Mitchel Resnick
Mitchel Resnick is a learning scientist at the MIT Media Lab and the principal architect of the Scratch programming environment, which has become the most widely used platform for introducing children to computational thinking. Resnick was a student and intellectual heir of Seymour Papert, and his work extends Papert's constructionist philosophy into the era of networked, social computing. Before Scratch, Resnick developed StarLogo, the parallel Logo dialect that introduced the concept of massively multi-agent microworlds to educational computing. Resnick's theoretical contribution is the concept of "lifelong kindergarten" — the argument that creative learning environments should preserve the playful, iterative, project-oriented spirit of kindergarten throughout the lifespan. This is a radical claim about human development that treats play not as a developmental stage to be outgrown but as a permanent mode of creative engagement. The tension in Resnick's work — between the deep, body-syntonic intimacy of Papert's single-turtle Logo and the social, remixable, but more abstract world of Scratch — is a tension he has not fully resolved.
