Despite theoretical differences between item response theory (IRT) and classical test theory (CTT), there is a lack of empirical knowledge about how, and to what extent, the IRTand CTT-based item and person statistics behave differently. This study empirically examined the behaviors of the item and person statistics derived from these two measurement frameworks. The study focused on two issues:...

Assessment in teaching and learning allows both instructor students to evaluate the achievement, performance improve upon it. The achievement test appears as one of most commonly used assessment tools determine students' gains cognitive domain. study analysed science (SAT), a multiple-choice for grade 10 senior secondary school students. 50 SAT items were developed compliance with Malaysian cur...

topological analysis has been performed on the total electron density of the two forms of ozonemolecule,c2v and d3h ,to investigate the nature of chemical bonds ,molecular structure , atomiccharges and electrical properties. while these concepts have been completely discussed usingclassical models the emphasize in this work is based on quantum theory of atoms in molecules(qtaim). because the d3...

This study aims to analyze the item characteristics of mathematics problem-solving ability test instrument using Classical Test Theory model. The data collection was based on results documentation as many 359 students with dichotomous data. Qualitative validation analysis by experts uses panel method, and quantitative Aiken index Content Validity Ratio (CVR), while biserial point correlation. r...
