Seymour Papert, a visionary educator and mathematician who well before the advent of the personal computer foresaw children using computers as instruments for learning and enhancing creativity, died on Sunday at his home in Blue Hill, Me. He was 88.

His death was announced by the Logo Foundation, a nonprofit educational organization that he co-founded. His wife, the Russia scholar and author Suzanne Massie, said the cause was complications of a series of kidney and bladder infections.

Dr. Papert (pronounced PAP-ert), who was born in South Africa, was one of the leading educational theorists of the last half-century and a co-director of the renowned Artificial Intelligence Laboratory at the Massachusetts Institute of Technology. In some circles he was considered the world’s foremost expert on how technology can provide new ways for children to learn.

In the pencil-and-paper world of the 1960s classroom, Dr. Papert envisioned a computing device on every desk and an internetlike environment in which vast amounts of printed material would be available to children. He put his ideas into practice, creating in the late ’60s a computer programming language, called Logo, to teach children how to use computers.
