This study aims to compare the G and Phi coefficients as estimated by D studies for a measurement tool with the G and Phi coefficients obtained from real cases in which items of differing difficulty levels were added and also to determine the conditions under which the D studies estimated reliability coefficients closer to reality. The study group…

Although multiple-choice items (MCIs) are widely used for classroom assessment, designing MCIs with sufficient number of plausible distracters is very challenging for teachers. In this regard, previous empirical studies reveal that using three-option MCIs provides various advantages when compared to four-option MCIs due to less preparation and…

The purpose of the study was to construct and validate a Physics Aptitude Test (PAT) for senior secondary schools. The test was designed primarily as an assessment tool for senior secondary school students who have aptitude for Physics. Four research questions guided the study. It was an instrumentation study designed to produce an assessment tool…
