To present the difference in oxidizing strength in concentrated and dilute nitric acid reacting with copper, a simple, facile demonstration of these reactions is designed using a waste plastic bottle, plastic droppers, and syringes, which are costless and easily assembled. This new version can be used to demonstrate the difference in oxidizing…

Research Findings: Although it is well documented that toy play and book sharing shape communication between adults and children in different ways, relatively few studies have compared teacher-child interactions in the two activities. The aim of this observational study was to describe and compare the conversational functions of teachers' and…

Memory decision-making in 26- to 32-month-olds was investigated using visual-paired comparison paradigms, requiring toddlers to select familiar stimuli (Active condition) or view familiar and novel stimuli (Passive condition). In Experiment 1 (N = 108, 54.6% female, 62% White; replication N = 98), toddlers with higher accuracy in the Active…

The testlet design is very popular in educational and psychological assessments. This article proposes a new cognitive diagnosis model, the multiple-choice cognitive diagnostic testlet (MC-CDT) model for tests using testlets consisting of MC items. The MC-CDT model uses the original examinees' responses to MC items instead of dichotomously scored…

The consequence of a change in school leadership (e.g., principal turnover) on student achievement has important implications for education policy. The impact of such an event can be estimated via the popular Difference in Difference (DiD) estimator, where those schools with a turnover event are compared to a selected set of schools that did not…

Autistic individuals are at increased risk of experiencing various forms of victimization during their lifespan. This study analyses the self-reported prevalence of bullying victimization in autistic pre-adolescents and those with subthreshold autistic traits in comparison with peers without neurodevelopmental conditions. The sample was comprised…

The purpose of this research was to investigate if the addition of extra credit affected the overall rate of attendance to synchronous lectures in an online asynchronous course, compared to courses in which no extra credit was offered. Further I investigated if the amount of extra credit made a difference to the rate of attendance. I collected…

To support professional competence development in teacher education, learning environments should allow learners to engage with professional tasks. It is crucial for knowledge and skill transfer in such learning environments to real-life context that preservice teachers perceive the task as authentic. However, due to a lack of prior knowledge,…

This paper investigates vision statements of schools as artifacts expressing the values emphasized by schools, drawing on organizational…

The current proposed study sought to extend the work conducted by Ostrosky et al. (2022). The research extension aimed to include and determine the effectiveness of EBI using three instructional models as group contingencies. The results compared the lecture instructional model and interdependent and individualized EBI research results of 10- and…

The purpose of this study was to determine how various security measures affect performance in two South Carolina middle schools, one high-performing, and one low-performing. This research study determined educators' attitudes toward safety in one high-performing and low-performing school in the low country area of South Carolina. There were five…

The study set out to explore different mathematical difficulties among 877 second-grade children and to test the effect of memorization versus conceptual practices with number combinations. It used a latent profile analysis of baseline measurements of digit writing speed, number combination fluency, multidigit calculation, and number sense skills…

This conceptual study explores the dominant ideologies influencing the economic governance of higher education (HE) and shaping competition within the sector and among universities. It delineates and contrasts four key ideological positions -- neoliberalism, managerialism, shareholderism, and stakeholderism -- and outlines four corresponding types…

A small minority of Irish students attend fee-charging second-level schools. However, media analyses of the backgrounds of those students who go on to more sought-after tertiary educational institutions or degree courses suggest that a disproportionate number of them were attendees at fee-charging schools. There are a few reasons why this might be…

Many children with autism spectrum disorder experience feeding difficulties that can lead to increased health risks (e.g., severe nutrition deficiencies, obesity-related illnesses) if left untreated. Intensive feeding programs that use behavior-analytic interventions have reported positive outcomes for treating challenging behavior associated with…
