Does anyone know of K-12 textbook publishers (or other content creators) that also sell IMS Common Cartridges or other course content that can be imported in Moodle? I'm hitting a lot of dead ends in my attempts to find anything out there...
I too have found few. However, there is another movement in development: LTI - Learning Tools Integration.
and Moodle is listed as one of the members - or something like that.
There are some big players in there including publishers like Pearson.
LTI is present in version 2.2 of Moodle and an add on for the flip side - LTI provider (still in the works of perfecting).
While IMS CC is one way, LTI also provides some interesting possibilities for 'sharing' collaboratively developed content among Moodles.
