Proverbs 6

20 Both mother and father are to teach their children. Public or private schools should provide supplemental education, but the most important lessons in life should come from the parents. Most schools do not teach morality in keeping with the Bible. Even fewer will teach children about God properly, if at all. It is up to the parents to teach their children about God and the sound moral principles that please Him. The parents should also teach their children about proper relationships, respect for authority, and critical thinking.

It is also important that both parents be involved. Fathers in western society often leave this responsibility completely to their wives. So many studies have shown that children of both genders have more problems if there is no involved father figure in the home. In some cases it can't be avoided (death or divorce, for instance), but this does not automatically mean that the single parent can not raise a child successfully. It just becomes more difficult.
