Home-schooling is a legal alternative for parents in many countries, allowing them to provide their children with a learning environment as an alternative to public or private schools outside the home. There are some religious organizations, (such as the Brethren) that rely on community education for all children up to 15 years of age.
The proliferation of the internet and desk top computers have allowed for more options in home schooling and many people in sparse rural areas see this as a better alternative to either long travel or boarding schools. Again, materials, such as supplied by the RobertOMath, can ensure that the student has access to the very best that education has to offer.
The concept of home schooling has led to online university degrees, whereby some universities have more online students than they have students on campus. In fact this trend if it continues may see the first complete revolution in childhood education since compulsory education first began.
Such a paradigm shift will not make teachers redundant, but will see the emergence of super teachers and tutors with outstanding communication skills and the ability to deliver lessons online that can be easily digested and understood by the overwhelming majority of students. (see RobertOMath lessons on long division and number plane for examples of such lessons).
The world is ever evolving, but the changes now are more rapid than ever before, and the pace of change is accelerating. Having said that, the more you change, the more you remain the same, home-schooling was once the norm, it may become so again at some time in the future.
