I don't see the IT / computing tuition to be such a problem, to be honest.---- The only thing lacking is some sort of centralised initiative.
I think that's what I'm trying to say. It's not just about teachers stood in front of a class - like everything else in the school system, that's the old "how it's always been" approach.
As I said upthread, my son did an Open University cyber security module online. I was really impressed with how well it had been programmed. It really was a "self study" software, where you had to do various things, like watch a video, read an article, etc., - you couldn't progress until you'd done it, and then you'd have end of topic tests, again where you couldn't proceed until you got a high enough score - the tests being a mixture of multiple choice, entering words, and even clicking on the right part of the screen during videos. My son said he actually found it enjoyable as the learning activities were so varied - he did an entire section whilst he was trailing us around a shopping centre!
Last month I did a couple of online courses to teach myself new accounting/payroll software. It turned out to be very similar and I was very impressed. Same idea - you watch/read snippets, then you have to answer some questions and then you move on to the next section, etc and then you have final exam encompassing all you've learned - if I hadn't got a high enough score, I wouldn't have got the accreditation and would have to go back to re-do the sections I failed on. I found it really good and far better than having a "human" sat next to you showing you how to do it.
Best thing with this kind of learning is that the "marking" and progress is all available at the touch of a button to whoever is supervising.
This is the future we need to be working towards, so that the majority of capable/behaved pupils can progress at their own pace, leaving teachers to deal with the minority who are struggling or disruptive and to deal with the things better suited to "class" activities like science practicals etc.
It seems that during the last 40+ years we've not really moved on much beyond "chalk and talk". Yes, we've had loads of initiatives, lots of faffing around with exams and curriculums etc., but we're still "chalk and talk" but now with a whiteboard, and we have photocopied scrappy worksheets instead of purple duplicated ones.
And no, I'm not blaming teachers for this. State education has been badly managed by the so-called education experts, unions and politicians for decades and sooner or later it will have to be modernised and made fit for the future.
