I have been a teacher on a High School in the USA for some time. (Now not anymore)
The thing I noticed what that schools only got bigger and bigger and bigger. So, I hope that this will change in the future. Why, simple, because you see first of all that crime is getting a real problem. But you also see that kids can not concentrate in a class, simple because it is to crowded !
What do you thing need to be changed in school ?
