Since this thread is back, I have a doozy from the end of last semester. For my big Astro class I give multiple-guess exams on bubble sheets. So this guy came in saying that he thinks there were “a couple” of questions on his test that were marked wrong. He pointed out a question on his bubble sheet and said, “See, this is the right answer, but it got marked wrong!”
Problem: The machine that scores the exams doesn’t mark anything right or wrong on the sheet. It only prints the total number correct in the margin. The student has to go to the answer key that I post online, and compare their answers to the correct answers. “My score was 40/50, but I can only find eight questions that were wrong,” would be extremely suspcious, but “This particular question was ‘marked wrong’,” is an obvious attempt at cheating
The bubbles are filled in with #2 pencil, of course. And for this question it was easy to see that a different answer had been erased, and the correct one marked. Of course he could have changed his answer during the exam, and there’s no way to tell by looking at the paper whether it was changed before or after but . . .
The dip obviously expected me to say, “Yes, it is clear that you do have the right answer and it was unfairly marked wrong. And I know this particular question was marked wrong because . . . you say so. Yes, that is good enough for me. +1 points for you!”
He obviously did not expect this: I said, “That’s very odd. Let me see what answer the computer recorded for that question,” and pulled out the printed report I get with every batch of exams.
He immediately began to backpedal. “Oh. Uh, you have the answers we put? Um. Neat. I, uh, don’t even really, um, care about my grade. I, uh, only wanted to know whether the answer was right or wrong for, um, when I study for the final.”
I found his name in the report, and examined the answers recorded by the computer. “Hmmm,” I said. “This says you had marked B for that question. And it look like B has been erased on your bubble sheet.”
He was panicked. Never saw this coming. He stammered, unable to think of a good lie.
Now, at this point I could have said, “CHEATER!!! CHEATER!!! CHEATER CHEATER CHEATER! I CAN’T BELIEVE YOU TRIED TO PULL THIS CRAP! DO YOU THINK I’M A MORON? YOU FREAKING IDIOT! YOUR ASS IS MINE, YOU PUNK-ASS PUNK!”
Instead, I fixed him with a good hard look and said, “Is it possible that while you were looking at the answer key, you changed your answers on your bubble sheet so that you’d have the correct answers to study from?” This is, of course, total bullshit. Nobody studies from the bubble sheet, for crissakes, you study from the exam booklet that has the questions and answers printed out on it. But, hey, I threw the kid a bone.
What’s this? he thinks, A lifeline? “Um. Yeah! Yeah, that must have been what happened.”
“And what were other questions that you wanted me to look at?” I asked sweetly.
“Uh, no, um, actually, that was the only that one,” he mumbled. Then he grabbed his bubble sheet and skedaddled.
What a punk-ass punk.
It’s a real pity, too, because he was one of the ones who sometimes hung around after class and asked questions, and seemed really interested.
