Do colleges/university have school bells?

Question

I've noticed recently that most colleges on television or in movies have bells signaling the end of class. I have attended two universities myself and visited three more for guest lectures and never have I heard a bell ring. Is this just something for dramatic effect - or just to let audiences know that the fictional class is over, or are there some schools have these bells?

Answer 1

No, I don't think any colleges have bells since there are classes going on at all different times.  

Answer 2

It is just for effect in the movies. Because you notice that classroom scenes are always at the very end of a class. It is a plot device that allows the writer to terminate that scene and move the plot onto the next scene.

Answer 3

There aren't even clocks in the classrooms at my school. I'm effed if I forget my cellphone.  

Answer 4

Each school has its own system. Private and public schools may or may not have a bell.  

Answer 5

At the university that I attend, less than half of my classes have a clock on the wall. And there are no bells, but there is a large clock tower that rings. I can't here the tower ring when I'm in a building. I have not even seen a clock in the student union building.

Answer 6

they do have belltowers...just like prisons
