Nathan Grimm just shared this great list of resources on how to handle plagiarism in the classroom including sample policies, a list of online tutorials to help students understand what plagiarism is, and tips for discouraging plagiarism. As he notes:
Plagiarism is one of academia's most common problems and a constant concern for teachers. While the Web may have made plagiarism as easy as a few simple clicks, it's also made detecting plagiarism just as easy. If a student can find the essay in seconds, so can you—if you know where to look.
