A similar explanation might be the way one student answered the
question in the summer 2004 course when given the questions in printed form. This student
rewrote answer “d” before they chose it as “the portion of the Moon that is lit by the Sun that
we see.” As this student noticed, we worded answer “d” so that scientifically it is an incomplete
(it is interesting that a student would rewrite an answer so that they can choose it). Answer “e”
is the response we considered to be correct for this particular question, but “d” has correct
aspects to it, especially if other students understand it to mean what the student mentioned
above student wrote. We will be looking at both “d” and “e” as potentially correct responses in
the analysis section.
