I have wondered how the Department of Education GoOpen initiative was going to find content. Aside from the corporations willing to provide infrastructure, I did not see just where the educational content would come from. My thought was that some funds would have to be invested in grants to produce these resources.
The NSF-funded High Adventure science grant program may offer an example of what competitive grants can produce. The content linked here is provided through National Geographic.
National Geographic describes the content in this way:
This set of online curriculum modules utilizes computer models and real world data to bring contemporary unanswered questions in Earth science to middle and high school science classrooms.
