In a post I made a few weeks ago I stated
And some of my students this summer must be from Wannabe Flagship, seeing the way several missed class (and a key review topic) the day before an exam.A commenter asked whether there was any correlation between missing those two classes and doing poorly on the exam. I never got around to blogging it, but I looked at it at the time and the answer was "yes".
Quite a strong one, actually.
100% of the students who were absent on the particular day that I discussed Hairdressing (and were also absent when it was reviewed after homework was returned to them) got zero credit on a Hairdressing problem on the exam.
In contrast, fewer than 20% of the students who were present when I showed them how to Dress Hair got it completely wrong on the exam - and one of those was probably texting under his desk if past observations also applied that day.
Missing the review day was less critical if they were there the first day and also did the homework, but only 20% of the ones who got the Hairdressing problem completely correct were gone that day, while 60% of the ones who got partial credit had missed that day.
Perhaps more important is the subjective fact that several students who had been doing B/C work in the course missed those classes, missed the Hairdressing problem, and saw their grade drop significantly as a result.
I borrowed the "Hairdressing" term from profgrrrrl to stand in for one of the topics in my class.
