homeschooling is certainly a better way, provided you do it properly. You can start with http://www.khanacademy.org to teach your son/daughter basic mathematics, and some sciences and let them do the exercises there.

Public education is not education, it's a place for government to brainwash your children, torturing them mentally and shaping them into the way they want them to be - such as becoming docile, becoming passive, becoming aggressive etc. They lose their spirit and passions because each children has different disposition and their talents. The teachers in the public school are of low-quality one because of the education system which renders them so and another because of them not being passionate (majority of the teachers become teachers because it's a job that guarantees silver spoon in the mouth, especially in public school).

Imagine the public school as a kind of factory. You send your children which are raw to them, and they process it and the final product will be determined by their quality of processing. If you know the teachers are good and then it's reasonable that you send like, like the ancient times, the rich people they sent their children to private institution to learn from those wise and knowledgable teachers, they never sent their children to be taught by someone whose quality is unknown much like what parents always do now by sending them to public school ( they don't know the quality of the teachers, so you can imagine what kind of finished product your children your be). It is not hard to see why the majority of the teenagers today are drop-outs or someone who just take learning for granted. Did badly in spm, then get to study in some private college , studying some dismal courses which did not interest them at all or some end up dropped out during secondary, some stopped it after spm. This happens not because they are stupid or something, it's because their spirit is all hurted. Remember each children , upon growing up, will develope some interest in certain subjects and some will have their innate interest and talents. If these is not taken carefully, they might end up giving up themselves especially when they are repeatedly forced to study things they never like.

In public school, kids are bombarded with many subjects to study, homeworks, peer pressure, parental pressure ( some parents who do not have love will beat up their kid and reprimand them for doing badly in examination while it's actually the fault of the public education system ) and mental torturing. Nothing hurts the spirit more than telling the kids what to do and what not to do. Imagine getting such treatments for 13 years of time. and you can see the finished product from the factory of public school.
