While teaching Precalculus 12, I had decided to use Desmos (an online graphing calculator) to show graphs of functions.  I was eager because Desmos would be easier/ better than the older graphing calculators (Ti-series), it would let me graph multiple functions to compare and show changes, and I could show the students how to use it for themselves.  This experience is memorable because teaching “driven and smart” seniors can be quite nerve wracking as it is and I had difficulty getting functions to graph because of lack of experience with the software and syntax!  With technology changing so quickly, and no one having the time to become an expert with any specific technology, do the students of today view technological mishaps as  incompetence or an annoyance? Or do they realize this is the norm and see the mishaps as an opportunity to learn how they might have to navigate the software by working through the mishaps as a collective body?
