the reason whay I do´t like to play against them. Appart from that I think that this is not my role as a teacher. So I would like you to tell me how to deal with that situation. I don´t care if they leave me because this is not going to affect my job, but i wouldn´t like them to leave just because I like tennis and I like teaching tennis. Thank you very much for your help. I am sorry for my English. Best wishes!!!!
