Sometimes I think there should be a second round of compulsory education, coming in the later years, when we can better benefit from it.
I totally agree about the idea of life-long learning but not sure about the "compulsory" part. Surely, it is precisely because it was compulsory that the education was both poorer and disliked in the first place? Anything that people choose personally to do, as well as anything they have to pay for themselves, is going to be appreciated by them more?
If I wanted to do something more hands on it was fine, but 'A' level education in general studies such as English, Maths, History, Geography etc was non-existent.
You didn't say when you thought this was true, and I agree that there is quite a lot of pottery and life drawing classes at the level of the local council run adult education colleges, and that the opportunity to retake 'A' level qualifications in later life is limited, but it isn't true today that you can't take courses in English Literature, Maths, History and Geography. You need to look at the major universities, to be prepared to pay, and also to do a lot of work online at home.
My course at Oxford was an Advanced Diploma (equivalent to a third year of a first degree) but you can do ordinary Diplomas and Foundation courses, Degrees and Further Degrees. You can do short courses with no qualifications, or you can obtain CAT points (Credit Accumulation and Transfer Scheme) for different courses from different universities and colleges that add up to a qualification.
The Open University allows you to do this in a more structured way, where you can top things off with a summer school.
My caveats would be firstly that these are not very "general" courses, they are specific, so the Literature course would be a specific book in detail, the Geography course on a specific region. Secondly, if you want to pass exams or push yourself, you do need peer pressure from fellow students, so an online course must have some joint discussion elements or a summer school. I did an online course from a Higher Education College in website design about 20-years ago which was just working from a script at home and it was a very boring way to learn.
I regularly receive brochures of courses from my alma maters so I know that
Oxford University Department for Continuing Education have hundreds of such courses, as do
Imperial College Adult Education and
Sheffield University Department of Lifelong Learning. Just do an online search on them.
The other thing I'd add, is that the academic standard of these courses are no less than for an 18-year-old, so for a mature student, juggling work, child-care or other caring, housework, relationships, etc. it is going to be tough. You will also need a decent laptop and they will demand certain software. I think a lot of people drop out. I know some did from my own course. I was only working part-time and I found it difficult. I did get a distinction though, so maybe I didn't need to push myself quite as hard as I did.
If you only want to watch University level courses in a lecture theatre without joining a course, then there is YouTube and Apple University. Alternatively, search online for
Harvard University free courses for a list. There were some good English Civil War History lectures from Harvard that I watched 10-years ago.
