Experiences of discrimination and bias are detrimental to the sense of belonging of students of color in higher education. Research has shown the positive benefits of interacting with diverse peers on sense of belonging for students of color attending a primarily White institution (PWI). Additionally, some research has indicated that when students…

The reporting of students' Learning Skills on the Ontario provincial report card provides educators and families with insight into students' work habits. However, the evaluation process is highly subjective. This study explores teachers' perceptions around student learning across demographic and institutional factors. This exploratory study is the…

The school closures due to the ongoing worldwide COVID-19 pandemic have posed an enormous challenge for all entities that take part in our children's education. By displacing learning from schools to home environments, the crisis poses a risk of emotional and motivational problems. Based on research regarding the role of peers, learning in groups,…

The current study tested the developmental significance of both early adolescent sleep quantity and quality for academic competence and internalizing and externalizing problems over the course of 2 years. As part of an accelerated longitudinal study, data were collected from N = 586 Czech adolescents (M[subscript age] = 12.34 years, SD = 0.89,…

This research aims to find how the infrastructure of digital devices within the school and teachers' capacity using digital devices affect student achievement defined as PISA 2018 reading, math, and science scores. The ex post facto co-relational causal research design was employed. The data were obtained from the school questionnaire administered…

This study with 850 students examined the interrelations of students' own and perceived teacher reference norms in combination with estimating the relations of these constructs to self-concept in the domain of mathematics. All reference norms were positively interrelated. Regression models yielded different results across school tracks: In…

Scientific Data Analysis Toolkit (SDAT) is a rigorous, versatile, and user-friendly data analysis add-in application for Microsoft Excel for Windows (PC). SDAT uses the familiar Excel environment to carry out most of the analytical tasks used in data analysis. It has been designed for student use in manipulating and analyzing data encountered in…

There is a growing concern that much of the published research literature is distorted by the pursuit of statistically significant results. In a seminal article, Ioannidis and Trikalinos (2007, "Clinical Trials") proposed an omnibus (I&T) test for significance chasing (SC) biases. This test compares the observed number of studies…

Network meta-analysis (NMA) is gaining popularity for comparing multiple treatments in a single analysis. Generalized linear mixed models provide a unifying framework for NMA, allow us to analyze datasets with dichotomous, continuous or count endpoints, and take into account multiarm trials, potential heterogeneity between trials and network…

The literature exploring the executive function correlates of bilingualism is vast, but to date, few studies have concentrated on children, for whom the bilingual advantage appears even more inconsistent than for adults. We investigate a highly heterogeneous group of children (in terms of bilingual experience and socioeconomic status) and identify…

The main objective of the study was to explore the main predictors that influence academic stress among fourth-grade elementary school students using data from the Panel Study on Korean Children via a least absolute shrinkage and selection operator (LASSO) regularized penalty regression model. The study examined 280 explanatory variables using the…

In this study logistic regression and Lord's Chi Square methods were used to research the items that have DIF. The study utilized Peabody Picture Vocabulary Test (PPVT). The original form of the PPVT includes four options. Three different forms (A, B and C) were formed by removing one of the distractors respectively. The original form of PPVT was…

In the context of cross-sectional surveys, the scope of research on the impact of response enhancing strategies on sample composition and nonresponse bias is vast. This topic has rarely been addressed for panel studies, however, although these are becoming an increasingly important data source in social research. In this article, we evaluate the…

School district consolidation has continued at a rapid pace in the United States, with one in every nine districts consolidating between 2000 and 2015 (Collins forthcoming). The stated aim of consolidation efforts is usually improved efficiency -- growing larger to lower unit costs or improve student outcomes without spending more money (Callahan…

We present noncompetitive adsorption as "particles in a box with one sticky wall." We start with a general model that can be modeled as a simple ordinary differential equation (ODE). To verify the ODE students run a computer simulation. The ODE's solution imperfectly fits the simulation's data. This leads to the diffusion partial…
