Why Computer Science Students Cheat

alphadogg writes "Enrollment in undergraduate computer science courses is at an all-time high at colleges nationwide. But this trend that's been hailed by the US tech industry has a dark side: a disproportionate number of students taking these courses are caught cheating. More students are caught cheating in introductory computer science courses than in any other course on campus, thanks to automated tools that professors use to detect unauthorized code reuse, excessive collaboration, and other forbidden ways of completing homework assignments. Computer science professors say their students are not more dishonest than students in other fields; they're just more likely to get caught because software is available to check for plagiarism. 'The truth is that on every campus, a large proportion of the reported cases of academic dishonesty come from introductory computer science courses, and the reason is totally obvious: we use automated tools to detect plagiarism,' explains Professor Ed Lazowska, chair of computer science and engineering at the University of Washington. 'We compare against other student submissions, and we compare against previous student submissions and against code that may be on the Web. These tools flag suspicious cases, which are then manually examined.'"

Re:How many ways are there to do simple things?

This would be flagged but wouldn't pass the manual review. As a former Graduate Teaching Assistant, cheaters are easy to spot because they are LAZY! They turn in the exact same files (same comments with same misspellings) with maybe a different name at the top. The only good way to cheat is to make sure every things is perfectly correct and has no identifying characteristics.

It's neither new nor subtle; it's why expertsexchange now hyphenates their URL: experts-exchange.com.

Methinks many are missing the point

The many examples here of array declarations or variable initializations are not sufficient to get you pegged as a cheater. But when you get multi-line programs of dozens of lines that are precisely the same, even including comments, THAT will ring alarm bells. I don't think anyone writing a simple 'Hello, world' program that is exactly like mine will get called out. If you turn in a hundred line program full of regression equations to plot the Fry Readability Index in a matrix graph that is precisely like mine? Busted!
