我们比较了学生对四个多项选择力概念量表(FCI)问题的反应和对同等开放式问题的类似反应。我们的结果表明，两种格式的正确回答的百分比之间有很好的一致性，这表明FCI上的分心因素并不会对正确答案的数量产生负面影响。然而，相当大比例的开放式回答属于不包括在FCI多项选择中的类别。当这些替代类别作为干扰项以修订后的多项选择题的形式呈现给学生时，相当大比例的学生选择了这些替代反应。(C)2004年美国物理教师协会。
We have compared students' responses on four multiple-choice force concept inventory (FCI) questions with similar responses to equivalent open-ended questions. Our results indicate a good agreement between the percentages of correct responses in each of the two formats, indicating that distracters on the FCI do not adversely affect performance as measured by the number of correct answers. However, a significant percentage of the open-ended responses fall into categories that are not included in the FCI multiple choices. When these alternative categories were presented to the students as distracters in a revised multiple-choice format, a significant percentage of the students chose these alternative responses.
