Introduction: Motivation is an important issue in both face-to-face and computer-supported collaborative learning. There are several approaches for enhancing motivation, including group awareness tools that provide feedback on the group's motivation. However, this feedback was rarely unconfounded with other constructs. Additionally, it is…

Despite the claimed success of the 1996 Welfare Reform, little research using multivariate regression has examined changes in multiple public safety-net programs. Thus, we still do not know whether public safety-net programs for the poor have shrunk or increased nationwide, along with the sharp declines in cash assistance. Using state-level data…

Some of the most male-dominated science, technology, engineering and mathematics occupations and degree programmes are found in the world's most affluent societies. This article assesses whether gender gaps in "attitudes" follow similarly surprising patterns. Multivariate analysis of eighth-graders' affinity for mathematics and…

A total of 726 youths presenting a severe addiction were evaluated at the time of their request for services in an addiction rehabilitation center. Results show that the more delinquent youths have a more severe profile of substance use, thus confirming the strong association between psychoactive substance (PAS) use severity and delinquency. Girls…

This study investigates the relations between teachers' attitudes towards persons with intellectual disability (ID), in-service training on ID, and prior contacts with persons with ID. A sample of Canadian elementary school teachers (N?=?118) completed the Attitudes Toward Intellectual Disability Questionnaire, which measures cognitive, affective…

The purpose of this quantitative study was to determine if there was a relationship between the TCAP test and Pearson Benchmark assessment in elementary students' reading and language arts and math performance in a northeastern Tennessee school district. This study involved 3rd, 4th, 5th, and 6th grade students. The study focused on the following…

The purpose of this study was to determine if attending a four-year-old preschool program had an impact on the academic achievement of elementary age students. With limited funding and the demands of No Child Left Behind legislation, schools are constantly evaluating the effectiveness and cost of ongoing programming. In addition, educational…

Many scholars have researched reading-to-writing relations, some of which found reading to be an effective enhancer of writing (Al-Jarf, 2004; Asencior, 2006; Lee, 1986a; Lee & Riley, 1990; Perez-Sotelo & Gonzalez-Bueno, 2003; Shang, 2007). Similar beginner college student samples were used previously by Asencior (2006), Perez-Sotelo and…

Parents play an important role in influencing adolescent health behaviors and parenting practices may be an important pathway through which social disadvantage influences adolescent health behaviors that can persist into adulthood. This analysis uses the National Longitudinal Study of Adolescent Health to examine how parenting practices mediate…

In the case of trials with nested data, the optimal allocation of units depends on the budget, the costs, and the intracluster correlation coefficient. In general, the intracluster correlation coefficient is unknown in advance and an initial guess has to be made based on published values or subject matter knowledge. This initial estimate is likely…

In this article we present an exploratory tool for extracting systematic patterns from multivariate data. The technique, hierarchical segmentation (HS), can be used to group multivariate time series into segments with similar discrete-state recurrence patterns and it is not restricted by the stationarity assumption. We use a simulation study to…

To understand how learners of respective types respond to marketing games, a joint space generated by canonical correlation analysis is used to recreate Kolb's learning style-type plot and locate business students as points within it according to their learning style types. Two hundred twenty-three undergraduate students played The Marketing Game!…

We apply collaborative filtering (CF) to dichotomously scored student response data (right, wrong, or no interaction), finding optimal parameters for each student and item based on cross-validated prediction accuracy. The approach is naturally suited to comparing different models, both unidimensional and multidimensional in ability, including a…

The purpose of the study was to validate a theoretical model of diagnostic, formative classroom assessment called, "Proximal Assessment for Learner Diagnosis" (PALD). To achieve its purpose, the study employed a two-stage, mixed-methods design. The study utilized multiple data sources from 11 elementary level mathematics teachers who…

The purpose of this study was to identify what leadership behaviors are associated with each of Spillane's (2006) three conceptually distinct forms of distributed leadership, and to determine whether specific influence tactics (Yukl, Seifert & Chavez, 2008) are differentially associated with each form. A two-phased, mixed methods design was…
