This post is about me in home school 15-16 years ago. I'm sure things have changed
I was homeschooled for the last year and a half of high school, and I honestly enjoyed it but I don't think I actually learned much. Quick back story, my parents brought me to Chile when I was 7, and we stayed there for 8 years, with two years back in the States at various intervals. The school I went to was set up for other kids in my situation, so honestly like 50 people in the entire school.
I honestly caught on quick to everything so my basic and intermediate math skills are great, but towards the end in homeschool I was given the option to kinda take whatever I needed to to get a diploma. And that screwed me for college. I went in being great at the basics, but since I went to a really weird school, then homeschool, I was basically stuck in basic classes trying to figure out what the hell everything was.
Now of course my situation is rare, and I graduated in 2001, so I'm sure it's different. But the curriculum at that time was so bare, and kind of just let the child do whatever with almost no supervision. I'm really sad I didn't try harder but I was a teen who would rather have fun than focus on studies
My niece is in homeschool now due to some bullying issues, and from what I've seen (helping with homework, or reviewing tests, etc) it's changed a lot. Her program has a gym Program where kids can play sports together, and even has a nice volleyball and basketball program.
I'm guessing it's changed, but my two cents would be that in any homeschooling program the parent has to be at least twice as invested as the kid. I love my parents to death, but my education has really really screwed me in a lot of ways.
I'm smart, but if you don't learn the basics of things, it's hard to succeed in higher education.
One thing that might help supplement home school learning is things like Khan academy. I'm 32, and have been using them to fill in gaps in my knowledge for about a year now. I think at a current homeschool level, supplementing with something like Khan or a similar program would be incredibly valuable.
