The purpose of this review was to examine the methods used to conduct meta-analyses of single-subject research involving students with and at-risk for disabilities. Specifically, the procedures used for preparing, aggregating, analyzing, and evaluating single-subject data across 68 primary syntheses were examined. In addition to these…

In recent years the majority of California community colleges evaluated for re-accreditation received sanctions requiring documented improvement in the integration of college planning and budgeting processes. This study explores the challenges colleges face and the best practices utilized by successful colleges in implementing integrated…

Accurate prediction of which candidates show the most promise of success in dental school is imperative for the candidates, the profession, and the public. Several studies suggested that predental GPAs and the Dental Admissions Test (DAT) produce a range of correlations with dental school performance measures. While there have been similarities,…

The purpose of this study was to determine if meta-analysis can be used to enhance efforts to identify evidence-based practices (EBPs). In this study, the quality of included studies acted as the moderating variable. I used the quality indicators for experimental and quasi-experimental research developed by Gersten, Fuchs, Coyne, Greenwood, and…

Objective: To assess how threshold oppositional defiant disorder (ODD), inattention, and hyperactivity-impulsivity affect the response to atomoxetine versus methylphenidate. Method: Systematic review of randomized controlled trials (RCTs; greater than or equal to 6 weeks follow-up). The primary measure was core symptom response--greater than or…

Confidence intervals (CIs) and effect sizes are essential to encourage meta-analytic thinking and to accumulate research findings. CIs provide a range of plausible values for population parameters with a degree of confidence that the parameter is in that particular interval. CIs also give information about how precise the estimates are. Comparison…

The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (Grades 6-8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings from the studies indicate large effect sizes for…

The literature indicates that perceived racism tends to be associated with adverse psychological and physiological outcomes; however, findings in this area are not yet conclusive. In this meta-analysis, we systematically reviewed 66 studies (total sample size of 18,140 across studies), published between January 1996 and April 2011, on the…

The article continues the discussion of the five quality principles proposed by Heikkinen, Huttunen, and Syrjala, published in 2007 in "Educational Action Research". In the present article, the authors reconsider the five principles: historical continuity; reflexivity; dialectics; workability; and evocativeness. These five principles are…

We present three models of equity and show how these, along with the statistical measures used to evaluate results, impact interpretation of equity in education reform. Equity can be defined and interpreted in many ways. Most equity education reform research strives to achieve equity by closing achievement gaps between groups. An example is given…

In this meta-analysis, we give a comprehensive overview of the effects of meditation on psychological variables that can be extracted from empirical studies, concentrating on the effects of meditation on nonclinical groups of adult meditators. Mostly because of methodological problems, almost 3/4 of an initially identified 595 studies had to be…

We analyzed several studies of non-verbal communication (prosody and facial expressions) completed in our lab and conducted a secondary analysis to compare performance on receptive vs. expressive tasks by adolescents with ASD and their typically developing peers. Results show a significant between-group difference for the aggregate score of…

The acknowledgement that educational achievement is highly dependent on successful reading development has led to extensive research on its underlying factors. A strong argument has been made for a causal relationship between reading and phoneme awareness; similarly, causal relations have been suggested for reading with short-term memory and rhyme…

This succinct and jargon-free introduction to effect sizes gives students and researchers the tools they need to interpret the practical significance of their results. Using a class-tested approach that includes numerous examples and step-by-step exercises, it introduces and explains three of the most important issues relating to the practical…

A recent Meta-Analysis conducted by Apsche, Bass & DiMeo (2010) provided astonishing evidence regarding Mode Deactivation Therapy's (MDT) ability to effectuate change in youth with delinquent traits. Following is a brief review of the results presented in the analysis as a way of highlighting the capacities of MDT and promotes the implementation…
