The subject of homeschooling is a tenuous one, as mentioned above, but it most certainly has its benefits. I have first hand knowledge with the positives and negatives of homeschooling, as both of my children have tried it, although for different reasons. My son was born with an immune deficiency problem, which caused him to miss out on a lot of school. This in turn led to him falling behind constantly. In order for him to get back on track, we enrolled him in home schooling, both private and public venues. My daughter, on the other hand, chose to participate in home school because we had just moved far away from our home, and she was experiencing bullying. I will elaborate the two varying experiences later in my post. My being a credentialed teacher helped, but I do not think it is necessary for the parent to be a teacher. Of course, you must sit with your child, according to age, in order to supervise their progress.
There are several aspects that contribute to the ultimate success or failure of your home school experience. Be careful to read the points that I suggest in order to be adequately prepared to embark on a home school adventure!
First, make certain that it is the best option for your child or yourself, thinking of all the pros and cons, such as the isolation factor (you will have to work hard to include your child in outside group activites). Some home schools offer meet ups or field trips in your specific geographical region. You also need to consider how much time you can invest in helping your child get started, and how much time you are willing to put into helping him/her.
Second, make sure you contract with a reputable home school system. They should provide text books, certain supplies according to class content ie: art, head sets for language classes, etc... Each school has their own standards, and it is really up to the parent to do the research and choose accordingly.
Third, ask yourself if you and/or your child is a self starter. Home schooling requires that a student be dedicated to fulfilling their assignments according to prescribed or self-imposed deadlines. If your child simply needs a lot of supervision and prodding to do the work, a lot of frustration is going to happen for both parent and child. For example, my daughter is not a self starter and lacks motivation at the best of times, so home schooling turned into a living nightmare for her. My son, on the other hand, was much younger, which meant I had to sit and supervise much of the work. It won't be easy if you don't have the luxury of being a stay at home parent.
Fourth, you need to keep in close contact with your childrens' teachers, almost more so than if they attended regular school. Each month there is typically a parent/teacher check-in call wherein you discuss progress and ask questions about issues you may be experiencing.
Overall, home schooling can only be what you put into it. It can be a blessing or a challenge! Hope this helps.
