Three methods of synthesizing correlations for meta-analytic structural equation modeling (SEM) under different degrees and mechanisms of missingness were compared for the estimation of correlation and SEM parameters and goodness-of-fit indices by using Monte Carlo simulation techniques. A revised generalized least squares (GLS) method for…

A great deal of research has been carried out over the past two decades related to the effectiveness of computer-assisted teaching and learning. This large body of work, however, has not produced unequivocal findings, especially in the area of CALL. Our study takes a systematic look at what dedicated meta-research since 1991 might have contributed…

This paper presents an analysis of papers delivered at the ICALT 2004 conference, in order to understand the current research issues relating to Learning Objects (LOs). The major research results are summarized, and the papers are classified according to the definition of LO used and the approach taken (technical, pragmatic or pedagogic). The…

A meta-analysis examining the effectiveness of Behavioral Parent Training for children and adolescents with externalizing behaviors and disruptive behavior disorders was conducted with 79 outcome studies conducted between 1966 and 2001. Separate analyses were conducted for studies employing between-subjects, within-subjects, and single-subject…

This meta-analysis compared the academic achievement of elementary students who received either traditional instruction or traditional instruction supplemented with CAI. From the 68 effect sizes, an overall mean effect size of 0.342 was calculated, indicating that, on average, students receiving traditional instruction supplemented with CAI…

The last decade has seen a noticeable increase in the number of treatment outcome studies for pediatric obsessive-compulsive disorder (OCD). The present article describes a meta-analysis of this literature with the aim of quantifying treatment effects and examining the extent to which various patient or treatment variables are related to outcome.…

Supporting people with disabilities in expressing preferences and making choices is a core value in positive behavior support. Indeed, in recent years, the field has increasingly focused its attention on the importance of making choices and the potential benefits of choice-making opportunities in enhancing the quality of life of people with…

This paper focuses on two key aspects of self-evaluation in adult education and training through the perspective of (a) a social-cognitive framework which is used to categorise those factors that enhance self-efficacy and self-evaluation, and (b) the accuracy of self-evaluation. The social-cognitive framework categorises the factors that enhance…

Ten years of instrument development are summarized and placed within a framework for assessing the impact of technology in education. Seven well-validated instruments spanning the areas of attitudes, beliefs, skills, competencies, and technology integration proficiencies are presented, along with data analysis examples. These instruments are…

In this article we discuss two impediments to widespread adoption and implementation of cognitive-behavioral intervention (CBI) procedures by teachers of students with behavior disorders. First, its principles can be difficult, even for researchers and other specialists. Second, despite ample demonstration that teachers can be taught CBI…

Efficacy research on video based instruction for children with autism is a promising area for practitioners and researchers. Researchers are successfully using video to teach a variety of social and functional skills. This literature review synthesizes these findings and examines critical features of each of the studies that contribute most to the…

The National Early Literacy Panel (NELP) was appointed in 2002 and carried out its work under the auspices of the National Center for Family Literacy (NCFL). NELP's primary goal was to identify interventions, parenting activities, and instructional practices that promote the development of children's early literacy skills. The National Institute…

A meta-analysis of 41 studies was conducted to examine the strength of the relation between parenting (positive control, negative control and responsiveness) and self-regulation in preschoolers. Results revealed significant associations between both types of parental control and self-regulation, with effect sizes being small in magnitude. There…

Background: The differential effectiveness of parent training has led researchers to examine a variety of child, parent, and familial variables that may predict treatment response. Studies have identified a diverse set of child, parent psychological/behavioral and demographic variables that are associated with treatment outcome and dropout.…

A meta-analysis of 50 studies was conducted to investigate whether juvenile delinquents use lower levels of moral judgment than their nondelinquent age-mates and, if so, what factors may influence or moderate the developmental delay. The results show a lower stage of moral judgment for juvenile delinquents (d = 0.76). Effect sizes were large for…
