I am not sure how long this has been around, but Paul Nelson has put together a great resource focused around disseminating OpenCourseWare for K12 schools. The site, K12EdCom already features some gems (e.g., I love the open digital photography course), and I am sure there is much more to follow. Keep up the great work, Paul.
i think online educational content is so good,because you are at home,you have your own time and you have customized education online….it’s really good….
