12 Websites and Resources to Check for and Learn about Plagiarism

My students turn in essays on a regular basis. Sometimes, they are tempted to cut corners or copy and paste information from various web sources, such as Wikipedia. They often turn in essays, which I have to make sure are accurately attributed and not copied from other websites. Often, I find it easier to have my students do their own plagiarism checks before they turn in their essays and I check them. Below are several free websites for students and teachers to do plagiarism checks for free. For more ideas on how to use web tools and apps to enhance student writing skills check out our webinar recordings, Teaching Writing to Digital Learners and Teaching Writing with Digital Tools.
