This paper aims to examine and assess the questions included in the "Turkish Common Exam" for sixth graders held in the first semester of 2018 which is one of the common exams carried out by The Measurement and Evaluation Centers, in terms of question structure, quality and taxonomic value. To this end, the test questions were examined…

Purpose: This study aimed to compare difficulty indices calculated for open-ended items in accordance with the classical test theory (CTT) and the Many-Facet Rasch Model (MFRM). Although theoretical differences between CTT and MFRM occupy much space in the literature, the number of studies empirically comparing the two theories is quite limited.…

The findings of previous research into the compatibility of stakeholders' perceptions with statistical estimations of item difficulty are not seemingly consistent. Furthermore, most research shows that teachers' estimation of item difficulty is not reliable since they tend to overestimate the difficulty of easy items and underestimate the…

Purpose: This study examined the quality of English test items using psychometric and linguistic characteristics among Grade Six pupils. Method: Contrary to the conventional approach of relying only on statistics when investigating item quality, this study adopted a mixed-method approach by employing psychometric analysis and cognitive interviews.…

The aim of this study was to develop, for the benefit of both test takers and test score users, enhanced "TOEFL ITP"® test score reports that go beyond the simple numerical scores that are currently reported. To do so, we applied traditional scale anchoring (proficiency scaling) to item difficulty data in order to develop performance…

Item response theory (IRT) has so many advantages than its precedent Classical Test Theory (CTT) such as non-changing item parameters, ability parameter estimations free from the items. However, in order to get these advantages, some assumptions should be met and they are; unidimensionality, normality and local independence. However, it is not…

The study aims to examine whether differential item function is displayed in three different test forms that have item orders of random and sequential versions (easy-to-hard and hard-to-easy), based on Classical Test Theory (CTT) and Item Response Theory (IRT) methods and bearing item difficulty levels in mind. In the correlational research, the…

Although medical curricula now adopt an integrated teaching approach, this is not adequately reflected in assessment of anatomy knowledge and skills. In this study, we aimed to explore the impact of the addition of clinical vignette to item stems on students' performance in anatomy practical examinations. In this study, 129 undergraduate medical…

This study evaluates the psychometric properties of three different forms of the Writing Apprehension Test (WAT; Daly & Miller, 1975) through Rasch analysis. For this purpose, the fit statistics and correlation coefficients, and the reliability, separation ratio, and chi-square values for the facets of item and person calculated for the…

Any meaningful initiative to improve the teaching and learning in introductory control systems courses needs a clear test of student conceptual understanding to determine the effectiveness of proposed methods and activities. The authors propose a control systems concept inventory. Development of the inventory was collaborative and iterative. The…

In information-rich environments, schools are often presented with a myriad of data from which decisions need to be made. The use of the information on a classroom level may be facilitated if performance could be described in terms of levels of proficiency or benchmarks. The aim of this article is to explore benchmarks using data from a monitoring…

Psychometric and utility studies on Social Emotional Assessment Measure (SEAM), an innovative tool for assessing and monitoring social-emotional and behavioral development in infants and toddlers with disabilities, were conducted. The Infant and Toddler SEAM intervals were the study focus, using mixed methods, including item response theory…

The present report demonstrates the difference between classical test theory (CTT) and item response theory (IRT) approach using an actual test data for chemistry junior high school students. The CTT and IRT were compared across two samples and two forms of test on their item difficulty, internal consistency, and measurement errors. The specific…

Presented in this symposium reader are nine papers, four of which deal with the theory and impact of the Rasch model on language testing and five of which discuss final examinations in secondary schools in both general and specific terms. The papers are: "Introduction to Rasch Measurement: Some Implications for Language Testing" (J. J.…
