You can see my before and after of my seating arrangement in the videos below.
I created the document seen here to give my students choice (see #1--that was meant for the Smartboard group I recreated with my desks).
When my students were given time to work, no one needed help at the Smartboard. They headed straight for the hallway to do their challenge or right to a lab station! My desk arrangement was almost not needed for this activity how I hoped it would be used!

I still think the purpose of this challenge was met--it was not the physical space that enhanced the learning environment, but rather the fact that I was given voice and choice--so that I could give my students the same voice and choice I have experienced. Most days students are up and at stations doing lab and activities. The benefit now is that they can easily talk to their groups during our current PBL and I have heard great conversations as they have worked together!
