My sister homeschooled both of her children until they got to 10 and 11th grade. (This year). She is/never was the scholarly type, barely making it through high school. But, both of her children are doing really well in high school, so home schooling even with no credentials can be successful. I know that she did purchase the dvd's for the cirriculum she was teaching them once they started to get math questions that needed more explanation.
They are great kids and I think home schooling is a wonderful option for those who feel they could do it. We all really worried about the kids when sis said they were going to public school this year, but they have done really well academically. Now, the one area that my niece is having issues with are a little bit of immaturity or naivety might be the better word. They are a very religious family, my niece wore jeans/pants for the first time in 17 years this year. She has not been exposed, ever, to anything. I don't mean that has a bad thing, only to mention that for my dn this is an area that she struggles with on an emotional level. Its hard to be 17 without being able to fit in so well. Last night my sis told me she finally said that dn could go on a trip with her family members to WDW over Christmas break and she is having a hard time. DN and nephew have never gone anywhere without their parents.
Trust me, all kidding aside..my sister is probably the last person ever who should have homeschooled her kids. However, the kids were quick studies and didn't need a lot of hands on. So, depending on the children and what learning style they do best with it might actually be succesful. My personal thoughts are that only people with a college education or at least academically inclined should do the home schooling. But, my sister is one of those people who would prove me wrong!
