One was the lack of social interaction, and the other was the fact that I am not a teacher and am not qualified to teach.
I have to think Venice can't actually have come too close to homeschooling because those two questions are fairly basic and a little research would have dealt with them quickly.
The first one is an easy one.
I'm quite sure that if most parents with the socialization concern gave a few moments thought to all the socializing their children do outside of school they'd see why homeschoolers look puzzled when the matter is brought up. In the last week my daughter has gone to soccer practice and a game, a school dance with her cousin, performed in a concert, and has had neighbourhood kids knocking on the door nonstop. Tommorrow night she heads out for a Girl Guides camping trip to a horse farm (Yes, I know you all just winced at the thought of me dealing with a 9 year old girl who's been bouncing off the walls with excitement for the past couple of weeks. Yes, I know I have your sympathy).
School is simply one place where socialization happens. When a kid doesn't go to school, other oppotunities for socialization present themselves. Very often they're opportunities schooled kids might not have any chance to experience, like my daughter's work as a helper at a preschool where she mixes with younger children and adult teachers. I can't make the case my kids will get the same socialization as schooled kids but that's not something I'm interested in anyhow. It will be different but different is not a bad thing.
The teacher thing seems trickier on the surface but really isn't. In the past I've given my reasons for not worrying about my lack of qualifications but another thought often reassures me. I haven't yet met a teacher-turned-homeschooler who's claimed her training was indispensible or even of any great use when it came to homeschooling. I've even known a few who claimed it was worse than useless and even got in the way. The simple fact is that homeschooling is to teaching what carpentry is to working in a furniture factory. Yes, the carpenter and the worker both produce furniture but the environment, the skills and even the basic tools used in each situation may be dramatically different. The training one requires may hamper the other.
The skills that have been useful to me in homeschooling are the ones I developed as a parent, the ones most parents use when teaching a child to ride a bike, fish or when tutoring them in algebra or history so when Venice asks later:
Should parents be required to take courses certifying them to teach, or should they be taken at their word that they are qualified?
...My answer would be that they should be taken at their word. If the state assumes I have the skills to parent then they should assume I've got what I need to homeschool. I think this would be more obvious if those calling for certification actually took a look at how homeschooling often works rather then comparing apples and oranges.
Head over to Mommage if you've got anything to share with Venice. Her post is a polite call for opinions.
