One of the models of blended learning is a rotation model. Best used in an elementary classroom, the rotation model has students moving to an online environment for 10-25 percent of their day.

Rotation: In this model, students move on a fixed schedule between online learning (which is most often self-paced) and traditional teacher instruction in a classroom.
I think it would be interesting to take a different piece of Blended Learning and try with different subject matters in a pilot - to really get a feel for which ones work better in different situations.
