671. External tools to make up for shortcomings in Canvas LMS

Not a fan of Canvas LMS at all. There are too many things missing, too many things that don't work well, and ultimately I feel it does not work well for me as a teacher.

In contrast, I felt that on the whole Moodle offered the tools that I needed: a well-functioning quiz tool, a good forum, and  good tools for making exams.

The forum in canvas is confusing to the students, and is hard to organize. 

The quiz function is very limited in scope, and does not offered a good overview of responses. From what I understand you can de-anonymize reponses as well. It's not a good tool for course evaluations for these reasons. It also doesn't work well for getting responses from discussions as part of a flipped classroom.

Also, you can't attach more than one document to a question when answering. Even worse, attached documents that are uploaded by students end up in THEIR accounts, so that they can e.g. delete them after they've taken an exam. Anything to do with exams/quizzes should be immutable.

I don't have a solution to that last issue, but here's what I've done with the rest:

Course evaluation: 

mentimeter.com. We have a license. The course evaluations look great and are easy to interpret.

Otherwise I'd use google forms.

Feedback during flipped classroom discussions: 

Google Forms. It works well, and gives an easy overview of responses in real time. If we didn't have mentimeter.com I'd use this for the course eval as well.

Forum:

ProBoards. I also looked att making a Google Group, but that worked about the same as the Canvas forum. ProBoards looks and works like a real forum, and you can let students self-register. You can also create custom names/URLs for your forum(s) -- mychemforums.proboards.com.

[Examination: For now we use moodle for this, although we've been told to phase this out. Instead we're going to be using Inspera, which at a glance if anything seems less suitable for chemistry exams than moodle. Time, and testing, will tell.]

670. Issues with the RSC latex template -- text shifted on debian buster

Using the RSC latex template -- last updated 2016 -- works fine on debian stretch. However, on debian buster the text is screwed up on all pages except for the first one: the header is way too big, and the text runs off the page at the bottom.

After having spent a lot of time looking at log files, comparing installed packages on different machines, and generally not making any progress, I finally found this:

https://tex.stackexchange.com/questions/495662/rsc-template-fancyhdr-doesnt-respond-well

which links to 

https://tex.stackexchange.com/questions/491859/what-has-changed-in-latex-that-means-the-rsc-template-no-longer-works#comment1242180_491859

Since links die occasionally I'll summarize it here (I DID NOT COME UP WITH THIS SOLUTION):

Fancyhdr has been updated between stretch and buster, and while the maintainers at Overleaf have fixed the RSC template and notified RSC of the changes necessary, the current (8/3/2021) version of the template is still faulty.

To fix you can either 

1) edit the .tex file template itself

a) Comment out 

\fancyhead[C]{\includegraphics[width=18.5cm]{head_foot/header_bar}}
\fancyhead[L]{\hspace{0cm}\vspace{1.5cm}\includegraphics[height=30pt]{head_foot/PCCP}}
\fancyhead[R]{\hspace{0cm}\vspace{1.7cm}\includegraphics[height=55pt]{head_foot/RSC_LOGO_CMYK}}

b) find vspace{3cm} after \twocolumn[..] and add

{\includegraphics[height=30pt]{head_foot/journal_name}\hfill%
 \raisebox{0pt}[0pt][0pt]{\includegraphics[height=55pt]{head_foot/RSC_LOGO_CMYK}}%
 \\[1ex]%
 \includegraphics[width=18.5cm]{head_foot/header_bar}}\par

right before it.

Then change \vspace{3cm} to \vspace{1em}

or 

2) add some extra .sty files to the folder with your .tex file. Those files are:
balancy.sty, caption.sty, caption3.sty, fancyhdr.sty, mchem.sty and secsty.sty

They can be had from https://github.com/bardsoftware/template-RSC/tree/master/Paper

669. Checking how many students attended a zoom lecture, afterwards

 This is an easy one, but you need to know that 1) the option is there and 2) where to look.

Go to the web-interface to zoom at your institution, and click on log in:

Now that you're in, go to to Reports:

Then go to Usage:

Now, search for the time period that you're interested in:

And click on the number of attendees. Note that if someone gets disconnected, and then reconnect, they're counted twice, so this is not the value you want to use:

Instead, make sure to click "Show unique users" to see how many students actually attended. You can also export it as a csv file which is probably a good idea since you'll need to count by hand otherwise:

That's it.
