A procedure for the detection of differential item |
|
performance (DIP) is used to investigate the |
|
relationships between characteristics of mathematics |
|
achievement items and gender differences in performance. |
|
Eight randomly equivalent samples of high school seniors |
|
were each given a unique form of the ACT Assessment |
|
Mathematics Usage Test (ACTM). Students without requisite |
|
math courses were deleted from the samples to control the |
|
possible confounding effect of differences in instruction |
|
at the high school level. Based on the remaining |
|
students, signed measures of DIP were obtained for each |
|
item in the eight ACTM forms. These DIP estimates were |
|
then investigated in a six by eight (item category by |
|
firm) experimental design. Using analysis of variance |
|
(ANOVA) procedures, a significant item category effect |
|
was found indicating a relationship between item |
|
characteristics and gender-based DIP. Follow-up analyses |
|
suggested that geometry and mathematics reasoning items |
|
had the largest negative impact on female examinees and |
|
more algorithmic, computation-oriented items were |
|
relatively easier for females. (Author) |
