Co-ops could be structured more effectively.
Paid staff are important.
Merry bands of roving tutors!
Specialization! This is why you need merry bands of roving tutors. And also household services for homeschooling SAHMs. Business opportunity! Way to employ single mothers and older women!
Basically, stop expecting women to do five jobs poorly and then boast about how this will be a way to retake society. Not gonna happen. Early homeschool successes and stories were the result of massive selection bias and in a number of instances outright lying. Many of the people promoting homeschooling via their popular monetized blogs have household help and private tutors for some subjects. But Americans are obsessed with a Walter Mitty worldview where it really is possible in a single 24 hour day to homeschool effectively, clean a 2000 square foot house, cook three full gourmet meals and pay all the bills and do four loads of laundry a day.
So there’s the biggest way homeschooling could be more effective and practical– stop freaking buying into the SuperMom Myth. You can’t do it all and it is ridiculous to even contemplate. Do one thing well and truly. Outsource the rest within your local community.
