This teacher sent a comment; he or she has figured it out. If the galvanic response skin bracelet will give teachers a high effectiveness rating when students are excited, there is an easy way to game the system and fool the bracelet:
Can this galvanic contraption distinguish between different types of excitement? Sometimes a beautiful new female student joins my class and the young men are visibly excited–about the girl, but not about my thrilling explication of adverbs. If I want to keep my job, do I have to hire supermodels to audit my classes to raise the galvanic excitement levels?
Creative teachers will think of many ways to get their students excited. Suppose you invite students to have a wrestling match in the middle of the lesson? How about bringing out the dice and play a game of craps? Show exciting movies?
Let’s hear how you would fool the bracelet and win yourself a high effectiveness rating.
