Dr. Pion’s blurb about exam design and grading<\/a> reminded me of a few things. I taught for the Navy in the nuclear power program, long ago, when the school was in Orlando, Fl; physics, which included applications to plant operations whenever possible, and a class on principles of reactor operation. There are some distinct differences between exams in this context, vs how they were graded when I was a TA. Being in the military means never having to say you’re sorry to students or even explain yourself to them, if you don’t want to. That translates into not having to post or explain the grading policy on exams; the students’ job is to ‘learn the material, dammit,’ not to haggle for points on exams. Students could still put in for regrades, but it had to be for an obvious grading error, rather than for a dispute about how many points should have been deducted for their mistakes. That didn’t stop all whining, but it’s certainly a bonus when you can tell the offender to shut up \u2014 in navy parlance, “Secure that!” (or, “Secure that shit!” Optional for officers, pretty much mandatory for senior enlisted)<\/p>\n

Since the material had a definite application, answers to questions had to display an appropriate level of understanding, which was a factor that could supercede any other policy that had been set up. There was a shorthand for the various types of errors \u2014 the usual suspects, like math errors (ME) or sign errors (SE), and the big red X for anything wrong, but there were others, too, in part because there were always several “discussion” problems, even on physics exams:
\n
\nCE<\/strong> and GCE<\/strong>: Conceptual Error or Gross Conceptual Error, losing at least half of the points of the problem, and possibly all points. This included grossly unphysical answers, like solving for reactor power and getting a negative number or something several orders of magnitude too big or small. If you noted that the answer was unphysical, your calculated answers often reverted to simple math errors. A colorful variant of this (that I never used; it was more popular with the senior enlisted staff) was DAF<\/strong>: Dumb as Fuck.
\nBOD<\/strong>: Benefit of the Doubt. An ambiguous answer that could be right or could be wrong, but contains some correct information. Not something a wise student would put in for a regrade \u2014 BOD goes out the window.
\nS\/G<\/strong>: Shotgun. Blasting a problem with as many answers and\/or equations as you can, hoping that something is right, hoping for partial credit. But you get none, because you haven’t demonstrated anything beyond rote memorization.
\nDR<\/strong>: Dead Rat. This name was an evolution of the dead mouse principle \u2014 the student played with an answer too much and ended up killing it. Usually adding in extra tidbits that were wrong or contradictory, not recognizing that they had answered the question already.
\nABA<\/strong>: American Basketball Association. Your showing is weak and you need to merge with another student to pass. <\/del> Answer by accident (also RAWR: Right Answer, Wrong Reason, for those who tended to growl) As indicated, the work or reasoning is incorrect, but somehow the correct answer was obtained.<\/p>\n

And there may be something i missed, because this was all many beers ago.<\/p>\n

Update: ATQ<\/strong> or ATMFQ<\/strong>: Answer the (MF) Question! You did everything just fine except actually answer the question that was asked.<\/p>\n

Thanks to some former cubicle-mates \u2014 BDJ for reminding me of that last one, and RTS for the prior entry.<\/p>\n","protected":false},"excerpt":{"rendered":"
