> It took becoming an adult to learn for myself that I enjoyed learning. My school was not learning
This is why I stuck with home educating up to GCSEs. I wanted my kids to enjoy learning and they do. They have a very wide range of interests and good academic results and IMO are better prepared for A levels and university than they would have been at school (even really good schools).
> find it hard to think of school as anything more than forced internment for children while their parents go to work,
This is why we have so much after school stuff and breakfast clubs. Yes, it means some kids get fed in the morning, but a lot of them seem to get given junk food.
> for those saying it was good for socialisation with other children
IMO home education is better for socialisation. What skills do you learn from meeting the same group of people your own age in the same place everyday? My kids had more time to do things by themselves (anything from going to a shop to taking a bus to meet up with a friend). They did (between them) guides, dance, sea cadets, sailing, D & D, art classes, singing classes piano classes, drama, stage fighting and more. They had both remote (which develops a useful skill set these days) and face to face tutors at for some GCSE subjects. it would be really hard for kids tied by school hours plus home work to do as much.
> the endless chasing of metrics has made even the tiniest amount of joy that could exist in school- Non-existent.
The chasing of metrics has been a disaster. My younger daughter is at sixth form college for A levels and it has deteriorated since her older sister went there. it is still good but they have become a lot more rigid and I feel they are less focused on students best interests and more on the metrics.
I went to one of the best schools in the UK (consistently top 10 academically), with no bullying problems, no corporal punishment (it had abolished it in Victorian times IIRC), excellent facilities - and I still think my kids had a better education than I did
