John Holt books
John Holt coined the term unschooling. He began researching what helps and hinders learning with an eye towards creating better schools. He eventually realized schools weren't interested in the changes needed to support children's learning. He then turned to supporting homeschooling parents who wanted to help their children learn and not just bring school home. If you read them in order you can see the evolution of his thinking.
