I can imagine any part of Broadcast Video Production that could be taught online would be any theory-based section of the course. Reading and writing seem to be most conducive to Elluminate learning nature. Unless there is the possibility to show the students how our editing program works, we would be limited to what can be shown on the whiteboard. One activity I could do is the Morse Code activity I do durng History of Mass Media. The students would be broken up into break out groups where they would translate a sentence into Morse Code. There they would practice "speaking" their sentence in the "dit, dah" method, or type it on the whiteboard. When reunited with the entire class, the other students would raise their hand if they can figure out what the sentence is.
I have actually offered to my students online learning similar to the ULearn modules. I told them that they can do the reading and activities at home so we can have more time to apply the theory in class. NOBODY was interested. Not even the most gung-ho video students. I think typical high schoolers want little to do with after-school learning. But that doesn't mean we can try.
