Thanks to Sarah at Iris Connect for posting the whole of my TeachMeet Takeover talk at BETT back in January. I spoke about Essential Digital Media for your whiteboard. I also gave a modified version of this presentation at the Teacher2Teacher conference 2011 in Alberta, Canada, and also to the World ORT charity in London.
Here it is in all its glory 
Apologies for the sound being a little flakey, we were fighting a very noisy stand next door and I broke the headset mic at one point and resorted to shouting.
