I think your expectations of home school groups are quite unrealistic to be honest.
I home educated, for a time, due to dds struggles with mainstream school. I did work for myself and I did consider it a privilege to be able to.
But the groups were so the kids could socialise and usually learn something along the way. Museum visits, library visits, allotment visits etc.
The fact that you feel it’s up to you to judge how relevant they’re teaching, is really going against home schooling. It doesn’t appear you have spent much time with these people or really understanding me what they are trying to achieve. Perhaps your mention of black history month was met with a bit of defensiveness. Someone new coming in telling them they are missing something, never a goes down well. Especially if they person is quite obviously judging their set up. Or maybe they don’t do black history month, but teach a more diverse history in general. I very much doubt they shield their kids from it being black history month. Maybe they were put out because you have assumed they history teaching isn’t diverse and have bothered really finding out what they are doing.
As a mother who always worked, I think your concern the kids only see ‘trad fem’ and so will be heavily impacted is a bit disingenuous tbh. You are judging women who are staying at home under the guise of concern.
Essentially you want a school. But a school that better suits your child. I get that. My son is autistic. While provision isn’t great and needs improving there is never going to be a way to set up schools that can take children and meet everyone of their individual needs. Who would pay for it? The families? So private education? It’s never going work where the curriculum is exactly what each individual parent thinks it should be. Once you have a group of children in a school, each parent is going to have different opinions.
You would need so many staff to ensure each child’s needs are met, their parents idea of education is met, preferences are met, medical needs are met, social needs are met what you want is almost impossible AND it’s beyond most home educators skills to set something like this up. Home educators aren’t ever going to be skilled enough to open a new time of schools. You would need to seek out people who can do this and pay them. You would need to run it like a charity/business to keep it open.
and most home educators don’t want their kids in a formal setting. When you have a lot of kids in one place, there needs to be formal rules. So home educators wont spend time on this even if they could.
I get your emotional response here. You are scared for your future and your child’s future. But your anger is being Misdirected and you are judging the people who can make home education work for them. Because you can’t find something that works for your child’s very individual needs.
As an aside, I actually believe kids in mainstream school should be learning more about nature and spending more time outside. I think it’s fantastic for kids. Even for a lot of kids with Autism/ PDA/ mental health issues. I really wish mainstream school would include more time in this and doing things where kids are outside more. I think your assumption it’s not that relevant or helpful is incorrect.
