Normative adult age-related decrements are well documented for many diverse forms of effortful cognitive processing. However, it is currently unclear whether each of these decrements reflects a distinct and independent developmental phenomenon, or, in part, a more global phenomenon. A number of studies have recently been published that show…

The Technology Acceptance Model (TAM) represents how users come to accept and use a given technology and can be applied to teachers' use of educational technologies. Here the model is extended to incorporate teachers' perceived usability and self-efficacy measures toward the technologies they are currently using. The authors administered a survey…

This article reviews the mechanics of conventional and piecewise growth models to demonstrate the unique affordances of each technique for examining the nature and predictors of children's early literacy learning during the transition from preschool through first grade. Using the nationally representative Family and Child Experiences Survey…

This article provides questionnaire items and a theoretical model of factors predictive of customer loyalty for use by administrators to determine ways to increase repeat purchasing in their continuing education programs. Prior studies in the literature are discussed followed by results of applying the model at one institution and a discussion of…

This study aims to reveal the relationship between the self-perception of five-six-year-old children and the social impact, social preference and various conditions in peer relationships (prosocial behaviour, aggression, asocial behaviour, exclusion, fear-anxiety, hyperactivity and victimisation). Two models are the basis of the objectives for…

Over the past 3 decades, a substantial body of scholarship has examined the effects of school leadership on student learning. Most of this research has framed leadership as an independent variable, or driver for change, in relation to school effectiveness and school improvement. Yet, scholars have observed that leadership is also influenced by…

"Technology," the buzz word for the last ten to fifteen years in South Africa. Technology availability is quite often mistaken for technology adoption and use. Technology has been made available to almost all tertiary institutions and at least some public schools. However, in most tertiary institutions many professors still refuse to use…

A simulation study compared the performance of robust normal theory maximum likelihood (ML) and robust categorical least squares (cat-LS) methodology for estimating confirmatory factor analysis models with ordinal variables. Data were generated from 2 models with 2-7 categories, 4 sample sizes, 2 latent distributions, and 5 patterns of category…

Background: The prevalence of obesity among high school students has risen in recent decades. Many high school students report trying to lose weight and some engage in disordered eating to do so. The obesity proneness model suggests that parents may influence their offspring's development of disordered eating. This study examined the viability of…

In this article, the authors develop and test a differential effects model of university entry versus major selection using a set of common predictors, including background factors (gender and socioeconomic status), academic achievement, and academic self-concept. The research used data from 2 large longitudinal databases from Germany (N = 5,048)…

Purpose: This study aims to investigate school principals' well-being by using the job demands-resources (JD-R) model as a theoretical framework. It aims at making a significant contribution to the development of this model by considering not only job demands and job resources, but also the role of personal resources and personal demands as…

This study aimed at modeling individual and average non-linear trajectories of positional learning using a structured latent growth curve approach. The model is based on an exponential function which encompasses three parameters: Initial performance, learning rate, and asymptotic performance. These learning parameters were compared in a positional…

Community engagement professionals and partners serve as, work with, study, and build the capacity of boundary spanners. To augment knowledge about these functions, the Weerts-Sandmann Boundary Spanning Conceptual Framework (2010) has been operationalized through a survey instrument to examine community engagement boundary-spanning behaviors by…

This is the second of three reports from MDRC's evaluation of the Success for All (SFA) scale-up demonstration, funded under the U.S. Department of Education's Investing in Innovation (i3) competition. The report presents updated findings on SFA's implementation and impacts in the scale-up sites participating in the evaluation. The i3 evaluation…

The main purpose of this paper is to study the relationship between managers' performance in the field of interpersonal, informational and decision-making tasks with organizational health. To measure the indicators of the model, a questionnaire was prepared and distributed among 113 company of Tehran stock Exchange Market. According to the…
