Most studies in the literature on workplace bullying concentrated on identifying the characteristics of who the bully and the bullied are, bullying behaviors and acts, and the effects of these bullying practices. However, there is not much in the literature about the perception of organizational justice and organizational citizenship behavior…

Abstract Preschoolers' cognitive abilities were assessed each year as part of the Head Start Program requirements. The Head Start PK-4 Center evaluated preschoolers' cognition by administering the Learning Accomplishment Profile-Diagnostic (LAP-D), as a pretest and posttest measure. The LAP-D study used archival data collected from the 2009-2010…

The purpose of this document is to describe the methods RAND used to analyze achievement for 23 personalized learning (PL) schools for the 2012-13 through 2013-14 academic years. This work was performed at the request of the Bill & Melinda Gates Foundation (BMGF), as part of a multi-year evaluation contract. The 23 schools were selected from a…

Recently, the authors have been exploring the use of propensity score methods for developing evidence of program impact. Specifically, they have been developing evidence (after one year of implementation) of the effects of the Math Science Partnership in New York City ("MSPinNYC2") on high school students' achievement--both in terms of…

Previous studies have demonstrated that various psychosocial risks are associated with poor cognitive functioning in children, and these risks frequently cluster together. In the current longitudinal study, we tested a model in which it was hypothesized that cumulative psychosocial adversity of mothers would have deleterious effects on children's…

Classroom discussion boards are a vital part of the online educational experience, providing a venue for peer to peer and student to faculty interactions. However, institutional feedback from students at a large open enrollment university has shown that excess focus on online discussions may lead to fatigue, resulting in lower student…

There is growing recognition that cumulative economic risk places children at higher risk for depressed academic competencies (Crosnoe & Cooper, 2010; NCCP, 2008; Sameroff, 2000). Yet, children's temperamental regulation and the quality of the early childhood classroom environment have been associated with better academic skills. This study is…

Background: Pedagogical content knowledge (PCK) is an interaction of several knowledge bases upon which the teacher makes decisions about what and how to teach. To date, there are no studies in physical education directly documenting relationships between specialized content knowledge (SCK) and PCK. Such relationships have not been empirically…

The willingness to solve conflicts without violence and to strive for a reconciliation of interests is of central significance for the continued existence of democracies. In this paper, we aim to analyze school-related determinants of adolescents' conflict behaviour. Models predicting the conflict styles of "integrating",…

Mass media have numerous effects on children, ranging from influencing school performance to increased or reduced aggression. What we do not know, however, is how media availability in the bedroom moderates these effects. Although several researchers have suggested that bedroom media may influence outcomes by displacing other activities (the…

The present study is an experimental one in nature, to find out the effectiveness of CAI package on in Physics of IX std. students. For this purpose a CAI package was developed and validated. The validated CAI package formed an independent variable of this study. The dependent variable is students' achievements in physics content. In order to find…

In teaching reading, educators strive to find the balance between a code-emphasis approach and a meaning-oriented literacy approach. However, little is known about how different approaches to literacy can benefit bilingual children's early reading acquisition. To investigate the novel hypothesis that children's age of first bilingual exposure can…

Solving mathematics story problems requires text comprehension skills. However, previous studies have found few connections between traditional measures of text readability and performance on story problems. We hypothesized that recently developed measures of readability and topic incidence measured by text-mining tools may illuminate associations…

This study examines the interrelationships among students' motivational beliefs (i.e. achievement goal orientations, perception of classroom goal structure, and self-efficacy), use of self-regulated learning strategies (i.e. elaboration, organization, and metacognitive self-regulation strategies), and achievement in mathematics, by proposing and…

Purpose: The purpose of this study is to investigate the factors which might affect the intention to use interactive whiteboards (IWBs) by university students, using Technology Acceptance Model by the structural equation modeling approach. The following hypothesis guided the current study: H1. There is a positive relationship between IWB…
