maricopa learning exchange via SiT
Quote: "The Maricopa Learning eXchange (MLX) is an electronic warehouse of ideas, examples, and resources (represented as "packages") that support student learning at the Maricopa Community Colleges."
Comment: The "packages" presented are basically learning objects...I like the template used for uploading/defining a package - simple, basic information. As a visitor, you can browse the packages, but you can't create an account to enter content into the system. Also uses RSS for syndicating new packages (a concept I first heard Stephen Downes mention several months ago).
