The accuracy of certain internal consistency estimators have been questioned in recent years. The present study tests the accuracy of six reliability estimators (Cronbach's alpha, omega, omega hierarchical, Revelle's omega, and greatest lower bound) in 140 simulated conditions of unidimensional continuous data with uncorrelated errors with varying…

The "Raven's 2 Progressive Matrices Clinical Edition" (Raven's 2; Raven, Rust, Chan, & Zhou, 2018), published by NCS Pearson, is an individually administered nonverbal assessment of general cognitive ability developed to measure "educative abilities," defined as the ability to think clearly and solve complex problems in…

For assessments that use different forms in different administrations, equating methods are applied to ensure comparability of scores over time. Ideally, a score scale is well maintained throughout the life of a testing program. In reality, instability of a score scale can result from a variety of causes, some are expected while others may be…

In response to the call for promoting three-dimensional science learning (NRC, 2012), researchers argue for developing assessment items that go beyond rote memorization tasks to ones that require deeper understanding and the use of reasoning that can improve science literacy. Such assessment items are usually performance-based constructed…

This study examined the degree that reliability coefficients for scores on the PTGI generalize across participant and study characteristics. Meta-analytic procedures resulted in observed and predicted mean alpha coefficients ranging from acceptable to excellent and appeared to be largely unrelated to the participant characteristics included in our…

Cohen's kappa coefficient was originally proposed for two raters only, and it later extended to an arbitrarily large number of raters to become what is known as Fleiss' generalized kappa. Fleiss' generalized kappa and its large-sample variance are still widely used by researchers and were implemented in several software packages, including, among…

This study explored the influence of different take-off thresholds on the reliability and magnitude of countermovement jump (CMJ) performance variables. Twenty-three men were tested on two separate sessions. CMJ performance variables were obtained against three external loads (0.5-30-60 kg) using three take-off thresholds: 10 N (arbitrary value of…

The objective of this study was to understand behavioral characteristics of creative physicists during their growth period, and we want to use any insight gained to help teachers and parents encourage students' creativity in their everyday life. To do this, the critical incident technique was utilized to extract behavioral traits from six…

Empirical researchers using qualitative comparative analysis (QCA) can work with crisp, multivalue, and fuzzy sets. The relative advantages of crisp and multivalue sets have been discussed in the QCA literature. There has been little reflection on the more frequent decision between crisp and fuzzy sets for which there often is no theoretical…

This study tested the psychometric properties of the "Sense of Belonging in STEM" Scale (SOB-STEM), a new scale measuring students' subjective evaluation of their academic and social experiences in STEM learning contexts, primarily focusing on purposeful interpersonal interactions. Data from 758 college students were analyzed, yielding…

To date, no measure of perceptions reflecting the view of childhood as a social construction exists within the fields of developmental psychology or education. The aim of this small-scale study was to develop items to assess beliefs about children along a spectrum -- at one end of the spectrum conceptualizing children as human "beings"…

This paper presents a unified Arabic version of the English action verbs mentioned in Bloom's taxonomy (1956) that has been checked for validity and reliability by a panel of education experts. Methodologically, the Bloom's list of action verbs was first translated into Arabic by an expert professor of translation. Then, using a mixed-method…

Civil engineering students in the United States rarely receive instruction about how their work affects social inequities. Indeed, research reveals that most engineering students lack critical consciousness and fail to recognize and analyze real social inequity challenges as they arise in engineering contexts. As history demonstrates, this can…

International large-scale assessments have gained much attention since the beginning of the twenty-first century, influencing education legislation in many countries. This includes Spain, where they have been used by successive governments to justify education policy change. Unfortunately, there was a problem with the PISA 2018 reading scores for…

Objective: The purpose of this study was to describe the relationship between community college department chairs and their adjunct faculty. Methods: This was a descriptive phenomenological qualitative study that used individual semi-structured interviews of 14 department chairs from a purposive sample drawn from a midwestern community college.…
