My question is how rectangular....a little bit might be ok....but not too much....hmmm In really large group (what I would call 220)...the best I have seen....is the low angle....curved near square (slightly rectangular) theaters with lots of room to move behind rows...usually 2 row each low angle teir Really pay attention to the quality of the room acoustics.....if I can see you and hear you....it will be OK There are some specific facilitation techniques in large groups to encourage interconnectedness I have one of my faculty that is really talneted at this.....If you want I could try to gt you connected with him Jim Sibley Sorry for brief message -sent from my iPad On 2012-05-21, at 7:03 AM, "Clements-Jewery, Hugh" <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hi All, We are in the process of designing a large facility for TBL. The facility would encompass the entire class (approx 220 students). Thus far the architects have come up with a room of rectangular proportions. We are worried about the possible lack of ‘inter-connectedness’ (for want of a better phrase) of the teams in a rectangular room – can teams at one end (or one corner) of the room have difficulty feeling and being a part of the inter-team discussion? Is there any hard evidence that a room with a square design would help with ‘inter-connectedness’ (we’ll need to back up requests to the architects!)? I understand that many of us make TBL work in facilities that are non-ideal, but theoretically what room proportions would you have if money, practicalities etc were not issues?
