Among all, Cronbach's Alpha and McDonald's Omega are commonly used for reliability estimations. The alpha uses inter-item correlations while omega is based on a factor analysis result. This study uses simulated ordinal data sets to test whether the alpha and omega produce different estimates. Their performances were compared according to the…

While there has been a lot of debate over the impact of online and remote learning on mental health and well-being, there has been no systematic syntheses or reviews of the research on this particular issue. In this paper, we review the research on the relationship between mental health/well-being and online or remote learning. Our review shows…

Traditional Chinese medicine (TCM) is an important component of China's medical system. How to educate TCM practitioners in China, therefore, has become a crucial issue. To contribute to this issue, the current research identified the competency model of TCM practitioners in China and developed an evaluation for TCM students. We combined Bloom's…

Recently, interest in test subscore reporting for diagnosis purposes has been growing rapidly. The two simulation studies here examined factors (sample size, number of subscales, correlation between subscales, and three factors affecting subscore reliability: number of items per subscale, item parameter distribution, and data generating model)…

The need to incorporate active learning (AL) in higher education has become a prominent issue discussed by major leadership organizations such as the Conference Board of Mathematical Sciences (CBMS, 2016). These calls for AL are based on a large and growing body of research documenting the correlation between AL use and reduced failure rates,…

The aim of this study is to determine whether the Happiness Fear Scale (FHS) developed by Joshanloo and Weijers (2014) is suitable for Turkish culture. For this purpose, validity and reliability of the scale were examined. The study consisted of 180 university students, 87 male and 23 female. The linguistic equivalence of the scale was made by…

The basis of this study is Kelley's (1992) two-dimensional model, which measures five follower types. Previous investigations did not support the validity of Kelley's model. Although the model is utilized in research, the validity and reliability of the Kelley Followership Questionnaire (KFQ) is still in question. In this study, the KFQ validity…

Constituting a metacognitive strategy, system competence or systems thinking can only assume its assigned key function as a basic concept for the school subject of geography in Germany after a theoretical and empirical foundation has been established. A measurement instrument is required which is suitable both for supporting students and for the…

Researchers in higher education frequently evaluate institutional effectiveness as the difference between an actual and predicted graduation rate, but little is known about whether such a method is reliable or valid. This study examines the measurement properties of effectiveness scores derived from regression residuals for community colleges in…

Undergraduate grade point average (GPA) is a commonly employed measure in educational research, serving as a criterion or as a predictor depending on the research question. Over the decades, researchers have used a variety of reliability coefficients to estimate the reliability of undergraduate GPA, which suggests that there has been no consensus…

The Cognitive Style Indicator (CoSI) includes 3 cognitive dimensions: creating (flexible, open-ended and inventive), knowing (emphasizing facts, details, objectivity, and rationality), and planning (guided by preferences for certainty and well-structured information). The first aim of this research was to validate the 3-factor structure of the…

Validity and reliability of Turkish form of sport brand personality scale, which was developed by Mitsis and Leckie (2016), was presented in this study. Scale was designed to reflect the impact of individuals' favorite athletes on them in other words the strength of the role model factor. In study, participants were tried to reach through an…

The Scylla and Charybdis in this discussion of teacher evaluation are standardized achievement test data on the one hand, and classroom observational systems on the other. These are the two most common methods used to judge teachers' competency. Both have serious flaws: the former primarily with validity, the latter primarily with reliability. At…

In line with 'the entrepreneurial university' discourse, managerialism and performative culture brought new expectations to faculty such as developing online programmes/courses, carrying out training for professionals, obtaining research funds, leading projects in cooperation with industry/business, collaborating with colleagues from various…

The purpose of this research is to first estimate the item and ability parameters and the standard error values related to those parameters obtained from Unidimensional Item Response Theory (UIRT), bifactor (BIF) and Testlet Response Theory models (TRT) in the tests including testlets, when the number of testlets, number of independent items, and…
