| Abstract | Item bias is defined as the dependence of item responses and group membership conditional on the value of the trait that the test is supposed to measure. The results of item bias detection methods based on this conditional definition and using a stepwise or iterative procedure appear to be adequate. In this paper, experimental studies in the Netherlands on the explanation of item bias are reported. For each of the 60 items of an arithmetic test, an assessment was made as to whether the item was biased between Dutch and Turkish/Moroccan students at the end of their sixth-grade year. Hypotheses were formulated to explain the bias. According to the hypotheses, biased items were modified to become less biased and unbiased items were modified to become more biased. The original and modified test versions were randomly administered to each of 169 students of Dutch origin and 93 students of Turkish or Moroccan origin. The statistical tests showed that the hypothesis was confirmed in only three of the 38 cases. (Author/TJH) |
