Guys why camera?? Everyone has a laptop and/or PC. The investment e.g. a phone stand costs 20€. I get equipment provided (laptop, cables, phone), cordless mouse, 2 cables or an adjustable lamp I bought myself. Why? I easily save those 40€ on gas. L
Believe me, I manage IT with 5 colleagues in a large company. No, by far not everyone has a PC/laptop and if they do, you want to cry from nostalgia because they remind you of Windows 95 and older. Sure, the colleagues probably bought their special requests regarding mouse, keyboard, or lamp themselves for home office. But the basic equipment must be provided by the employer. Not least so that everything is on the same level regarding security and support. (Fun fact: setting up each person’s private monitor as a dual monitor via Teams borders on self-harm).
Now let's bring that down to teachers: every teacher has their own technical stuff set up to get Teams and co. running. Everything from Windows 7+ to Linux/Apple is included. Now the IT person responsible (a parent/teacher) of the school is supposed to coordinate this. You don't stand a chance of doing this even remotely satisfactorily. On top of that, we have many senior teachers. It is already a challenge to explain to them how to install software. So you need an incredibly long time to make them digitally capable of working. But you also can't expect them to do it themselves. Many are so behind that it totally overwhelms them. Google and a YouTube video don’t help here either.
The students are the smaller problem. For them, it simply boils down to lacking infrastructure.
About the "IT stupidity": years ago my mother-in-law had her entire desktop plastered with empty folders. Why???? Because she didn’t know they could be renamed and she wanted to name a folder specifically but kept misspelling it. She also wasn’t sure if she could just delete the empty folders and didn’t dare to just try it.
