Background: Calls for the reform of education in science, technology, engineering, and mathematics (STEM) have inspired many instructional innovations, some research based. Yet adoption of such instruction has been slow. Research has suggested that students' response may significantly affect an instructor's willingness to adopt different types of…

The purpose of this study was to create a new scale with a validated construct to measure professional identity development in students being prepared to become new practitioners. Using the new survey instrument (named the Professional Identity Five-Factor Scale), data were collected from a polytechnic with students enrolled in a wide range of…

The Beach Center Family Quality of Life Scale is an internationally validated instrument for measuring family outcomes. To revise the scale for better alignment with the Family Quality of Life theory, the authors excluded non-outcome items in this revision. In this study, we examined reliability and validity of the revised scale (i.e., the FQoL…

Knowing an equation has a unique solution is important from both a modelling and theoretical point of view. For over 70 years, the approach to learning and teaching "well posedness" of initial value problems (IVPs) for second- and higher-order ordinary differential equations has involved transforming the problem and its analysis to a…

The Reynolds Intellectual Assessment Scales, Second Edition (RIAS-2; Reynolds & Kamphaus, 2015) is an intelligence test for those aged 3 to 94 years. It contains eight subtests designed to assess general intelligence, verbal and nonverbal intelligence, memory, and processing speed. The two subtests targeting processing speed are new to the…

National attention on whole-of-school approaches to decrease children's sedentary behavior and increase physical activity includes movement integration (MI) in classrooms. The purpose of this study was to describe instrument development, reliability, and validity of the System for Observing Student Movement in Academic Routines and Transitions…

Until recently, there were four sources of large-scale self-report survey data on victim rates, cross-nationally: EU Kids Online, Global School Health Survey, Trends in International Mathematics and Science Study, and Health Behaviour of School-aged Children. Smith, Robinson, and Marchi (2016) examined the internal validity and external validity…

The sheet resistance of a conducting material of uniform thickness is analogous to the resistivity of a solid material and provides a measure of electrical resistance. In 1958, L. J. van der Pauw found an effective method for computing sheet resistance that requires taking two electrical measurements from four points on the edge of a simply…

The testing effect is the enhanced retention of learned information by individuals who have studied and completed a test over the material relative to individuals who have only studied the material. Although numerous laboratory studies and simulated classroom studies have provided evidence of the testing effect, data from a natural class setting…

The notion of flow of a proof encapsulates mathematical, didactical, and contextual aspects of proof presentation. A proof may have different flows, depending on the lecturer's choices regarding its presentation. Adopting Perelman's New Rhetoric (PNR) as a theoretical framework, we designed methods to assess aspects of the flow of a proof. We…

The purpose of this study was to investigate the relationship between the Penn Interactive Peer Play (PIPPS-HK) and the Preschool Play Behavior Scale (PPBS-HK) to establish concurrent validity of both scales. A total of 1,622 children age 3 to 6 and 152 teachers in 10 kindergartens (about 160 students and 15 teachers randomly selected from each…

The theoretical reason for the presence of differential item functioning (DIF) is that data are multidimensional and two groups of examinees differ in their underlying ability distribution for the secondary dimension(s). Therefore, the purpose of this study was to determine how much the secondary ability distributions must differ before DIF is…

Although peer nomination measures have been used by researchers for nearly a century, common methodological practices and rules of thumb (e.g., which variables to measure; use of limited vs. unlimited nomination methods) have continued to develop in recent decades. At the same time, other key aspects of the basic nomination procedure (e.g.,…

There are two primary means to prevent the abuse of collegiality and transform it into a shield to protect the most vulnerable. First, colleges and universities should follow the examples of their peers by developing clear definitions of what types of behavior constitute collegiality and what types of activity are protected as academic freedom or…

The present study explored the utility of a widely used performance-based assessment of children's readiness skills as a kindergarten entry assessment. In a sample of 520 kindergarten students across 52 classrooms, we compared students' school readiness skills as assessed by teachers using Teaching Strategies GOLD (TS GOLD) to direct assessments…
