When the curve for this exam was posted, this turned out to be a "C". This was typical of many tests for that course not only for our group of freshman, but it had been true for years before I got there, and not only for that course, but others as well (although somewhat less dramatic). I've also talked with other students from other schools and this, by no means, is limited to Purdue but is an affliction that hits many school (most of them I hear about are big name schools, but that could be just because they are more visible). In my mind, their is no excuse for this. No matter what can be said about the students not working hard enough (etc.) with scores this dramatic some blame *must* be put on the administration. Is it that the kids aren't learning the material, or are the tests bad? Hard to tell I guess, but in a situation such as that, I would feel the same way about cheating as those interviewed did! Sometimes I'm just clearing my throat...

Here at Oklahoma University, it's closer to the "cannonical" curve: A 90-100 B 80-90 C 70-80 D 65-70 F <70 This seems somewhat silly. If 90% of your students do reasonably well (C or better), you've just crammed 90% of the data into 30% of the scale. You've got lots of accuracy for people with F's, and very little for the best. Something like Purdue's scale would make more sense (lots of accuracy for the very best) for a "good" school. Even better, something like: A 80-100 B 60-80 C 40-60 D 20-40 F 0-20 Would seem to give you the same accuracy for all types of students. Comments, anyone?
