Prof Gives Lecture to Prove He Knows Students Cheated; Over 200 Students Confess

#12But 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.) See: http://www.tech…
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.

#13The 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.

#14Scaring 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.

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).

#17So, 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.

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 .

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?

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?
