I think 'enjoyable' is completely subjective. For instance one of the older home ed boys I know, isn't academic at all. But through the freedom of really getting to know himself and what he likes and doesn't like, has decided that he would really like to be a bin man.
There will always be jobs that are considered mundane and there will always be people to fill them. At the very least young people should know if they'd prefer to work indoors or outdoors. If they would like to be customer facing or work alone. What time of day are they at their most productive.
If we could acknowledge and develop these differences, then there is a chance of happiness.
However looking at how the world is changing with the fast development of A.I, a lot of jobs won't be there in 10 or 20 years. So we have an opportunity, to really look at what skill sets will be needed and develop them. Being a creative thinker is increasingly important to succeed.
I just want my kids to have the freedom to develop their strengths and to really pursue their own interests. Most state high schools (certainly the ones local to me) primary role is to prepare kids for the local labour market. I don't want that for mine.
I think primary schools do better than high schools, but they are still way off. Pre schoolers naturally explore the world around them. They are natural scientists, mathematicians and philosopher's. As the years go on children have less and less time for exploration. They are bombarded with facts that they have to learn, in a certain order. It's really not necessary. Lots of home ed kids are very academic. They go on to university and succeed in their chosen field. There are also the kids who come to it after attending school and suffering trauma, but again, that's another thread.
It's uncomfortable reading for anybody with kids in school, so I don't expect the majority to agree. That's OK, I'm not trying to convince anybody. What I would like to see instead of parents or teachers arguing for arguments sake, is for them to recognise that this is a problem with the education system in the UK and to speak out to improve it. There is a reason I know of so many ex teachers now home educating their own children.
