As, a librarian my tests are not for points while I am teaching but for points students will receive in their research papers for excellent citation and reference pages. So, all of my work is a pre-test. I first pre-test by giving the students an article on a powerpoint slide and ask them how to cite it. This, of course is after I have explained citation and how it works, and why it is so important. Then, I show the correct format, and ask for questions. After a couple of these types of in-text citation tries, I then have students work in groups citing an article from a magazine. This approach reinforces the learning and I of course explain that the library is open for questions, and there is not "stupid question."
