Using a newly created teacher evaluation instrument, Inter-rater Reliability (IRR) analyses were conducted on four teacher videos as a means to establish instrument reliability. Raters included 42 principals and assistant principals in a southern US school district. The videos used spanned the teacher quality spectrum and the IRR findings across…

This study attempted to create a valid and reliable instrument to measure how gifted children perceive the gifted label and others' perceptions of giftedness. We recruited a total of 300 gifted Turkish children (59.3% males; 40.7% females) aged 10-13 years (M = 11.4, SD = 0.99) to this validity and reliability study. For validity concerns, we…

Video data analysis (VDA) represents an important methodological framework for contemporary research approaches to the myriad of footage available from cameras, devices, and phones. Footage from police body-worn cameras (BWCs) is anticipated to be a widely available platform for social science researchers to scrutinize the interactions between…

Single-case design is a research methodology that entails repeated measurement to assess the influence of an independent variable on a dependent variable over time. Data collected in this manner are regularly analyzed using visual analysis of data displayed in a linear graph. Although there is agreement regarding critical elements of visual…

One-hundred and twenty-two undergraduates completed a survey assessing beliefs that WM is a stable trait, or that it is quality that can be improved with skill training. They then read an authentic set of journal articles in a special issue, which discussed whether a program called CogMed is or is not effective in promoting WM functioning.…

Mobile technologies, including apps, have become increasingly popular, and are being used to support daily activities among a variety of individuals. While the use of mobile technologies will not eliminate barriers often faced by individuals with disabilities, these systems have the potential to help minimize some of these barriers. As the…

This article outlines a readily applicable procedure for point and interval estimation of the population discrepancy between reliability and the popular Cronbach's coefficient alpha for unidimensional multi-component measuring instruments with uncorrelated errors, which are widely used in behavioral and social research. The method is developed…

There is a vast body of literature documenting the positive impacts that rater training and calibration sessions have on inter-rater reliability as research indicates several factors including frequency and timing play crucial roles towards ensuring inter-rater reliability. Additionally, increasing amounts research indicate possible links in…

This dissertation measures the multicultural teaching competency (MTC) and the frequency at which science educators use culturally relevant educational practices (CREPs). This study's mixed-method, convergent design is grounded in critical theory, and the MTC and culturally relevant education (CRE) framework. Findings suggest that the CREPs-F…

Background: The prevalence of dementia is increasing, bringing a range of challenges, such as eating, drinking and swallowing (EDS) difficulties, that are associated with aspiration, which can be fatal. Early identification of EDS difficulty in early-stage dementia could prevent complications, but reliable indicators are needed to help develop…

Nonacademic staff in higher education, also known as support staff, is a necessary and under-researched workforce essential for the success of higher education institutions. The higher education needs emphasized by the COVID-19 pandemic, state budget cuts, and increasing levels of turnover from the nonacademic population highlight the need for a…

The article presents the development and validation of a new measurement tool, the scale of Jealousy in romantic relationship (JRRS), designed to assess romantic jealousy in individuals aged 18 and above with or without a romantic relationship. The scale was developed through a literature review and tailored to the Turkish culture. The exploratory…

Students who are engaged writers are likely to produce better writing and to enjoy writing more than students who are disengaged writers. Yet, we are unaware of any existing tool that validly and reliably measures writing engagement. In this article, we describe what writing engagement is and why it is important. Then, we present the Writing…

The consistency of psychometric properties across waves of data collection provides valuable evidence that scores can be interpreted consistently. Evidence supporting the consistency of psychometric properties can come from using a longitudinal extension of item factor analysis to account for the lack of independence of observation when evaluating…

Setting cutoff scores is one of the most common practices when using scales to aid in classification purposes. This process is usually done univariately where each optimal cutoff value is decided sequentially, subscale by subscale. While it is widely known that this process necessarily reduces the probability of "passing" such a test,…
