Abstract:
|
In our previously reported
study we compared student performance on four FCI questions with
equivalent open-ended questions. Our results showed good agreement
between the percentage of correct responses on both the open-ended and
multiple-choice formats. However, some of the naturally arising
categories of the open-ended responses did not correspond to existing
FCI multiple choices, and some of the multiple-choice distracters on the
standard FCI questions were not effective. Hence, we decided to replace
the ineffective FCI distracters with choices constructed from the
incorrect open-ended categories. Here we compare student responses on
three equivalent multiple-choice formats for the same four FCI
questions: (1) With the usual distracters. (2) With some distracters
replaced with those constructed from the categories of the open-ended
responses described above. (3) With both the standard distracters as
well as those from the open-ended categories. We will also compare the
reasoning that students gave for their choices in each of the three
questionnaires. |
