Just as some kids who go to conventional schools develop better social skills than others, the same holds true for home schooled children. If parents want their kids to be well socialized, and not just well educated, they have to pay equal attention to both important realms. A parent may not necessarily realize the impact of neglecting to ensure a healthy exposure to social opportunities for their child.
Shy children may not express any need for socializing, but this doesn't mean it's not important for them. In that situation, then the child's social development could be stunted and the antisocial behavior reinforced. It's essential for parents to recognize the importance of exposing children to social situations. Parents need to include as many relevant and healthy outside social activities for their children.
Many parents who home-school their children are aware of the concern regarding developing healthy social skills. So naturally, they work hard to make sure their children have adequate opportunities for social interaction. In fact, there are many options for including direct and more social types of excursions that are a part of the child's education. Many homeschoolers are heavily involved in extracurricular activities in their communities. The same thing can not typically be said about children in public schools. Their parents aren't as concerned about finding such opportunities for healthy socialization, so they don't make the effort to encourage their kids to participate.
Maybe you have heard of 4-H clubs, and they have existed for many decades. They offer many clubs for kids to join, based on their interests. All your children can get involved if they're interested. Also, 4-H clubs do not cost anything to join, and that can be a great way for your children to meet others. Keep in mind that children network to a greater extent than years ago, and the internet is largely responsible for that. So it is more natural for the kids your children meet in 4-H clubs to introduce them to their friends.
There should be other considerations made, but there seems to be a trade-off in terms of the degree of socialization. The homeschooler can be spared from the many types of bad social encounters found at public and private schools. This can be a major significant fact when you consider the possibility of a damaging institutional school environment. Socially disadvantaged students would find this especially applicable in their public school. There are many positive and healthy advantages experienced in the home and they have far more of an important impact.
This has been an ongoing debate for a long time. Both sides will always have good points to support their stance. Parents of children who are homeschooled need to ensure that they have access to healthy social outlets. The social outlets will not be that difficult unless, of course, the family lives in a more remote location.
