Seymour Papert designes the programing language LOGO as a computer language for children. Initially a drawing program, LOGO controlled the actions of a mechanical "turtle," which traced its path with pen on paper. Electronic turtles made their designs on a video display monitor. Papert emphasized creative exploration over memorization of facts: "People give lip service to learning to learn, but if you look at curriculum in schools, most of it is about dates, fractions, and science facts; very little of it is about learning. I like to think of learning as an expertise that every one of us can acquire."
