The purpose of this meta-analysis was to examine the effect of situated learning on the academic performance of students with and without disabilities in inclusive general education classrooms. While previous research has reported the overall effectiveness of situated learning, relatively few studies have been conducted to investigate how situated…

The purpose of this meta-analytic review is twofold. First, the authors estimate the impact of K-8 summer literacy interventions on reading achievement. They measure reading achievement using a composite outcome and specific measures of word reading and fluency, vocabulary, and comprehension. Second, they examine the moderating role of the…

There is a considerable body of literature on research on environmental knowledge, attitude and action. A lot of research has occurred on the primary and secondary school populations and the general population. However, much less emphasis has been placed on studies that concern post-compulsory education students in the range from 16 to 18 years…

Since the National Reading Panel report and passage of No Child Left Behind, one particular reading instrument, "Dynamic Indicators of Basic Early Literacy Skills" (DIBELS), has gained nationwide attention. As a result, DIBELS has been used in thousands of schools across the nation as a means of early identification, intervention, and…

Objectives: This qualitative synthesis explores the voices of children in the context of child custody disputes over the last 20 years. The purpose was to (1) systematically retrieve qualitative studies to explore children's views and preferences in the context of decision making postseparation and divorce and (2) explore how children's voices are…

This paper reviews recent studies on the effectiveness of services and incentives offered to disadvantaged youths both in the US and abroad. We focus our analysis on three types of interventions: mentoring, educational services, and financial rewards. The objective of this article is threefold. First, we explain alternative theoretical points of…

A quantitative, coordinate-based meta-analysis combined data from 354 participants across 22 fMRI studies and one positron emission tomography (PET) study to identify the differences in neural correlates of figurative and literal language processing, and to investigate the role of the right hemisphere (RH) in figurative language processing.…

Research synthesis of evaluation findings is a multistep process. An investigator identifies a research question, acquires the relevant literature, codes findings from that literature, and analyzes the coded data to estimate the average treatment effect and its distribution in a population of interest. The process of estimating the average…

Objective: The present study quantitatively reviewed the literature on sudden gains in psychological treatments for anxiety and depression. The authors examined the short- and long-term effects of sudden gains on treatment outcome as well as moderators of these effects. Method: The authors conducted a literature search using PubMed, PsycINFO, the…

What is the relation between competition and performance? The present research addresses this important multidisciplinary question by conducting a meta-analysis of existing empirical work and by proposing a new conceptual model--the opposing processes model of competition and performance. This model was tested by conducting an additional…

This study examined the discriminant and criterion-related validity of achievement goals in predicting academic achievement. Analysis of 151 studies yielded 172 independent samples (N = 52,986) with correlations among achievement goals and between achievement goals and academic achievement. The discriminant validity of achievement goals in the 2-,…

The internal/external frame of reference (I/E) model and dimensional comparison theory posit paradoxical relations between achievement (ACH) and self-concept (SC) in mathematics (M) and verbal (V) domains; ACH in each domain positively affects SC in the matching domain (e.g., MACH to MSC) but negatively in the nonmatching domain (e.g., MACH to…

This paper presents the first experimental evidence on the effects of live versus internet media of instruction. Students in a large introductory microeconomics course at a major research university were randomly assigned to live lectures versus watching these same lectures in an internet setting, where all other factors (e.g., instruction,…

The purpose of this paper is to provide a summary of evidence for the effectiveness and safety of commonly used crisis interventions in schools, such as critical incident stress debriefing (CISD), critical incident stress management (CISM), and psychological debriefing (PD). Two researchers independently searched relevant databases for reviews and…

Storm, Tressoldi, and Di Risio (2010) rely on meta-analyses to justify their claim that the evidence for psi is consistent and reliable. They manufacture apparent homogeneity and consistency by eliminating many outliers and combining databases whose combined effect sizes are not significantly different--even though these combined effect sizes…
