plagiarism and students

Caught a student plagiarizing this week. He said he was using his ipod as a dictionary and I guess he thinks I'm stupid. Little did he realize that there is a such thing as www.duplicheck.com. The boy is busted. Will be using this little site more frequently in the future and insisting that my students hand in all work electronically. They must really think I'm stupid if they think I can't figure this stuff out. Just what I wanted. More work...
