Guessing in Multiple Choice Questions: Challenges and Strategies

Introduction: Guessing is one of the most challenging issues in multiple choice questions. Several strategies, such as negative scoring, have been suggested for preventing students from choosing the right answer just by chance. However, there is no general agreement on using such strategies. The aim of this study was to review the scoring methods which are used for reducing guessing, and evalua...

What Can Be Approximated by Polynomials with Integer Coefficients

Can billiard eigenstates be approximated by superpositions of plane waves ?

The plane wave decomposition method (PWDM) is one of the most popular strategies for numerical solution of the quantum billiard problem. The method is based on the assumption that each eigenstate in a billiard can be approximated by a superposition of plane waves at a given energy. By the classical results on the theory of differential operators this can indeed be justified for billiards in con...

Analysis of Multiple Choice Questions Based On Classical Test Theory

Introduction: The aim of this study was to use Classical Test Theory (CTT) software for qualitative and quantitative analysis of Multiple Choice Questions (MCQ) for Master students of health discipline. Methods: This study was carried out on two groups each including 50 undergraduate students of public health, and two groups of 50 and 26 undergraduate students of occupational health. The final...
