Yes, absolutely.
We're looking at some very new learning tools or technologies where students are paying out of pocket; they're nominal prices like, say, $20 per half credit, for example. One example that comes to mind is Learning Catalytics. It's similar to Cengage learning where the faculty member has access to the entire repertoire in the catalogue and students are paying $20 compared to a $200 textbook. I think this is where we are beginning to see the shifts in the way in which consumers or students value course material, and also, understanding that it is for a single half-credit course. Typically speaking, unless they are professionals, they tend not to hold on to them.
