Hi, With the Coronavirus pandemic, my school will close like all the others. We chose to work with Microsoft Teams. I know how to file Math exercises written with ConteXt and export to pdf format. Is it possible with ConteXt to create interactive Quizz?

You can create forms that work in Adobe Reader, but Radiobuttons are broken in ConTeXt, and if you want to add validation, then good luck getting JavaScript functions to work. radiobuttons are broken by design: initialization, default rendering, synchronization over pages (we have a parent child model for which support seem to differ per viewer/version) ... it's hard to support all

Is it possible with ConteXt to create interactive Quizz? it should be doable (in the past we've made those with choice, fill in etc questions) but one problem with pdf is that there has been introduced some restrictions, for instance one cannot save in the reader so one then need to run a server that picks up the filled in stuff and regenerates a pdf file ... no big deal but i must admit that i don't have that code (if at all) around in loadable module form

In google chrome this seems to work, apart the choice fields (the choice selected has the red frame but it has no mark inside): https://martin-thoma.com/images/2012/02/pdf-form.pdf -- luigi

Thank you, I will try to use your file. i'll add a mkiv variant to the distribution (a few minor tweaks)

there are some examples of form stuff in the test suite (widgets)

i'll send you a file from 2000 that does some mpc magic (including feedback and score calculations) but it's mkii (so you need to run pdftex). Maybe I should check it with mkiv too.

Could you please tell us where to find that file, even if it is only with mkii? (I need to prepare some material for my students, for the same reason as Fabrice…).

Where? On my machine, in various places. The problem with such things has always been that publishers are not really interested in it (or not ready, or whatever) so experiments end up as orphan files. Take for instance http://www.pragma-ade.com/itdemos/external/ex-files/ex-files.pdf We have all the examns from the mid 90's that way. That version doesn't have the selection part (choose examns and questions and generate remotely a set of examn files). Lack of interest in these matters made is drop all kind of support files for that. Other experiments involve testing based on pdf documents, and/or student progress reports using pdf files (basically forms but not that recognizable as such) where after a click the student got an updated document that (s)he could store and expand later on. Again, we have basically all the building blocks in context (the sql database as well as the service itself were controlled by luatex). Currently we're playing with yet another technology where a complete (already around for a while, free) math school method is available as pdf ad well as web but again, not something for publishers so hard to even break even (most of this, also tex related, stuff is kind of a bottomless drain of time and therefore money, so doing it is mostly hobyism). Anyway, I'll mail a few files (no upload yes, maybe later). I have no problem coming up with additional styles of code for remote learning and student support but it has to have some 'direction' and not be too random.
