I really struggled with this assignment. Not so much with the recording of the interview, but with editing and trying to add music. For whatever reason, I coul not get Lame to work so I was unable to edit  or trnasfer to a MP3 file. Hopefully, you don't mind the few seconds where my cat thought he'd give me his two cents.
As an assignment, I enjoyed talking to my "students and hearing what they had to say; whether they struggled with misconceptions or had a pretty firm grasp of the material.
I can see this being a valuable assessment tool as long as time allowed for it. It could be an interesting assignment for a teacher toallow their kids time to interview fellow classmates or grade level peers (perhaps even including their parents) to test their knowledge, write an article for the class newsletter or even to help build their social-personal connections and also, to introduce themto public speaking without having to speak in front of the class.
