Ok I can't describe this move very well... This guy is a teacher at a high school and then begins to start teaching martial arts to a kids and then others began to get into it also. I remember that they al lgo on this trip and take the bus while they are learning more about martial arts and respect etc... the end of the movie is a fightseen between a teach and ibelieve another martial arts teacher.. I remember they sang this song that went.. "bah nah nah waaaaay bah nah nah way nanana " If anyone knows the name of this it would be greatly appreciated

Oh also it's a martial arts movie , American and modern times I believe

Sounds like Only the Strong (1993) (http://www.imdb.com/title/tt0107750/)

And I think I just found the teacher who did it I believe his name is mark dacascos

YEs that's it... THANK YOU

You're welcome.
