Been a while (busy busy busy), I happened to check out this TEDtalk. It made me even more self-conscious about how I use PowerPoint as a means to present information and how much jargon there is in both education and mathematics.
I literally stopped it temporarily at:
When presenting your work, drop the bullet points. … Bullets kill, and they will kill your presentation.
and just let that comment simmer in my mind for a few minutes. I was mentally comparing a typical slide that I might use as part of a presentation to her example of a ‘boring’ slide. I can remember when I first started teaching that some supervisors would mark “use of technology” on a walk-through (or other observation) if I happened to use the projector during class to show a transparency. At the time, I kind of thought to myself that an overhead projector isn’t even really technology anymore. In retrospect, this was opinion was largely due to the fact that I am from a different generation of learner. Flash forward approximately a decade, a PC running PowerPoint through a projector is not technology to my students; they’ve been around it their entire lives.
In my opinion, the entire presentation also affirms the efforts of Dan Meyer and others to being with a striking visual that prompts questions and discussion before you bring the math jargon into it. At this point, I should probably admit of all the changes I’m trying to make this year; I’m definitely the least far along on incorporating more authentic problem-solving. Oh well, no one is perfect, but we keep trying anyway.
