Evaluation of child-friendly school (CFS) policies is essential to determine the achievements of school efforts in reducing violence cases. This research aims to proving the reliability and validity of CFS policy evaluation instruments in elementary schools with different locations. This investigation uses the Context Input Process Product (CIPP)…

Interdisciplinary thinking is critical for equipping students to apply scientific knowledge and tackle societal challenges across various disciplines, which has been recognized as a key objective of twenty-first century science education. However, research on effective interdisciplinary assessment in secondary school science education is still…

Background: Cleft lip and palate (CLP) treatment in Norway is centralized and multidisciplinary, with long-term follow-up from birth to adulthood. The Norwegian Registry of Cleft Lip and Palate was established to ensure high-quality care and enable systematic data collection. Speech data are a key component, assessed by speech--language therapists…

The aim of this study was to verify the concurrent validity and the biological error-free reliability of a novel low-cost commercial encoder (Ergonauta I). Validity protocol involved comparisons with a custom system and other encoder commercially available (Vitruve). Reliability protocols involved interdevices and interunit comparisons. No…

An application of Bayesian factor analysis for evaluation of scale reliability is discussed, which is developed within the framework of latent variable modeling. The method permits direct point and interval estimation of the reliability coefficient of multiple-component measuring instruments using Bayesian inference. The approach allows also point…

A Bayesian statistics-based approach is discussed that can be used for direct evaluation of the popular Cronbach's coefficient alpha as an internal consistency index for multiple-component measuring instruments, as well as for testing its identity to scale reliability. The method represents an application of confirmatory factor analysis within the…

Purpose: The current literature on school teacher-created summative assessment lacks a clear consensus regarding its definition and key principles. The purpose of this research was therefore to arrive at a cohesive understanding of what constitutes effective summative assessment. Design/methodology/approach: Conducting a systematic literature…

When making inferences about the mental lives of others (e.g., others' preferences), it is critical to consider the extent to which the choices we observe are constrained. Prior research on the development of this tendency indicates a contradictory pattern: Children show remarkable sensitivity to constraints in traditional experimental paradigms,…

First-generation students (FGS) are a population that has received increasing attention, but the term "first-generation student" has been inconsistently defined. Such inconsistency creates challenges not only for research, but for students themselves, many of whom may find they meet the FGS definition in one institutional context, but…

In all research, ethical considerations are crucial to reliability and quality and researchers are guided by various national and international documents and ethical committees. Despite different strategies to guide researchers and to ensure quality, there still seems to be uncertainty in educational science about how research ethics should be…

Measuring classroom behavior among young children is important to guide assessment and intervention decisions, yet there is limited literature on appropriate direct observation tools for this purpose. This article describes the psychometric properties of the Behavior Assessment System for Children, Student Observation System (BASC-3 SOS) with 135…

The development of computational thinking skills is attracting attention worldwide. The use of visual or block-based coding in primary schools has gained momentum. Yet, students' acceptance of such coding environments has been neglected in the literature. This study presents a measurement instrument that will allow pursuing such an endeavor. The…

Purpose: Auditory training has been shown to reduce rater variability in perceptual voice assessment. Because rater variability is also a central issue in the auditory-perceptual assessment of dysarthria, this study sought to determine if training produces a meaningful change in rater reliability, criterion validity, and scaling magnitude of four…

The Creative Achievement Questionnaire (CAQ) is widely used to measure the creative achievement levels of individuals. Previous studies reported a varying range of reliability coefficients for the CAQ. To this date, no study has investigated the variability in the reliability coefficients of the CAQ. A random-effects reliability generalization…

The purpose of this instructional piece was to provide a nontechnical synthesis of common internal consistency reliability estimates used in professional counseling and in related fields. The article begins with an overview of coefficients alpha, omega, omega hierarchical, and H, with guidelines for their selection. Next, I provide recommendations…
