Few concepts are more noted in the leadership effects research than vision. It is a cardinal element in the school improvement equation as well. Yet, it remains one of the least well-specified components of that algorithm. Based on a comprehensive review of the research on effective leadership and school improvement from 1995 to 2012, we bring…

Theoretical ambiguities in curriculum studies result in conceptual mayhem. Accordingly, they hinder the development of the complicated conversation on curriculum as a verb. This article aims to contribute to reconceptualizing curriculum studies as a dynamic social practice that aspires to thinking and acting with intelligences and sensitivity so…

Reading ability is comprised of several component processes. In particular, the connection between the visual and verbal systems has been demonstrated to play an important role in the reading process. The present study provides a review of the existing literature on the visual verbal connection as measured by two tasks, rapid serial naming and…

Intelligent Tutoring Systems (ITS) are computer programs that model learners' psychological states to provide individualized instruction. They have been developed for diverse subject areas (e.g., algebra, medicine, law, reading) to help learners acquire domain-specific, cognitive and metacognitive knowledge. A meta-analysis was conducted on…

In single-case research, the multiple baseline design is a widely used approach for evaluating the effects of interventions on individuals. Multiple baseline designs involve repeated measurement of outcomes over time and the controlled introduction of a treatment at different times for different individuals. This article outlines a general…

Problem Statement: A number of recent studies on constructivism that have been conducted separately (independently) have arrived at very different results. Throughout the ten-year period in which the constructivist approach has been applied, there have been studies that have researched the effect of the newly-introduced approach on student…

We review the effectiveness of first-year seminars based on the widely used criteria of first-year grades and the 1-year retention rate. Meta-analytic results indicate that first-year seminars have a small average effect on both first-year grades (k = 89, N = 52,406, d = 0.02) and the 1-year retention rate (k = 195, N = 169,666, d = 0.11). We…

Improvements in students' learning achievement have lagged behind in low-and middle-income countries despite significant progress in school enrollment numbers. Large-scale early grade reading assessments (e.g., "Annual Status of Education Report" [ASER], 2013; EdData II, n.d.) have shown low reading rates and worryingly high…

Background: This article revisits an article published in Evaluation Review in 2005 on sample size estimation and power analysis for group-randomized trials. With help from a careful reader, we learned of an important error in the spreadsheet used to perform the calculations and generate the results presented in that article. As we studied the…

Based on a synthesis of unpublished transformational school leadership (TSL) research completed during the last 14 years, this study inquired into the nature of TSL and its effects on student achievement using review methods including standard meta-analysis and vote-counting techniques. Results identify a wider range of TSL practices than…

Two previous literature review-based studies have provided important insights into mobile learning, but the issue still needs to be examined from other directions such as the distribution of research purposes. This study takes a meta-analysis approach to systematically reviewing the literature, thus providing a more comprehensive analysis and…

Background: Research into the neuropsychology of pediatric obsessive--compulsive disorder (OCD) reveals inconsistent results, limiting the ability to draw conclusions about possible neurocognitive deficits in youth with OCD. The aim of this study was to conduct a meta-analysis of the available literature. Methods: We identified 36 studies, of…

Optimal levels of treatment fidelity, a critical moderator of intervention effectiveness, are often difficult to sustain in applied settings. It is unknown whether performance feedback, a widely researched method for increasing educators' treatment fidelity, is an evidence-based practice. The purpose of this review was to evaluate the current…

Background: Considerable prior research targeting African American children has focused on the pervasiveness of problematic behavior and negative risk factors associated with their development, however the influence of family on better behavioral health outcomes has largely been ignored. Objective: The purpose of this review is to examine…

The aim of the present study is to conduct a systematic review research which focuses on research studies into the school practicum. In order to identify the main issues and also to provide a contemporary picture of practicum, 114 studies published on the topic are reviewed and analysed in terms of: (i) aims, (ii) main participants, (iii)…
