The underrepresentation of students from low-income families and of culturally diverse students is a longstanding and pervasive problem in the field of gifted education. Teachers play an important role in equitably identifying and serving students in gifted education; therefore, the Having Opportunities Promotes Excellence (HOPE) Scale was used in…

Parent-teacher relationship (PTR) quality is linked to child and family-school functioning and may be especially important in the school adjustment of autistic children. However, measurement of PTR quality has been limited by inconsistency in the use of measures, a paucity of two-informant measurement, and limited psychometric consideration. We…

Purpose: This study introduces a framework to produce very short versions of the MacArthur-Bates Communicative Development Inventories (CDIs) by combining the Bayesian-inspired approach introduced by Mayor and Mani (2019) with an item response theory-based computerized adaptive testing that adapts to the ability of each child, in line with…

The authors evaluated measurement-level, factor-level, item-level, and scale-level revisions to the "Gifted Rating Scales-School Form" (GRS-S). Measurement-level considerations tested the extent to which treating the Likert-type scale rating as categorical or continuous produced different fit across unidimensional, correlated trait, and…

Validity and reliability are crucial when conducting research to ensure the truthfulness of an instrument. This study investigated the measurement functioning of an instrument on students' awareness of space science. The instrument was administered to 206 secondary school students involved in the Sudden Ionospheric Disturbance p outreach program.…

The currently available measures of online teaching effectiveness (OTE) have several flaws, including a lack of psychometric rigor, high costs, and reliance on the construct of traditional onthe-ground teaching effectiveness as opposed to the unique features of OTE (Blackman, Pedersen, March, Reyes-Fournier, & Cumella, 2019). Therefore, the…

Although environmental aesthetic has received considerable attention in recent years, there is a need for measuring and evaluating environmental aesthetic. With considering this gap in the literature, the purpose of this study is to develop the "Scale for Environmental Aesthetic Awareness" for university students and to compare students'…

The aim of this study is to propose advantages provided by computerized tools when assessing reading ability. A new computer-based reading assessment evaluating both word reading and reading comprehension processes was administered to 687 children in primary (N=400) and secondary (N=287) schools. Accuracy (weighted scores) and speed of access…

This study focused on the development of the Problem-Solving Team Effectiveness Scale, a measure used by practitioners to assess the professional learning of a problem-solving team (PST) engaging in the technical aspects of intervention selection, implementation, and evaluation. Several best practices by PSTs were initially identified through a…

Curriculum development has always been dealt as one of the most important areas of language learning and teaching by educational institutions. Null curriculum has been viewed as one of the significant kinds of curriculum types which is important due to its absence, being left out or overlooked but should not be disregarded. For this reason, a…

We present the development and validation of a new assessment tool, the Moon Phases Concept Inventory for Middle School (MPCI-MS), a concept inventory about the phases of the moon targeting students aged 10 to 14 years old. Items in the questionnaire are based on a careful examination of the concept domain of phases of the moon, ideas and concepts…

This study aimed to obtain a measurement tool in Turkish culture to determine the motivation of university students (pre-service teachers) toward STEM based on the expectancy-value theory. For this purpose, the validity and reliability studies of the Turkish version of the STEM Value-Expectancy Assessment Scale developed by Appianing and Van Eck…

Universities assess their academic learning environment to improve students' learning. Students' experience in e-learning environment is different from face-to-face educational environment. So, in this study a specific valid and reliable instrument was devised for assessing perception of e-students from educational environment, that is,…

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources including networks, servers, applications, and services. Our aim in this study was to develop and validate an instrument to investigate the determinants of cloud computing services (CCSs) based on Theory of…

The aim of this study was to carry out a preliminary validation of "Motivational Climate in Physical Education Scale" in Greek educational context and specifically in relation to elementary school students. The participants of the research were 184 (101 male and 83 female) students of grades 5th and 6th from four elementary schools, in…
