Hello Georgianne
I had 240 geography students in a lecture theatre that held 245 this last semester. It is difficult but I assigned each group a designated seating area with three in front and three behind - the ones in front could then turn around and sit on the desks when required.  I did have to change some of the group sizes to accommodate shorter or longer rows. Unfortunately we also had class in two different rooms so it took a bit of planning. It was not ideal but we managed :)
Good luck
Joe :)

Hello,
Last year was my first  time applying TBL. It was very successful but I have run into a big roadblock for this fall. I'll have 192 intro to biology students and a lecture hall with 192 desks - no central hallway - just a block of 192 fixed desks.
Has anyone found a creative way to adapt this pedagogy when in-class groupings aren't possible?

Thanks!
