Day 106: A Beautiful WhiteboardPosted: March 20, 2014
I just love how this whiteboard shows how multiple representations support problem solving and allow for more complete understandings. This is problem 4 from practice 3 here. I got in the practice this year of making students always find the area of the F parallel vs. x graph for work done, because I like the calculus connection and the more completeness of the definition of work as integrating F dot dx (I don’t use dot product here, but it’s a quick extension if they see it again). Also, energy bar charts really revolutionized how well my students understand energy transfer, particularly when the energy of the system is changing due to work being done.
