Is one of the subjects in an interview in the Education Guardian with Jude Carroll, of Oxford Brookes University. Academics' teaching styles may inadvertently encourage students to cheat (setting the same assignments every year, for example), as may assuming students know what counts as plagiarism when they don't. There are some responses to the article in this week's Education Guardian (3rd May) - scroll down to see them.
The Library, incidentally, can help teach referencing, and also the use of Endnote, a reference management software package supported on CFS machines. I am offering some training and have posted about them separately.
