Today I put the finishing touches on my presentation for the Careers in Mathematics Conference that will be at Millersville University tomorrow. (Even as I am blogging, I am making a few more changes to my presentation slides!) I am hoping it goes well, but I always get nervous when it comes to presenting. Although I had put the finishing touches on my presentation last night, I still did more work on it at school today. A 50-minute session with time for reflection and hands-on learning on the part of the participants is very challenging. I have a co-presenter with me, Bob Lochel, and I am very grateful that he will be there for back-up. What's planned for the presentation? Quite a bit. Reflecting on the role or purpose of technology in math class. Crowdsourcing some data to make some predictions with the help of desmos. Letting participants see Desmos Activity Builder from a student and teacher perspective. And finally, encouraging participants to take steps to incorporate desmos into their teaching.
