One of the true visionaries in both the computing and the educational technology community, Seymour Papert is in critical condition after being struck by a motorbike. Papert invented Logo which turned millions of kids onto programming. He was one of the proponents of Constructionist learning, which has a powerful influence on SLA and all of the project-based learning folks, and lately, he’s been a consultant on the One Laptop Per Child project.
For more information about Seymour Papert, I encourage you to read Andy Carvin’s Prayers for Seymour Papert post. And I’d like to add my prayers to the mix as well.
