System thinking in an important area of study across STEM and non-STEM disciplines. The Earth system approach that drives the geosciences and is essential to issues of sustainability makes system thinking a critical skill in geoscience education. A key area in understanding the development of system thinking skills in the geosciences relies on the…

Purpose: This study aims to address the reliability and validity of the shortened versions of the Arabic dimensions of the learning organization questionnaire (DLOQ) to provide evidence on the learning organization (LO) concept in Lebanon and to draw attention to the applicability of the LO concept to facilitate the development and…

Reliability is usually estimated for a total score, but it can also be estimated for item scores. Item-score reliability can be useful to assess the repeatability of an individual item score in a group. Three methods to estimate item-score reliability are discussed, known as method MS, method [lambda][subscript 6], and method CA. The item-score…

A readily applicable procedure is discussed that allows evaluation of the discrepancy between the popular coefficient alpha and the reliability coefficient of a scale with second-order factorial structure that is frequently of relevance in empirical educational and psychological research. The approach is developed within the framework of the…

This article describes and reviews the "Test of Early Communication and Emerging Language" (TECEL; Huer & Miller, 2011). The test was constructed to assess infants' and toddlers' earliest communication and language abilities. The TECEL is a revision of the Nonspeech Test for Receptive/ Expressive Language (NST; Huer, 1983, 1988). The…

The engaging nature of video games has intrigued learning professionals attempting to capture and retain learners' attention. Designing learning interventions that not only capture the learner's attention, but also are designed around the natural cycle of attention will be vital for learning. This paper introduces the temporal attentive…

Cronbach's alpha is a statistic commonly quoted by authors to demonstrate that tests and scales that have been constructed or adopted for research projects are fit for purpose. Cronbach's alpha is regularly adopted in studies in science education: it was referred to in 69 different papers published in 4 leading science education journals in a…

Response to intervention (RtI) models have increasingly been adopted to improve outcomes for all students through the delivery of a continuum of supports and making timely responsive instructional decisions based on data. With this increasing popularity, researchers and practitioners have developed several RtI-related assessments, many of which…

This real-data-guided simulation study systematically evaluated the decision accuracy of complex decision rules combining multiple tests within different realistic curricula. Specifically, complex decision rules combining conjunctive aspects and compensatory aspects were evaluated. A conjunctive aspect requires a minimum level of performance,…

This study describes the development and initial testing of the Multidimensional Cultural Humility Scale (MCHS), a counselor-report scale to measure a counselor's cultural humility, with a sample of 861 participants. Exploratory factor analysis, confirmatory factor analysis, and internal reliability coefficients revealed evidence for the…

This study aimed to adapt the Selfitis Behavior Scale (SBS) to measure university students' selfitis behavior in Turkey. Within the scope of the study, the SBS was translated from English to Turkish. Data were collected in the validity and reliability studies from four study groups, including 343 university students. According to the confirmatory…

This study addressed the cross-cultural validation of the Chinese Motivation for Reading Questionnaire (CMRQ) in a sample of 522 seventh to ninth graders from two public schools in eastern China. Confirmatory factor analyses, item-total correlation analyses, and reliability analyses were conducted to assess the psychometric quality of the CMRQ.…

The purpose of this study was to develop a valid and reliable scale that can be used to identify the perceptions of teachers on their self-disclosure to their students in their interactions with them through social media. This study was designed as a sequential exploratory mixed method. So validity and reliability studies were conducted for this…

The aim of this study was to determine the validity and reliability of the Movement Environment Rating Scale (MOVERS), using data from 13 early childhood education and care (ECEC) settings. Test-retest reliability was calculated using ICCs, percentage agreement and weighted Kappa. Internal consistency was examined using Cronbach's alpha. To…

Background: Simulation-based learning can be used in university programmes to provide speech-language pathology students with essential clinical experiences. However, limited research has explored the use of simulation to support students' development of skills in clinical practice with people who stutter. Aims: (1) To evaluate students' clinical…
