Please offer this only as a PRELIMINARY example of how to format their papers. You don't want to spend any time on this in the first class. Explain that you will go more in depth in the next few classes, but this is how papers should generally "look." Go ahead and ask them to explain the in-text citations to you (there are two). It will help them understand there's a logic to this: it's just author then page number in parentheses at the end of the sentence. But don't get more in-depth than this in class #1.
