Would anyone be interested in listening (or having your students listen) to the podcasts and comment on them? My students would then respond to their comments (penpal idea).
They are categorized under "Goochland Middle School," "Goochland High School" and "Goochland Elementary School." Some are password protected, but the majority of the podcasts aren't. If you're interested in listening to the podcasts that are password protected, let me know. I'll send you the password.
