Interactive quiz for lectures

[danm0nster]

It would be nice to have a special kind of quiz, that can be used in a live situation, such as a lecture, and where the results would be collected, and could be presented by the lecturer. I envisage something akin to Mentimeter, Poll Everywhere, Swipe, Questup. etc. Perhaps there is an open source JS tool that can be embedded?

Definitely. Here I think a very simple server needs to be set up. Correct me if I am wrong, but I do not see how the instructor can handle quizzes in a classroom situation without going through a dedicated server i.e., he needs to start and stop them and display graphs of the answers. Also, the students need to communicate with a server through their smartphones. Then again, perhaps we could be creative and bypass the server option.

A "serveless" option could be embedding a hosted poll solution like this one https://strawpoll.com/en/help/how-to-embed-poll/

This could be a life server not wanting to code and host. Thanks.

Unfortunately I have been unable to iframe https://polleverywhere.com and https://menti.com (AU subscribes to the latter). These two polling system support LaTeX. It is not clear to me if StrawPoll supports mathematical notation in terms of LaTeX. Would be great if this was the case.

An alternative to poll systems that don't support latex is making your own frontend with a poll system that has an API for answering questions. Then you could render questions however you want. I might suggest socrative.com because I remember a friend making a terminal app for answering quizzes (https://github.com/Hense94/socrative-cli) but I think he just reverse engineered their internal API. Doing the same might very well work for you, but it would be nice to have a service that willingly publishes their API.

It seems that https://mentimeter.com can be embedded (see https://help.mentimeter.com/en/articles/410896-embed-your-presentation-on-a-webpage):

The truly sad state of affairs is that LaTeX only works in the question and not in the answers. This is a mystery to me. Surely https://polleverywhere.com must be better suited for science. Just need the API.

It seems that mentimeter can be embedded rather easily in QaDiL by simply defining the macros

\newcommand{\mentimeter}[1]{<div style='position: relative; padding-bottom: 56.25\%; padding-top: 35px; height: 0; overflow: hidden;'><iframe sandbox='allow-scripts allow-same-origin allow-presentation' allowfullscreen='true' allowtransparency='true' frameborder='0' height='315' src='https://www.mentimeter.com/embed/#1' style='position: absolute; top: 0; left: 0; width: 100\%; height: 100\%;' width='420'></iframe></div>}

\newcommand{\menti}[1]{\begin{hideinbutton}{Mentimeter}
\mentimeter{#1}
\end{hideinbutton}
}

Then the button can be opened in the lecture and live voting can be presented on the web page. The input for \menti is simply the id for the quiz, like

\menti{7f433fb3f31fd6da8e9d9fd796d4db94/09dd8d3fe096}

This is very useful, @nielsthl ! Thanks!

It seems Poll Everywhere allows for mathematics in the answers as well (see here), and you can embed with <iframe> similarly to Mentimeter (see here). I don't have a Poll Everywhere account, so I haven't tried it.
