This explained confusion I've had for a long time about questions on multiple choice tests:
In the world of testing, she said, it does not really matter whether an answer is right or wrong; the “right” answer is the one that field testing has shown to be the consensus answer of the “smart” kids. “It’s a psychometric concept,” she said.
Even very intelligent children, she said, can sometimes overthink an answer and get it wrong.
Note, though, that there is no evidence in the article that Deborah Meier has any evidence for that claim (she has "lectured and written widely about testing", not "she has managed the testing process" for example). I find it slightly implausible that these actual passages and questions are field tested before they are used - that would be a major security headache - and I find it incredible that the question-writer doesn't state the right answer along with the question, instead leaving that to be determined by the consensus in field testing. However I have an idea what may be behind the claim.
When I set multiple choice exams (which don't have to be stupid like this one!) I am sent, along with the computer mark results, a detailed report on how students performed. For each question, I am shown some statistics, including what proportion of the students in each quartile
by overall mark got
this question right. If that distribution is flattish, this probably isn't a good question in terms of determining what students can do (e.g., if practically everybody got it right, maybe I should ask a harder question on that topic next year). If it slopes the wrong way, with the best students overall getting the "right" answer less often than students in lower quartiles, this is a huge red flag for me to look carefully at the question and the supposed right answer, as it strongly suggests that there may be an error.
I think someone may have mistaken "check that the right answer is the consensus of the smart kids" (if it isn't, look carefully to see what happened) for "define the right answer to be the consensus of the smart kids".
That said, while I will defend MCQ testing in some circumstances, I won't defend that particular test, which seems totally weird.
