My goal this year is to become even more knowledgeable in Desmos and hopefully get invited to join the Desmos Fellows next summer. Part of the application process requires you to submit an activity that you created. The one that I submitted last year was very rudimentary. I knew that it was a weakness of my application, but am glad that I went through the process last year so that this year my application will be VERY solid. To that end, I thought it would be a GREAT opportunity for me to create my own Polygraph this week. My first attempt was actually pretty good and I was impressed at how easy it was to create the activity (less than 20 minutes). I created the images in SmartNotebook as I am much more familiar with the drawing tools in there than I am with the Geometry tools available in Desmos (another area that I can work on this year). One area that I “improved” for the next iteration this week was made all of my lines MUCH thicker as when the sixteen images appear on a Chromebook they must be very bold to highlight the subtle differences between rays and lines. Overall, I am happy with my progress and look forward to more opportunities to create this year. Want to check out my most current iteration of the activity? Here ya go!
