Year: 2025
Type: article
Abstract: This study was focused on using item analysis indices for corroboration of critical thinking scale developed by Sunday, Dorathy in the year 2021; to determine the authenticity of the multiple choice items generated for university students global change, South-South Geo-Political zone Nigeria was the study area. Three research questions governed this study, and the study adopted an ex-post facto design; based on the secondary instrument on critical thinking scale. Multistage sampling procedure of three (3) stages; purposive, proportionate stratified and purposive were used to draw the sample of 1, 0 41 participants from the population. A reliability coefficient of 0.87 was gotten from the pilot study. The difficulty, discriminative and distractive indices were methods used to analyze the research questions. Based on the results; the item difficulty indices ranged from 0.71 to 0.27. While discriminating indices ranged from 0.61 to 0.15 and the distractive indices ranged from 0.89 to 0.32 respectively; for the fifty (50) items on SCTS. Conclusively, SCTS is authentic; because it has very good ranges of its difficulty, discriminative and distractive indices for university students in the globe. Recommendations were made that; evaluators or psychometricians should always find out the authenticities of developed instrument; especially, on item analysis indices to be sure of its goodness of the items. Other stake holders, such as; Tertiary institutions, WAEC; NECO and different measurement and evaluation bodies or departments in business areas; should regularly invite experts in measurement and evaluation disciplines to corroborate their instruments for positive changes in the globe
