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.…

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…

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…

Two novel proofs show that the sum of a specific pair of normal random variables is not normal are established in this note. This is one of the most often misunderstood facts by first-year students in probability theory and statistics. The first proof is concise using the moment generating function. The second proof checks whether the moments of…

Formative feedback is important in learning. Automating the provision of specific, objective, constructive feedback to large cohorts requires complex algorithms that most teachers do not have time to develop, suggesting that a community effort is needed to create a library of specialised algorithms. We present an exemplar algorithm for a class of…

The Anxiety Scale for Autism--Adults (ASA-A) captures the autistic anxiety experience, but we do not know whether it is structurally equivalent for men and women, or non-autistic people. Measurement invariance analysis considered gender and diagnostic status (342 cis-gender autistic men (N = 105) and women (N = 237), 316 cis-gender non-autistic…

In this article, we state an interesting geometric conservation property between the three angle bisectors of three similar right triangles and provide a proof without words for its justification. A GeoGebra applet is also presented to help with the understanding of the progression of the proof from inductive to deductive stage.

The objective of this study was to develop a measure that possesses both reliability and validity in order to evaluate innovative thinking within the realm of education. To achieve this, the instrument's validity and reliability were evaluated through quantitative methods in two distinct phases. A team of educational experts conducted the process…

This study aims to conduct the Turkish adaptation, validity, and reliability study of the Theory of Mind Inventory-2 (TOMI-2) developed by Hutchins and Prelock (2016) for 3-5-year-old children. The study group consists of 310 mothers with children in the 3-5 age group in Konya city center. Personal Information Form and Theory of Mind Inventory-2…

Purpose: The aim of this study was the development and validation (D&V) of an assessment tool to measure administrators' attitudes towards the 'Apprenticeship Embedded Degree Program (AEDP)' in higher education institutions (HEIs). Design/methodology/approach: A rigorous empirical method was followed encompassing four D&V phases:…
