From the perspective of positive psychology, the study and measurement of subjective well-being has popularized a growing interest towards variables such as affective perception. In an attempt to explain and evaluate the affective structure in positive terms (PA) and negative terms (NA), PANASN affect scale (Sandín, 2003) constitutes the version…

Following COVID-19, the global educational landscape shifted dramatically. Almost every educational institute in Bangladesh undertook a strategic move to begin offering online or blended learning courses to mitigate the challenges created by the pandemic. The TVET sector, particularly the polytechnic institute of Bangladesh, endeavored to explore…

The Kaufman Domains of Creativity Scale (K-DOCS) is a self-reported rating scale that measures creative behaviors in five areas. Despite the vast amount of research on the scale, the internal consistency reliability of K-DOCS scores have not been examined. Specifically, there is no study on the overall reliability coefficients, the variation in…

The reason for conducting the present case study was the problems the researchers encountered during data collection for another research project (Primary Study) entitled "The effects of virtual versus traditional flipped classes on EFL learners' grammar knowledge, self-regulation, and autonomy." Two online questionnaires were…

Purpose: The aims of this study were to classify, identify and follow-up young swimmers' performance and its biomechanical determinants during two competitive seasons (in seven different moments of assessment--M), and analyze the individual variations of each swimmer. Method: Thirty young swimmers (14 boys: 12.70 ± 0.63 years-old; 16 girls:…

Estimation of parameters for the many-facets Rasch model requires that conditional on the values of the facets, such as person ability, item difficulty, and rater severity, the observed responses within each facet are independent. This requirement has often been discussed for the Rasch models and 2PL and 3PL models, but it becomes more complex…

Recent research suggests that the fit between a digital textbook and the learning tasks students perform with the textbook has a significant role in determining the outcomes of usage. An empirical assessment was performed on the impacts of six antecedents on perceived fit and impacts of perceived fit on utilization, satisfaction, and perceived…

Decision consistency (DC) is the reliability of a classification decision based on a test score. In professional credentialing, the decision is often a high-stakes pass/fail decision. The current methods for estimating DC are computationally complex. The purpose of this research is to provide a computationally and conceptually simple method for…

Science knowledge is reflected in mental models that students tend to form when dealing with science phenomena. One way to identify students' mental models about scientific concepts is the use of diagnostic tests (inventories). Even though several statistical approaches and tools intended for the analysis of such inventories' results exist in the…

The relationship between conscientiousness and creativity remains equivocal. This is surprising because conscientiousness is a good predictor of job performance across most criteria and occupations. In this longitudinal study, I found support for the achievement striving and the dependability aspects of conscientiousness affecting team member…

Purpose: Ultrasound imaging offers a noninvasive adjunct to clinical swallowing assessment. Published reliability of sophisticated ultrasound systems is promising; however, no data exist for reliability using more affordable, pocket-sized devices. This study explored intrarater, interrater, and test-retest reliability of swallowing measures…

Phenomenography is an empirical approach to ascertain the qualitatively different ways in which individuals experience and understand aspects of the world around them. Originating in educational research (Marton, F., & Säljö, R. (1976). On qualitative differences in learning. 1- outcome and process. "British Journal of Educational…

Do adolescents remember imaginary companions (ICs) from early childhood? Researchers interviewed 46 adolescent participants in a prospective longitudinal study about their ICs from early childhood (age 5 1/2). The existence of one or more ICs was documented in early childhood for 48% of children (G. Trionfi & E. Reese, 2009). At age 16, most…

Research self-efficacy is a key component of college students' career development. This study's purpose was to develop and begin to construct a validity argument for scores from the Sources of Research Self-Efficacy (SRSE) scale in college students. We explored validity evidence for SRSE scores from 719 undergraduate and graduate students based on…

The term "nei juan" (in English "involution") has become a buzzword in recent Chinese tertiary educational contexts, denoting the intense competition and anxiety among Chinese college students. This project aims to develop a reliable and valid scale measuring Chinese college students' competitive psychology, that is, an…
