Detecting Differential Item Functioning of Ordinary National Education Test Mathematics Subject in 2015 Academic year by Test Using MIMIC

Abstract

The objective of this research was to check Differential Item Functioning (DIF) by using Multiple Indicators and Multiple Causes (MIMIC) when distinguish genders, academic year 2015. Parameters that used in this research were 424,430 grade 12 students and samples were 500 grade 12 students by using multistage stage sampling. The research instrument was test of Ordinary National Education Test (O-NET) grade 12 students, academic year 2015, and Mathematics subject amount 32 items those were minor information.

This research found that 1)When distinguish students by genders revealed that male students had higher average score than female students. Male students had 9.89 average score, 4.75 standard diversion and female students had 9.37 average score, 4.75 standard diversion. 2) Parameter difficulty of Ability Parameters of Ordinary National Education Test (O-NET), Mathematics subject in 2015 academic year had the fewest difficulty .03 and the highest 5.95. Parameter of Discrimination the fewest was .13 and the highest was .73 3) Parameter of Ability Parameters of Ordinary National Education Test (O-NET), Mathematics subject in 2015 academic year had 500 students. The lowest Parameter of Ability Parameters was -1.45 and the highest was 3.60. 4) Analysis of Differential Item Functioning (DIF) of Ordinary National Education Test (O-NET), Mathematics subject by using Multiple Indicators and Multiple Causes (MIMIC) when distinguish by genders, academic year 2015. There were Differential Item Functioning (DIF) amount 8 items; items numbers 3, 6, 10, 15, 17, 18, 23, and 25. The test was partial male amount 8 items and there was not partial female.
