I was in a similar situation; my husband supported a home-based preschool, but not elementary school, when my first daughter was born. I think the biggest thing that’s changed his mind is seeing how effective EL really is. He sees me teaching her phonics and addition and subtraction, and he knows that those things are normally taught in kindergarten, and she’s not even two yet, and he starts wondering, “What is she going to do in kindergarten?” So he’s leaning more toward homeschooling, but he’s still worried about socialization.
There’s been a lot of research cited on this thread, which I will definitely when the time comes to make the decision once and for all, but I think it’s equally important, as you said, to have a plan for teaching social skills. I haven’t finished mine, but I’m definitely considering it. Here’s an anecdote that gave me a lot of hope for teaching social skills:
We have a thrift store with cheap books, so I pick up all the parenting ones I see. I just read “Parenting with Dignity: the Early Years,” which I very much liked, and which talked about teaching kids things before the situation comes up, like how to behave in a grocery store or at a nice restaurant (rather than scolding them after they mess up). So I was thinking about teaching opportunities.
Then we went to the park for play group, and no one else from the group showed up, which made my daughter sad. She told me she wanted to play with those kids, pointing to some kids we’d never met. So I explained to her how to walk to them and say, “Do you want to play with me?” I had her practice on me several times, and then we walked over to the other kids. She got shy, but I refused to ask, so she spoke up. She ended up having fun playing with some new friends.
This is very simple, but it’s at the heart of what I think people worry kids will miss out on by not going to school: initiating conversations and acquaintances just because the other people are the only ones available. (And I actually agree that this is one useful school social skill: being able to walk into a meeting or a crowded lunch room full of strangers and sit next to someone and not feel awkward or isolated. Of course, this comes naturally to some people; not to me or my husband, though!)
Interestingly, my mom, who is vehemently opposed to homeschooling, said when I told her about this experience: “You know, you and all your siblings had trouble with that kind of thing growing up. It never occurred to me to teach it, and maybe talk to some parents in advance and stage opportunities for you to practice.” I’m storing that comment up for when I tell her I’m going to homeschool. I think with thought and care, we can teach our children those kinds of outreach skills even without the school environment, which forces kids to do it.
