Teaching and improv are more a like than we admit. Classroom or stage, student or audience, our job to help them grow. I just film how I teach.
I always use a script. Though this time it was a bunch of stick notes on my computer.
Nobody want to sit through a synchronous zoom class with a 45 minuted narrated power point.
Nobody wants to watch a 45 minute narrated powerpoint.
Still I am more comfortable in front of the camera than most and get to wrap myself in a safety blanket of privilege.
Some other ideas:
-A Pen cast...literally focus your camera on a pad of paper and just draw your lecture like a chalk and blackboard
-Interview the experts--some of my fav content...conversations with people actually in the field
-Self animated slideshows...to change up from PPT I love videoscribe but expensive
-Make the students make the lectures, approve the outlines and the recordings first to ensure quality (and assess students)
