Why does this forum appear to want to discourage someone from trying something.
I'm certainly not trying to dissuade anyone from trying the mod, or any experiment. I'm only commenting on the article itself and how they conducted their experiment. It doesn't lend credibility to their claim of actual improvement or difference, only a perceived notion of improvement. And it's cool darscuzlo could set it up so quickly and get results. I see nothing different between the two graphs which goes towards the point that the students will say whatever the instructor wants to hear.
