Podcasting Rubric possibilities

http://www.uwstout.edu/soe/profdev/podcastrubric.html  I've been searching and searching for structures to help me with podcasting.  I want to make sure that when I utilize this instructional strategy that it is useful and provides leverage learning.

Thought this website might present a possibility...although I think this is much too ambitious for routine projects with my 6th graders, I do think it could be something we aspire to be able to meet by the end of the year.
