According to TurnItIn:
Have you seen any of these cited in any of your papers? Sad but true. It is increasingly becoming easier for students to gather what they think is scholarly information on the internet for use in their courses. While students are responsible for what they use and how they use it, what are we doing, as educators, to steer them in the right direction? In education, and especially online education, we can't just assume they know how to find, where to find, how to use scholarly work. We must guide them.
