Great example of an open group desk arrangement. Student desks are in groups, but all face the smart/white/chalk board. This arrangement facilities a great environment for establishing good student-student relationships.
I really like this class arrangement! It is also the most space efficient one. When we first introduced notebook classes it seemed to be the easiest solution to simply keep the layout and adjust the power supply to the existing situation.
Desk set-up: none of the desks are side by side, allowing each student have their own personal space but still work collaboratively when appropriate. When desks are side by side, or students share table space, it is much easier for issues to arise.
