Teaching children at home is nothing new. Parents, extended family, and tutors have been doing so for ages. What’s new is that in recent decades increasing numbers of people have been teaching children at home as a self-conscious act of protest against mainstream society. Homeschooling is now a political movement. How did this happen? How did homeschooling go from being something that was done as a matter of course by thousands of Americans early in our history, to something that was hardly done at all as more and more Americans embraced formal schools, to something that has re-emerged in our time as a powerful educational alternative?
