| Outline of Final Research Achievements |
In this study, we quantified the validity of FCI as a systematic error and analyzed its behavior. We focused on the false positives and used subquestions to judge whether a student understands the concept tested in an FCI question. The questions for which we created the subquestions are limited to the three invalid-like questions that, according to prior research, elicit false positives from students, and one of the remaining 27 valid-like questions. We used the results of the valid-like question and its subquestions to estimate the systematic error arising from the remaining 26 valid-like questions. Our results indicate that true score can be lower than half of raw score and true average normalized gain can be as low as half of raw average normalized gain, depending on the fitting function for the estimation. We also found that there are thresholds in the relationship between true positive ratio and raw score for the invalid-like questions, but not for the valid-like question.
