Academic Earth
http://academicearth.org/
Academic Earth is an organization founded with the goal of giving everyone on earth access to a world-class education.
As more and more high quality educational content becomes available online for free, we ask ourselves, what are the real barriers to achieving a world class education? At Academic Earth, we are working to identify these barriers and find innovative ways to use technology to increase the ease of learning.
We are building a user-friendly educational ecosystem that will give internet users around the world the ability to easily find, interact with, and learn from full video courses and lectures from the world’s leading scholars. Our goal is to bring the best content together in one place and create an environment in which that content is remarkably easy to use and where user contributions make existing content increasingly valuable.
We invite those who share our passion to explore our website, participate in our online community, and help us continue to find new ways to make learning easier for everyone.
