Seymour Papert was a South African-born mathematician, computer scientist, and educator, best known for his work in artificial intelligence and education. He co-founded the MIT Media Lab and developed the programming language Logo, which was designed to teach children about programming and problem-solving through engaging activities. Papert's theories on learning emphasized the importance of constructionism, a concept that suggests learners construct knowledge best when they are actively involved in creating tangible projects. His ideas have influenced educational practices and technology integration in classrooms, promoting a hands-on approach to learning that encourages creativity and critical thinking.
