Information literacy is a fundamental component in the academic development of future professionals. The aim of the study was to evaluate the metric properties of the 'questionnaire of self-perceived information competences', analyzing the factorial structure, internal consistency, convergent validity, factorial invariance according to gender and…

This study aimed to validate a modified Statistics Anxiety Scale for students in the United States taking university courses. Modifications were made by changing the wording of several items to be consistent with American English, and to accommodate students taking statistics courses in various formats. Items were added to investigate anxiety…

The Fundamental Concepts for Organic Reaction Mechanisms Inventory (FC-ORMI) is a concept inventory with most items in a two-tier design in which an answer tier is followed by a reasoning tier. Statistical results provided strong evidence for the validity and reliability of the data obtained using the FC-ORMI. In this study, differential item…

Test fairness is critical to the validity of group comparisons involving gender, ethnicities, culture, or treatment conditions. Detection of differential item functioning (DIF) is one component of efforts to ensure test fairness. The current study compared four treatments for items that have been identified as showing DIF: deleting, ignoring,…

More than a decade after two comprehensive examinations of the technical properties of the ClassMaps Survey (CMS), this study reexamined the structure and internal consistency of the scale and, for the first time, examined its measurement invariance across gender and school levels. Participants were 1,083 elementary and middle level students from…

Consequential validity (often referred to as "test fairness" in practice) is an essential aspect of educational measurement. This study evaluated the consequential validity of the Research-Based Early Mathematics Assessment (REMA). A sample of 627 children from PreK to second grade was collected using the short form of the REMA. We…

Background: Technically sound measures are necessary for accurately identifying youth at risk for depression, but many studies rely on classical test theory metrics or adult samples to evaluate measures. This study examined the use of the PHQ-8, a common and freely available pediatric depression screener, in an adolescent sample using item…

Large-scale standardized tests are regularly used to measure student achievement overall and for student subgroups. These uses assume tests provide comparable measures of outcomes across student subgroups, but prior research suggests score comparisons across gender groups may be complicated by the type of test items used. This paper presents…

Digital literacy is essential for scientific literacy in a digital world. Although the NGSS Practices include many activities that require digital literacy, most studies have examined digital literacy from a generic perspective rather than a curricular context. This study aimed to develop a self-report tool to measure elements of digital literacy…

This research aimed to investigate animation-based achievement tests according to the item format, psychometric features, students' performance, and gender. The study sample consisted of 52 fifth-grade students in Samsun/Turkey in 2017-2018. Measures of the research were open-ended (OE), animation-based open-ended (AOE), multiple-choice (MC), and…

Validity of a measurement refers to appropriate test score meanings, uses, and interpretations (Messick, 1989; Kane, 1992). There are different approaches to validity: an evidentiary aspect of validity is one requiring gathering statistical evidence to evaluate test score meaning. A common approach to validation is comparisons of test score equity…

The purpose of this study is to construct a digital culture test in light of the Item Response Theory and to investigate its psychometric properties. The study sample consisted of six hundred fifty (650) male and female students in the eighth grade from the Directorate of Education and Teaching of Salt District. To obtain the results, the…

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were…

The Bruininks-Oseretsky Test of Motor Proficiency -- Second Edition (BOT-2) is a commonly used assessment of children's skills. It is important that assessments have validity evidence reported about them. The objective of the study was to investigate the structural validity of the BOT-2's eight subscales and four composite scales. A sample of 117…

This study investigated the psychometric properties of the Early Numeracy Screener. The Early Numeracy Screener is a teacher-administered, paper-and-pencil test measuring counting skills, numerical relational skills, and basic arithmetic skills. Three hundred and sixty-six first graders took the Early Numeracy Screener at the beginning of the…
