Many families choose to educate their children on their own, rejecting the public education system.
.... I don't think many families do this. Of course there are some families that prefer home schooling. So, I suggest you to replace "many " by "some".
There can be plently of reasons for such decision but many parents do not take into considiration the importance of socializing which is provided by school.
Although there can be many valid reasons for such decisions, the parents need to understand that social skills are as important as theoretical knowledge for their children. Schools are the best places for a child to learn social skills because they provide such environments that ordinary households cannot.Personally, I belive that communicationg with other children is essential for every kid and therfore home education cannot affect child's life well in most of the cases
Therefore, I personally believe that schools are a better option for educating children. .... better express your opinion simple and direct.
