Cathy Anderson has a new post giving her thoughts on OER. The post discusses social networking, OER reuse and other related issues. Note that some of the repositories listed in the post are free, but not necessarily permissively licensed. From the post:
I have often heard the statement madeā¦there is no evidence or research that demonstrates that any institution uses OER for development of a course much less a program. There is also no research demonstrating whether or not individuals use OER to facilitate their informal learning and whether or not they have sought to have that learning validated. I have yet to delve into any research so am not certain whether or not these observation are credible or not.
