Part of my job is creating learning materials (such as example questions) mostly for first year undergraduate students in Engineering, and i find it difficult to believe that there does are no free online resources for example questions based on topics. It is crazy to think that every time an institute wants example questions they have to make them from scratch instead of having an online place for people to post to and look at when needed.

I know that MIT open course ware now has some assignment materials, however you cant search by topic (ex: search for “eigenvalues” to get a list of problems to test eigenvalue knowledge) as well as its only MIT and there aren’t many assignments per topic (and some require you to have the book which defeats the purpose).

Is there anything similar out there I could use to get examples from and even put my own examples out there for others to use?

(Keep in mind it has to be official, I know there are some places where students can upload materials from their courses but those are not always gotten with permission)

I’ve recently joined a new lab; an experimental physics group of ~30 people, consisting of postdocs and PhDs and a few PI’s. All of these people are using/sharing/rotating between a number of setups, machines, fabrication techniques, and so on. From what I’ve gathered the way information about these things is exchanged is mostly horizontal; the new PhDs learn from those who have already been there for a while, and they themselves learned from those who have already been gone for a few years. In my opinion, this way of learning leads to a lot of lost expertise over the years (PhD cycles), or at the very least to a lot of inefficient re-discovering of what was already known at some point.

I therefore thought it would be a good idea (not my own of course, it was already done like this in my previous group and I assume it to be common practice in many places) to start a wiki-type environment for our lab. A place to collect knowledge of the different setups (manuals, wiring diagrams, tips and tricks when encountering issues), fabrication recipes, maybe even administrative steps to take when a student enters or leaves the lab. This is not an exhaustive list by any means of course.

My question was if anyone here has any experience with this, in terms of how to set something up and what good practices would be. It definitely does not have to be free if that means better privacy and features.

This question Good practices with lab wikis? touches on it a little, but that’s all I could find. That’s probably also because the question is perhaps a little offtopic; setting up a wiki is perhaps not the most academia related question one could come up with, but I do feel like because it is only to be used in the academic setting some of you might have experience and insight I wouldn’t get somewhere else. So if anyone has any experience with this, or any tips on how to get started, that’d be much appreciated.

I am researching how reliable, trustworthy, and bias certain free sources are. One such source I have not had a chance to use is Encyclopedia.com.

https://www.encyclopedia.com/

If you have used it, can you share what it is like? I will use it myself but I can’t check everything. If you have used this site and/or noticed any bias or untrustworthy content, could you share your experience?

Thanks, JS

The question (Is studying past exams I found online cheating?) was sort of relevant but did not answer my question, so please do not mark this question as a duplicate:

Onto my dilemma:

I recently had a raw score 20 points higher than my classmates and was suspected of cheating. I scored almost perfect while others only got around 60-75. I actually found the test beforehand (coincidentally) because my teacher passes back old tests and quizzes (and his sources are obvious). I sought online materials because the textbook and the practice problems are utterly inadequate for relatively difficult exams. I know it gives me an advantage, but couldn’t everyone just do what I did? Don’t I have the right to study things that are openly accessible on the web and use that to my advantage? It’s not like I hacked a school server to access materials.. I literally just found it by using some google search ‘hacks’ like verbatim, quotes, filetype, etc. I ended up not getting a score for that test, but did the teacher really have to do that? I didn’t even copy the test word-for-word. I knew how to do most of it and just used it to make sure that I knew what I was doing. I am currently under a lot of backlash due to this incident and am trying to justify my standing. What are your thoughts and what prevents me from using those sources?

Clarification: it was not even the teacher’s own test.

On my book there is the following reference:

Buckles, R. G., 1966, Analysis of gas exchange in a membrane oxygenator, Thesis, Massachusetts Institute of Technology, Cambridge

I tried to find it online:

https://dspace.mit.edu/handle/1721.1/7582/browse?rpp=20&order=ASC&sort_by=1&etal=-1&type=title&starts_with=A

http://library.mit.edu/F/XQ39BH41Q8C9V3XHXK5XA7EMFR5V5R9QDNSCKDFTNN4JNSS2SF-02835?func=find-b&find_code=WRD&request=Analysis+of+gas+exchange+in+a+membrane+oxygenator )

but without success.
Can you show me where I can find it please?

Thank you so much for your time.

In an upcoming publication, I need to link to the data I used for the publication so that others can see/use the data as well — both for reviewing the given work and also for intended use in the future. However, my institution has not offered any hosting solutions and I have not (yet) found any acceptable external solutions which absolve me of financial and legal responsibility for maintaining the data and the hosting infrastructure. I will not be at the given institution for very much longer, so e.g. putting it on my personal site at the institution is not a solution. The primary data in question is about 12GB in size, so it needs to be a proper “repository” for the data rather than just e.g. an attachment distributed with the publication itself.

Nevertheless, I need to at least have a stable link to some place where the data can be located; The stability of the actual location is not as important as the stability of the link itself. How/where can I procure a permanent URL to link to research data in a publication which does not cost me anything as an individual?

A full graduate level course is publicly uploaded as a series of videos on Youtube. Within the housekeeping section at the beginning of the course, the professor provides an email address as a means to contact him with questions. No attempt is made to obscure this email address when the video is later uploaded.

Obviously, the professor’s primary intent was for members of the class to have a way of contact, but would it be within the bounds of etiquette for a Youtube viewer following the course to email a question about the course material? Suppose the question is of a sort that would not be well suited to ask in a Youtube comment. Perhaps the question is long and includes images for clarification, but let’s assume that the answer would not be proportionally long, that the professor could answer it fairly quickly and easily. Would it be okay for a Youtube viewer not enrolled in the course (perhaps after the course had ended) to send such a question to the professor, maybe with the qualification, “Please do not feel compelled to take time out of your busy schedule to answer this, but I was watching your lectures on YT and was wondering…”?

I’m trying to create an online survey where the participant hears a series of sound files and rates each of them on a likert scale.

The sound files each depend on two variables and there is one file for each combination:
e.g. If the two variable can take the values [A, B, C] and [1, 2, 3] respectively then there would be 9 possible sound files:
A1, A2, A3, B1, B2, B3, C1, C2, C3.

I want each participant to hear an example of each variable exactly once.
e.g.
A2, C3, B1 and B2, A1, C3 are both valid series of sounds (no letters or numbers are repeated)
but
C1, C2, A3 and A3, C1, B3 are not valid series (a letter or number has been repeated).

[In my case I have 10 values of each random variable, 100 sound files].

I’ve tried Qualtrics and REDCap but cannot see how to do this sort of randomization.
Is there an online survey creation tool that supports this functionality?
or failing that, can anyone explain how to to this in Qualtics/REDCap?

[Apologies if this is not the correct place for this question, feel free to move it somewhere more appropriate]
