Stupid divided by inept equals doomed
Today I was asked by my students to give them “that special equation for figuring out what we need to get on the final to get a good grade.” I explained that it wasn’t anything special, the final grade is 40% 1st quarter grade, 40% 2nd quarter grade, and 20% the final exam grade. The again demanded “the special equation,” so I grouchily wrote it on the board, all the while thinking that our country is doomed when 15 year olds cannot figure out their grades. After that, 75% of the students were able to solve for x and go on their merry little ways, but what of the other 25%? Most of those fine mathematicians simply needed a little reminder about the order or operations (Please Excuse My Dear Aunt Sally), but one special little lady needed a little more help than that even. She could not even plug her two grades into the equation that was written on the board without very explicit instructions (”no, no, write ‘.4 times YOUR grade;”), and then needed my help in multiplying and adding, and at one point she added 23 and 19, got -17, and couldn’t see anything wrong with that. In the end we determined she needed a 153% in order to get a D in the class. She asked me what that meant, and I just weakly told her to work “really, really hard” for the rest of the quarter, and maybe she’ll raise her grade enough to pass. I mean, I couldn’t tell her to give up 3 weeks before the end of the semester. Sometimes dishonesty is the solution
