Today we (professors + teaching assistants) proctored a midterm exam for a class of about 80 students. There was undoubtedly a “hardest” question on the exam, since nearly the entire classroom of students asked us how to proceed with that question. To be fair, we didn’t give any hints, but it was clear that one had to use a definition to be able to proceed.

When we collected the exams, all of the exam booklets had that question unanswered — except for one student’s exam. And this was the only student who asked to go to the bathroom. I gave him permission to go, but I did not ask for his phone, which I now highly regret.

What can we do in this situation, in which I strongly suspect that this student went to the bathroom to look up a definition on his phone, so that he could answer the question correctly?

We still have to look at every exam to be sure that only one student got it right (the bathroom student), but if this were indeed the case, do we have any power to accuse him of cheating, or, have we missed our chance by not asking for him to leave his phone in the room?

I feel a big injustice will have been done to the rest of the honest students, if we let this one slide …

Last year I completed an exam at University and a friend is doing the same exam/class this year.
Would it be cheating if I gave her my revision notes of the semester (written before I did the exam)? They don’t have any exam-related answers, just summarized lecture notes.
I read that it is cheating if a student has an unfair advantage over other students.
I don’t want to get her or myself in trouble.

Thank you.

I have an experiment where I am having participants rate the readability of 10 different texts. I have 37 participants and I would like them to rate the readability for 6 texts each so that each text will be rated by at least 20 different people. However, I’m concerned about order effects in the presentation of the texts so I would like to use a Latin square design. Is there any way that I can modify the Latin square design so that I could present 6 texts to each participant rather than all ten?

I’m writing the introduction for a research proposal and am trying to express that our approach is “experimental” in the sense that it uses more exploratory and alternative methods rather than that it uses a controlled experiment.

Is the phrase “experimental approach” appropriate in this context? If not, what are alternatives? (Words like “novel” and “exploratory” aren’t quite right.) Which way should that phrase be interpreted in general?

Someone I know (or maybe me) wants to audition to the instrumental music section of LaGuardia High School on tuba. Can anyone give an example of a piece of tuba music that would get a tuba player into Laguardia? (Of course this should be music playable by an 8th grader, so it would help to post a piece of music that actually got somebody accepted.)

Note: I could not find a fitting tag for this, and do not have enough reputation points to create a new one, so the the tag does not entirely match.

I have been following 7 journals at the same time for may be about 10 years now. 4 of them are relatively unpopular and publish may be about 50 papers per year,, so they are easy to follow, 1 has 100+ papers so it sometimes requires an effort to follow everything they publish but the other 2 are very popular and publish biweekly full volumes with dozens of papers, so it is a pain to follow them and I need to look at their webpages to see what is new almost every day. However, I work in such a field that I always need to look for papers outside of my field and hve to browse to many journals irregularly to find possibly interesting information. That means I browse through dozens of journals irregularly and have to look through literally thousands of papers. And, oh God, it takes its toll. But the REAL problem is my requirements only get broader with time, so I now can’t just keep on. I think there are really too many journals and too many papers to browse through and I can’t even manage to read through all the titles of all the papers that could potentially interest me, let alone read the abstracts.

This is why I would like to try find someone who has similar problems and ask him/her how does s/he manage to solve, e.g. what does it take to browse the maximum number of journals possible as far as search optimization, number of journals covered and time are concerned? Is it possible to cover a wide field to follow everything it happens in it and be aware of the new papers published in dozens of journals or this is simply impossible? I want to know how far can I get and how much time would the effort consume, so, if you could share with me your experience I would be very thankful.

Thank you very much!

I am a Masters student in maths in Toronto and changed supervisors one year into my Masters program. My new supervisor was expecting me to to a PhD with him, but within two months of switching to him, I mentioned to him that I would not be pursuing a PhD. I mentioned to him that I haven’t decided what to do after my Masters, as I would like to work hard on my Masters thesis and write a good thesis.

Even though I said this, I am spending half my time learning data science because I would like to transition to data science after my Masters. The fact that I have only been putting in a minimal amount of effort to my thesis is reflected in the amount of work I complete every week before my meeting with him.

I have recently decided to fly to Chicago for a networking event in data science, which means that I will not be on campus for one working day of the week and also I will miss my supervisor’s group meeting. I have already mentioned this to the course instructor for which I am a TA this term and he’s switched my office hours for next week.

Now, the course instructor and my supervisor are in the same research group, and I am afraid to ask my supervisor for a leave for one day because I have been putting in a minimal amount of effort for my Masters thesis.

Should I ask my supervisor for a one-day leave, or should I not tell him and miss the group meeting and just return to work the next day?

I am a mature student. I work full time and I can’t access a tutor face to face. I have to use online solutions. I have a Wacom tablet that I use to draw Math content and I screenshare over Skype. I am looking for a whiteboard/screen drawing/screen sharing software that:

  • responds well to handwriting with a Wacom tablet
  • allows real time annotations to be made by me and my tutor
  • must work on both Windows and Mac

I bought Office 365 (Skype for Business). I would have liked to use the whiteboard sharing facility that Skype for Business comes with except, even though I already paid for it, the whiteboard sharing facility has never worked. Installing Skype for Business was not straight forward. Even after Microsoft staff assisted me, the installed software does not allow access to the feature that I bought it for initially. I will ask for a refund.
I don’t mind paying for such software. Just needs to work well. I apologize if my post seems a bit vague. It is only because English is not my first language.

I’m looking for post-doc position, and applied to a position. Here’s brief flow of email converstaion.

Possible PI: Well, it looks like your research interest and experience matches well with mine, let’s have a interview.

Me: Thank you. When can we have a discussion?

Possible PI: (No response)

3 days later

Me: Hello? Do we have interview?

Possible PI: (No response)

more 3 days later

Me: Hello? Can I have interview with you?

Possible PI: (No response)

I don’t know what is going on his side, but I never wrote something rude or stupid. Can I regard this sign as refusal? Or do I need to email him again? Or can I call to his office phone number?

I don’t think his reaction – no response – is polite at all, at least…
