Tests/exams (m.c. tests)

When a student takes a multiple-choice exam and doesn't recognize the
'correct' answer, he or she guesses, with a 1/4 or 1/5 "chance."  What is
the probability that he or she will repeat that choice at a later
time?   That they will _learn_ the errors they have made?  That they will
now "know" a bit of 'disinformation?'

Data from research on this specific issue will very likely show that there
is a _very_ high probability that students acquire a bundle of
misinformation this way!
