World Science U
This extraordinary site, run by the World Science Festival, offers free videos and lectures about science for every level of interest and knowledge. The site uses the tools of the web in order to create a new kind of online education. Rather than simply placing a camera in the classroom of a lecture that exists somewhere in the real world, World Science U uses innovative tools to depict scientific theories, interactive examples and other elements that help students understand difficult scientific concepts. This approach to instruction greatly separates World Science U from other online learning sites, crafting a unique but helpful form of online education.
