Here are my slides for my presentation: “Moving Beyond Textboks: OER in Support of K-12 Education,” presented at SXSWedu, March 2012:
I have also put together an “OER Starter Kit” aimed at OER newbies, available here, as a basic set of introductory links.
I am looking forward to this presentation this morning! 
OER is a great support to K-12 education, as it provides teaching and learning materials free of cost. With the emergence of OER (Open Educational Resources) online education will definitely get a great push. CK-12 Foundation and Khan Academy contribution to OER is remarkable. Thanks
