Scrolling vs Print Type Interfaces

To Scroll or Not to scroll:
According to a recent paper many students retain more if the material is presented in print-like format, on separate pages.

Students were presented with material that they had to scroll to read or as material in separate pages, navigating by the next-back functions of the browser. The students who used the material in separate pages did better in reading comprehension.
I wonder what this implies for sites like Blackboard, where you can break content into Folders or arrange in a Learning Unit. It probably says that having all content in one Item is not a good way to arrange information. However, I find that students who print out all material prefer that form of presentation.
