I home educated one of my children (he has autism and adhd, but went under the radar enough at school that they decided he needed no extra help. Then complained about him not doing work without needing help. 🙄 plus other things like bullying, staff turnover)
I didn't unschool, but knew loads who did. I think it has vastly changed since one of my friends unschooled her kids - screens everywhere now. This friends kids all went to university.
The more recent unschoolers have kids who have sat on screens, and that's all they want to do. They are adults now, like my son, and they are still just sitting on screens. My son did a home education college course at 14, and is in his last year at college, looking at apprenticeships and jobs. Some of these kids couldn't even spell simple words well into their teens. What are they going to do? Are their parents going to support them forever?
Unschooling isn't supposed to be about letting them do what they want all day on a screen. You're supposed to show them stuff, see what they're interested in, expand on that. How will they discover stuff they may like if they're never shown anything outside of a computer game?
The guff I've seen on home ed groups too, about writing reports for the local authority. Trying to make playing Minecraft all day every day an educational experience. Ffs.
Some of them are also completely anti school so look down on anyone who sends their kids to school. My others were very happy at school, so I had no reason to home ed them.
Obviously I'm not perfect, there are definitely gaps in my sons education, but he has had an education, that has suited him when I know school failed him. He loves screens as much as the next teen but has been encouraged to see that there is more to life, there's a whole world out there to explore.
