Well all my uni courses seem to be broken into the following
Lectures= You sit in a lecture hall and a professor explains the section of the course you are learning that week, its similar to a lesson at school except you dont do any work whatsoever its just a lecture, sometimes there are demonstrations though which jazz things up.
Tutorial: Most subject have tutorials, once you have had your lecture on a particular subject, you usually have a tutorial sometime in the following week, for most tutorials you walk in, they hand you a sheet of practice questions and you and your buddies in the tutorial work through em. Most of the people who take tutorials are in 3rd or 4th year so they are really friendly and you can talk to them about stuff.
Lab: The lectures introduce you to the theory, and the tutes make sure you are capable of doing the thing on paper, but labs are usually where you actually apply your knowledge. Im doing engineering so i have plenty of labs, i think some subjects dont have them though. I.E in physics labs we do experiments, in elec labs we build circuits.
Seminar: I only have seminars for computers, its a little bit like a cross between a lecture and a tutorial, you learn a little but you also do some work. Probably more similar to traditional school learning, but you know with the respect that comes with being at uni.
Anyway, i find having a clear division between learning theory, applying theory and doing it in practice is really helpful.
