Prof Gives Lecture to Prove He Knows Students Cheated; Over 200 Students Confess (thoughtcatalog.com)

But was it really cheating? Some students have pointed out that the professor said repeatedly that he composed the tests himself. Given that, then plausibly, using example tests from other sources would be a legitimate preparation method. (For example, the SAT doesn't penalize people for reviewing lots of practice tests, because it's assumed the actual questions during a real test will be novel.)



Now, it was probably common knowledge from prior semesters that this professor's exams were from the standard test bank. So those reviewing test bank questions may not have had pure motives in their study strategy. But it makes it less cut-and-dried, especially given that the students may have memorized (for example) 5 answers to potential questions for every 1 that happened to appear on the test. At some point, knowing all the answers to all potential questions is knowing the material... or else the whole idea of formulaic tests is bankrupt.

I second that. Using the same questions for a couple of years and blaming the students that they learned the answer to those questions?


I guess an important question is whether this test bank is supposed to be accessible only to instructors. Presumably a test bank would contain enough questions for several tests, so it isn't necessary that there were any repeats from previous semesters.

I think that if the instructors are allowed to be lazy enough to use a test bank, then students can't be blamed for using it as well.

I'm shocked to see so many pro-cheating comments get up-voted on HN.

Why shouldn't a community of professors be able to cache and re-use questions? The bank should have been secured, yes. But caching/pooling is on ethical ground more solid than that of cheating.

Why shouldn't a community of students be able to cache and reuse responses to cached and reused questions?

Laziness begets laziness. I don't see how you can claim it's ethical for teachers to forfeit 1/2 of their job to a question cache. Cheating in this definition is using someone else's work to benefit yourself and by definition the teacher cheated too by using someone else's questions to form "his" alleged test. IE benefiting himself by not having to do the actual legwork to write his own test.

I don't think HNers are pro-cheating, I think we're pro-effort. We all work our fucking assess off at things we love, it's a little disrespectful for some shit-ass professor to claim his students are cheating by using HIS method to save time and effort. I call that his students learning a little too much from him.

Cheating in this definition is using someone else's work to benefit yourself and by definition the teacher cheated too by using someone else's questions to form "his" alleged test.

That is a bizarre definition of cheating and shows that you don't understand the point of testing at all. The point of testing is to measure (perhaps crudely) students' understanding of what they are supposed to learn in the class. The teacher's job is to administer a test that does this effectively, and if a test bank helps him do his job effectively, he should use it. In this case as in so many others, it is perfectly appropriate to use someone else's work as a resource to improve one's own work. In fact, as long as one is honest about attribution, this is highly desired. Test materials are unattributed, and sharing is the assumption, so it isn't dishonest or unprofessional for a teacher to draw from a bank of questions when composing a test.

(Students are claiming that the professor said he created the tests himself, but even if he drew the questions from a test bank, he was still deciding which particular facts and concepts were most important to test. Maybe he said he composed each question himself -- that would be a lie. However, it wouldn't be a lie for him to say he created the tests. It is standard for teachers to compose their own tests but unusual to aim for originality on each question, unless it is an essay test with a small number of questions.)

Why is taking a test different from creating one? If the point of the test was to create a big stack of papers with the right answers on them, it would be appropriate for the students to collaborate and use any resources to accomplish that goal. However, that is not the point. The point is to measure each student's understanding and help decide how much credit each student should be given for their understanding of the material covered by the test.

When students cheat, they subvert the purpose of testing. By hiding their cheating, they dishonestly claim credit for understanding they did not achieve. The professor's job is to administer a test that will test student's understanding. It is not his job to demonstrate his independent powers of test-writing.

So is any studying for a test acceptable, since it modifies the understanding you had before studying? I mean, we have to assume the materials being studied will contain the right answers to the questions on the test.

Are lecture notes cheating? The professor is likely to include answers to test questions in his lectures. I've had professors use in their lectures the exact questions — literally, not a word different — that would appear in the next test. Was I cheating by attending the lecture and learning what was taught there?

Where do we draw the line between smart studying and cheating if the professor makes no effort to keep the test questions a secret?

So is any studying for a test acceptable, since it modifies the understanding you had before studying?

That's the whole freakin' point: the test is supposed to measure your understanding. The honest way to improve your test scores is to improve your understanding of the material. The professors administer tests, the students study and learn, this is the intended way of things. This is the way traditional college classes work, and if you want to go to college and get grades, then you have two choices: study and earn your grades honestly, or lie and cheat.

Everybody encounters a class that they end up cutting corners in, of course. For example, you can try to predict what topics will be on the test and study those most carefully. You can try to predict which problems will be on the test and learn to solve those. The question is, are you actually trying to learn something the class is designed to teach and hoping that what you learn will serve you well in the test, or are you trying to improve your score without learning anything useful? Drilling pattern recognition of potential test problems is not learning. That method relies on your mind's ability to recognize specific verbal patterns and associate them with other verbal patterns. It has nothing to do with understanding the material. From the perspective of learning, it's a complete waste of time.

By the way, I agree with you that professors should lift questions and answers from their lecture notes with great restraint, for exactly the same reason. One or two here and there to reward diligent attendance is fine, but if it's a significant portion of the test, then the professor is essentially conspiring with the students to inflate the test results by relying on familiar phrases or diagrams to trigger students' memories of how to answer a particular question. That's actually a good reason for teachers to share testing materials: will students still understand the material when their professor's particular phrasing is not present? I heard a student complain he got a physics problem wrong because the professor always said "inclined plane," but the test problem talked about a "slanted floor." Clearly the student did not understand the material and was relying on verbal associations; no matter whose fault it was (the student's or the professor's) it was good that the test result reflected the student's lack of understanding. In the real world, an inclined plane does not say to you, "Hi there, I'm an 'inclined plane.' Does that ring a bell?" Or if it does, it will probably not use exactly the same words your college physics professor used in his lectures! That's a very good reason for a professor to use problems written by someone else.

"I don't see how you can claim it's ethical for teachers to forfeit 1/2 of their job to a question cache."

Exactly 1/2 of a professor's job is constructing exams? What part goes to lecturing and preparation? Office hours? Grading those exams and class projects?

"Cheating in this definition is using someone else's work to benefit yourself..."

No, cheating is gaining an unfair advantage in some kind of competition by violating the clearly specified rules. Your definition certainly is not how the word cheat is commonly used, and I have no idea where you came up with it.

I think you are thinking of "plagiarism," which sometimes intersects with cheating, sometimes not.

The students are accused of plagiarism by a teacher who is essentially plagiarising test questions. The students are accused of cheating - I contest that the professor is too.

I realize that accusatory turnabout is a fun exercise, but what you have here only meets the form of turnabout, and not the substance. One of the key indicators that you've gone off the rails: your turnabout necessitates conceptual contortions in order to make a false equivalence.

In your post above, you falsely claim that the students are being accused of plagiarism. They are not. While plagiarism can be a kind of academic dishonesty, it is not the particular kind of academic dishonesty at issue here. Then, to complete your false equivalence, you try to re-frame the de rigueur practice of drawing test items from an item bank as plagiarism, which is just laughable and ignores both the purpose of the test instrument and the different roles of student and teacher.

I contest that the professor is too.

The word "contest" in the above context means "to oppose as mistaken or wrong". So your sentence literally reads that you dispute that the teacher is also cheating. Clearly you have been arguing the opposite.

I think it might be time to give it a rest.

Why shouldn't a community of students be able to cache and reuse responses to cached and reused questions?

Call me old fashioned, but the roles of "student" and "instructor" make all the difference here to me. Although I'm not surprised that youngsters these days feel entitled to this behavior. Entitlement runs deep in modern American youth.

Are students entitled to lecture, assign homework, and hand out grades too?

I think entitlement runs deep in American adults who are teaching it to the youth.

You blatantly feel that teachers are entitled to perform with a different ethics set as their students, which is personally abhorrent to me. If you have a problem with students cheating at their job of studying, you have to have a problem with teachers cheating at their job of teaching. It isn't an ambiguous issue, it's rather clear cut. If a student cheats they risk expulsion, however the teacher cheats and there's not even an eyelid batter - I call that a society of entitlement.

Applying the word "cheating" to the teacher here is a re-definition of words worthy of Humpty Dumpty. The plain meaning of cheating is to gain an unfair advantage over others in a competition. The teacher administering an exam is not a competitive act on the part of the teacher.

I am deeply disappointed that so many here on Hacker News are resorting to such poor sophistry to defend a very simple, cut and dried case of cheating, and that so many are lending their approval through their up-votes.

FYI you don't need to post essentially the same comment twice.

Point taken. :)

I may have missed something. What, exactly, is the ethical violation alleged against the teacher here?

I saw the video made by the students that attempts to "prove" that the teacher said he wrote the test questions himself, but it makes an extremely flimsy case:

1) It's a statement made on Day 1 of class, long before the midterm test

2) He only said that he creates the test, but does not state that he authors the questions. One algorithm for creating a test is to select questions from a question bank, so this statement has no evidential value.

3) The only remaining "evidence" in the video is a statement where he said that "he may write" a question that even he may not be able to answer. It's entirely possible that he intended on Day 1 to author the questions for the midterm, but ended up using the above method for creating the test by the time midterms rolled around.

The students are very eager here to turn the tables here and display some righteous indignation to deflect attention back to the instructor, but they haven't yet managed to make a compelling case.

I am no pro-cheating (as I said in the other thread on this) but I don't see this as cheating.

"Why shouldn't a community of professors be able to cache and re-use questions?"

Well, the reality of having Greeks / Clubs that maintain a library makes this difficult, but even worse is what it actually says about the class and the teacher. If the class is so cookie cutter than why not just have videos from the publisher and an online test? What has this teacher learned from previous offerings? A test is a teacher's summation of the important points taught in the class. It should be improved and modified to account for new information and improvements in the teacher's teaching style. Cookie cutter tests lead me to believe he put the same effort into the lectures. I question anyone who probably spent more time proving cheating than creating the test in the first place.

Even assuming the teacher was lazy, or plagiarized the test, that's simply no excuse.

Anyone who sees questions that they had early access to from some special source (a source not available to all students) has a clear ethical responsibility to inform the teacher that they had special access.

It might be slightly ambiguous when, by happenstance, a few questions are the same or similar. But when all of the questions are the same, what are these students thinking? They know that other students are seeing these particular questions for the first time even if they studied intensely.

Students can choose how they learn. But the professors choose how the students are tested, and this test was clearly compromised due to student dishonesty. You can throw other factors in if you want, but dishonest is dishonest.

So, the crux of your argument is that these students had a "special source (a source not available to all students) has a clear ethical responsibility to inform the teacher that they had special access."

I take it that you believe members of Greek / Clubs on campus that have old tests are dishonest (not everyone is a member)? A student buying a study guide that finds the teacher just used a sample test from the study guide is also dishonest?

I guess my big problem with your reasoning is that I can make a bunch of honest decisions in my studying for a class and then become dishonest by the dishonesty of a teacher.

"I can make a bunch of honest decisions in my studying for a class and then become dishonest by the dishonesty of a teacher"

The thing that I think you are missing is that it's all about mutual expectations.

It's the same thing if you take a picture of a TV and put it on eBay for $100. Then, someone buys it and you send them the picture of the TV rather than the TV itself. That's totally unethical of the seller, even if they never say that they are selling a TV explicitly. The buyer expects to receive a TV, and the seller knows that the buyer expects to receive a TV, and proceeds knowing that the buyer's expectation is flawed. Maybe the seller really likes photographing TVs as a form of art, and thinks that their work is worth $100 per print (honest so far); but that doesn't matter because they knew the buyer had other expectations, and did not inform them (dishonest now).

The fact that many students didn't have access to the test ahead of time, and that the students received the test surreptitiously (as another comment said) is evidence of the teacher's expectation, and of the students' knowledge of the teacher's expectation. The fact that students knew this expectation was flawed means that saying nothing is dishonest.

It is all about what a teacher or other relevant authority says is okay to use. If the teacher explicitly says not to use old exams, then the members of Greek clubs are cheating if they use their archives. Similarly, if a publisher's test bank says that students may not use it, then it is cheating if students use it to study.

Well, the reality of having Greeks / Clubs that maintain a library makes this difficult

I was the president of a fraternity at this university. There has been no decent test bank for quite some time. However, I've heard that some of the archives from the international clubs are quite robust.

Because using previous tests is a common (and presumably ethical) method to study for previous exams.

As noted in the previous thread, it might have been a good idea for the students to have said "Hey, we've seen these questions before." But the professor using a bank of test questions changes the situation from "a bunch of students stole the test" to "the professor maybe should have used questions that people didn't have ready access to."

On the other hand the prof shouldn't say that he makes the tests himself if he does not. If the professor told you that he'd make his own test then studying from existing tests isn't cheating, right? It's the professor passing others' work off as his own. This video looks like a professor trying to save his own ass by blaming it on the students.

You could say the students that used this test to practice should have informed the professor when they noticed that the test was identical to the one they practiced with. However, if you look at how defensive this prof is, that would have been quite risky for that student. You would risk being accused of cheating. So instead somebody did it anonymously.

"You would risk being accused of cheating [if you informed the teacher that you had special access]."

The epitome of rationalization.

Academic honesty is taken seriously, and there are third parties that evaluate the situation objectively. If you simply say, "I didn't do anything that I thought of as cheating, but today on test day I realized that I had an advantage that I wanted to inform you about," there is zero chance of permanent consequences.

"So instead somebody did it anonymously."

Why didn't everyone then? Maybe those few people are honest, or some approximation thereof. But what about the other ~190 that didn't?

Just feel I should point out this line (and nothing else! this is a volatile line of discussion, and I'm not aiming to perpetuate it):

>... there is zero chance of permanent consequences.

Bull. Faculty are just as petty and lazy (ie: human) as any other person. There are plenty of instances of teachers saving their own asses by lying enough to get away with it, and with them wielding their mighty tenure in unethical ways.

Damned if you do, damned if you don't, if you don't know the teacher very well. Odds are certainly on your side, heavily even, but it's far from "zero".

"However, if you look at how defensive this prof is, that would have been quite risky for that student."

Defensive suggests he acts like he thinks he did something wrong. He clearly thinks his students did something wrong.

What is it with this thread and using words to mean things other than their plain meaning in normal conversation? It's getting very Clintonian in here.

I was talking about his response when a student asks why all students have to retake the test even the ones that did not cheat (or I presume the student asked this I can't hear it clearly).

This is completely wrong. If the students are allowed to use the test bank questions, then it's ethical. If it's not provided to them, or they obtain it surreptitiously, then it's cheating. Practice tests are allowed for the SATs, but previewing the questions was clearly not allowed in this case. These rules are arbitrary, but real. Just because certain exams are open-book, doesn't mean all students are entitled to bring reference materials to all exams.

Rules matter.

PS - That's the difference between school and real life.

If it's not provided to them...then it's cheating.

The idea that students are only allowed to study from materials that are explicitly provided to them seems questionable. I would preface this with a statement of my own ignorance of the matter, if I weren't presently an engineering student.

I have never encountered someone who said "reading material given to you by someone other than the professor is cheating."

I think the intent was to say that if the professor had a reasonable belief that the test bank was secured and not accessible to students, then they probably should have had that same belief, and not used it as a source.

I don't necessarily agree with that.

Since the professor stated on the first day of class that he would be creating his own tests, there was no reason for the students to even consider the possibility that a test created by the textbook publisher would be used as the official test.

So if, for example, a student hacks into the professor's computer and steals the test-question to study from, this is OK as long as it wasn't expressly forbidden? I'm not saying they should only study from materials that are provided... but in this case they were clearly using materials that they shouldn't have had access to.

Some actions have default moral and ethical values. Hacking into somebody's computer is assumed by default to be bad — it would be bad even if they hadn't intended to use the test for their class. Most actions, such as reading a sample test, are not as clear cut.

If it were a process-oriented class, that might be justified. For instance, in a pure math course, you wouldn't want to read an off-syllabus math text in which the author proves theorems that show up on later problem sets or exams.

However, those sorts of courses are not typical, and it falls to the professor to make clear and explicit if external material is forbidden, and to explain why.

Since the existence of a test bank implies the exam was (mostly) multiple choice, the above concerns do not apply. There is no reason to forbid students from learning from external resources if your idea of testing them on their knowledge is giving them a multiple choice test.

The proper (and common) scope for restricting external materials is an individual problem set, quiz, or test. It's implied unless stated otherwise that you shouldn't get help for specific problems or questions from external resources, but it is almost never implied or stated that external resources are banned in the scope of an entire class. In that context, if you go exploring for materials and find something that helps you on a later problem set, quiz, or test, that's your reward for seeking out more materials to learn from.

Yes, it is really cheating. A publisher's test bank is very clearly not made for students to study from. The publishers warn students not to read them and try to make them inaccessible. In my experience, the professor almost always tells students what they can use to study from. Whether students can use past exams is almost always clarified - I wonder if a student asked in this case.

However, here the instructor has no way of knowing who cheated. He clearly made a mistake, knowing that using a test bank would make it easy to cheat. So, he should either let all the grades stand or he should point out the statistical anomaly and just make everyone take a new exam, which he did. I can't possibly see how students who didn't confess will be found out, especially if the exam was multiple choice!

No, I really don't think this is actually cheating. He handed out a test that, while claiming to be original, was actually from a standard bank provided by the publisher. This isn't a SAT or GRE that is standardized by an organization or the U, it is a test in a class that he claimed to be the author of.

What really annoys me about this story is he is covering his laziness / inattentiveness to his class of paying people and having "fun" doing mathematical analysis of his class to prove "cheating" instead of spending time creating a test. If he won't even put effort into original tests what effort does he really put into the class? Are all his class lectures equally canned? Would these students be better off with a video lecture series from the publisher and taking an online test? What value and insights is he bringing to the lectures. He sure isn't testing on those insights.

I will agree with you. I'm not familiar with these test banks, but if they are publicly accessible, what's the point in banning them? Here in Greece, all our university teachers encourage us studying any material we can find, even past exam papers, and most provide the papers themselves. We are also allowed to take the exam paper with us when we finish the examination.

If you're a teacher, it's part of your job to write novel test questions. If you can't be bothered to do that, you can't tell people "this is what I'm going to ask in the exam, but don't read it". This isn't even the minimum amount of effort to keep honest students honest.

As another poster said, studying an entire test bank is studying the material.

We both agree that the professor should have made his own questions. However, this does not get the students off the hook. They used a resource where the publisher clearly says: students, do not use this to study. So, this is clearly, without a doubt cheating. I'm sure that many students knew the professor would use the questions verbatim, making it even moreso questionable.

What if someone came up to you and said "here's a test bank man, the prof pulls the questions right off it!" Clearly it is unethical to study from these materials. Similarly, if the test bank merely says "STUDENTS: Do not use this to study" then it is also unethical to study from.

Nothing in what you say suggests that the students did not cheat. You say the professor was lazy. That statement in no way contradicts the statement "the students cheated."

To me, the morality of what they did is less interesting than the practical ethics of it. The assessment they gamed by accessing the test bank is meant to provide feedback for how well they are acquiring the material. Getting the answers from the test bank means they were more interested in gaming the system for the credential than they were in feedback about where they need to strengthen their understanding. That suggests to me that they're not really interested in the course material, and I wouldn't be interested in working with any of them in any context which used that material. That's an ethical failure. It could be a failure of the course and the educational system, rather than of the students themselves, but it's a problem, no matter who you assign the blame to.

If you've ever been to business school, then you'll know that most of the students clearly don't give a shit about the course material. I mean what kind of 18 year old kid would care about the pricing of a zero-coupon bond?

For the record, 18yo me would be interested in it. :)

Have you seen how degrees are used in the workplace? If you have then not caring about the material and only on your GPA and getting a degree is a very rational choice. Cheating only makes rational sense when a few letters and numbers are vastly more important than the knowledge that is supposed to be conferred by the degree.

In most large businesses knowing how to make pretty graphs that trend upwards infinitely is far more important than anything taught in business school.

> In my experience, the professor almost always tells students what they can use to study from.

No one have any say (if they have, they shouldn't) in what a student chooses to study. The student might choose to study from some cliff notes, class notes, books or test banks.

The professors, at best, can make a suggestion/recommendation which the student is free to ignore, because hell, he is willing to bear the outcome. It's his test scores that are going to be affected.

If the professor recommends a sub-par C book and I prefer K&R, no one can stop me from doing that. Similarly, if the professor suggests "Computer Architecture(Hayes)", and I think the book is a bit tough for me or I am not that interested in studying Computer Architecture, I will go ahead and use cliff notes or solve some test banks. A professor can't shove something down my throat just because he feels otherwise.

I don't really see why the professor is entitled to tell students what to read, or more importantly what not to read.

I agree with you, philosophically. But the issue is that if a professor or other relevant authority says "you cannot use X to study" and you DO use X, then you are definitely very clearly cheating. In this case, test banks are clearly labeled that they are not to be used for students.

What if the professor says not to review past exams, because he may use questions from them. You still say it would be okay to use past exams to study? Well this is similar - the test bank says: students, do not use this to study. Obviously the teacher should have made up his own questions, but the students definitely knew better ...

Isn't the whole point of schooling to know what's on the test? I mean if it was important to be able to do something with the knowledge then they'd focus on that instead of endless tests.

If a professor tells you to not do X and you do X you're very clearly not doing what he says, whether that is 'cheating' who knows. A degree is largely a check mark on a check box for a perfect little life of doing what you're told. Now, if people think that having a degree means X then they are free to do that and will reap the consequences.

Honestly, why should the students bother to come up with original work when the professor can't even be bothered to create original tests? Why is it not 'cheating' for the professor to use another persons test?

Obviously, what's on the test was taught in the class, so why not use an abridged format of the information that makes it unnecessary to learn information not relevant to the course? The test is the subset of the information taught that is relevant to the conferrance of a degree. To know more is to waste your time.

>> Isn't the whole point of schooling to know what's on the test? ... To know more is to waste your time.

In other words, you should do the bare minimum to get by. Well, everyone's motivation for getting a degree is different, and you are welcome to this opinion. However, if this is also your life philosophy, then I think you may be disappointed.

Now, I personally agree that this instructor was lazy. However, in a perfect world actually every single iteration of a class would use the exact same exam. This ensures that every student who ever takes the class is graded in the same way. However, some students retake the class and share exams, so this is not possible.

It's like if you're a magician and you have an awesome magic show. Why make up a new show for each new audience? If the audience is different each time, then your show is still awesome - even if it doesn't change.

If the students consider this material useful to study, it's unethical for a professor to deny them access to it. Making the knowledge harder to acquire is precisely the opposite of his job. Especially when the only reason is that the professor wants to be excused from doing the other part of his job by simply recycling an old test.

@Downvoter So you are basically saying the student doesn't have the right to decide what to read and what not to read? Since he enrolled in the university, he forfeited his intellectual independence and is bound by the whims of a professor?

What I suspect is that half of the questions on the test came from the test bank, and half were original to the professor. Therefore, the cheaters can be detected as ones who got the first half nearly 100% correct, and the second half maybe 50% correct.

Wow, just wow.

I never studied in college in the US, and I'm horrified that this is the standard. In Israel, we had the previous tests in the library, and the student union created a (for-sale) curated versions, all above board and perfectly condoned. The assumption was that memorizing the entire test-bank, containing hundreds of questions, was harder than actually understanding the material -- but that if you thought that was your best way to pass the test, go ahead and do that.

In fact, some professors explicitly encouraged memorizing proofs for all important theorems by promising that the test will contain at least one or two of them. Of course, usually they followed this by explaining that you're free to come up with your own proof, or memorize key points and manage to interpolate. I would recite proofs in the shower, to myself, every morning.

It would only be cheating if you got the actual test being used ahead of time (or, of course, consulted a confederate or disallowed materials during the test). It would not be cheating, and in fact, tolerated explicitly, to harass the professor by asking questions from test banks that you failed to solve, and getting valuable information that way ("it's not going to be on the exam, don't worry about it").

The professors assumed that anyone who puts that much energy into studying for the test deserved the grades they got.

tl;dr: In Israel, only stealing the tests or breaking rules during test periods was frowned upon: anything else was viewed as "studying really hard."

I think he was bluffing... but it obviously worked.

Some other threads (and news articles) mention a video clip in which the professor claims he will write the test himself. By doing so, this professor implicitly declared the test bank (and everything else on the Internet) fair game for studying from.

The students probably messed up big time by not reporting that the test was publicly available first, but I think we're missing some important facts and only seeing one man's edited version of events here.

That does not implicitly declare that a test bank is okay to study from, since it says on it that it is not for students. Any student would question to themselves whether they should use it. So ethically speaking:

1) Ask the professor before the exam if it is okay to use the test bank. He will say, of course not! Why do you have it anyway, it's not made available to students - are you trying to cheat?!

2) Astonished that the test bank was the exam verbatim (though I'm sure few students were), students should have told the professor that many students used the test bank, not realizing he would pull the questions directly from it. Of course, no one would do this directly since students aren't supposed to have the test bank in the first place ...

1) Many of the students probably received the test from their peers and did not know that it had come from a private test bank. I seriously doubt 200 people independently and individually broke into the same test bank, unless it was actually open to students, in which case it was as much fair game as the rest of the Internet. There are plenty of universities that keep student-accessible test banks and records of old exams (including the two I've attended), so many students probably assumed it was from that type of source.

1.5) Also note that the concept of a "test bank" that is supposedly inaccessible to students is not entirely common knowledge. We don't know how easily accessible and/or clearly warned this information was.

2) I already said that the students were wrong not to mention that they'd seen the test.

Even if you think it's fair game for students to have access to the test bank, at the point where they started to take the test and realized "uh-oh, I've seen every one of these questions before," they should have gone forward and admitted that they'd previously seen this material.

I agree that it's arguable before the fact that using the test bank is just studying. Once the students realized that they'd effectively gotten an advance copy of the test, deciding to benefit from it rather than admit it was unethical.

Another commenter here has already voiced the question about how so many HN commenters are apparently pro-cheating; I'll admit it's somewhat shocking to me as well. There is a (probably minority) group here that seems anti-higher education (or, said more fairly, anti-the present envisagement of higher education); is it possible that it's this bias showing through?

should have gone forward and admitted that they'd previously seen this material

Isn't that to some extent what the professor reports as happening? Both the anonymous test-bank drop, and the other 'emails' from students reporting that some peers had question access, are students blowing the whistle once they understand the whole situation.

Further, perhaps some of those talking about 'others' are being coy about their own involvement until they know how their study behavior, which they had previously believed was legitimate, will be judged retrospectively.

"I'll admit it's somewhat shocking to me as well."

Me too... I actually registered an account on HN just to reply. Society depends on honesty even in the face of complicating factors -- and if an intellectual community like HN doesn't stand up for honesty, that greatly disturbs me.

"There is a (probably minority) group here that seems anti-higher education"

I think most of it is more like a contrarian attitude. Some very smart people tend to pull in a lot of interesting -- though tangential -- perspectives and observations and then end up getting distracted from the fundamentals.

Cheating is cheating. Maybe the teacher or his teaching strategy was flawed. Maybe the students, at one point before test day, had honest intentions. Maybe some students were partially (or wholly) honest after the fact by alerting the teacher. But the rest of the students, who proceeded with the test even though they knew the test was compromised, were dishonest.

If this was such common knowledge amongst his students at UCF, then why was this the first time that the professor saw the bimodal distribution in the test scores? Why didn't his Summer class's test scores have the same distribution?

I think a lot of the comments in this thread are making assumptions about what the students did or didn't do, and might possibly be excusing some unethical behavior because of faulty assumptions.

As someone who works with data I can tell you that distributions can take on all kinds of unexpected shapes, especially when n=600. I think he's bluffing - the stats can't prove that anyone has cheated. That said, the deal he offered sounded pretty good when compared to the alternative.

I, as a non-statistician, agree that he was bluffing. If I were a student in that class with a high grade, cheating or no (because even the innocent may get accused and face the ostensibly severe consequences), I would be thinking "Hmm... Now how exactly does he plan on proving that I cheated?" Without a confession or third party who could reliably state that they know hypothetical-I was cheating, the possibility of actually proving misconduct on an individual level seems extremely remote.

I would love to hear some statistics folks weigh in on this. Or: speculation ftw!

My thoughts exactly. If I were a non-cheating student in that class, I would be very tempted to confess anyway, out of fear that I would be a victim of the prof's over-confidence in his statistical analysis. He mentioned being able to supply the dean with a list of people with 95% confidence that everyone who cheated was on the list, with no apparent concern for any false positives. The confession offer is pretty good in comparison.

"He mentioned being able to supply the dean with a list of people with 95% confidence that everyone who cheated was on the list, with no apparent concern for any false positives."

Right after that, he said that he couldn't be sure everyone on the list had cheated. He is saying that he thinks every cheater is on the list, but not everyone on the list is a cheater.

Right, that's not too impressive though, the class register would have everyone who cheated on it with 100% confidence.

That assumes that proof of anything is required. That's not usually how college disciplinary actions work.

At its worst, universities will sometimes assume a student accused of wrongdoing is lying, and punish the student based solely on the word of the faculty/staff bringing the charge. This happens in lesser cases where the administration thinks it can get away with it, and when the student is frightened of harsher sanctions that might be inflicted if the student asserts his or her rights and demands a full hearing process.

At its best (typically in more serious cases), the disciplinary process resembles a civil case (except instead of a jury, it's more of a tribunal) where the required proof is a preponderance of the evidence.

It's no wonder 200 students confessed. If I was in that class and I'd never seen the test bank, I'd have confessed too. It's been my observation that the disciplinary process is better at railroading not-provably-guilty students than punishing provably-guilty students. I would not want to take my chances.

Perhaps this was the first semester that what had been known to a few people, or whispered about, became widely known. Perhaps this was the first time a digitized copy of the test bank got widely distributed -- maybe even because the publisher's standards for selling the test bank got loosened.

At a smaller but growing scale, over several semesters, this tactic of using the test bank might not lead to any striking anomalies in the distribution... just a gradual rise in the average, and fattening of the above-the-median tail. For a while, that might convince the professor he's doing better!

(Also, while we see Summer scores for comparison, he doesn't show the prior Spring or Fall. Often Summer students are a different pool, who in this case may not have been privy to the same campus folklore. Perhaps there was evidence of the same tactic earlier, or another professor with a different exam style taught previously.)

Lots of speculation, I know, and I would need more information to assign levels of culpability overall. Were students specifically warned off using test bank questions? Did those who obtained the questions lie to the publisher to acquire them? How similar were the circulated test bank questions to other official preparation materials? Etc.

It could also be interesting to see, on the makeup exam with presumably all-new but similarly-difficult questions, has the average mastery gone up? Perhaps memorizing the test bank questions does have some persistent beneficial effect for understanding the material.

So, if it was known in previous semesters that a test bank was used, why such a large statistical aberration this time around? It seems implausible that 1/3rd of the class just happened to memorise the answers accurately, and indeed, the distribution suggests that another factor was in play this time around.

"So, if it was known in previous semesters that a test bank was used, why such a large statistical aberration this time around?"

What evidence do we have for the large aberration?

Are there older reviews of the professor available online that say his tests are easy or that he reuses old test questions?

He showed slides of a normal distribution for the previous semester's results, vs a bimodal distribution for the current semester - that's the aberration I'm talking about.

The first explanation for that that pops in to my mind is someone googling/searching/researching a question they saw in the exam that they didn't know the answer to and finding it as a part of a test bank, then realising all the other questions in the test bank were on the exam too. He tells someone, they tell someone and next semester 200 students have a copy of that test bank.

I'd like to know how many problems the students expected to encounter verbatim or near-verbatim on the test.

Were they hoping to see a few identical or similar questions? That would seem to be the typical scenario when you're studying off old tests or, for that matter, the homework problem set. If any show up on the test, great. If a lot show up, you're lucky.

Or, did they think it likely that the studied material would make up half or more of the actual test?

At about 12:47 into the video he mentions that the makeup exam will be open 51 hours.

The duration of the test might mean that students can leave and come back (or even take the test at home). If that's the case and students are looking up the answers from the test bank (as opposed to memorizing them all ahead of time), then I'd definitely lean more towards it being cheating.

That's the impression I got; they were bringing the answers to the lab.

My guess for what that meant was different: that you could go to the test room any time in that window, but his emphasis "if you have to give birth, you're going to give birth in the exam room" suggested that once you entered, you were under some observational time control and limits on reference materials for the duration of the test. That is, it was not a 'take-home' test.

The bimodal distribution he showed did not have the massively sharp mode, or bulge at perfection, that might be expected if people were looking at the answer key while answering. Instead, it appeared to be two normal distributions, with different averages, superimposed. That suggests to me imperfect pre-test memorization of a larger answer pool, some of which was forgotten during a monitored in-room test.

At some point, knowing all the answers to all potential questions is knowing the material

How do you explain the bimodal distribution?

Previous submissions of the same story from various sources. They all have some discussion:



http://news.ycombinator.com/item?id=1922243 <- This has the most comments


What the professor knows:

- Some students had an advance copy of the test

- The grade distribution indicates cheating

What the professor doesn't know:

- Who cheated

Unless the university has access to a students network traffic proving they had access to the test, there's no way to be sure who cheated. The fact that the professor trudges through threats and vagaries for a full 15 minutes only seems to underscore this.

On the contrary - there's a few things they can do. They could examine the difference in results between the two tests at the individual-student level, for example. Or, using the set of students who admit to their cheating as a training set, do a question-level analysis.

Doesn't prove anything. Sometimes you don't get enough sleep and do poorly on a test. Sometimes you just have a great day. Using statistics as though they are hard facts and not merely suggestions of likelihood is a terrible idea when there is a question of guilt or innocence.

I have in the past had wildly fluctuating grades. Don't believe everything your powerpoint-prettied software stats tell you.

Does it 100% prove it? No. But what he can easily do is call up the top 200 most suspected students, get them to sit down in an office with nothing but a calculator and a pen and give them a very small subset of the original questions with the numbers changed. 20 people might be able to get them right, but a good 50 people arn't going to know where to start for any of the questions. Then all of a sudden it is "oh shit" time. If I were one of the "cheating" students I would come forward too.

This actually happened when I was studying engineering at Waterloo. The course was calculus 3 and the prof, who normally taught math majors, didn't know that there was a university commissioned exam bank with previous exams for courses. Course coverage was sporadic for all but final exams, so we normally didn't check it, but the previous midterm was actually there. One of us found it 24 hours before the midterm, so half of us got it and half of us didn't. The prof had reused the hardest question. Long story short, nobody got in trouble, but the prof made it so your top and bottom "midterm" (there were 5 of them before the final) could be optional dropped together or not at all.

Hey, at least he feels better now that he grandstanded and made himself feel like a big man catching so many bad little boys and girls.

So, at least where I went to school (Georgia Tech) it is well known and accepted that students have word of basically every question that's ever been asked for any given course. Professors also commonly post previous exams as study guides for courses.

Is this not common elsewhere?

in all the universities I've seen in italy you always have access to the previous written exam tests for preparation. For the oral part, when teachers have repetitive behavior, I've often see people collect datasets and use them for studying.

But the case seem different: the teacher in question actually took the tests from a given set and this set was known in advance. This is silly of the teacher, not of the students.

Dartmouth College and Stanford Business School classes did. We often had old tests to study from. Professors need to work harder and think up new questions each year!

Many classes I've taken know this yet still don't bother to change the questions. It actually skews the playing field towards those that have a lot of connections at the university as their more likely to have access to more past exams as many lecturers deliberately avoid placing them online so they can be lazy.

It was the same in my university and every other university I know of. Previous exam questions are widely available for all popular courses.

It would be foolish to think otherwise. What's to stop a student to write down questions after taking an exam and pass on to his juniors? Since this cannot be prevented, the faculty must assume that all students have all previous questions as part of their study material.

Sometimes a professor knowingly reuses his old questions. In that case, the students should warn him: not for the professor, but for their own good. Because otherwise, they will be evaluated on less questions (since almost all students will answer old questions correctly whether they really know the subject or not).

The students made only one mistake here, and it was taking that course from this particular professor.

Same at the University of Michigan, where all previous exams are available, and tests are composed anew each year by the GSIs and professors (usually more the GSIs).

It's exactly the same at Leiden University.

You have to think that if the professor really could identify the culprits he'd be limiting the retakes to them.

Maybe the real test here is for the students to realize that there is no "forensic analysis" in the world which could identify a cheater with 100% confidence except for the confession he is trying to bully out of them.

Of course, the test of confession doesn't have 100% confidence either. See for example the Innocence Project's page on this:


Let's say you are a student who was pretty sure that no conclusive evidence existed which proved that you had cheated. The optimal strategy might have been to, in writing, state that (1) you had not cheated but (2) had no way to prove your innocence. You cite your concern that, if you do not confess, you could end up with a failing grade or worse. So, as a practical matter, you have decided to falsely claim that you had cheated. After all, the only penalty (other than your professor never speaking to you again) is wasting four hours of your time in an ethics course.

Note that I did not say above whether or not you had actually cheated. Sadly, this fact is irrelevant with regard to strategy!

Yeah if the cheating students took game theory courses as well, they would know that the best action would be to remain silent. Stupid students!

The solution, of course, is to have open-book, open-notes tests. Let the students bring any notes, books, etc.; anything but a communication device. The questions need to be novel and challenging enough so that the students who understand the material can walk out in no time; the students who don't, can sit around flipping through their notes.

Of course, this approach requires the _professor_ to do a lot more work. (The few times I taught, I used this approach and always got rave or begrudging reviews).

So really, I have no sympathy for this professor if he adopted the "security through obscurity" approach (as in, the problem set wouldn't be accessible to students). I don't blame the students for doing what they did; in real life, don't we expect employees to use whatever resources they can to solve problems?

Exactly. The best professor I ever had did exactly this and he was from India and dressed like a cowboy (not important but awesome). He posted a few previous semester's tests online. And he allowed us to bring whatever assignments, reference manuals, etc. (except for computers) into every test, but wrote a brand new test. I think this sort of thinking came about because he was just the kind of teacher that really cared that his students wanted to learn and it showed in the lab assignments and when he was actually giving lecture. This is when you know what learning is really about and you stop worrying about grades.

600 students in that course, that's one hell of a challenge.

I might have missed something in the video, but if I were an innocent student, the benefit for me in falsely claiming I cheated far outweighs the risk in defending my innocence.

The choices as I see them are these, whether you're innocent or not: 1) say that you cheated, and you get to retake the test as though you never took it the first time -- you don't even fail the test! -- but you never get to ask this professor of a lecture with 600 students for a favor. 2) don't admit that you cheated, get caught in some dragnet based on pretty flawed statistical reasoning (or better yet, a witch-hunt), and "not graduate." 3) Best case scenario: You say nothing, don't get accused of anything, and you get the undying loyalty of the professor, though that loyalty fails at the first try, because it doesn't extend to you getting out of a test you by definition shouldn't have to take in the first place.

I'm a bit stunned that only 200 students "confessed."

An additional penalty for confessing was having to take a 4 hour ethics course.

I don't think it is really possible to keep a question bank secret. Some students tend to follow up with those who had taken the course last time, at least in my university. So if the question bank is voluminous enough, why not just make it open ?

Whats the worst that can happen, people might go through it and learn all the solutions. Well, let them, that's the purpose of the course anyways. But the question bank cant so small that it does not explore the full diversity of problems. And no one is claiming that all questions will be from the question-bank, throw in a few off question-bank odd-balls each year.

But how could they analyze the submissions to figure out (even approximately) who cheated who did not ? Apart from trawling their email and phone calls and wire taps that is....:-) I suspect part of the "forensics" was a bluff.

I can only guess that there are a few problems in the set that historically have a low probability of being solved correctly. So whoever solved those can be marked suspicious. But a test will have only a few of those.

But it sure sucks to be in a course where the instructor is unaware of the problem that QB is available and you are unwilling to look up the QB. Particularly where the QB was particularly designed for the top percentile.

> I suspect part of the "forensics" was a bluff.

I agree. It sounds an awful lot like a bluff.

While in college I worked as a teaching assistant, on a few occasions me and my staff identified cheaters.

No one ever got caught by getting the right answer. Cheaters got caught when they had mistakes in common.

Thanks - didn't see that

Your job as a teacher or as a presenter is to extend the available materials, and to provide me with insights that I might not gain from Googling existing materials.

Not to prevent me from accessing the available materials.

Not to control access to information.

If what I am learning from your teachings and from your tests and from other students can be entirely replaced by Googling through test banks, then you're not helping me advance.

If a presenter is reading off the slides?

If you're not utilizing what is available, whether Google or Khan Academy or iTunes classes or otherwise, you're not helping me make connections. To think. To research.

We see similar transitions arising in many human pursuits. In journalism. Booking travel. Financial markets. Programming. Music. And education. And in an earlier era of teaching, simply bringing calculators to a test.

Don't make me memorize. Make me think. Make me research.

It appears the professor has unwittingly also proved his teaching approach has failed.

"Your job as a teacher or as a presenter is to extend the available materials"

I'm puzzled by this. Let's say you teach basic physics or algebra... how are you supposed to "extend" the material, particularly testing material?

I always thought the benefits of having a teacher were: 1. Human contact 2. Ability to answer arbitrary questions in an instant 3. Ability to adapt lectures to the audience 4. Students in the presence of a room full of other people trying to learn the same thing at the same time

Those would all be great benefits even if the tests were all the same, administered in a standardized way, nationwide, by third-party proctors with third-party graders.

That's not to say that there's anything wrong with independent study, online courses, or ad-hoc groups of students learning together.

I just take issue with the idea that a teacher, in order to do their job, must also compose novel tests every year as though the new tests would somehow be better than all the other tests used over the years. If teaching honest students, it just doesn't sound like an efficient use of teaching resources to re-invent the wheel each time.

And there are objective benefits to using the same or similar tests from year to year. One is that you can see if your class is improving or lagging in specific areas compared with previous classes. That could help you hone your teaching over the years. Wow, I tried playing this game to illustrate economics, and these students scored way higher on the arbitrage questions than the previous 5 years! Or: "gee, I thought that group project might be good, but the test scores dropped this year".

Thinking like the instructor/presenter/seller quite clearly, though also remember to think like the student/purchaser, too.

You're clearly familiar with running the process line and incremental improvements for yourself and optimizing your work, but are you equally comfortable being the widget that's being processed within the assembly line, and whether the widget is getting the best value?

My trip down that educational assembly line was seriously and mind-numbingly unpleasant, and I can only imagine what it's like with all of the current standardized-tests model. Looking back, what we were taught and what we learned for those tests was sufficiently ridiculous and, well, wasteful. We didn't learn that most of what we learned would be outmoded, that the tools we were taught would be gone, and that memorization was far less practical than learning how to research.

As a presenter, I don't want to repeat that for the folks I am teaching. Though thankfully, I don't have to teach to standardized tests.

As an instructor, you're selling a service. Are your students buying?

"are you equally comfortable being the widget that's being processed within the assembly line, and whether the widget is getting the best value?"

A valid point. There are many ways of learning though, and if you want instruction and materials personalized to you, those are available -- albeit at a much higher cost. And there are other, self-directed methods of learning that are a much lower cost than either method (e.g., going to a library, doing research online, etc.). [Aside: who pays the cost is a separate issue, but someone must pay it.]

Given that society is constrained by scarce resources, I think that re-using tests is a perfectly reasonable allocation of resources for many teaching situations. Other materials are re-used regularly, such as textbooks, and there's nothing personal about that. Would you say that using the same textbook as someone else turns you into a "widget"?

It's unfortunate that your educational experience was so unpleasant. My K-12 experience seemed quite wasteful as well. But I think that has more to do with incompetence and laziness. Doing more personalized teaching requires more teachers, which means they will have an even harder time attracting enough quality talent, and an even harder time firing bad teachers. That doesn't sound like a net win on quality to me, even if it is more personalized.

Scaring shit out of you since 1981.

While it is generally true that good students should not cheat, but using questions from standard question bank was somewhat asking for it :)

Nice and simple trick with distribution and disturbances, though.

This is definitely cheating, but there's an important lesson for the professor: if you care about cheating, don't be lazy. Write your own exam questions and change them often.

You can tell that this is the most exciting event in this professor's life in the past 20 years. Maybe he should try varying his material.

The students actually were asked to confess if they had seen the sample test before the example or not. They weren't confessing to actual cheating.

This guy seems like a crappy prof to me. He essentially got caught taking the lazy way out and is now acting surprised and trying to blame the students.

Outside of the United States, there are test standards called the GC(S)E "A" and "O" levels which are roughly equivalent to entrance exams for college/senior high respectively. Because these exams have been going on for DECADES, the examining body has basically given up on guarding these questions i.e. they are regarded to be in the "public domain". Enterprising publishers have called these collections of questions the "10 year series", which are exam questions from the previous decade. There is not a single person in this part of the world who does not own a copy when preparing for those exams.

A close relative teaches in a continuing-ed masters program. The first two or three times she taught the class, the grades on the midterm were OK, but reasonably distributed. This fall, they were uniformly excellent. She concluded that the students had copies of her exams from previous semesters, and rewrote the final.

As far as I know, it never occurred to her to tell the students off. Of course, these are twenty-somethings and probably a lot less susceptible to brow-beating.

I use to have a professor that actively encouraged us to review old tests, question banks, friends, anything we could get our hands on. Hell his tests were even open book/notes.

The tests were genuinely difficult. You could pass by looking at the material because some of the questions were just lecture examples with numbers changed. But to really ace the test you needed understanding of the material.

Im sorry but this is the education system FAILING its students. 1. fear mongering by the prof " FORENSICE ANALYSIS" and "LEGAL ACTION" 2. the SAME test for the last FIVE years? 3. some crap sob story about "what were the last 20 years about" ... how about you being a lazy ass professor?

I'm a 5th year PhD student who is teaching a large (80 student) section of a course, this is the 4th course I've taught. I've also taken plenty of exams as a student, and they are still fresh in mind.

I would want to know more information before I decided the students were cheating or not. The instructor refereed to an "exam room", and gave an hour range that the new exam could be taken. So the students are not all taking the exam at the same time, this makes it seem possible that the exam is online. If the exam is online, and the students can take it at home vs take it in a proctored room, that would change what would be cheating. If it were online at home (I don't think so from the video) then reviewing the test bank while taking the exam would be cheating. If not, then having seen a question before the exam may or may not be cheating, depending on HOW you saw the question.

If you did not acquire questions in an unethical way, then it's not cheating, it's just studying. As an instructor, I will sometimes put problems from the book onto my exam. If the students worked the problems before because they were studying hard, then good for them! I want my students to study, because it will help them learn. I also provide a sample exam with previous exam questions on it; I write most of my own questions and it's important for students to get used to my style. As a student, I had to take a written exam for my PhD. When I was studying for the exam I asked Professors for help, one of my Professors gave me some of his questions. I worked out every single question. He also submitted one of his existing questions to the exam and I recognized it when I was taking the exam. Cheating? No. I just got lucky (and worked my ass off).

If test questions are acquired by malicious means, or knowing that they are going to be on the exam, or are the test bank that is going to be used to make the exam. Then it is cheating. So if students knew that the questions came from a test bank, and downloaded the test bank (I'm sure it's on the web somewhere) to gain an advantage they cheated.

Finally, as an instructor. Writing a decent exam is surprisingly hard. My goal with an exam is two-fold, figure out how well the class as a whole is doing, and separate the students into their grade groups. The ideal exam has some problems that even the D students can answer (to separate them from the F's) and some problems (usually just 1 problem) that are a stretch for the A students. And a mix of medium problems for everyone. If you have too many easy problems, the grades will creep up and you won't separate students. If you have too many hard problems, the grades will creep down and you won't separate students. Writing an exam from scratch is very time consuming. I use my private test bank, and try to add 1 or 2 new questions to the bank when I'm writing each exam. I can understand (but don't agree with) an instructor pulling entirely from an existing bank to write an exam.

"Writing a decent exam is surprisingly hard."

I hope I don't come off as flippant, but you're shooting for a PhD, the most advanced degree you can hold (if I'm not mistaken); isn't "surprisingly hard" kind of the name of the game? I'm sure if you ask students, many of them would say taking the test is "surprisingly hard," are shortcuts justified for them too? I'm sure a building contractor will tell you keeping track of and in compliance with environmental and safety regulations is hard, but we expect them to do it nonetheless, because that's his/her job!

Ultimately, whichever method allows the instructor to most effectively perform his or her job is best, and maybe that's question banks. Cases like this one are notable because they call into question the stance that using banks is as effective/more efficient.

Good luck on your degree!

I'm not interpreting your comment as flippant. :)

In terms of shortcuts, that would depend on what they were. Some are fine, others are not. E.g. 'borrowing' answers from other students on homework is a shortcut, but it's okay if the student understands the material in the end; cheating on an exam is not an okay shortcut.

"Surprisingly hard" is the name of the game. I mentioned that writing exams is hard to motivate why an instructor would use a test bank. At a research school (I'm at a research focused school), being an instructor is only a small part of a professors (or grad students) job. Using a test bank (from books/publishers or private ones) is considered to be fine, as it lets them focus more time on the things they "should" be doing. Many things that are considered okay in this context are abhorred in others, e.g. having grad students be primary instructors is okay here but would be taboo at a teaching focused school. Of course, most teaching focused schools don't have big grad programs.

Incidentally, I'm on track to graduate this year. I'm sending out academic job applications and I find myself more drawn to teaching schools than I thought I'd be.

It's hard, not because it is hard to think up questions, but because it is hard to anticipate their level of difficulty. This usually requires some data to measure. Teachers would rather spend effort measuring the students than the questions.

At my university usually all tests are published by the institutes themself on the iternet. They even advice you to train with the old exams. Some of them are also open book. But every exam is individual and so different (not only numbers changed) that you really have to train all the stuff to get a positive mark. Relying on "secret" question caches or buying questions from a third party is not very smart, lazy and really makes no sense to me. They did´nt cracked the system, they only used it for their belongings.

Students repeat courses, audit courses. Students can be exposed to these canned test questions in this way. Universities push the general learning experience in selling their education product. Those who want to make the student the commodity and control how they learn for better quality control strike me as dyed in the wool bureaucrats.

What a petty man.

"The days of finding a new way to cheat the system are over."

He's full of crap! He doesn't do any attempt at proving at all. He merely keeps threatening and intimidating, and the only thing he knows is that the numbers are suspicious.

This disgusts me, but I totally believe it, as a college student seeing these kinds of numbers do not surprise me at all.

Where I go to school though, the test is given at one hour on one day. The whole you have 52 hours to take the test thing. It seems like whoever takes it first could still help others study.

After being so upset with his cheating class, why does the professor offer a large time period to re-take the test? It seems like he is baiting the students to cheat again. Can't he set it during a normal class period where everyone takes it at once?

For most courses the exams don't stray far from what's already been asked before. Competition between universities has made this problem a lot worse. Students choose courses with high pass rates and favorable grade ratios.

The prof's home page states: "Important Note: I have chosen not to participate in any social networking environments." http://www.bus.ucf.edu/rquinn/

The entire education system is essentially one big game, from the obscure admissions process to professors sticking to predetermined grading distributions; and these students are simply playing along.

It was probably more work to memorize the test bank than to study the material as normal... It's ironic that those who memorized the test bank probably know the material best.

Here's the video of a part of the first lecture in which he claims he writes the test questions:


Based on that, I think a reasonable student would conclude that even if a publisher's test bank is not supposed to be accessible to students, using that test bank would not constitute cheating. Since the prof wasn't forthright in stating that he would use the publisher's test bank, he has no right to complain that students used it to study.

Those who cheated because they did not know the material will not do as well on the makeup. That is one way of finding out who cheated.

By your logic, those who did well on the original exam but could not do as well on the makeup because they happened to have a bad mood/health/etc. will also be qualified as cheaters.

How does that make sense?

I just wish I could plusvote this one twice.

"The consequences will never be the same!" ;)


can you please explain that for future use?

Referencing past submissions about the same topic, whether they are exactly the same or merely similar is very useful, especially if those past submissions contain discussions.

You should always link to those past submissions and remain otherwise neutral (or positive if you like). It is not and cannot be the submitters duty to closely track Hacker News for all stories that have been submitted in the past [0]. Duplicates are inevitable, just writing “dupe” helps no one. Be constructive!

[0] I’m not entirely sure whether the submitter should check the front page before submitting. Since a bookmarklet is officially endorsed and prominently linked I would rather think that checking the front page is no requirement. You should maybe only be careful and check the front page or the new page when you want to submit a story about an event that you know will be a hot topic on Hacker News (say, a Google press conference).

As a new member in Hacker News I have thought of this problem a bit. I would like to know the opinion of the community. There are some pearls on the internet that even though can be old and maybe posted before(some months or years ago) they can be useful, interesting and even rekindle discussions where new ideas can be introduced. At the same time posting something that was discussed one two days ago and attracted attention(as you have pointed- I am not talking about the specific topic but in general) should be maybe linked to be fair with the original uploaders.

And I agree that it is good practice at least to check at least the first page of Hacker News or the "news" section to avoid obvious duplicates .

Actually, duplicate submissions for the exact same URL are counted as up votes for the first submission. So using the bookmarklet poses no problem. Using different URLs (thoughtcatalog vs youtube) for the same story causes difficulty, though.

Who cares? This is the first time I've seen it.

All 4 current comments on this story are completely worthless.

I found the link to the past discussion useful and the gratitude expressed for said link uplifting. :)
