В блоге Confessions of a Community College Dean преподаватели обсуждают, нужно ли давать студентам extra credit. Коммент:
Extra credit can be used effectively to reward those who go above and beyond the normal course of learning. In a swine production course I took, any student could receive extra credit for volunteering in the meat lab to slaughter and process hogs. Learning how to do this was part of swine production, but could not be fit into the class.
