This is interesting, though I must confess that I did not spend much time
on the mathematical proof showing that the logarithm of students'
confidence in the answer choice is better than the simple arithmetic sum.
Larry discussed using this at the Atlanta TBL workshop at the end of Sept,
and I must say I find the idea intriguing. I plan on using this next time I
teach a TBL course by simply assigining each MCQ the weight of the number
of answer choices and allowing students to distribute those points across
the different answer choices according to their confidence in the answers.
So if a MCQ contains 4 answer choices, students may assign all four points
to one answer if they are entirely sure that is the correct answer. If they
have no clue which answer is correct, I assume that they will assign one
point to each of the four answer choices.
The circulated paper seems to suggest that the logarithm of the student
assigned points to their answers better illustrates their degree of
certainty. Not sure I completely understand how that is so. Anyone on the
listserv willing to give a layman's explanation?
I hope everyone had, or is having, a great holiday break.
