Germany is incredibly slow to go digital. I still see the kids on the train in the morning doing their homework in exercise books and using reference books.
There is a fund to "digitse" schools, but that is very slow, haphazard and not very well coordinated. Even with the pandemic, many schools just don't have access to technology. The Bund (federal government) has set aside several billion for the digitalisation of schools, but that is a state prerogative. That means that the schools can't simply dip into the fund, they have to go through the state and most states haven't worked out what they are doing yet.
Some want to use Google or Microsoft services, even though both would not be GDPR compliant, so cannot be used. Some want to issue laptops and some iPads. Some are using open source platforms, like Big Blue Button for conferencing, others Teams and Zoom, even though they aren't compliant.
The schools don't have Wi-Fi or cabled network access for the most part. The teachers are often just given a laptop and told to get on with it. Many have no idea what they are supposed to be doing, because they have had no training, yet they are supposed to set up online classes and make material available, whilst at the same time ensuring the class is secure. There is some money (see above) for infrastructure, but little to no money for administration of the tech.
Then there are the pupils at home without any resources, no laptop, no tablet, or have PC, that doesn't have a camera and microphone. Then there is the broadband situation. Both parents in home office, plus 3 kids on a 10mbps line all having to work at the same time... If they even have broadband available, which isn't a given.
A lot of teachers are anti-online learning, as are a lot of students. Studies have shown that the average reading and comprehension level has dropped dramatically (25%, I think) over the last year. Social interactions are the biggest problem, with children growing up not knowing how to play with each other or how to share things.
Digital learning is all well and good, but it is an adjunct to "real" learning. Social skills, learning to be with other people, learning to cope with face-to-face situations etc. Learning to read out loud, in front of people - the digital solutions provide ways for the shy pupil to talk directly with the teacher, without the others listening. This might help somewhat with their reading level, but it is an appauling step backwards for their social skills and "getting out of their skin".
I was very shy and hated having to stand up and read or give answers. But it is something I learnt to overcome and that helped going forward in life, where I suddenly had to stand at the front of a room full of managers and give presentations, or a hall full of people giving a lecture or doing a Q&A with them. I still find that scary and difficult, but without the valuable lessons I learnt in school, I'd have be even worse off.
