IRT as Educational Solution in Testing for Building Resilient Future among Students in Delta State

The study investigated IRT as educational solution in testing for building resilient future among students in Delta State. Two research questions and two hypotheses guided the study at 0.05 of significance. The study adopted ex-post facto design. The sample of this study consistes of 600 (300 male and 300 female students) science students drawn from the 3 senatorial districts of Delta State. 2023 WASSCE physics paper 2 questions were used as instrument for data collection to demonstrate the items that differentially function through the item responses. The validity and reliability of the instrument was believed to be valid and reliable since WAEC is a standard examination body across selected English speaking West African Countries. The research questions were answered using L-R model while Independence Chi-square test was used to test the stated hypotheses using SPSS version 23 at 0.05 level of significance. The findings of the study indicated a high percentage of IRT DF in the 2023 WASSCE/SSCE physics multiple choice test response among male and female students, the study also indicated a high percentage of IR DF in the 2023 WASSCE/SSCE physics multiple choice test response among urban and rural students that can distort building of resilient future. In line with findings, it was recommended among others that Test should be constructed to accommodate same responses across groups to make the resilient future possible, test builders should delete and remove tests that are difficult and discriminate for the purpose of resilient society.
