Guest Speaker Reflection
One of the misconceptions that surprised me was in the video Dr. Edmondson showed. It was where the student had trouble understanding that gases have weight. I think the hands on activity of showing the student dry ice was a good idea but it didn’t click. I think maybe our experiment we do in front of the students will better show how carbon dioxide has weight, even as a gas.
I think students who don’t get the correct answers at a young age create their own, and those are hard to break them from. Nobody tells you when you’re young that the air weighs something. Or when teachers use metaphors like the plant breathes in CO2, those are hard to change. They are effective, because students really remember them. But then that train of thought is really hard to change later. Sorry there’s a watermark on this picture, but I thought it fit what I’m talking about here. Wouldn’t it be easier if we taught kids the real reason for things at the start?
I think I will try to demand classroom attention by asking people questions. I don’t want to put people on the spot, but it might force them to be thinking about what I’m talking about. I may resort to asking people directly if I don’t get any volunteers, or if I get the same volunteers over and over again.
Also, in the lesson Dr. Edmondson talked about preparing a cheat sheet, which I think I am going to use. It seems like a good idea for me, so I am not looking at the screen the whole time. I have had to present Pecha Kucha style before (Where 20 slides cycle at 20 seconds each) so I feel pretty comfortable speaking without looking at the slides, but I had flashcards organized for each slide. Also, I am trying not to put too much on the screen, but it is hard, because there is so much information! I watch a lot of TedTalks so hopefully some of that will sink in, but I also found this website that outlines different styles of presentation, and video clips of people presenting (who are really good at it) http://viget.com/inspire/presentation-styles-trends-trendsetters. Watching some of these different videos will hopefully help me understand how to limit what I put on the slide, and how my ideas should flow when I’m talking in front of everyone.
