Mar. 5th, 2014 07:13 amHmm, hmm, hmm. On Monday I gave what I thought would be an easy mid term, and it was not so. We've been doing quizzes regularly, 4 of them with 10 questions each so far; of the 46 questions on the midterm, roughly 25 of them came from the quizzes--and even those questions weren't a slam dunk. The top grade was only 40 questions correct. Apparently, the stuff I thought was obvious, was not.
Now, that's after collating the results and realizing there were three questions on form A which almost EVERYONE got wrong, which identified 3 errors on the test key (oops). Correcting for that, we still have a median score of 81%. Which actually wouldn't be bad, except a) I was trying for an easy test and b) the histogram of scores looks like a reverse F distribution, with a peak at 85% and a long tail off toward 59%.
I gotta check with the higher-ups if I'm allowed to introduce a curve when the syllabus didn't say I would. :P Given how many people have missed assignments here and there so far along the semester, I think a lot of them were counting on the midterm to pick them up a bit. I guess a number of them will be doing the extra credit assignment!
