Yes. Nevertheless I needn't. At the high school level there are community college courses available to provide these services in addition to other home schooling parents who are qualified to teach these courses in groups to other children. I may do that at some point - teach a group of high school kids physics or realistic drawing or cooking or ...
Additionally, most of my learning in high school was self-taught by the text books and practical experience. I got very little from the lectures & the teachers never personally helped me. Lectures can be purchased if need be, and text books are easy to acquire, as are lab supplies. Kids who are schooled at home are very good self-motivators and learn on their own with facility.
Also, it may be noted that not all children are headed in such a technical direction - most, I'd guess, are not inclined toward this type of study at all, especially where the parents are not. Children who have aptitude for fine art are usually born to artists; those with a thirst for science or math are typically born to those with like interests. I, for instance, was born to an artist and an engineer, and I am both and more - but along the same lines of interest. I have siblings who are artists, one is a teacher, one a computer/media specialist, and another who is a factory worker. But none of my siblings was interested in accounting, for instance. I have a friend whose parents have no particular affinity or aptitude for anything technical or speciallized, but they can add. She loves accounting.
My point is that not all subjects need to be addressed in the home. Some may be addressed through outside influence (mine take dance classes, for instance), and not all need to be addressed at all.
A parent who is going to begin home schooling needs to make to two very honest and frank evaluations before beginning.
- What are my child's needs, strengths and weaknesses?
- Can I met all of those needs, strengths and weaknesses?
Just be honest in your evaluation and do whats right for your child.
As for evolution, use the secular text books so that your children understand the theory that most of sciences prefers. Then take the next step that you will never see in a public school. Teach them where the theory works such as a species adapting to its environment by changes in color or some other minor change in appearance. Then teach them where the theory completely falls apart such as its inability to explain new species and its utter failure to address biogenesis (creation of life.) Then, when they leave home and enter college, they will understand why they believe what they believe.
