Wide agreement exists about the value and power of learning in social contexts, and social influences on learning have been studied from multiple perspectives. However, before this study, no known measure of the value of learning that happens in social spaces had been developed. This study introduces a scale to measure value created through…

In bilingual education, the integration of STE(A)M (Science, Technology, Engineering, Art, and Mathematics) with CLIL (Content and Language Integrated Learning) establishes a dynamic learning environment wherein students concurrently develop scientific, technical, linguistic, and creative competencies. These methodologies cultivate essential…

School leadership research literature has a large number of widely used constructs. Could fewer constructs bring more clarity? This study evaluates construct content validity, defined as the extent to which a measure's items reflect a theoretical content domain, in school leadership literature. To do so, we reviewed 29 articles that used Teaching…

In classical calculus textbooks, the existence of primitive functions of continuous functions is proved by using Riemann integrals. Recently, Patrik Lundström gave a proof via polynomials, based on the Weierstrass approximation theorem. In this note, it is shown that the proof will be easy by using continuous piecewise linear functions.

Executive function (EF) is frequently an area of vulnerability in conditions associated with intellectual disability, like Down syndrome (DS). However, current EF evaluation approaches are not designed for children with underlying neurodevelopmental conditions and may not demonstrate construct validity due to interpretational confounds. The…

Purpose: The purpose of this study was to evaluate the construct validity of three sentence-focused diversity measures, intransitive verb diversity, transitive verb diversity, and third person (3P) subject diversity, using two methods: (a) group differentiation of late-talking (LT) toddlers from peers with typically developing (TD) language and…

As artificial intelligence (AI) receives wider attention in education, examining teachers' acceptance of AI (TAAI) becomes essential. However, existing instruments measuring TAAI reported limited validity evidence and faced some design challenges, such as missing informed definitions of AI to participants. To fill this gap, this study developed…

The significance of teacher's assessment literacy (AL) was originally captured by the 1990 standards for teacher's competence in educational assessment. Competence in assessment has changed with the widespread use of recent technology advancements in educational assessment. Consequently, new measures are needed to measure Teacher Assessment…

A fascinating and catchy method for proving that a number of special lines concur is using the concept of locus. This is now the classical method for proving the concurrency of the internal angle bisectors and perpendicular side bisectors of a triangle. In this paper, we prove the concurrency of the altitudes and the medians by showing that they…

Across the US, schools struggle to recruit and retain teachers in rural communities. While the body of research that documents rural teacher staffing challenges is increasing, more research is needed about preservice teachers' decisions about where to teach and how their educator preparation programs (EPPs) may influence their decision. An…

Objective: The aim of the study was to develop the "Digital Amnesia Scale Adolescent Form-DAADF" to determine digital amnesia in adolescents aged 12-18 years and to examine its psychometric characteristics. Methods: In the study, 625 adolescents between the ages of 12-18 who use digital devices such as…

The purpose of this paper is to elaborate and comment on some themes related to construct validity, construct choice, and construct respecification in the Campbellian validity system. It is argued that Reichardt's [(2008, November). An alternative to the Campbellian conceptualization of validity. (Paper presentation). Evaluation 2008 Conference,…

The Strengths and Difficulties Questionnaire (SDQ) is a brief instrument developed primarily for screening children and adolescents for social-emotional learning. The SDQ contains four factors related to socio-emotional difficulties and one factor related to prosocial behaviour. However, studies of its factor structure have produced mixed results.…

This study aims to examine the psychometric properties of a scale developed to measure teachers' ability to use artificial intelligence tools in education. The scale was originally proposed as having 33 items across 5 sub-dimensions by Chat GPT-4, an AI system. To establish content validity, the scale form was submitted to expert review. An…

The present study explores the sources of validity evidence of the mathematics self-concept construct in Programme for International Student Assessment (PISA) 2022 with a focus on concurrent, discriminant, and predictive evidence. Mathematics self-concept was provided with a single index variable in PISA 2022. Using only the U.S. students who…
