The relationship between the difficulty and discrimination coefficients according to the two traditional measurement theories and the latent features of the items of the logical reasoning test among the sixth grade students.

Abstract

This study aimed to find the correlation between the factors of difficulty and Discrimination in the Classical Test theories and the Latent Trait Theory (Two-Parameter Logistic Model), and the researcher relied on the logical reasoning test prepared by the Assmentday Foundation, which is specialized in issuing various psychological tests in Britain in 2018. The researcher carried out the translation of the test instructions from English into Arabic because the paragraphs are forms, so he does not need to verify the validity of the translation because it crosses culture. The test was applied to a sample of (650) male and female students who were randomly selected from the sixth grade students. The statistical analysis of the items was carried out according to the two traditional measurement theories and the latent features, depending on the two-parameter model in analyzing the test items, as calculated by the Bilog-mg3 program, and no item was excluded from the test according to the two measurement theories. And discrimination according to the two measurement theories and it was found that the value of the correlation coefficient for the parameter of difficulty according to the two measurement theories (0.907) and the value of the correlation for the teacher of discrimination according to the two measurement theories (0.813), and all the correlation coefficients are positive and statistically significant at the level of significance (0.05). Some conclusions, recommendations and suggestions.
