I teach high school math and we have seen an explosion in cheating incidents in the past year or so. Students are going well beyond the typical "look at your neighbor's paper" or "cheat sheet". We have students secretly using their cell phones to take photos of graded tests to sell (this was in one of the teacher's with phenomenal classroom management too!), students going to the bathroom during test and using their phone to look up content, answer keys to homework/reviews posted on google classroom by the teacher, or use sites such as wolframapha or simply google to get answers. I was hoping that some of you could share what you do to prevent/curtail cheating in your class/department - especially math/science teachers. We have talked about collecting cell phones on test days --- but there is always going to be the kid who is determined to cheat who has 2 phones - a dummy phone and a real one and hands in the dummy phone. Love to hear a fresh perspective!
