Visual inspection of luggage using X-ray technology at airports is a time-sensitive task that is often supported by automated systems to increase performance and reduce workload. The present study evaluated how time pressure and automation support influence visual search behavior and performance in a simulated luggage screening task. Moreover, we…

The study was designed as a linked two-phase investigation, aiming to psychometrically develop and validate a Chinese version of the "Organizational Climate Diagnostic Instrument for Junior High Schools" (OCDI-JH) for use in Taiwan. Through extensive literature reviews, the complex phenomena of school climate were decomposed into a…

This study aims to discover the effectiveness of the blended learning model in mathematics learning to improve the achievement of mathematical concepts. This study employed a quasi-experimental design with a non-equivalent control group. The experimental class was taught through blended learning, while the control class was taught through the…

In this study, we outlined some of the obstacles associated with screening and identifying high-quality online adjunct instructor candidates and described the steps that we took to improve our screening and hiring process. We discussed issues associated with collecting and using performance ratings in the context of a remote screening and hiring…

Introduction: Numerous studies have investigated the use of Wechsler tests on individuals with visual impairments. However, few studies have examined the utilization of the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV) for such individuals. This study investigated the reliability and validity of the WISC-IV Verbal…

The emergence of Educational Robotics (ER) and its rapid spread across all levels of education in recent years has drawn attention to the need for further training in this discipline. In this study we discuss the panorama of teacher training research in ER and make recommendations for institutions that intend to implement ER teacher training…

Smartphones are no longer just a communication tool, but also a means of information exchange by students. Smartphone may also positively contribute to students' higher order thinking skills (HOTS). This research aimed to determine smartphone usage intensity, students' HOTS level, and the effect of smartphone usage intensity on students' HOTS in…

Purpose: The aim of this study was to add further knowledge about the usefulness of the Voice Range Profile (VRP) assessment in clinical settings and research by analyzing VRP dual-microphone equipment precision, reliability, and room effect. Method: Test-retest studies were conducted in an anechoic chamber and an office: (a) comparing sound…

Author Randall Langston feels that mentoring should never be viewed as a chore but rather a dynamic and transformational opportunity to impact a student's life. Often, the legacy that some people leave is the professional relationships they have forged with others. In fact, it's not unusual to hear keynote and other conference presentations in…

A software to calculate the net charge and to predict the isoelectric point (pI) of a polypeptide is developed in this work using the graphical programming language LabVIEW. Through this instrument the net charges of the ionizable residues of the chains of the proteins are calculated at different pH values, tabulated, pI is predicted and an Excel…

Whenever classification decisions are made on educational tests, such as pass/fail, or basic, proficient, or advanced, the consistency and accuracy of those decisions should be estimated and reported. Methods for estimating the reliability of classification decisions made on the basis of educational tests are well-established (e.g., Rudner, 2001;…

This study examined the inter-day reliability and repeatability of change-of-direction (COD) performance to determine the minimum number of measurement trials required to represent a stable athlete's performance. Twenty-three university basketball players performed seven COD trials. Identical tests were performed two weeks later to evaluate…

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for…

Although preschoolers have strong expectations about the pedagogical nature of pointing gestures (Csibra & Gergely, 2006), more recent work has shown that preschoolers prefer to use informants' spoken language, not their pointing gestures, to make judgments about their reliability (Palmquist & Jaswal, 2015). Here, we explored children's…

This methodological paper examines current conceptions of reliability in chemistry education research (CER) and provides recommendations for moving beyond the current reliance on reporting coefficient alpha (a) as reliability evidence without regard to its appropriateness for the research context. To help foster a better understanding of…
