Scale errors are intriguing phenomena in which a child tries to perform an object-specific action on a tiny object. Several viewpoints explaining the developmental mechanisms underlying scale errors exist; however, there is no unified account of how different factors interact and affect scale errors, and the statistical approaches used in the…

Scientific research is vital for student's education, fostering critical thinking, problem-solving skills, and deepening subject knowledge. To assess students' attitudes towards research, the attitude towards research scale was developed (EACIN). This study addresses three gaps regarding this instrument: inconsistent latent structure, lack of…

The patient health questionnaire-9 (PHQ-9) is widely utilized in assessing individuals' depression levels. Nevertheless, research regarding its factor structure and measurement invariance remains inadequate. The aim of this study was to delve into the factor structure of the PHQ-9 and to further investigate its measurement invariance across gender…

The present study aims to validate the Flourishing Scale (FS) in a convenience sample of 233 special education teachers. The FS's psychometric properties were investigated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA had a one-factor solution that explained 49.9% of the variance, a Cronbach's alpha internal…

Previous research has been limited regarding the measurement of computational thinking, particularly as a learning progression in K-12. This study proposes to apply a multidimensional item response theory (IRT) model to a newly developed measure of computational thinking utilizing both selected response and open-ended polytomous items to establish…

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved…

How parents value and address emotions with their children is essential for children's emotion socialization. This study developed and validated the short Parent-Child Emotion Communication questionnaire (PEC), which measures the extent to which parents appreciate emotions, consciously discuss their own and their child's emotions with their…

In response to the prevalence of perceived internship Pick-up Artist(PUA) behaviours and the lack of appropriate measurement tools, the purpose of this study was to develop and validate a new self-designed questionnaire, the Perceived Internship PUA Scale (PIPUAS), to assess college student interns' perceptions of internship PUA behaviours. The…

Academic Self-Efficacy for Self-Regulated Learning (ASE for SRL) represents individuals' belief in their abilities to regulate and organize their learning to achieve academic outcomes, and it is crucial for motivation and students' well-being. This study, conducted on a nationally representative sample of 26,564 10th grade Italian students (50.1%…

Background: Identifying as an engineer is essential for belonging and student success, yet the social context and professional norms make it more difficult for some students to establish an identity as an engineer. Purpose/Hypothesis: This study investigated whether first-generation college students' funds of knowledge supported their engineering…

Despite ongoing global efforts to combat discrimination, hate speech is a growing problem in many countries. Hate speech is also widespread among young people and thus also affects schools. Because of the negative consequences of hate speech for the targeted individuals and for society in general, schools and teachers are generally encouraged to…

Research-based assessments (RBAs) allow researchers and practitioners to compare student performance across different contexts and institutions. In recent years, research attention has focused on the student populations these RBAs were initially developed with because much of that research was done with "samples of convenience" that were…

This study examined the interconnections between perceived teacher support, student selfregulation, and psychological well-being among undergraduate English majors in Iran (n = 347). Confirmatory factor analysis (CFA) validated the measurement model, demonstrating sound internal consistency as well as convergent and discriminant validity. Harman's…

The Digital Stress Scale (DSS) is used to measure digital stress, which is the perceived stress and anxiety associated with social media use. In this study, the Chinese version of the DSS was validated using a sample of 721 Chinese college students, 321 males and 400 females (KMO = 0.923; Bartlett = 5,058.492, p < 0.001). Confirmatory factor…

The Expectancy-Value model has been extensively used to understand students' achievement motivation. However, recent studies propose the inclusion of cost as a separate construct from values, leading to the development of the Expectancy-Value-Cost model. This study aimed to adapt Kosovich et al.'s ("The Journal of Early Adolescence", 35,…
