You can watch this tutorial, which covers plagiarism basics and some finer points as well, and then take the quiz as a guest. If you decide to register your class, students can take the quiz and send the results to you.
The most substantial overview of plagiarism avoidance techniques that we have on the WVU campus was put together by members of the Pyschology faculty several years ago. Its multiple modules with quiz functions are embedded in the Faculty Toolkit for Information Literacy which is located in the Learning Academy portion of eCampus. Select the Getting Started tab in this LibGuide, open the toolkit link, and use your Master ID to get in. Check it out too as you are reviewing all of the resources we offer to help students avoid academic dishonesty.
Plagiarism and How to Avoid it is a PowerPoint lecture and discussion used in WVU Libraries ULIB 101 courses and is usually augmented with an in-course exercise. The exercise sheet is available here.
