Re: Teams on Linux
The other school my children attend uses Google Classroom, and it was my children who first spotted that Google had added the "Meet" facility to the usual list of options before the teachers had noticed, and held online get-togethers from very early on in lockdown.
My main concern with Classroom is that while Google says they won't pass on the data, it's obvious that they do - I've had this argument here before, but I am not at all happy that when logged in to Google Classroom, YouTube "knows" it's a specific child using the computer and sets filters according to age data that should not be shared outside Classroom. In one instance this blocked a video from being watched which the children had been asked to watch as part of their lesson! Easily sorted by opening the link in Firefox Private mode, but that should not be necessary.
We found that Teams works ok - if rather slowly, but that's understandable when you look at the data it is pulling in from a vast range of addresses - with Firefox on OpenSuse (15.2) for all the functions we tried, except video calls which have to be made through the client software. I was slightly surprised to see a Linux version was actually available. We'd have been stuck if it weren't as we don't have a Windows machine in the house, and our only Mac is so out of date (and non-updatable) it is barely usable to browse anything more than the very simplest of websites.
The main problem with online education is that some schools just don't seem to have thought through what might work and what might not. I get the distinct impression that some of them were rather hoping that it would all go away and that come September with all the children back in school, everything would be back to normal, though perhaps with a few more children "off sick" than usual.
Of those that have thought it through, there's an interesting question about the long-term value of the additional equipment (webcams, laptops) and licences they have had to buy. If there's one thing I am certain about it is that at least 50% of the value of school is the social interaction, and you get significantly less of that as a passive viewer of an online ppt stack.
