Decades of research indicate that peer interaction, where individuals discuss or work on a task collaboratively, may be beneficial for children's and adolescents' learning. Yet, we do not know which features of interaction may be related to learning from peer interaction. This meta-analysis examined results from 62 articles with 71 studies into…

Previous meta-analyses of the effects of peer tutoring on academic achievement have been plagued with theoretical and methodological flaws. Specifically, these studies have not adopted both fixed and mixed effects models for analyzing the effect size; they have not evaluated the moderating effect of some commonly used parameters, such as comparing…

A meta-analytic review of group comparison design studies evaluating peer-assisted learning (PAL) interventions with elementary school students produced positive effect sizes (ESs) indicating increases in achievement. PAL interventions were most effective with younger, urban, low-income, and minority students. Interventions that used…

Meta-analysis was used to examine social, self-concept, and behavioral effects of peer-assisted learning (PAL) interventions with elementary school students. An electronic search of PsycINFO and ERIC databases resulted in 36 relevant PAL studies. Overall, effect sizes were small to moderate across the 3 outcome variable domains. Both social and…

Conducts a meta-analysis of supplemental, adult-instructed one-to-one reading interventions for elementary students (N=1,539) at risk for reading failure. Results indicate that interventions using trained volunteers or college students were highly effective. Studies comparing one-to-one with small-group supplemental instruction showed no advantage…
