This study aimed to develop a scale to measure teachers' digital assessment literacy self-efficacy. Teachers were selected from all regions of Turkey and different branches at primary, secondary, and high school levels to enhance generalization and diversity. The data was collected from 314 teachers for the exploratory factor analysis and 296 for…

Using the basic properties of the base-b representation of rational numbers, we will give an elementary proof of Gauss's lemma: "Every real root of a monic polynomial with integer coefficients is either an integer or irrational." The paper offers a new perspective in understanding the meaning of 'irrational numbers' from a deeper…

Despite continued research into the Community of Inquiry (CoI) framework, the best way to measure each presence of the framework, and in particular social presence, has not been effectively settled in prior research. The purpose of this study was to evaluate the validity of the social presence items in the CoI framework and its subscales, as well…

Purpose: The primary objective of this research paper was to examine the objectivity of the preselected items evaluation (PIE) method, a prevalent translation scoring method deployed by international institutions such as UAntwerpen, UGent and the University of Granada. Design/methodology/approach: This research critically analyzed the scientific…

This study aimed to develop and validate the Teacher Rating Scale of Leadership (TRSL) for assessing leadership in 3- to 6-year-old preschoolers. Developed through observation, interviews, and expert reviews, the TRSL was tested on 995 preschoolers in Zhejiang Province, China. It demonstrated high internal consistency (Cronbach's alpha…

We present a method to compute the power series expansions of e[superscript x] ln (1 + x), sin x, and cos x without relying on mathematical analysis. Using the properties of elementary functions, we determine the coefficients of each series through the method of undetermined coefficients. We have validated our formulae through the use of…

The Hearts and Flowers (H&F) task is a computerized executive functioning (EF) assessment that has been used to measure EF from early childhood to adulthood. It provides data on accuracy and reaction time (RT) across three different task blocks (hearts, flowers, and mixed). However, there is a lack of consensus in the field on how to score the…

Contribution: This article presents the development and validation of a novel instrument, the self-efficacy for engineering design (SEED) instrument, using a sample of 257 undergraduate students who studied engineering design (ED) in their mechanical engineering program of study. The SEED instrument consists of 35 self-report survey items…

The aim of this study is to examine the validity, reliability, and responsiveness of the Turkish version of the Adolescent Health Promotion-Short Form (AHP-SF). This cross-sectional study was completed with 1483 students. Confirmatory factor analysis (CFA) supported the construct validity of the scale, demonstrating a good model fit with…

This article presents a ten-item short scale for measuring digital competence. The scale is based on the Digital Competence Framework for Citizens, DigComp2.1 (Carretero et al., 2017). For our surveys, we used five items from the DigCompSat study (Clifford et al., 2020) and created five new ones to address the competence areas defined by…

Cheating attracts a significant amount of attention in conversations about assessment, and with good reason: if students cheat, we cannot be sure they have met the learning outcomes of their course. In this conceptual article we question the attention given to cheating as a concept and argue that the broader concept of validity is a more important…

Background: Schoolwide positive behavioral interventions and supports (PBIS) is an evidence-based framework for implementing a continuum of behavior support practices in schools to improve student outcomes. Research suggests that students with extensive support needs (ESN) may not have access to the complete continuum of behavioral supports within…

This article aims to reveal the adaptation and validation process of the Mentoring for Effective Mathematics Teaching (MEMT)--Mentee and --Mentor scales in the Turkish context, which was developed to examine preservice mathematics teachers' and mathematics mentor teachers' perceptions of mentoring practices within the Five-factor mentoring model.…

Background: Meta-analyses of educational interventions have consistently documented the importance of methodological factors related to the choice of outcome measures. In particular, when interventions are evaluated using measures developed by researchers involved with the intervention or its evaluation, the effect sizes tend to be larger than…

The purposes of the present study were a) to evaluate the construct validity of a questionnaire measuring parental physical activity (PA) orientation, and b) to examine the association between constructs of parental PA orientation and parental explicit PA modelling in parents of young children with disabilities. One hundred and thirty-five…
