I agree, a combo of both is best. Maybe I've been a bit over-enthused/over-emphasetory when it comes to discussion based classes at my University, because there usually is some lecture. The professor still gives the students information, shares their points of view, etc. That's just not all the class is. Of course a professor needs to impart their knowledge on whatever the subject is.
I have had awesome professors when it comes to lecturing. One in particular lectures more than others, and he's awesome. He'll still get the class involved from time to time, though.
35 students in a class isn't my way. That's way too many people to have an effective discussion--too many students will get overlooked, won't speak up, will be able to "hide" from the conversation, etc. I'm betting you never got into any real discussions--where you actually debate and exchange ideas with the professor and other classmates. In my English class, I have 22 students, and that's still a few too many, in my opinion.*shrug* That's the education I prefer, which is obviously why I buy it. If I wanted all small-class "active learning" courses, I'd go to a small college, I did for a few months. Thirty-five people per class, lots of discussion, they hold your hand the whole way and focus on instruction a lot more, but the instructors and the equipment and facilities aren't as impressive by half. The cost of a university vs. community college is comparable here, so you really do have a choice at least up until the end of your second year, in most cases. After second year you usually have no choice but to to transfer to a big university if you want a bachelor's. Anywho, what I'm saying is, given a choice and having experienced both, I found the teaching method which employs lecture much more enriching than your way.
This is a risk, no doubt (the whole no risk, no reward thing, no?). I've had one in every class. Have one now. The teacher has to be savvy enough to pick something out of their tangents that can move the discussion forward. Sometimes (usually) I can, sometime's I can't. If I can't, I'll just fall back on "What do you guys think of what so-and-so said?" And then the conversation moves on. As for them talking so much, I just tell them, "Okay, so-and-so, I see some other people who want to talk, let's see what they have to say" (they never seem to get offended). Sometimes the class will just fall back on this person and let them do all the work, in which case I address the whole class, "Come on, guys, you can't let so-and-so do all the work."Come on, no one else here hates classroom discussion? It's the most embarrassing thing in the world when someone is too stupid to know they're stupid and seeks attention in front of strangers. The instructor stumbles around trying to find some way to escape the situation, but sometimes the student won't shut up and keeps going and going. Sometimes they do it in every class for the entire semester, and when they raise their hand your brain just shuts off and you recede into yourself until it's over.
