The purpose of this study was to investigate further the effect of differential item performance by males and females on tests which have different item arrangements. The study allows for a more accurate evaluation of whether differential sensitivity to reinforcement strategies is a factor in performance discrepancies for males and females.…

Examined whether patterns of gender differential item functioning (DIF) in parcels of items are influenced by changes in item position. Findings for more than 2,000 college freshmen taking a test of mathematics suggest that the amounts of gender DIF and DIF present in item parcels tend not to be influenced by changes in item position. (SLD)

Differential test performance by undergraduate males and females enrolled in a developmental educational psychology course (n=167) was reported on a quantitative examination as a function of item arrangement. Males were expected to perform better than females on tests whose items arranged easy to hard. Plake and Ansorge (1982) speculated this may…

Effects of item arrangement, test anxiety, and sex on a mathematics test taken by motivated, upper-division undergraduates and beginning graduate students were investigated. Results showed that males outperformed females when items were arranged from easy to hard. (Author/GK)

Effects of item arrangement (easy-hard, uniform, and random), test anxiety, and sex on a 48-item multiple-choice mathematics test assembled from items of the American College Testing Program and taken by motivated upper level undergraduates and beginning graduate students were investigated. Four measures of anxiety were used: the Achievement Test…

What effect varying the phrasing of attitude statements would have across sex and grade was determined. Three content parallel forms were developed to assess student attitudes toward integration. Each form contained 15 items and differed only in terms of item phrasing either positive, negative or a combination of both. Six hundred and twenty-two,…

The relationship between differential item functioning (DIF)and test item context effects was studied in an investigation of whether the patterns of gender DIF in parcels of items are influenced by changes in item position, as seen in two forms of a test. A second aim was to determine whether performance of male and female test takers is…

Gender differences on the National Education Longitudinal Study of 1988 science tests were explored through statistical analyses and interviews with 25 high school students. Results show the importance of studying the validity of the outcome measure and suggest that conclusions about group differences and correlates of achievement depend on the…

Examined whether changes in format of mathematics items in the Third International Mathematics and Science Study (TIMSS) had any effect on gender differences in performance using a Swedish sample of 8,851 sixth, seventh, and eighth graders. Results show no significant changes in gender differences when item format is altered. (SLD)

Scores from mathematics (tested at 102 schools) and science (tested at 99 schools) sections of pilot forms of the Michigan High School Proficiency Test were examined for interaction between gender and response format (multiple choice or constructed response). Overall, neither males nor females seemed to be disadvantaged by item format. (SLD)

This digest introduces three issues to consider when evaluating test items for bias: fairness, bias, and stereotyping. In any bias investigation, the first step is to identify the subgroups of interest. Bias reviews and studies generally focus on differential performance for sex, ethnic, cultural, and religious groups. In preparing an item bias…

A procedure used to average several Mantel-Haenszel delta difference values for an item is described and evaluated. The differential item functioning (DIF) procedure used by the Educational Testing Service (ETS) is based on the Mantel-Haenszel statistical technique for studying matched groups. It is standard procedure at ETS to analyze test items…

A subtest of the Swedish Scholastic Aptitude Test dealing with interpretation of diagrams, tables, and maps (DTM) was studied to see whether the position or other characteristics of test items affected the noted gender differences in results. Results with 116,017 students show an effect of position on gender differences. (SLD)

This research summarizes differential item functioning (DIF) results for student produced response (SPR) items, a nonmultiple-choice mathematical item type in the Scholastic Aptitude Test I (SAT I). DIF data from 4 field trial pretest administrations (620 SPR items) and 10 final forms (100 SPR items with samples ranging from about 58,000 to over…

Whether the shaping of test items can itself result in qualitative differences in examinees' comprehension of reading passages was studied using the Pearson-Johnson item classification system. The specific practice studied incorporated, within an item stem line, references that point the examinee to a specific location within a reading passage.…
