10 Percent of Harvard's Popular 'Introduction To Computer Science' Class Accused of Cheating (thecrimson.com)

theodp writes: The Harvard Crimson reports that more than 60 of the 636 students enrolled in last fall's CS50: "Introduction to Computer Science I" course appeared before the College's Honor Council in a wave of academic dishonesty cases that has stretched the Council to its limits over the past few months. Former students and course staff, though, said course policy was unclear about what constituted cheating, creating the potential for unintentional violations. Consistently, one of the most popular courses at Harvard, CS50 is known for an unconventional atmosphere, complete with flashy promotional videos and corporate-sponsored events.

    I don't see how a course that encourages collaboration between peers can then turn them in for cheating when they come up with the same answer. You can't collaborate without often coming to the same result using the same methods.

    While coding, in its purest form, is a creative act the same is not so of most 'coding 101' problems. They are often rote mechanical pieces, intended to highlight a particular software concept, with little room for creativity (especially if, like any sane student, you're trying for the simplest and shortest solution).

    Unless they are monitoring the entire typing history for students, and they only brought students up on charges where their submission was created with a single keystroke (Ctrl+V), I don't see how this is a fair system.

      There is a definite conflict between what the course encouraged and what the Harvard academic policy discourages when it comes to collaborative classwork. I ran into it headfirst at the last time a Harvard cheating scandal happened - and I was in THAT class, so had firsthand knowledge. I know people in CS50, so have some real knowledge here too - it will be interesting how/if it is resolved. The panel that does the academic honesty reviews is not something you want to face - it has some real bite, and students do get expelled.

      FWIW I tend to name my counters i, j, k. After that I start to get creative. I trace that naming pattern back to Fortran IV, where that was the recommended pattern, and names could only be six letters long, but it's become a tradition in multiple languages since then. I could find examples in C and Java texts.

      The thing is, for a short piece of code a long name is a waste of time. If something's less than around 20 lines long, a fancy name is a waste unless it's doing something external to those 20 lines. (Yay! Block Structures!).

      It is simply not true that an English adverb must indicate the manner in which the actor performs the action.

      Adverbs come in two kinds: "verb phrase" adverbs such as "carefully," which do refer to the actor, and "sentence" adverbs such as "frankly," which indicate the attitude of the speaker toward the content of the sentence.

      Other examples of sentence adverbs are "accordingly," "basically," "confidentially," "happily," "mercifully," "roughly," "supposedly" and "understandably." Many (such as "happily") come from verb phrase adverbs, and they are virtually never ambiguous in context.

      The use of "hopefully" as a sentence adverb, which has been around for at least sixty years, is a perfectly sensible example.

      Came here to say that too. I often collaborated on the work. We sort of naturally split off into groups of 3 or 4. Sometimes spend hours with heated arguments back and forth. Then of course on those problems (i.e. the difficult ones) we'd turn up to the tutorials with identical working. Those questions would then usually get the majority of the attention, because what's the point in going over the ones everyone found easy?

      The sessions made absolutely zero contribution to your final mark. About the only reason for cheating is if one had a bit of a, ahem, "busy" week and wanted to save face. Having been on the other side of the table, it's usually easy to spot, especially as students with hangovers always have a certain look. If it started to happen often it would be cause for concern, but it never did for me.

    I've heard that argument before. The student caught copying someone else's work first denies, then pleads, then goes into "lawyer" mode, trying to argue that what he or she did wasn't really cheating because the syllabus was either badly worded, or didn't specifically say not to do it.

    I recently had a situation where a student taking a lab course did not attend several labs, and then tried to turn in lab reports and have the TA grade them. This student was shocked ... shocked ... when told that this was academic misconduct. After all, the syllabus said that data could be shared between lab partners, and the person he got the data from was his partner from one of the few labs he did attend. Furthermore, he argued that the syllabus did not specifically say that lab reports would not be accepted for labs that the student did not attend. I kid you not.

    Anyone smart enough to get into Harvard knows exactly when the line between collaboration and plagiarism is being crossed. Unfortunately, some of them also have learned that denial, pleading, "lawyering", and then threats of legal action by their parents are quite often sufficient to avoid the consequences of their actions.

      Computer programming is a little different....

      CS50 has always been fast and loose. I can remember showing weaker students my code and letting them copy a few lines or the answers to early problems. And vice versa. Many times TAs were in the labs shoulder to shoulder with us helping us with problem sets. Collaboration was always encouraged as long as you came up with some original ideas for harder problems and you weren't blatantly ripping off other people. Intro to CS is designed to get to pretty challenging material quick. You can't get to the fun stuff if everyone has to solve every easy and medium problem from scratch. Back in the dot-com days, passing CS50/51 with a good grade was sufficient to get a professional programming job, regardless of major. Those who didn't go to Harvard may not realize that getting easy problems 100% right is not culturally respected in the sciences there -- most exams are solely problems that range from hard to extremely hard and a 50 or 60 is an A-.

      Plagiarism is a tough standard to apply to computer science at the intro level, similar to plagiarism in algebra. I completely understand and respect the Be Reasonable concept -- that's how we rolled (I took CS50 at roughly the same time as the current professor). I saw stuff that went over the line as well (printouts fished out of bins or stolen from printers, cut and paste specials) I like the Be Reasonable concept, but it has clearly reached its limit if this many students are getting dragged into investigations.
