John Holt was a teacher who wanted to make school more fun and interesting for kids. He thought that traditional teaching methods, like memorizing things and taking tests, made kids bored and unhappy. Instead, he wanted kids to learn by exploring and discovering things on their own.
He believed that kids are naturally curious and want to learn, if we just give them the opportunity to do so. Holt thought that schools should be more like playgrounds, where kids can have fun and learn at the same time.
He also believed that kids should have more control over their own learning. Instead of teachers telling them what to learn and how to learn it, kids should be able to choose what they want to learn and how they want to learn it.
Holt's ideas have influenced many teachers and schools around the world, and his legacy is still felt today.
