Logo is 40 years old

"What is Logo?

"Logo is the name for a philosophy of education and a continually evolving family of programming languages that aid in its realization."
- Harold Abelson
Apple Logo, 1982

This statement sums up two fundamental aspects of Logo and puts them in the proper order. The Logo programming environments that have been developed over the past 28 years are rooted in constructivist educational philosophy, and are designed to support constructive learning.

Constructivism views knowledge as being created by learners in their own minds through interaction with other people and the world around them. This theory is most closely associated with Jean Piaget, the Swiss psychologist, who spent decades studying and documenting the learning processes of young children."
