Not to worry, the presentation is archived online.
I think all educators need to start paying attention. The dynasty of the textbook is coming to an end. I was introduced to resources such as CK-12 Flexbooks, Connexions, OER Commons, CLRN Free Digital Textbooks, and the Flat Classroom Project. With all of these free or inexpensive, customizable resources - what it the draw of the typical textbook?
Open Educational Resources are all about sharing.
In a brave new world of learning, OER content is made free to use or share, and in some cases, to change and share again, made possible through licensing, so that both teachers and learners can share what they know. (OER Commons)
