The gender DIF phenomena in a mathematics achievement test of sixth graders in Taiwan
The purpose of this study is to examine the genders DIF in a the sixth grademathematics achievement test based on instruction material of sixth grader.The Test items， presented in multiple-choice format， were prepared based on anedition of mathematics textbookspublished by the National Institute for Compilation and Translation. selected and edited from mathematical instruction material of sixth graders that was edited by government. The item format is multiple-choice format. 677Six hundred and seventy-seven students subjects were administered in an elementary school located in the TaipeiCounty participated in the study.ConQuest and EZDIF computer programs were applied in data analysis to conductdo DIF detection. The results are as follows: (1) girls’female's average score was significantly higher than of that of boys’males’；(2) items about the concepts of “sequence” and “place value relation” items were of bias and more difficult for girlsfemales；(3) DIF ore likely to occur easily occursin the gender subgroupsfor thosewhose scores areis close to original total mean of raw score，that was not purified；(4) DIF's occurrence seemedsto haves nothing to do with purified total score based on this research. Based on the above findings， tThe researchersalso provides suggestions for math teachers and future researchers.
