A Longitudinal Process Model Evaluating the Effects of Cooperative Learning on Victimization, Stress, Mental Health, and Academic Engagement in Middle School

The effects of cooperative learning on self-reported peer relations, peer support, and classroom engagement among students with disabilities

Students with disabilities are at an increased risk of experiencing poorer quality peer relationships than those without disabilities. Previous school-based efforts to promote positive peer interactions among students with and without disabilities have included individual skill development and broader initiatives such as inclusive school practices. In the current study, we investigate the effects of cooperative learning (CL) on peer relationships, peer academic supports, and classroom engagement of middle school students with and without disabilities over two years. Using 4 waves of data from a cluster randomized trial of middle schools, we hypothesized that CL would create positive gains in study outcomes among all students, but we anticipated that effects would be more pronounced among students with disabilities. Results confirmed these hypotheses and highlighted the potential role of CL in creating greater social integration among students with and without disabilities. The implications of these findings for practitioners and policymakers are discussed.

Universal School-Based Substance Use Prevention Using Technology-Supported Cooperative Learning

Substance use in adolescence is a significant public health issue, particularly in early-to-mid adolescence, which represents a window of risk in the etiology of substance abuse and dependence. Substance use during this development period often results from affiliation with deviant peers, who model, facilitate, and reinforce use. Existing school-based substance use prevention programs have historically aimed to build adolescent knowledge regarding the dangers of substance use and/or enhance peer refusal skills. Research finds that these programs have had some success in reducing substance use, but meta-analyses report that average effect sizes are small. In a small one-year cluster randomized trial (12 middle and high schools; N = 813 students; ClinicalTrials.gov: NCT04478240), cooperative learning (CL) was implemented with the support of specialized technology and evaluated for its ability to reduce deviant peer affiliation and, in turn, reduce substance use. CL is a structured approach to small-group learning that provides at-risk youth with the opportunity to build friendships with more prosocial youth, interrupting the process of deviant peer clustering. Multi-level modeling revealed intervention effects for deviant peer affiliation and alcohol use across the sample, while tobacco use was significantly reduced among non-White students; intervention effects for marijuana use were only marginally significant. Effects for dosage were found for all outcomes, suggesting that every lesson taught had a significant impact. We conclude that CL, delivered with the aid of specialized technology, represents a viable option for universal substance use prevention. Future research should attempt to combine this approach with evidence-based prevention curricula.
