Whether there is a gender-by-item interaction that makes easy mathematics test items easier for females than for males and difficult items harder for females than for males was tested in two studies, involving 10,321 eighth graders and 5332 ninth graders and results from nine mathematics tests. The hypothesis was generally supported, as discussed.…

This study used a diagnostic testing approach to compare the mathematics achievement of eighth-grade students across a sample of 20 countries, analyzing data from the Third International Math and Science Study-Revised (TIMSS-R, 1999). Using the rule-space method, student mastery was measured on 23 specific content knowledge and processing…

Item responses of 2,380 mathematically talented junior high school students (1,437 males and 943 females) were studied to determine gender differences, using the mathematical sections of the Scholastic Aptitude Test (SAT-M). Girls excelled on miscellaneous items and data sufficiency items but performed less well on algebra items than boys. (SLD)
