Abstract

The study used statistical procedures based on Item Response Theory to detect Differential Item Functioning (DIF) in polytomous tests. These were with a view to improving the quality of test items construction. The sample consisted of an intact class of 513 Part 3 undergraduate students who registered for the course EDU 304: Tests and Measurement at Sule Lamido University during 2017/2018 Second Semester. A self-developed polytomous research instrument was used to collect data. Data collected were analysed using Generalized Mantel Haenszel, Simultaneous Item Bias Test, and Logistic Discriminant Function Analysis. The results showed that there was no significant relationship between the proportions of test items that function differentially in the polytomous test when the different statistical methods are used. Further, the three parametric and non-parametric methods complement each other in their ability to detect DIF in the polytomous test format as all of them have capacity to detect DIF but perform differently. The study concluded that there was a high degree of correspondence between the three procedures in their ability to detect DIF in polytomous tests. It was recommended that test experts and developers should consider using procedure based on Item Response Theory in DIF detection.

Abstract

The study examined if schooling experience and teacher’s classroom interaction is the same for senior secondary school adolescent girls and boys in Jigawa state, Nigeria. It also determined whether influence of students’ perceived level of personalisation of the teacher’s classroom behaviour and environment exist on their participation in the classroom learning activities. These were with a view to improving the teacher-student’s relationships and teacher’s classroom effectiveness. The study adopted a survey design. The population consisted of all male and female students in public Senior Secondary Schools in Jigawa state. The sample consisted of 370 Senior Secondary Classes Three (SS III) students. Of this number, 185 were boys and 185 were girls selected through stratified sampling procedure using sex as stratum. Their average age was 15.17 years. A self-developed instrument was used to collect relevant data in the study. Data collected were analysed using Independent t-test statistical method. The results showed that teachers do not significantly interact with girls and boys in the same manner in the classroom. However, there existed a significant influence of students’ perceived level of personalisation of the teacher’s classroom behaviour on their participation in the classroom learning activities. Also, there was a significant influence of students’ perceived level of personalisation of the classroom environment on their participation in the classroom learning activities. It was concluded that schooling experience is not the same for girls and boys respectively. Thus, appropriate interventionist strategies should be put in place to assist realising the objective of equal educational opportunity.
