The takeaway of applying aikido-like redirection techniques (don't try to fight cheating head-on, but instead change the problems so cheating is meaningless) is a generally applicable life lesson.
>I was also lectured by some senior professors that "I should change my assignments from year to year". (Thanks for the suggestion, buddy, this is exactly how I detected the cheaters.)

what? how can there be cheaters to detect if the assignment is completely different?

My guess is that the OP was a bit imprecise, and that he kept some assignments the same as previous years. If 3 assignments are same-same-different, and a student gets grades A-A-F, that could be what they call a 'tell' :)
On second reading, the OP was being sarcastic, and derisively noting that if he changed his assignments, he never would have caught the cheaters in the first place. So he rejects one form of making cheating useless (making traditional assignments, but changing them up each year) and embraces another (choosing different types of assignments that are structurally not cheatable).
I believe the intended reading is that he does "change" them, by adjusting the font, etc, as mentioned just earlier. His colleague was suggesting that he write entirely new assignments each year.

The author misunderstood what his colleague meant (Or at least, only does a half-measure), which is why he says that "He is" changing them.

(I am the blog post author).

No the suggestion was not to create entirely new assignments every year. This is problematic, not because it takes time, but because is it hard to "debug" the assignment, and make it to be not too hard, not too easy, and not ambiguous. You cannot know this before actually giving the assignment out to students.

The senior professor was just suggesting to change the numbers, or small elements of the assignment. A thing that I was doing already.

It explains in the article that he changed certain elements of the assignment so that it was obvious when someone turned in the old version.
While I sympathize with the instructor and think he should be incentivized to fight cheating, I'm not pleased with the use of services like TurnItIn. Basically, the student gives someone some faceless company a license to whatever they create for perpetuity. Are these companies ever compelled to delete material on request? And who could audit that?
I completely agree with this sentiment. It is difficult for me to express how extremely inappropriate I think it is for a school to transfer ownership of a student's assignment to a third party who uses it strictly for profit. It would already be iffy if turnitin was a nonprofit, but they aren't.

Papers that students legitimately write and no third party ever gains access to, are still inflating their essay counts and therefore making some guy rich.

The courts upheld that it isn't a copyright violation since they decided it was fair use, but I have to say even if it is legal it is morally abhorrent for schools to go along with it. Plagiarism is unavoidable from individuals that are trying to scam their way through school, and something that needs to be combated, but universities are supposed to be bastions of enlightenment not cronies for privately held corporations.

To be clear, I don't see any problem with automatic plagiarism detection. I do see a problem with very significant profits being made due to usage of students work that they cannot possibly opt out of (especially high school students who don't even have the option of transferring schools if they don't want their work being used that way)

So would writing "Copyright (C) 2011 J. Random Student, all rights reserved" on ever essay you hand in make any difference?
You already have a copyright just by writing it. Courts have ruled this is fair use, which means the courts feel this use of content is more valuable to society than writers keeping their rights.

I wonder if laws would change if we were talking about combatting plagiarism in film schools by keeping a database of all films to match against.

If it's fair use, the student keeps copyright, they just can't go after Turnitin etc. for copyright infringement. Lack of infringement != losing copyright. If the professor were to, say, publish an anthology of student papers, this would not be fair use and he'd have to either get permission or risk being sued by the students.

There're various other cases of fair use that make this fairly obvious, eg. when you DVR a TV show, that's fair use, but it doesn't mean that the MPAA has lost copyright over that show and can no longer go after people who share it on Bittorrent.

Yeah, my comment was unclear. I didn't mean to imply the students lost their rights, just that the courts have decided this particular use supersedes their rights under the fair use doctrine.
A fellow grad student got blackballed and ultimately kicked out of the program for bringing this up to the chair of the department.
I am the professor who wrote the blog post.

What you mention was a very big problem for the adoption of services like Turnitin. In fact, when there is a match, there is no way of seeing the "source" of the homework, unless you get a permission from the "owner" of the homework.

Also, students when they submit the assignment to Turnitin, they assign a license to index the content for plagiarism detection purposes, and for nothing else.

And students have the right to remove their assignments from the index, if I understand the language of the agreement correctly.

students when they submit the assignment to Turnitin, they assign a license to index the content for plagiarism detection purposes, and for nothing else.

I thought you said it was integrated into Blackboard, thus not requiring students to directly submit their assignments to Turnitin?

There are many ways for which most of the same benefit can be gotten, such as having the software be paid for by each school, which would host it itself and maintain its own database. Crawling from the web would still be feasible (just with a lot of duplication of effort between universities), and you would still be able to catch students at the same school who copy from each other---and most of the students who copy from others are going to copy from students who attend the same institution.
Great tale, and I like the approaches he suggest at the end that make cheating impractical. Hopefully, as a tenured professor, he can serve the likely storm of pressure he will get from his university for publishing this.
Jeez, is it so hard to do your own damn homework? Maybe the prof should just let things get messy until it becomes more work to cheat than to just do it legit and maybe actually get some value out of school.

But I guess school is now just a status thing that you do to satisfy other people instead of yourself (or so everyone says), so why should anyone care about doing it honestly?

"Cheating" is a meaningless concept once you reach college in my opinion. Either students are learning or they're not. They're (usually) paying money to be there and the only applicable metric is if the skills they acquire while chasing down the degree are worth the money they or their parents spend. To that end, I was impressed with the OP's thoughts on deterring this sort of behavior in the future. Because really, the only person suffering from this behavior is the student. By altering the coursework to make the motives for copying virtually meaningless the professor's goal is accomplished with a minimum amount of effort.
> "... the only person suffering from this behavior is the student."

Actually, everyone suffers. Fellow students suffer, as some are compelled to cheat to compete because their peers do. Alumni suffer as students grades lose their value and the university is seen as less rigorous. Similarly for academia as a whole. Finally, society has to deal with whole cohorts that have been formally rewarded for making poor ethical choices.

the only person suffering from this behavior is the student

You really think so?

The more diplomas you give to students who learned nothing, the more the rest of the world will pick up on it and refuse to hire anyone from your University.

Also, the more unqualified people get through college, the less a college diploma means. I wouldn't say that cheating is the only reason for the problems with the college diploma in the U.S., but it's a substantial contributor. The 20% cheating rate observed by this professor is fairly normal across the entire country and a lot of unqualified students get through by cheating.
Also, the more unqualified people get through college, the less jobs there are for non-degree holders. Why would you hire a school leaver, when there's plenty of degree holders lining up for the job?

So the diploma is worth more, for the students who just scrape by. Unless diplomas start to lose all credibility.

I couldn't agree more. There are a few schools ("good" ones!) that we get a fair number of applicants from where I've learned to just ignore applicants' GPAs when evaluating them, because they're inflated to the point of being useless. The candidates might still get an interview, but it's now hinging entirely on the quality of their cover letter and whatever extracurricular things they've posted to GitHub/Google Code/Kiln/whatever. In other words, their godawful expensive Ivy League education is now literally worth less, to me, than some of the much smaller, cheaper tech colleges whose GPAs I've found are actually at least vaguely reflective of the students' abilities.

People such as your parent post make my life easier, I guess: when in doubt, I can get lazy and throw the résumé in the trash. Otherwise, I think that it's way past time for universities to start caring about grade inflation, whether it comes from widespread cheating or from lazy professors.

Full disclosure: I am a college dropout - so take this with a grain of salt.

At the very least, it matters, if only a little, to the reputation of the institution. If they start turning out plagiarizing idiots, eventually they become unable to charge as much for that education.

Others will suffer if the students continue the practice in their later accounting, legal testimony, health and safety practices, and business partnerships.

Do you think after succeeding with cheating through college, they can turn it off like a switch when the stakes are higher?

Yes, the student is the only one suffering. Going to school and not learning anything is pointless and the diploma by itself is worthless in the long run.

Unless it turns into a complete party place, the university will do just fine and employers don't really care what your grades are and how you got them.

... until they get a job writing for an online info-database, and their idea of creating new content consists of copying wholesale competitor's pages.

I wish this was true, but it actually also hurts all the students who aren't cheating in the course since their classmates are receiving better marks than them while spending less time. Which tragically creates a strong incentive for other students to join in. In some courses this can be an epidemic and you have a significant fraction of the students cheating and getting better marks than the students who are actually learning.

When curves come in to play it means the honest students are getting lower scores than the dishonest ones even though they are learning more. This can suck in a lot of fields where grades matter.

The refrain that it only hurts the cheater needs to stop being something people say when this topic comes up. It is a serious problem that is undermining learning in our classrooms and it needs to be addressed, it is not a victimless act. It certainly does hurt the cheater, but it doesn't only hurt the cheater.

Don't fix it for the sake of the dishonest students, fix it for the sake of the honest ones.

There is no evidence that cheating hurts the cheater. Sure, they will learn less. But if they get higher grades from cheating than from trying to learn and not scoring as highly, then this will get them a higher wage in many professions.
Anecdotally (hmm, I'm good with the non-data today), there is a very strong correlation among my friends between not cheating and professional success. The ones who engaged with the material and really tried to learn it are doing very well for themselves, even if they flunked a few courses as a result. It's probably stronger than the GPA-to-success correlation - I know several summa-cum-laude graduates who've since flitted between low-level jobs and continuing education.

Makes sense, really - I've found that your actual skills are the primary limiting factor on your salary, and credentials just make it easier to get the jobs you're already qualified for. While some folks try to game the credentials, the rest of us are working on skills so we can hit the ground running, and actual, tangible accomplishments speak much more loudly than degrees.

That's not necessarily true. Lot's of people can "talk the talk" with a highly embellished resume and land a job.

As a result of the cheating, grade inflation becomes worse and a possibly highly able candidate with a 3.4 GPA may completely miss the "GPA filter" on a resume sorting algorithm for a cheater with a 3.6.

Thats why sorting and filtering by GPA is something I never believed in and hope other people stop doing as well. A good GPA is an indication of a capable candidate but the opposite may not be true.
This is totally and utterly untrue. The only person who gets hurt by cheating are the students who don't cheat. The professor doesn't have to teach and the school graduates that many more 'grade A' students.

And, this is the fundamental problem: the schools really aren't in the teaching game. They are in the successful enrollment game.

That would be nice, wouldn't it? Unfortunately it's quite easy to find people who barely finished schools but could talk well and landed a job... and then they must really mess up to be fired - they can usually survive doing the absolute minimum.

As long as you work for someone who doesn't actually know what you're doing, it's not that hard to hide the fact you don't know either ;)

It seems like the professor tried to personally deal the problem on a case-by-case basis; this will always end up being more work for him in the long run. What he should have done is just immediately hand the case off to the proper authorities and let them decide the case. However, I'm assuming from the post that the council at this particular college is considered to be a last resort option; other colleges have committees that are dedicated to dealing with cheating and it's standard procedure amongst faculty to forward all cases to them immediately.
I don't know what it is with you US Americans and "cheating"... but it seems to be a very touchy subject in your culture, almost like violating someone's honors. I never understood that.
When you cheat you violate an agreement everyone has made either explicitly or implicitly. When you violate an code of behaviour to your benefit, others may suffer. It shouldn't be very difficult to understand that causing someone else to suffer for your own gain is "touchy" at best.
Just out of curiosity, where are you from and how is cheating regarded there?
I am Austrian and studied in Austria. Cheating is not really considered special or extra-ordinary in any way here.

Pupils in school would try it, also students later on might try to... generally it is the duty of the teacher or professor to keep students from cheating here and 95% of the time they are very successful at it. The remaining 5% are considered fair game by the students.

Most tests (as in over 90%) do not allow you to use books or any other material; sometimes students would try to hide notes or get an answer from a fellow student but ultimately with the teacher watching and the situation in the class room being really quiet, in most cases there is hardly anything you can really do or find out anyway but maybe you can get one or two hints tops.

Also, most exams (at least where I studied) did not have multiple choice tests instead you would have to write a proper answer and apply knowledge. So at best someone could whisper a clue or hint you in the right direction

In case you got caught talking/cheating you might get one or two warnings and then your test is taken away from you and maybe also from the person you were talking to, depending on course and professor.

The difference for me is: amongst students, it is not a "crime" here.. you are trying to help your fellow colleagues mostly "against" the teacher and while still covering your own ass. It would be considered rather offending NOT to help on purpose when you have the chance to.

Another difference might be: I did not have to pay upwards of 100k to get a decent education. So maybe studying is more a "commodity" here in Euroland.

The American perspective tends to be that you are the system (decentralism), not that it is you versus the system (authoritarianism).

Unfortunately America has also become infested by the idea that punishment creates virtuous people, especially among those with an authoritarian bent. Attempts to outlaw decentralism fail, so they pack all the authoritarianism into those cases where centralized intervention is needed. Hence the rise of zero-tolerance policies for everything. That's how we reach the point where a university opens up a can of ass-whip for a essay that forgot a pair of quotation marks (you can't swing a dead cat in the English department without hitting a sanctimonious liberal).

As a student I pay thousands of dollars to earn a degree from a respectable institution. When students cheat and get away with it like in the OP's article, it dilutes the value of my degree.
Not only that, it can also wreck the classes. If the response to rampant cheating is "oh, the course was too hard", then the standards to which students are held will fall.
Because the cheater gets out the other end of the degree course with a degree they didn't earn. And then they start competing for the same jobs as me.
Its funny how almost all of this hard work put into cheating, copying, changing, editing etc. leads to one line on your resume, the GPA. A good GPA gets your resume short-listed at the very least but someone who never earned the GPA is extremely easy to catch in an interview, especially for CS majors. A little digging into that project you got an 'A' for and it all comes tumbling down like a house of cards. All it achieves in the end, is a waste of the interviewer or recruiter's time.
It is totally a question of honor. It is utterly dishonorable to cheat, and egregiously so at the levels described in the aforementioned blog.

The goal of the scholastic experience is so that you, the student, learns something.

If the school turns out people who didn't learn, they are producing worthlessness.

It is a lie to say that you have a degree, when you really have a collection of credits that you cheated through. The degree is worthless and should be sent back.

You are exaggerating by 200% and leading it ad absurdum.

"Cheating" for me means getting one or two hints at an exam and with the exam situation being what it is, those hints typically only really help to jog your memory if you did study. It does not mean downright plagiarizing your thesis and 90% of your studies.

But US Americans seem to be offended even at the idea of getting or sharing a single hint during an exam. Here in Europe you could easily loose "street cred" and be forever labeled as the worst kind of "nerd" if you did NOT at least try to help a fellow student on purpose. Again, I am not talking about writing 100% of homework for you but sharing a hint or a small piece of help during an exam.

Funnily, we had a few very, very high profile cases of plagiarized doctorates amongst politicians here in Germany. Their degree was taken away from them of course.

"Cheating" may mean that for you, but it's not what it means for most people, and certainly not for "Americans" in general. Panos is pretty clear in his post about what was going on. This wasn't "hints" or anything close.

20-95% of the content in some of these papers was being copied straight off the web without even a citation. It's plagiarism, just like the high-profile cases you recently had. How is that not cheating?

No.

I assure you, what you describe is considered cheating, but the cheating that usually takes place is far more comprehensive.

It is violating honor, the honor of the institution and everyone who is sacrificing their time and treasure to advance your education.

The rules governing cheating are even sometimes called "Honor Codes".

Finally, from a Christian perspective, putting your name on work you did not complete is a form of lying and is immoral.

I really hope that the downvotes aren't from people who dislike this poster's Christian perspective.

I suspect that the HN majority is atheist, but it's still no excuse.

Disregarding any particular poster's religious affiliations, understanding "Christian" values can shed a great deal of light on the foundations of American culture. I think it's an excellent point at any rate.
I suspect that the HN majority is atheist

Really? I get a sense that there's some outspoken atheists here, but I don't see it as a majority.

I guess that would make an interesting poll.

Why is this and my replies (with detailed descriptions) being downvoted? It was an honest question about cultural differences.
Fascinating read... sort of rings bells in my head along the lines of DRM/piracy cold war.

Reading the article and see the greater and greater extents the students were going through to cheat and the arms-race occurring between the teacher and the students, he leads you to his ultimate conclusion: the game has to change.

You can see the writing on the wall as you read through. Written "brain dump" style assignments, unless changed every year, aren't going to yield great results. Interactive, group-driven projects, competitions and discussions are all things that are much harder to plagiarize, are more fun and will (hopefully) teach the students more.

Not to mention more fun to teach.

I have a lot of teachers in my family (midwest) and none of them glow when they talk about teaching... they describe it like a war of attrition between the teachers, the students and the administration... like there is some clock ticking away slowly in the background and everyone is going through the motions just trying to outlast everyone else. I am talking about 2 separate generations here, like 40 years apart saying the same thing.

I can't imagine a shittier experience.

On the other hand, I am friends with a few (younger) teachers out here in the west that are rabid about how exciting their class is and how much fun they have.

The common denominator here is that the ones having a blast frequently do highly engaging and custom events in the classroom like re-enacting scenes from a play in drama on-the-fly or the poly-sci teacher segregated his class for a week while teaching about separate-but-equal.

Those are micro-examples, but what I'm getting at is that the teachers that recognize that the game has changed are still having a great time teaching.

Just like /cgi-bin shopping carts and "DO NOT HIT 'Purchase' TWICE!" buttons are dead on the web, so is the schooling experience of yester-year. If school wants to stay relevant, it has to compete with the allure of these extremely fast lives we live now. People cashing in $100,000,000 companies at 22 makes it tough to argue why your kid should stay in school until he's 73 so he can make $80k as an architect.

I wouldn't want to go to school now, a lot of things seem in flux. Notice how popular the "Why go to college?!" conversation is now adays?

I think in 10-15 years it will be much different/more effective with a different outlook though; that'll be a more engaging and compelling experience I hope.

Notice how popular the "Why go to college?!" conversation is now adays?

'people' cashing in 100M companies is as common a career path as "NFL Athlete". It works for a very few, special people, but not the broader population.

Notice how popular the "Why go to college?!" conversation is now adays?

I can assure you that conversation (in the context you mean) is not happening all over, but rather limited to a small subset of Internet echo chambers.

My kids still get the same rhetoric from all directions. Unfortunately, that rhetoric doesn't include a cost/value justification. Education is an investment and a means to an end, but most people don't see it that way.

I have had many courses in which the answers to the homework are given prior to the homework assignment. The assignment is large enough that copying the answers would take about an hour. Most students feel that if they are going to spend that much time faking it, they might as well do the assignment. Furthermore, biweekly quizzes clearly highlight a lack of understanding. Not doing the homework (or just copying the answers) is a rough road to go down, when averages midterm scores are in the low 60s (and yet some kids ace the midterm). Those who copy the homework do badly in the course. It's just that simple.
As a student, I have no complaints about weekly quizzes. I attend university because it gives a structured environment to learn new material and quizzes help keep me focused on what I know and what I only think I know. But extending the time it takes to finish graded homework assignments? It's a waste of my time. I'd rather relax, work at a part-time job, learn a new programming language, or work on some project. Busywork is not why I decided to go to university; the internet provides a free avenue to learn everything I would in university (undergraduate). I pay for the classes, the structure.

(Clarifications. To stay enrolled, I have to maintain high grades, which means homework is an obligation. And yes, I have other motives for attending uni beyond someone telling me what I should learn next. There's the value of a degree outshining being self-taught and how close to 99% of students from my highschool take higher education. University is part of the culture here.)

These are weekly homework assignments. 5 hours on average. It's not too bad.
While there's much to be said in favor of more creative assignments that aren't minor variants of last year's assignments, the author has drawn the wrong conclusion from what happened.

22 cheats out of 108 is big - and the real proportion may have been even higher, given that it seemed like he caught only either blatant cheats or conscience-stricken/less brazen cheats (the latter category from when he acted people to own up). And it's a lot of work, and I've been around this process at a couple different institutions and seen how tough it is to see it through to an appropriate conclusion.

However, all this wasted time, and all this aggravation, wouldn't be necessary if all the other professors were doing it too. The only reason they're at 28/108 or higher is that people have obviously been getting away with almost anything.

The author has buckled (understandably) as being the only hard-ass in a environment where everyone else is getting away with it isn't feasible. From his perspective, I can see why he didn't fight this, but if he'd stuck it out for another year or two - and showed the next round of incoming classes just how ugly it will get - he'd have gone back to 'normal' cheating rates rather than 28/108.

The idea that you can always produce assignments that are 'unique flowers' that can't ever be duplicated year by year by cheating students has its own pitfalls. One problem is exactly that these assignments _are_ unique flowers, and might turn out to be systematically too hard or too easy or too vague. An advantage of the rather mechanical, "near-clone of last-years stuff" approach is that you can learn from last year's assignments and tune them onto the target. Faculty shouldn't be dumping the same material without fixes every year, but in many fields it's insane to expect that they have to prepare all new assessment material every year. They just don't get paid enough or get enough time for that.

but if he'd stuck it out for another year or two - and showed the next round of incoming classes just how ugly it will get - he'd have gone back to 'normal' cheating rates rather than 28/108.

I don't think this is necessarily true. I can construct arguments either way, but they depend on big ifs. I think it's unreasonable to ask someone to go through a professional grinder for two years because things might get better.

Your claim that the author has drawn the wrong conclusion relies on a major assertion for which you have failed to provide support. Specifically: why do you think a 22/108 cheating rate is non-standard for a large US research university's business school? Are there institutions that check such things in any sort of systematic fashion (e.g., TurnItIn run on a substantial portion of the classwork)?

It seems to me that the incentives that Panos describes, such as poor evaluations, funding/salary, disinterested administrators, and awkward one-on-one confrontations are common to many top institutions.

(comment deleted)
Ah, the starchy HN argument style, lacking only a demand that I provide citations. Unfortunately, you're deploying your pomposity in the service of refuting something I didn't actually write.

I didn't say that 22/108 was "non-standard for a large US research university's business school". I said it was "big". It is big. This doesn't change if the norm at every other business school is 32/108. The OP also thought it was big and was unhappily surprised by it.

pbh brings up solid points. Stating that something is big will always lead to the question "relative to what?"

Your post indicates that you think 28/108 is big relative to what a normal cheating rate would be (as can be seen by your statement "he'd have gone back to 'normal' cheating rates"). How can you establish whether or not something is big relative to a norm when you haven't even established what the norm is?

From the rest of his comment, it seemed reasonable to assume he meant "big" relative to most people's sense of fair play.

I'm having trouble picturing an argument for how a 25% cheating rate would be "small".

Anecdotally, 25% cheating rate seems really low compared to what I observed at my top liberal-arts college. I would've guessed a cheating rate of about 60-70% to be "small", and 90% to be large. On my floor of incoming freshmen, I'd say those of us who had never cheated were in the minority, and in fact many of my floormates expressed incredulity that there were people who could've gotten to college without cheating once.
I made a different conclusion. There are several problems, but the biggest is his approach.

Now, I'm not a teacher, and all those caveats. But in my imagination, my approach would be much less time-consuming. I cribbed this from my high school physics teacher. It involves little detective work and no long drawn out confessions.

When cheating is detected, simply send a note to the student with the following: "I'm aware that you cheated on this assignment. You have received a failing grade on it. The next instance of cheating will be referred to the honor board and you will fail the class." Any student who wished to contest the charge would be referred to the honor board immediately. Contest it with people whose job it is to handle this sort of thing. The policy on cheating would be posted at the beginning of class and strictly enforced.

The reason why this is so much more efficient is because the net time spent compared to a non-cheating assignment is probably negative. This is simply because you no longer have to read or grade the papers that are found to be copied. Since there is no conversation to be had with the student, there's also no extra time spent there. The only marginal cost is if a student wishes to appeal your verdict, but I doubt there will be much of that happening since the consequences would almost certainly be more severe.

This also solves the problem of bad ratings. There's no need to play the hard-ass in this situation, which is probably where the rating trouble comes from. Since the interaction is terse and factual, the students won't have much face-time in which to build resentment. You could even put something like, "I know you can complete this class successfully, which is why I'm not referring you to the honor board on the first offense. Please come to the TA's office hours if you're having trouble on your papers in the future. I look forward to working with you and helping you achieve your goals in this class" at the end of the email to put a positive spin on it. (Although the idea of having ratings come from people with whom the professor is in a somewhat adversarial relationship seems like one that could be improved.)

Anyway, I see where this guy is coming from but I'm not sure his is the right decision. Maybe I'm wrong though because as they say I have not walked a mile in his shoes.

James, I did exactly what you suggested. Every single student came to protest. I believed that things would play out exactly as you are thinking. Unfortunately, they turned out very differently.
Is it a departmental problem?

I understand that people will cheat and that as technology changes the game it's potentially harder to catch them and that's ultimately not your job. Does the school use character as one of the attributes when selecting students? Should they maybe be more selective? It just seems like a staggering number of cheats.

You ever collect any statistics on it? Are there certain trends?

How about taking a harder line then? Make your warning at the start of the semester, and to everybody: any reasonable suspicion of cheating results in an immediate referral to the honor board, no protesting or second chances. The first assignment rolls around, a few people are caught cheating, and you spend X hours submitting their cases to the honor board. Let the honor board handle the adjucation of the matter, which is where it belongs, and wastes less of your time. It also lets the department know that they have a problem, since some of them are probably involved with the honor board.

Students hear that peers are getting sent straight to the honor board, and they fall in line. The next assignment that rolls around, almost surely less students will attempt to cheat. If you have to spend Y hours sending more students to the honor board, hopefully Y is less than X. But it sends a loud-and-clear, unmistakable message to the students that cheating is unacceptable. With any luck the students that actually take the class seriously will appreciate your candor on the matter.

I agree that allowing students to actually come in and argue their case to you is a waste of your time. You're right, that's not your job. Send it to the honor board and waste the time of the deans and the department heads, since that's their job. If you let students waste your time by giving them an extra strike before they're out, you can't be surprised when they try to take advantage of it. One strike and you're out tells students that it doesn't matter if ex post facto you think your best friend's grandma's death drove you to do it: cheating is never acceptable.

Huh, interesting. But I got the impression from your article that you typically had a discussion with the student, presented them with the evidence, etc. after they protested to you. That's a little different than my proposal, where in the case of protest you hand it off to the honor board immediately. I.e. the students should know that the only discussion is one where they risk suspension if they don't manage to prove their innocence. Also, from what I read, you actually sent out an email inviting students to come talk with you. Hard to see what other outcome there could be than students coming and taking up a lot of your time.

Think about it in terms of incentives and scarce resources. If the students know they can come and protest to you with no additional consequences, they will certainly do so, guilty or no. Everyone has heard the story of merciful teachers and cops that don't give a ticket if you cry. At worst, they are out two hours, and at best, they may get a higher grade with very little work. Basically, your time has become a commons whose use has no real cost to the individuals taking advantage of it, but from which they believe some value can be extracted.

The economic solution is to make sure the time costs something, so that the students will consider whether there's really enough utility in protesting to make it worth the cost. The cost is that if they protest, they run the risk of suspension in the event they are actually guilty. It should be obvious to students that this will be the likely outcome if they do protest.

Let me know if I'm reading you wrong because I really am curious if students protested even though any protest would result in an immediate referral to the honor board. Also, thanks for fighting the good fight even though it got you screwed in the end. We need more folks like that.

Oh, I didn't mention the one other advantage this approach has. If you quickly and forcefully deal with students who have violated class policies, I think there will be less emotional "splash damage." It's the same way a parent should not draw out a punishment over a long period of time -- make it hard, get it over with, and wipe the slate clean so you can smile at each other the next day.

When I detected 15+ cheating cases, I just asked permission from the Dean's office to notify students over email, and then direct them to the Dean's office for appeals.

So I did that, notified the cheating students they got a -30 (negative the points of the homework) and directed them to the Dean's office for appeals.

Well, it was very difficult to enforce the "talk to the Dean's office if you have a problem with my judgment." When the student comes in my office during office hours, I cannot say "I do not want to talk to you, get out of my office". Yes, I could do it, in theory. Hard to do in practice. Would I physically push the student out of my office?

Of course I would not advocate physically pushing the student out of the office.

> Instead, I sent an email to the class. I just said that there were cases of plagiarism detected and whomever cheated, could come and find me. For the rest, I would report the case . . .

I guess I just read this as an invitation to come and discuss the matter with you. And I understood from this that any who didn't come would be referred. If I were a student and reading this paragraph, I would make damn sure to speak with you about my indiscretions. That is the exact opposite of what I'm proposing, which is that you only refer students to the dean if they do come and speak with you.

Perhaps you meant to convey something different than what I'm getting from the blog post, if so, sorry for misreading.

> When the student comes in my office during office hours . . .

Once again, I've never been a professor, although I did TA for a while when I was in college. That said, I had an expectation that my office hours would be utilized in some way or another by students. I would propose prioritizing any student that wants to ask about something other than their cheating conviction. For students who want to talk about the cheating, just say, "If you really believe you did not cheat, we can discuss the evidence. But that will only happen at an academic integrity board hearing. If they find you innocent, I will regrade your work. Think about it and let me know by email if that's what you want to do." And then just refuse to talk about it.

Again, you're the professional and I'm the backseat driver. You know more about how this works than I do. This is simply how I imagine it would go, and although you've disagreed with me several times I still haven't gotten the impression that you did what I'm proposing.

+1 on the office hours comment.

In fact, I would argue that office hours is NOT the proper venue to discuss these matters anyway. From my experience, the purpose of office hours was to clear doubts and further understanding of the class material. I would've been extremely pissed off if I came to office hours with a legitimate question about the material, only to waste my time waiting on a bunch of people arguing about cheating.

Well, for non-office hours I can always say to the student that they cannot come in, as I have other things to do. There is a legitimate excuse not to even start the conversation.

However, during office hours, any student can come in and discuss class-related topics. I cannot prevent students from entering my office, just because I believe that they will want to discuss their cheating penalty.

In my law school, everyone is graded on a strict curve and honor code violations are handled first by a board of students. Does wonders for reducing cheating.

This has the problem of false positives, and an assumption of guilt. In my experience (at the Naval Academy, so maybe a little different), honor boards were designed solely to award punishment with no realistic chance of presenting evidence in your defense. I imagine that most schools are less strict, but still expect the professor to have talked the matter through with their students before a formal inquest.
Were you actually involved in the honor board at the Naval Academy? If so, I am wondering: is the honor board really only designed to punish, or were the only cases that made it that far so egregious that guilty is the only likely verdict?

Of course, I think I would only refer students to the honor board if it was blatantly obvious they were cheating, and they opted to refuse my "warning" punishment.

The board was not "designed" to punish, but that was always the practical outcome. Something around 90% of cases resulted in punishment while I was there.

Basically, a group of students is selected to oversee the trial. They are repeatedly instructed that they must issue a guilty verdict if a preponderance of the evidence (51%) points that way. An overseeing officer (captain or admiral) supervises the proceedings and assigns a punishment after a guilty verdict. This combination creates a strong expectation that students will issue a guilty verdict. (If this does not make sense, then you have not been around "real" authority and I cannot succinctly explain.) For juniors or seniors, punishment is typically expulsion and a $100,000 fine to cover training expenses. For underclass, it is typically a six-month probationary period (this is closer to a jail sentence than a normal college probation).

In some respects, the Navy is an exceptional circumstance. Most people would rather have lots of innocent people be punished than have a potential cheat graduate and be placed in control of nuclear weapons. Still, I have seen lots of innocent people punished (or guilty people punished way too severely) to not be skeptical of a system that has any chance of going this direction.

As for personal experience, I was never accused of an honor violation, but I testified at honor hearings for friends. In my opinion, both were unfairly convicted and punished. All midshipman get training on the procedure at least once per semester, and it is severely indoctrinated in our version of boot camp.

"However, all this wasted time, and all this aggravation, wouldn't be necessary if all the other professors were doing it too."

This is a classic problem in economics: what to do if an entire group of people would be better off doing something, but you doing it alone makes you worse off? In his case, working on cheating on his own results in lower evals and a more contentious class environment. The incentive, as he points out, is not to bother.

I wrote about incentives in a longish post about grade inflation (http://jseliger.com/2011/04/02/grade-inflation-what-grade-in...) that comes to a similar conclusion: instructors are rewarded more for good evals than they are for grading harshly (or, for that matter, pursuing cheating). So we get situations like the one described in this post.

> 22 cheats out of 108 is big

Looks like standard 80/20 to me, nothing surprising.

A little tangential, but I think this post outlines another argument for the "higher education bubble." Is 40k a year worth learning how to effectively plagiarize?
I have taught (as a PhD student) similar material and this is no surprise to me. But then, is it realistic to expect undergrads to turn out a thoughtful piece on LTE and 4G comms? If it is a technical comparison, sure, but even if you don't plagiarise your sources what are you really doing? You're going to read some articles on the internet, form an opinion, and rewrite that stuff in your own words. So long as they are learning, what's the difference?
Holy crap. They let so many people get away with copy-paste assignments, and they call themselves a postsecondary institution? That's fucking horrific. Where I'm from, a single sentence similar to one of your sources is marks deducted. A paragraph puts you on academic probation. Anything bigger is a bus-ticket home.
Yeah, I personally couldn't believe he had people copying entire articles into their paper and simply let it slide with a lecture on how to source articles.

I've always tried to agonize over drawing some unique conclusions from a variety of source material. Looks like the more efficient method would have been to just reword the wikipedia article.

All of the stories about education bubbles, unemployed graduates, etc, seem to make a lot more sense when you see data like this.

I think you are right in your comment about education bubbles. Cheating as blatant as this could be a sign that many of the "students" are either unqualified or there for the wrong reasons.
Agreed. Anyone caught plagiarizing so blatantly should be expelled immediately. It is simply a waste of time to coddle people who should know better.
I remember doing some work on an essay with a friend of mine over the phone. There was one particular sentence he came up with that was absolutely stellar. I know it was original because we were working from the same text and discussing it over the phone - I was there when he came up with it.

When he got his essay back, this one sentence was circled in red with the comment "If you're going to plagiarise, be less obvious about it". He wouldn't go back and protest (he was pretty laid back) but I imagine that the rest of his essay didn't quite shine like this sentence did...

This happened to me in English comp. I decided to make the most of the class by really studying style. I turned in three papers utilizing different author's styles in my own way: H.P. Lovecraft, Hunter S. Thompson, and Henry Thoreau. I learned a hell of a lot but was told that I cheated. I told them I would sit after class and write a paragraph or two of each style for them. They said it wasn't necessary as they could 'tell', and that since they couldn't prove I cheated, the highest I could get was a C.

I almost quit college over it. That aside, the amount of cheating in my engineering courses was high. There was only a 10% grad rate within 4 years and 16% total. I think it was the top 10% and cheaters that could graduate.

There certainly is such a thing as being too aggressive in trying to detect cheating. It happened to my dad once but he cleared it up by re-doing the problem from scratch in front of the teacher.

I think it's absolutely critical that any accusation of cheating allow the student to respond, preferably to a different teacher if the original teacher still thinks they were cheating.

really studying style

I want to do this. How did you go about it?

Where I attended college, you get a year's suspension for getting caught copying a sentence without citation. Anything as egregious as this presented would've meant a class full of suspended students.
I'm sure that was the policy, but how often was it enforced? Most universities have draconian policies against cheating that are never enforced, except in the most egregious cases. It's extremely rare for any school to discipline as many people as this; when it does happen, it tends to be national news.
28 students last year (out of about 4,000) were reported. 17 were suspended, 7 got probation, 3 were found not responsible, and 1 had the allegations formally rescinded.

This is roughly consistent year-to-year.

Unless your school is dramatically different from other schools, you've just provided very strong evidence that only a tiny minority of actual violations are pursued.
The "were reported" is key. Who knows how many professors pulled a promising young student aside, gave them a stern lecture, and a second chance.
That's also the equivalent of saying "a single line of source code identical to other source code is copyright infringement". Sometimes it is, sometimes it isn't. Sometimes there are limited ways to express obvious ideas, so I don't get how such a hard-line stance helps anything.
> Sometimes it is, sometimes it isn't.

This isn't code, these are written assignments we're discussing. English is pretty damn flexible, and nobody gets suspended for "Abraham Lincoln died in 1865." There's no point invoking degenerate cases to argue against a policy. That's just silly.

When a nontrivial sentence appears both in an essay and in one of the listed sources, the Wikipedia page, or a top Google hit for the subject, you can draw inferences. If you can argue that you just happened to write:

> However, just six days after the surrender of Confederate commanding general Robert E. Lee, Lincoln was shot and killed by Confederate sympathizer John Wilkes Booth at Ford's Theatre in Washington, D.C.

just as it appears on Wikipedia at present, and convince your peers it's more likely than not that you did, then you won't be punished. Not unsurprisingly, such pleas typically (but not always) fail.

Where I'm from, a single sentence similar to one of your sources is marks deducted

Sounds like the purpose of the class is to teach people to use a thesaurus.

It is a deterrent. It is often easier to come up with an original sentence then sit around with a thesaurus.
Panos, I wrote you a long response on your blog.
Once the author decides that the academic standard allows copying and pasting, it ceases to become cheating - and he has joined those for whom the term "academic honesty" has lost all meaning. Seriously, when 44 hours over the course of a semester is too much work to uphold a minimum standard, the issue is not confined to students and the author has no moral high ground because they have abandoned the tough part of their job and are doing the grading equivalent of cutting and pasting.
I think you seriously underestimate the emotional toll it takes on a person to go through 44 hours of "I know you cheated" with dozens of students. Merely calling that "work" - as if it's equal to prepping for lecture - is not fair.

I think you also ignore the chilling effect this had on the class itself. It's quite possible that the students who did not cheat experienced a worse class because of the change in atmosphere.

I had to do this once, when I TA'd. It's a seriously hard talk to have.
If you are molly-coddling the students, then I suppose it could take a lot of time. An email with the Turnitin report would take about five minutes - which is about how long it takes for my spouse who teaches courses online to handle plagiarism.

Setting the expectation for academic honesty in the syllabus and directing students to university policies is more than enough. In any event, it should just be handled privately. There's no reason to jump up and down and hold your breath in front of the class.

As for confronting students, different schools have different expectations. As others here have pointed out, this school may expect professors to try to work out cheating issues locally first. I can't say.

Regarding your second point, if any one thing becomes a trend in a class, you bring it up with the class.

I doubt any school has a policy which does not allow every incident of cheating to be reported and handled through established due process procedures. Administration may prefer molly-coddling of the ATM's, but the written policy will almost certainly not require only reporting the third offense.

As for your second point, preaching to the choir is a waste of time and just makes them uncomfortable (as this case points out), the come to Jesus talk is a one on one affair.

Why do you assume that everyone who shows up to class is "the choir"?
In the example from the article, 80% of the class was presumably not cheating - so even if only half the class shows up for lectures the scolding will not be applicable to the majority of the students. Of course, if there is any correlation between lecture attendance and academic integrity (which one might suspect to be the case) then the majority becomes greater. In other words, the ill consequences cited in the article may well be a part of the author's choice of scolding the innocent along with the guilty. Seriously, at the point students are sitting in a university classroom - they all know what blatant cheating is and have either decided to do their own work or cut and paste. Going over basic citation requirements in class is more appropriate for junior-high school English.
scott_s is right. Enforcing cheating policies isn't as impersonal as enforcing parking laws. You can't just leave a citation behind and let the students and administration handle it. The professor will be involved.

There's also the aspect of a student being falsely accused of cheating. I was unfortunate enough to have experienced this during my college career. A fellow student, whom I didn't know outside of class, copied my answers exactly on a German exam. I don't know why he did this, because there were only 15 students in the class and the professor knew us all fairly well. To think the professor wasn't going to notice was a stupid assumption on his part.

I was called in to her office and shown the two tests. The answers were the same down to the punctuation even. It was clear the other guy was very bad at cheating and probably did it out of desperation. I was initially shocked and feared I was going to fail the class despite my innocence. She had to refer the incident to the honor board due to university policy. When I left her office I was so furious that I looked up where the other student lived because I wanted to fight him. But I took a walk, cooled off and decided against it.

I was ultimately cleared by the board and there were no marks on my record. After the proceedings were over, the professor apologized to me and said that she never believed for a moment that I had cheated, or that I had helped him cheat. She pleaded with dean to avoid sending the matter to the honor board, but she had to follow policy.

She said she never had any cheating incidents in the past, and that it was personally distressing for her to handle the situation. It was definitely stressful for me as well.

What your case shows is that the due process worked. If the professor had called you into the office and said, "Instead of handing this over to the honor court, I am going to deduct 30% from your score," that would have been far more unfair and built far more ill will.

To put it another way, a professor should focus on teaching and let those tasked with investigating cheating and listening to excuses sort it out.

And yes it can and should be as impersonal as a parking ticket. Cheating is a simple violation, and it behooves a teacher to forgo emotional investment in each case. Avoiding interrogations and Perry Masonesque cross-examinations would seem like a good way to avoid such an investment. When 1:5 students in a 100 person course is doing so, reporting cheating is a purely administrative matter of the same sort as turning in low grades for poor students - which hopefully is something the author still does not find to be too much bother.

Professors often are involved in the official process. Often they have to provide evidence at a hearing. They don't just throw the case over the administrator wall.
It is not a matter of throwing it over the wall. Administration can conduct the Spanish Inquisition more effectively than the professor.

A Turnitin report as cited in the article would be about as much evidence as would be needed. Particularly when Turnitin is the institution's official means for combating plagiarism...not to mention the level of matches described in the article would make it appear open and shut.

Yes, it might require some involvement from the professor - but the implications of complaining that such involvement is too much work is the basis of my criticism of the author's position.

Suppose it's a 12 week term: 45 / (12 * 32) = 11% If it's a 14 week term, 45 / (14 * 32) = 10%

So at best, you're looking at 10% unpaid overtime for a job that already requires a lot (maybe up to 100%) unpaid overtime.

FYI, I get paid to teach 17-20 hours a week, but with prep time and marking it ends up taking about 30-40 hours a week.

What I don't get is why he spent all that time on it. Catch someone cheating turn them in, no need for the in office histrionics, or long winded lectures about how to site sources.
Because the cost of being wrong[1] or of leaving doubt of guilt could well be a lawsuit or administrative action. A student who gets expelled or suspended for cheating loses a lot of money and has a very, very serious black mark that'll follow them for years. This (a) is not something you want to inflict incorrectly[1], and (b) makes the unconfessed student desperate enough to lash out in a lot of ways.

[1] - If your method is 99.9% accurate, you've got a 50% chance of a false positive after 700 submissions, which for a 100 person class is a milestone you could hit in your second semester.

I suspect that, a student who gets expelled for cheating has certainly gone through administrative due process well beyond the professor's office, and had ample opportunity to explain the 99% match to uncited sources.

By your logic, one could make the case that academic standards should never be upheld - 700 submissions is arbitrary and could just as easily be 7000 or 7,000,000 and the same rationale would apply.

At every university I have been attended(not that many) a report of academic dishonesty went to some sort of university investigation process to cover any sort of professor malfeasant(and university CYA). Therefore the professor should do his due diligence but beyond a shadow of a doubt isn't necessary.
If I was him I would at least write a letter to the department of Academic Affairs (or whoever handles cheating) informing them of the way he was penalized for reporting students. They, if anyone, are the ones with an incentive to fix that problem.

I just have to share my favorite cheating story. And just to let everyone know, this occurred in 1976 when I was an undergrad EE. I wanted to take an elective that was an “easy A” and everyone said, oh, you have to take music appreciation, very easy A. Cool, so I took the course. The basis was that you were supposed to go into listening rooms where there was a library of classical music and become familiar with the pieces and would later be tested on them. Back in those days, recording were on these large round vinyl discs called “records” hee hee, long time ago. I would go to class and this doddering old professor with thick coke bottle bottom glasses would look at the record place it on the turn table and it would start playing and everyone’s hand in the class would go shooting up and they would immediately know what it was. Well, I was dying in this class, I was spending more and more time in the listening rooms and getting no where fast. I felt like the stupidest person in the world. Until finally someone in the class clued me in. They showed me their notes; which went something like this: “blue label with red writing, Bach”, green label with yellow writing and furly loops around, Beethoven”. You get the idea. They were keying off the labels and the poor old professor did not have a clue. Now, I was faced with a real moral dilemma! On the one hand, I had been spending tons of time in the listening room and there is no way the others in the class could catch up with me so if I told on them, I would get and A and they would all probably fail. But on the other hand, if I joined in with them and also cheated, then we would all probably get A’s. What would you do?

If anyone responds to this post, I will tell you what I did in a later post.

isn't this why you have closed book exams?
Open-book, open-notes exams are harder to cheat on. There's no point to smuggling in notes when you can carry them in openly.
When I was in college, people would go to the "bathroom" during the middle of the exam, and then they'd actually wander outside, call their roommate, and have them read off the formulas needed from their textbooks. The invention of cell phones was a huge boon to cheaters.
When I TA'd, I took a hard line on any cheating I detected. Basically it was a 2-strikes approach.

I didn't use turnitin or other mechanisms. I figure, if someone is smart enough to cheat well enough that it's not detectable, it's okay to pass that person. It's not "great", but it's not unleashing a total disaster onto the world.

The cheating I detected was usually because those students were moronic. I am not talking "slightly different". I'm talking, copy-pasted from prior semesters, with 1 modification: the name. Or copy-pasted from the other person in the class with 1 modification.

You think that's bad? I had a pair of assignments for which the output of `diff -u` was less than 10 lines long.
With prompt given for the assignment, I'm hardly surprised by the amount of plagiarism.
Seriously. I hated classes that had stupid assignments. Personally, I opted not to do them at all because I didn't want to cheat. I was fine accepting a B in a class to avoid these assignments. Eventually, this bit me in the butt when applying for grad schools (not severely, but reduced funding), so I totally understand why people would copy them to keep their grades from falling.
"Instead of the usual evaluations that were in the region of 6.0 to 6.5 out of seven, this time my ratings went down by almost a point: 5.3 out of 7.0."

Way to bias ratings. Students caught cheating should certainly not be rating the professor who caught them. I won't say "problem solved", but that would make a fine start.

From the sound of it his honest students probably rated him lower because he wasted a lot of lecture on his forays into cheater cheater chicken eater land. I know I would have, lectures about how many people cheated on the last assignment would bore the crap out of me.
Why not have the grade of papers be multiplied by the inverse of the plagiarism score? For example, your first author would get a maximum of a 3% grade on his paper. Of course there are false positives to think of as well, but this would force the authors into more and more original content.

The very first assignment I did in college was my own, some code I wrote for a programming class. I turned it in, but my friend was in the class didn't do his assignment. I figured it was a basic enough problem and I really just turned in the assignment for him. We both got slaps on the wrist, but I never blatantly plagiarized again. I'm not saying I've never reused a sentence from another document on occasion, but usually it was either cited or more unconscious.

The big bummer in college was exactly what he talks about though: the propensity for students in some sort of group to help each other out. The fraternities and athletes were always the worst offenders. For the general eds, everyone in class knew that so and so had a copy of this professors test which he barely changes from year to year, or this fraternity keeps all their papers from previous classes categorized(!) so other members can use them, and that sort of stuff.

I'd really rather not have my grade depend on a completely non-transparent tool that I have completely no access to nor can refute its accusations.
Because Turnitin is pretty terrible software and there are a lot of false-positives. I remember having to "explain myself" for an essay I wrote where what was copied was direct, cited quotes. It uses word pairs sometimes and will highlight any uncommon phrasing that someone may have used in the past.
