In this study, we seek to understand the beliefs that
chemistry
faculty hold when grading student solutions in problem solving situations.
We are particularly interested in examining whether a conflict exists
between the chemistry faculty beliefs and the score they assign to
students’ solutions. The three categorical values identified
in a similar physics education study were evident as themes in our
study: (i) a desire to see students’ explanation of their reasoning;
(ii) a reluctance to deduct points from a student’s answer
that might be correct; and (iii) projection of correct thought processes
onto a student solution, even when the student does not explicitly
show thought processes. The scoring of each student solution depended
significantly on the weight given to each theme by an instructor.
In situations where a participant expressed all the three themes,
the conflict was resolved by laying a burden of proof on either the
student or the instructor. In this study, a sizable minority of the
participating faculty acted inconsistently, in that they stated they
valued students showing their reasoning when solving problems, but
they graded student work in a way that would discourage students from
showing their reasoning.
