BSP Trees

Hi all!
We just covered BSP Trees in my OpenGL class. My professor is not a very good communicator when it comes to these things. Can anyone tell me in layman’s terms, or reccomend a good tutorial website for this topic. My whole class is utterly confused as to what they are used for, or how they are formed. Any help would be much appreciated.
