| Research Abstract |
In this study, we evaluated the validity of the Force Concept Inventory quantitatively, focusing on the false-answers. We addressed whether respondents who answer the questions of the FCI correctly actually have an understanding of the concepts of physics tested in the questions. To examine respondents' levels of understanding, we used subquestions that test them on concepts tested in the questions. Our sample size comprised totally 635 respondents; we derived false-positive ratios for prelearners and postlearners and then statistically test the difference between them. Then, we found that it is possible for postlearners to answer both questions without an understanding of the concepts of physics tested in the questions; therefore, Q.16 and Q.7 are invalid. However, this result does not indicate immediately that the two questions should be modified. We can use the questions if we can quantify the inadequacy of the questions and evaluate it as systematic errors.
