As Computer Coding Classes Swell, So Does Cheating (nytimes.com)
An anonymous reader shares a report: College students have flooded into computer science courses across the country, recognizing them as an entree to coveted jobs at companies like Facebook and Google, not to mention the big prize: a start-up worth millions. The exploding interest in these courses, though, has coincided with an undesirable side effect: a spate of high-tech collegiate plagiarism. Students have been caught borrowing computer code from their friends or cribbing it from the internet. "There's a lot of discussion about it, both inside a department as well as across the field," said Randy H. Katz, a professor in the electrical engineering and computer science department at the University of California, Berkeley, who discovered in one year that about 100 of his roughly 700 students in one class had violated the course policy on collaborating or copying code. Computer science professors are now delivering stern warnings at the start of each course, and, like colleagues in other subjects, deploy software to flag plagiarism. They have unearthed numerous examples of suspected cheating.
if something like that happens, you just pull both students in independently and ask them to explain how the code works and ask a few pointed questions. In general the students who copy do it because they don't understand the problem or how to solve it, some won't even understand the language they are supposed to be working on.
Funny story in college I had an instructor end class early because he was so enraged by a cheating student. I think it was the complete lack of effort that did it, the student turned in the 1st assignment from last year for this years first assignment, despite the fact that the problem had changed.
Heh, I'd have been the dick who wrote an automated obfuscator. Flip the indentation from spaces to tabs ( or tabs to spaces ), randomly change ctime/mtime ( within acceptable range ), camelcase to underscore ( or reverse ), use a dictionary to change variables to their synonyms, add generic comments ( ala "palm reading" ), randomly placed returns ( where language appropriate ).
Figure that wouldn't take more than an afternoon to code up.
Could get even crazier by adding the ability to swap out loops ( foreach to while/for ), but those can impact overall grade and is language specific so it'd have to wait for v2.
Mod me down with all of your hatred and your journey towards the dark side will be complete!
an unlimited number of variable names
What? There are only 26 letters. a = b; b = c; and now I've already used up 3 variable names.
