Although school psychologists often comment on examinee motivation in their reports, systematic evaluation of effort is not common practice. Empirical assessment of performance effort provides critical evidence for the validity of evaluations and will likely lead to more valid assessments, recommendations, and placements. This article focuses on…

In this paper, a simple proof of the Morley's Trisector Theorem is presented which involves basic plane geometry only. The use of backward geometric approach, trigonometry or advanced mathematical techniques is not required. It is suitable for introducing to secondary or undergraduate students, as well as teachers or instructors for learning or…

The "k"-means clustering method, while widely embraced in college student typology research, is often misunderstood and misapplied. Many researchers regard "k"-means as a near-universal solution for uncovering homogeneous student groups, believing its success hinges primarily on the selection of an appropriate "k."…

In response to a call for research on using the SATs and ACTs for U.S.-based college and university admissions, researchers systematically interrogated the literature surrounding both tests, using a framework for validity evidence built upon the "Standards of Educational and Psychological Testing" and Kane's contemporary view of…

Fuzzy regression-discontinuity evaluations of college remediation often find negative and null estimates of local average treatments effects (LATEs), but with substantial heterogeneity. We find that a remedial quantitative skills course at Wellesley College has a modestly positive LATE on participation in mathematically intensive fields of…

In this study, an attempt was made to develop a valid and reliable measurement tool to determine teachers' self-efficacy levels for teaching metacognitive listening strategies. The study group consisted of 205 teachers for EFA and 248 teachers for CFA. As a result of the analyzes, a scale consisting of 16 items with 4 factors was developed. It was…

Research capability is one of the essential capabilities of scholars for effectively conducting their work. Yet current research lacks a structured exploration and measurement scale for Chinese scholars on this matter. In the Chinese research context, this study conducted two questionnaires based on the Research Self-Efficacy Scale (RSES) among…

The Perceptions of Inclusion Questionnaire (PIQ) assesses the perceptions of inclusion in 3rd to 9th grade students through three scales: social inclusion, emotional inclusion, and academic self-concept. This study aimed to establish the psychometric properties of the Spanish version of the instrument (PIQ-Spa) since no prior formal validation of…

Considering the crucial role of education in offering mitigation and adaptation strategies for climate change, there is a clear need for objective tools to assess its impact on the understanding of the issue among secondary school students. This paper describes the methodological design used to build and validate an instrument that explores…

The present paper aimed to develop and standardise a scale for assessing life skills in adults as per a ten-factor model given by World Health Organization (WHO), which was accomplished by revising a pre-existing 100-item life skills scale for adolescents. The objective was met in three consecutive studies. A revised 19-items life skills scale…

Background: Acceptance and Commitment Therapy (ACT) is a transdiagnostic approach which aims to increase psychological flexibility. Higher psychological flexibility has been associated with reduced psychological distress, mental health symptoms and improvements in well-being and functioning. Reviews of ACT for children and young people (CYP)…

The term "rigor" in education often evokes resistance due to its inconsistent definitions and widespread misconceptions. This study introduces and validates the RIGOR Walk framework, a research- and practitioner-informed tool designed to define, observe, and enhance rigorous learning environments across classrooms. The framework is…

While the term feedback engagement has become a buzzword in higher education, the constructs of feedback engagement have remained inadequately investigated, and research on the conceptualization and instrumentation of feedback engagement in the literature is limited. This paper presents the development and validation of a feedback engagement scale…

This study describes validity and reliability evidence of the Multidimensional Measure of Employability (MME) based on the internal structure and relations to other measures in a sample of unemployed persons in Portugal. Altogether, 216 individuals participated in an online survey. The MME's internal structure was tested by confirmatory factor…

An organizational climate based on research integrity is one of the key goals of contemporary universities and scientific organizations. Survey of Organizational Research Climate is widely tested and used instrument for measuring organizational climate based on research integrity developed in the USA; however, its successful use in different…
