Play researchers and theorists have cautioned that children's early play is changing in a manner that is detrimental to their development. Meanwhile U.S. governmental pressures and increasingly higher standards for education are changing the landscape of kindergarten and early learning. This study investigates the relationship between children's…

The positive side of employment during studies is the increase of net investments in human capital. The main objective of this paper is to discover factors influencing the work of students in Serbia, Bosnia and Herzegovina and Montenegro and to compare students' employment in these three Western Balkan countries. Quantitative analysis based on…

Literacy requires reading comprehension, and fostering reading skills is an essential prerequisite to and a synergistic enabler of the development of writing skills. Reading comprehension in the chemical sciences not only consists of the understanding of text but also includes the reading and processing of data tables, schemes, and graphs. Thus,…

The aim of this study was to explore the influence of parental intolerance of Uncertainty (IU), sensory sensitivity (SS) and Broader Autism Phenotype (BAP), as well as the severity of their children's autism symptoms and co-morbid symptoms, on the mental health of Chinese parents of children with autism spectrum disorder (ASD). One hundred and…

We examined whether grief and general distress reactions characterized mothers' reactions to their child's ASD diagnosis, and whether these two types of reactions had unique predictors. Hierarchical regression analyses were conducted on data collected from 362 mothers recruited from the Interactive Autism Network (IAN). The mothers were…

This two-article dissertation examined the impact of enhanced educational dialogue, in terms of periodic email feedback on course progress and an invitation to participate in a discussion board, on student achievement and course satisfaction in an introductory statistics course offered in an independent study setting. Participants in the study…

Of the several measures of optimism presently available in the literature, the Life Orientation Test (LOT; Scheier & Carver, 1985) has been the most widely used in empirical research. This article explores, confirms, and cross-validates the factor structure of the Chinese version of the LOT with ordinal data by using robust weighted least…

A safe environment is a prerequisite for productive learning. This paper represents the first large-scale analysis of how feelings of safety at school affect educational outcomes. Using a unique longitudinal dataset of survey responses from New York City middle school students, the paper provides insight into the causal relationship between…

The past two decades have shown an unexpected effectiveness of "Web-scale" data in natural language processing. Even the simplest models, when paired with unprecedented amounts of unstructured and unlabeled Web data, have been shown to outperform sophisticated ones. It has been argued that the effectiveness of Web-scale data has…

For decades, higher education institutions have been increasingly reliant upon part-time faculty. As the role of part-time faculty in colleges and universities has evolved and gained prominence, it is increasingly important to gain a deeper understanding of their perceptions of job involvement considered as potential predictor of turnover and…

A key issue in quasi-experimental studies and also with many evaluations which required a treatment effects (i.e. a control or experimental group) design is selection bias (Shadish el at 2002). Selection bias refers to the selection of individuals, groups or data for analysis such that proper randomization is not achieved, thereby ensuring that…

Factor score estimation is a controversial topic in psychometrics, and the estimation of factor scores from exploratory factor models has historically received a great deal of attention. However, both confirmatory factor models and the existence of missing data have generally been ignored in this debate. This article presents a simulation study…

Over the past decade educational research has been stimulated by new legislation such as the No Child Left Behind Act. Increasing emphasis is being placed on accurately quantifying the success of treatment programs through student achievement scores, so precise estimation is vital for establishing the efficacy of new methodology. Ranked set…

Compressed sensing (CS) is an emerging signal acquisition framework that goes against the traditional Nyquist sampling paradigm. CS demonstrates that a sparse, or compressible, signal can be acquired using a low rate acquisition process. Since noise is always present in practical data acquisition systems, sensing and reconstruction methods are…

In this paper, we discuss the importance of teaching power considerations in statistical hypothesis testing. Statistical power analysis determines the ability of a study to detect a meaningful effect size, where the effect size is the difference between the hypothesized value of the population parameter under the null hypothesis and the true value…
