On the other side of plagiarism

Or "confessions of a term paper ghost-writer". Interesting in its own right as a sub-cultural phenomenon, but with a sound point at the end;

I don't have the academic credentials of composition experts, but I doubt many experts spent most of a decade writing between one and five term papers a day on virtually every subject. I know something they don't know; I know why students don't understand thesis statements, argumentative writing, or proper citations.

It's because students have never read term papers.

It's an exercise re-discovered time and again, like the wheel; get students to mark/grade and comment on specimen papers written for your module, so they know what they are supposed to look like.
