Although equality of opportunity in education is a current and important issue, most of the studies on this subject are based on theoretical studies rather than empirical studies. The main reason for this can be said to be the lack of a valid and reliable measurement tool in this field. For this reason, this study aims to develop a valid and…

Self-report measures are essential sources of information about learners' studying perceptions. These perceptions also guide self-regulated learning (SRL) decisions and strategies in future studying. However, the development of self-report methods has not kept pace with other multi-modal methodological advancements, particularly in the field of…

Background: This paper presents a description of the development and psychometric properties of a self-report instrument for the assessment of sexual behaviour and concerns of people with mild intellectual disabilities (SEBECOMID-S). Methods and procedures: The study included 281 people with mild intellectual disabilities. The psychometric…

Background: The objective of this systematic review is to identify characteristics, trends, and gaps in measurement in Science, Technology, Engineering, and Mathematics (STEM) education research. Methods: We searched across several peer-reviewed sources, including a book, similar systematic reviews, conference proceedings, one online repository,…

Measurement invariance (MI) is required for validly comparing latent constructs measured by multiple ordinal self-report items. Non-invariances may occur when disregarding (group differences in) an acquiescence response style (ARS; an agreeing tendency regardless of item content). If non-invariance results solely from neglecting ARS, one should…

Background: Assessment of work performance (AWP) is a test for assessing work performance and can be utilised in matching person-work and applying effective interventions. It was aimed to adjust and to evaluate the validity and reliability of AWP in Turkish with individuals with mild intellectual disability (ID). Methods: The study was conducted…

The present article describes the development and validation of the Informational and Normative Conformity Scale (SKI-N), a brief self-report tool capturing adolescents' general propensity to adopt a conformist attitude, and the underlying motives for doing so. The presentation includes a description of scale construction and an assessment of the…

The purpose of this study was to adapt the Self Description Questionnaire for Preschoolers into Turkish and to examine the self-concept of Turkish preschoolers based on sex and age. A total of 420 preschoolers participated in the study. The viability of the six-factor solution for the Turkish sample was examined using the first- and second-order…

Assessing the measurement model (MM) of self-report scales is crucial to obtain valid measurements of individuals' latent psychological constructs. This entails evaluating the number of measured constructs and determining which construct is measured by which item. Exploratory factor analysis (EFA) is the most-used method to evaluate these…

Effective leadership is essential in transforming schools into vibrant learning environments that foster teachers' professional growth and boost student achievement. Among various leadership styles, transformational leadership, with its emphasis on vision, support, and innovation, stands out due to its potential to maximize performance and foster…

Research Findings: This study provides psychometric validation of the Classroom Engagement Scale (CES), a 14-item, teacher-report, formative assessment of behavioral engagement. It is currently used for all kindergarten children in a large, urban school district where it is embedded in the report card. Multi-level factor analysis revealed two…

Childhood social and emotional competencies are recognized as teachable skills affecting well-being and developmental outcomes across the life span. This study sought to develop and validate a brief self-report measure of social-emotional competencies in middle childhood. The study used items from the 2015 Middle Childhood Survey, administered to…

The Evaluating the Quality of Instruction in Post-secondary Mathematics (EQIPM) is a 14-item instrument that uses videos of teaching to investigate the quality of instruction in college algebra courses taught at community colleges. We hypothesize that quality of instruction can be characterized along three distinct factors, the interactions…

This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

Creativity is highly valued in both education and the workforce, but assessing and developing creativity can be difficult without psychometrically robust and affordable tools. The open-ended nature of creativity assessments has made them difficult to score, expensive, often imprecise, and therefore impractical for school- or district-wide use. To…
