Gender related differential item functioning on basic general mathematics examination of Kano state college of education and preliminary studies, Kano, Nigeria


Hassan Ahmad Isma'il


Introduction: Testing has been accepted in our society as a method of decision making in formal places such as schools, recruitments, promotions, job placement, researches and guidance purposes. Therefore, quality of assessment instruments is essentials in determining the achievement of the students.

Purpose: The study aimed to determine effect size and direction of bias items in Basic General Mathematics Examination.

Methodology: An ex-post facto research design was employed to conduct the study and a sample of 665 NCE II students were purposively selected from KASCEPS. The data obtained were analysed using logistic regression and IRT based analysis.

Result: The findings of the study revealed that 2 items (16 - 17) were found to have magnitude level of DIF pattern in relation to gender and they all favoured female students. The study concluded that GSE Basic Mathematics examination developed by the College examination team is fair to be used for large population.

Recommendation: Based on the findings of this study its recommended that Basic General Mathematics examination items developers should improve their effort in selecting best items with appropriate words and or symbols so as to measure the target knowledge and skills under the study.  Basic general Mathematics test developers should ensure that sufficient and balanced content sampling is followed when developing GSE examination. This will go a long way in establishing better sampling and test-taking objectivity.
