The purpose of this study was to develop a valid and reliable scale to identify the perception management tactics used by school administrators. For this purpose, a 42-item measurement tool, which was developed based on interviews with 6 School Principals, 11 Assistant Principals and 28 Teachers from different branches, was presented to eight…

Educational organizations in institutionalized environments may try to reflect a legitimate image of the environment in their internal structure. However, there may be loosely coupled relationship between anticipated legitimacy and the performed actions in the schools. Thus, that lack of congruence between rhetoric and the behaviors constitutes…

The purpose of the current study is to adapt "The Universal Science Literacy Scale" developed by Mun, Shin, Lee, Kim, Choi, Choi and Krajcik into Turkish. The study group of the current research is comprised of a total of 645 pre-service science teachers from 6 different universities of Turkey. In the first stage of the adaptation study,…

Although temporal issues affecting organizations and leaders have been researched, time orientation (preference for one or more of the present, past, and future time frames) and visioning ability of change agents within organizations remain open for additional investigation. This exploratory survey study compared self-reported time orientation…

Mathematical conjectures and theorems are most often of the form P(x) ? Q(x), meaning ?x,P(x) ? Q(x). The hidden quantifier ?x is crucial in understanding the implication as a statement with a truth value. Here P(x) and Q(x) alone are only predicates, without truth values, since they contain unquantified variables. But standard textbook…

We present a new tool for meta-analysis, "Meta-Essentials," which is free of charge and easy to use. In this paper, we introduce the tool and compare its features to other tools for meta-analysis. We also provide detailed information on the validation of the tool. Although free of charge and simple, "Meta-Essentials"…

Validity is one of the most debated constructs in our field; debates abound about what is legitimate and what is not, and the word continues to be used in ways that are explicitly disavowed by current practice guidelines. The resultant tensions have not been well characterized, yet their existence suggests that different uses may maintain some…

Based on data from a series of teaching experiments on standard tools of mathematical logic, this paper characterizes a range of student meanings for mathematical properties and logical connectives. Some observed meanings inhibited students' adoption of logical structure, while others greatly facilitated it. "Reasoning with predicates"…

This study describes the development and initial testing of the Multidimensional Cultural Humility Scale (MCHS), a counselor-report scale to measure a counselor's cultural humility, with a sample of 861 participants. Exploratory factor analysis, confirmatory factor analysis, and internal reliability coefficients revealed evidence for the…

High rates of depressive disorders are reported among young people on the autism spectrum. This condition is generally assessed using measures validated for typically developing young people. Tools adapted to children on the autism spectrum are not tailored to detect Major Depressive Disorder, nor have they been used among samples with an…

Objectives: The purpose of the study was to validate a measurement scale to assess self-perceived digital competencies of Mexican university students who have migrated from a mixed school-digital system to a fully digitalized educational environment because of COVID-19 confinement. The instrument was based on the European Union Digital Competence…

This article reports the development and validation of a test instrument to assess secondary school students' declarative quantum optics knowledge. With that, we respond to modern developments from physics education research: Numerous researchers propose quantum optics-based introductory courses in quantum physics, focusing on experiments with…

This study aimed to adapt the Selfitis Behavior Scale (SBS) to measure university students' selfitis behavior in Turkey. Within the scope of the study, the SBS was translated from English to Turkish. Data were collected in the validity and reliability studies from four study groups, including 343 university students. According to the confirmatory…

The academic buoyancy scale (ABS) is one of the most widely used instruments for measuring academic buoyancy. To obtain meaningful and valid comparisons across groups using ABS, however, measurement invariance should be ascertained a priori. To that end, we examined its measurement invariance, validity evidence based on relations to other…

This work reports a preliminary validation of the Peer Conflict Scale (PCS) for Portuguese young adults (ages 18-30 years). This instrument assesses aggression considering two of its forms (overt and relational aggression) and its two functions (reactive and proactive aggression). The initially proposed 4-factor model provided the best fit for our…
