Much research has been devoted to identification of differential item functioning (DIF), which occurs when the item responses for individuals from two groups differ after they are conditioned on the latent trait being measured by the scale. There has been less work examining differential step functioning (DSF), which is present for polytomous…

This three-article dissertation aims to address three methodological challenges to ensure comparability in educational research, including scale linking, test equating, and propensity score (PS) weighting. The first study intends to improve test scale comparability by evaluating the effect of six missing data handling approaches, including…

Item analysis is performed by developers as an integral part of the scale development process. Thus, items are excluded from the scale depending on the item analysis prior to the factor analysis. Existing item discrimination indices are calculated based on correlation, yet items with different response patterns are likely to have a similar item…

The Remote Associates Test (RAT; Mednick, 1962; Mednick & Mednick, 1967) is a commonly employed test of creative convergent thinking. The RAT is scored with a dichotomous scoring, scoring correct answers as 1 and all other answers as 0. Based on recent research into the information processing underlying RAT performance, we argued that the…

The effects of different response option orders on survey responses have been studied extensively. The typical research design involves examining the differences in response characteristics between conditions with the same item stems and response option orders that differ in valence--either incrementally arranged (e.g., strongly disagree to…

Differential item functioning (DIF) is often used to examine validity evidence of alternate form test accommodations. Unfortunately, traditional approaches for evaluating DIF are prone to selection bias. This article proposes a novel DIF framework that capitalizes on regression discontinuity design analysis to control for selection bias. A…

The research aimed at studying and comparing the futuristic thinking of Grade 9 students studying in schools of different sizes. The samples of the research were Grade 9 students of semester 2 in academic year 2020 in Sisaket Province, Thailand. The multi-stage random sampling technique was employed for the selection of 860 students from 12…

As researchers in the social sciences, we are often interested in studying not directly observable constructs through assessments and questionnaires. But even in a well-designed and well-implemented study, rapid-guessing behavior may occur. Under rapid-guessing behavior, a task is skimmed shortly but not read and engaged with in-depth. Hence, a…

The main goal of the current study is to develop a reliable instrument to measure programming anxiety in university students. A pool of 33 items based on extensive literature review and experts' opinions were created by researchers. The draft scale comprised three factors applied to 392 university students from two different universities in Turkey…

Identifying creatively gifted students remains a challenging yet important task. Often, teacher rating scales are used to assess students' creative behaviors; however, the school environment may not always provide opportunities for students to demonstrate creative ability, making it challenging for teachers to observe students' creative potential.…

Scientific reasoning competencies are relevant science competencies and therefore the development of assessment instruments for scientific reasoning competencies has become an integral part of science education research. However, some authors have questioned the validity of the instruments available so far, since their psychometric quality has not…

Objective: To determine the psychometric properties of the Montreal Cognitive Assessment (MoCA) in patients with a learning disability and examine it's utility for conducting mental capacity assessment. Method: This study was a cross-sectional, instrument validation study in an inpatient hospital setting, located in the East of England. The sample…

Student plagiarism is a growing problem within Australian universities and abroad. Potentially exacerbating this situation, research indicates that students' attitudes toward plagiarism are typically more permissive and lenient than the policies of their tertiary institutions. There has been suggestion that this is especially so in Asian countries…

The purpose of this study is developing a valid and reliable scale intended to determine the irrational beliefs of students in mathematics. The study was conducted with a study group consisting of 700 students in 2015-2016 academic year. Expert opinions were received for the content and face validity of the scale, and the Exploratory Factor…

In this study, we revised the "Metacognitive Awareness of Reading Strategies Inventory" (MARSI), a self-report instrument designed to assess students' awareness of reading strategies when reading school-related materials. We collected evidence of structural, generalizability, and external aspects of validity for the revised inventory…
