omg, my least favorite thing in the education literature: Prof does a 'study' where they teach a class with both hands vs with one hand tied behind his back. Each class has 200 students, and he finds that the one-handed class outperforms the two handed class with p=0.045 with N=200... And I'm like NO! This is basically an N=1 study because the teacher is common across both classes. Have you never heard of pen-effects?!?!?! Unfortunately, fixing the problem in the study design means convincing a bunch of your friends that one-handed teaching might be better and engaging in an experimental study together... But that's obviously way too hard. |
