In what world is normal life in society a "bubble" but rigidly-structured conformity to professionally-designed programs in a walled-off institution not a bubble?
A student that is placed into a public school has many teachers, with many other student peers from all walks of life that will offer their own perspectives on anything from social issues to academic subjects. Your disingenuous hyperbolic claim that this environment is somehow "walled off" is ridiculous non-sense.
That strongly depends on your school district. Chicago's shittier schools aren't likely to have too many cultures represented. My high school in Texas had a grand total of four black students throughout all four years, and three immigrants - one of whom was me. The rest was white and hispanic southern kids.
But your point is well made - I don't know if that's the sort of thing most homeschooling parents work on.
Honestly, I would love for this to be a thing. But I feel that it is far, far too optimistic. Most people tend to shy away from others that don't fit within their socioeconomic circle if given a choice.
"Kids would you rather stick around the neighborhood today, go to the zoo, or go into the city to a youth outreach program and meet some new friends!"
I'm being a bit too unfair with your point, but the thought of that conversation happening within a family who home schools is pretty hilarious, and unlikely, in my opinion.
Not really.
>have been through different experiences, do different kinds of work, have read different books, have different ideas, and so on: exactly what public school can't offer.
That's exactly what it offers.
