John Holt (1923-1985) was an American educator and author who criticized traditional public schooling methods. He believed that children naturally love to learn but schools were failing by focusing on right answers, rigid structure, and formal reasoning rather than appealing to each student's interests and allowing for an organic learning process. His books How Children Fail (1964) and How Children Learn (1967) advocated for a more student-centered "unschooling" approach inspired by the progressive educational theories of John Dewey. Holt went on to become a prominent advocate for homeschooling and published additional works challenging traditional education models.
