Recent research demonstrates that in many countries gender differences in mathematics achievement have virtually disappeared. Expectancy-value theory and social cognition theory both predict that if gender differences in achievement have declined there should be a similar decline in gender differences in self-beliefs. Extant literature is…

Disordered eating behaviors and substance use are two risk factors for the development of serious psychopathology and health concerns in adulthood. Despite the negative outcomes associated with these risky behaviors, few studies have examined potential associations between these risk factors as they occur during adolescence. The importance of…

Research indicates that many elementary students do not comprehend that the equal sign is an indication that an equality relation exists between two structures. Instead, they perceive the equal sign as an indication that a particular procedure is to be performed. As students mature, and as their exposure to the equal sign and equality relations in…

The purpose of this quantitative study was to compare the emotional intelligence competencies of a group of technical experts with high skills in problem-solving, leadership and mentoring (Group A) with a group of technical experts with lower skills in problem solving, leadership, and mentoring (Group B) at a semiconductor manufacturing factory in…

This book shows school leaders how they can infuse their daily practice with an examination of the actions they take to improve their schools. It identifies eight steps that inform the school improvement process and boost student achievement. These steps provide a framework for examining school improvement as part of a genuine process with meaning…

Clustering is one of the most common data mining tasks, used frequently for data organization and analysis in various application domains. Traditional machine learning approaches to clustering are fully automated and unsupervised where class labels are unknown a priori. In real application domains, however, some "weak" form of side…

This discussion paper compares and contrasts "inductive" and "deductive" research approaches as described by Trochim (2006) and Plano Clark and Creswell (2007). It also examines the "exploratory" and "confirmatory" approaches by Onwueghuzie and Leech (2005) with respect to the assumption each holds about the nature of knowledge. The paper starts…

Convexity-based measures of shape compactness provide an effective way to identify irregularities in congressional district boundaries. A low convexity coefficient may suggest that a district has been gerrymandered, or it may simply reflect irregularities in the corresponding state boundary. Furthermore, the distribution of population within a…

First-year physics laboratories are often driven by a mix of goals that includes the illustration or discovery of basic physics principles and a myriad of technical skills involving specific equipment, data analysis, and report writing. The sheer number of such goals seems guaranteed to produce cognitive overload, even when highly detailed…

DataToText is a project developed where the user communicates the relevant information for an analysis and DataToText computer routine produces text output that describes in words, tables, and figures the results from the analyses. Two extended examples are given, one an example of a moderator analysis and the other an example of a dyadic data…

Aspiring school leaders rarely emerge from their principal preparation programs fully ready for the challenges that await them as new administrators, with much evidence revealing the need for continued mentoring and professional development. The author developed graduate course content that taught students the knowledge, skills and dispositions of…

This article explores the nature of the experiential data used in reflective learning, reflective practice and ipsative research in higher education. Much of what has been written about experiential learning has focused on the nature of the reflective process. By contrast, this article explores the nature of the experiential data that underpins…

The purpose of this study was to examine how school psychologists implemented the problem-solving consultation process within a computer-simulated school environment. Four school psychologists were recruited to complete three simulated consultation cases. The school environment was computer generated and all of the teachers and target students…

Many self-studies focus on an individual or several teacher educators. Although there have been self-studies undertaken by teacher education administrators, there is relatively little research that focuses specifically on an administrator's program development work in teacher education. This self-study examines one teacher education…

In this paper we explored text production differences in an expository text production task between writers who looked mainly at the keyboard and writers who looked mainly at the monitor. Eye-tracking technology and keystroke-logging were combined to systematically describe and define these two groups in respect of the complex interplay between…
