Reasons For Plagiarism

Sometimes students plagiarize not to cheat but because of other causes. Some examples:

The entire concept of plagiarism just doesn't make sense so they don't document sources. If you are unclear on it talk to your teacher or a librarian so you avoid trouble.

Students use an idea from a source but change the wording. Documentation is still needed.

Sometimes students feel like they have to document everything in their paper and it will look dumb, like they didn't have anything of their own to say. This is a tough one, but when in doubt include documentation. Also, talk to your teacher or a librarian.
