Costs and benefits of cooperative learning as a universal school-based approach to adolescent substance use prevention.

Substance use during early adolescence implies a greater likelihood of abuse and dependence in later adolescence or adulthood. In turn, substance abuse and dependence are linked to a variety of maladaptive long-term health-related outcomes that imply significant individual and societal costs. In this paper, we evaluated an approach to substance use prevention that relies on the vital role of peers, who comprise a key risk factor for adolescent substance use. This approach (i.e., cooperative learning, CL) focuses on interrupting the process of deviant peer clustering and providing at-risk youth with the opportunity to build social skills and cultivate friendships with low-risk youth. In addition to testing the efficacy of CL in reducing the number of students who become regular substance users, we also conducted a cost-benefit analysis. Using four waves of data from a cluster-randomized trial (N = 15 middle schools, 1890 students, 47.1% female, 75.2% White, 13.9% of students were receiving special education services), we found that significantly lower percentages of students in the intervention (CL) schools became regular users of tobacco, alcohol, and marijuana. We estimated that the reduction in substance use associated with the implementation of CL resulted in total lifetime benefits of between $1027 and $4621 per student (in 2019 dollars), or between $8.79 and $39.54 for each dollar invested in CL. Benefit/cost ratios would go up to $22.54-$101.39 per dollar invested with the continual implementation of CL, assuming retraining every 5 years. Implications and future research directions are discussed.

Peer learning can modify the reciprocal relationship between peer support and victimization in middle school.

INTRODUCTION: This research investigated how peer victimization and support are reciprocally related and how Cooperative Learning (CL) can reverse the progressive cascade that, unchecked, can culminate in youth mental health problems. METHODS: The sample (N = 1890; 53% male) was derived from a randomized trial of CL in 15 middle schools in the United States. Students were recruited in the 7th grade. Structural Equation Modeling (SEM) was used to fit our cross-lag difference score model across four waves of data. RESULTS: The results indicated a reciprocal relationship between peer support and victimization across time, suggesting the potential for negative experiences with peers to become amplified over time in a "vicious cycle," negatively impacting mental health. Students in intervention schools reported significantly higher levels of peer support and lower levels of victimization, suggesting that CL can intervene in this cycle, with salutary effects on mental health; CL also demonstrated direct effects on mental health. CONCLUSIONS: The present study indicates that low peer support can be both a precursor to and an outcome of victimization, serving to maintain a vicious cycle that compounds negative effects on student mental health. Further, results demonstrate how CL can reverse this cycle. We conclude that CL can be of particular importance to the prevention field as a universal mental health program that does not require the associated stigma of identifying youth at elevated risk for referral to treatment programs.

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

Mental health is a significant concern among young people, particularly during the COVID-19 pandemic. Notably, mental health problems can significantly reduce student performance in school, including both engagement and achievement. Both mental health problems and reduced student performance often arise due to peer victimization, which can include teasing, racial- or gender-based discrimination, and/or physical assault. Stress has been proposed as one mechanism through which victimization influences mental health, and stress can also interfere with academic performance at school, including engagement and achievement. To date, however, no research has evaluated longitudinal associations between victimization and stress, and how these longitudinal patterns may impact adolescent behavior and mental health. In this study, we used data from a 2-year cluster randomized trial of cooperative learning to evaluate an etiological process model that includes (1) longitudinal reciprocal effects between victimization and stress, and (2) the effects of both victimization and stress on student mental health and academic engagement. We hypothesized that victimization and stress would have significant reciprocal effects, and that both would predict greater mental health problems and lower academic engagement. We further hypothesized that cooperative learning would have significant effects on all constructs. We found partial support for this model, whereby stress predicted greater victimization, but victimization did not predict increased stress. While both factors were linked to student outcomes, stress was a more powerful predictor. We also found significant salutary effects of cooperative learning on all constructs. The implications of these results for student behavioral and mental health are discussed.

The Longitudinal Relationship Between Peer Relations and Empathy and their Joint Contribution to Reducing Bullying in Middle School: Findings from a Randomized Trial of Cooperative Learning.

The positive peer relations arising from cooperative learning can contribute to the development of affective empathy, which in turn can reduce bullying (Van Ryzin & Roseth, 2019). However, from a theoretical perspective, the direction of effects between peer relations and empathy could be in the opposite direction, or bi-directional. In the current paper, we employed a process-oriented approach (i.e., cross-lag difference score modeling; McArdle, 2009) to investigate the longitudinal relationship between positive peer relations and affective empathy, as well as their joint effect on bullying. Using four waves of data from a cluster randomized trial including 15 middle schools (7 intervention and 8 control schools; N=1,890 students, 47.1% female, 75.2% White), we found a bi-directional or reciprocal relationship between peer relations and affective empathy, and change in both constructs predicted lower levels of bullying. Cooperative learning predicted positive change in peer relations and affective empathy, as well as lower levels of bullying. These results suggest that the structured social interactions that occur during cooperative learning can enhance student interpersonal relations, and simultaneously the experiential skill building of cooperative learning can contribute to a more profound understanding of the emotional states of others. These effects amplify one another and, in turn, significantly reduce bullying in middle school. Given that cooperative learning has already been demonstrated to enhance academic motivation and achievement (Roseth et al., 2008), we argue that cooperative learning offers an effective, attractive alternative to traditional curriculum-based bullying prevention programs (National Library of Medicine [NLM], NCT03119415).

Reciprocated Friendship as a Mediator of the Effects of Cooperative Learning on Peer Victimization in Middle School.

Peer victimization represents a pervasive problem, particularly for students in middle school. Although curriculum-based prevention programs have generated small to moderate effects on victimization, these effects tend to weaken beginning with the transition to middle school. In this study, we evaluated cooperative learning (CL) as a mechanism to prevent victimization, and evaluated reciprocated friendships as a mediator of these effects. Using four waves of data from a cluster randomized trial of CL (7 intervention and 8 control middle schools; N=1,890 students, 47.1% female, 75.2% White), we found that CL significantly reduced victimization after two years, and these effects were mediated by growth in reciprocated friendship in the first year. We conclude that CL can reduce victimization by providing a means for students to engage in extended social interactions with a wider range of peers and thus creating opportunities for students to forge stronger (i.e., reciprocated) friendships.

The Cascading Effects of Reducing Student Stress: Cooperative Learning as a Means to Reduce Emotional Problems and Promote Academic Engagement.

Adolescents, particularly early adolescents, are vulnerable to stress created by negative peer interactions. Stress, in turn, can lead to increased mental health problems and reduced academic engagement, in addition to negative long-term consequences for cognitive development and physical health. Using four waves (2 years) of data from a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White), we evaluated whether enhancements to peer relations, brought about through carefully structured small-group learning activities (i.e., cooperative learning), could reduce stress and emotional problems and promote academic engagement. We hypothesized that the increased social contact created by cooperative learning would promote greater peer relatedness, reducing student stress and, in turn, reducing emotional problems and promoting academic engagement. Our results confirmed these hypotheses. We conclude that cooperative learning can provide social, behavioral, academic, and mental health benefits for students.

Mediators of Effects of Cooperative Learning on Prosocial Behavior in Middle School.

In this study, we tested the effects of cooperative learning on students' prosocial behavior. Cooperative learning is a small-group instructional technique that establishes positive interdependence among students and, unlike most current school-based programs, does not mandate a formal curriculum. Given the emphasis in cooperative learning on peer reinforcement for positive and helpful behavior during learning activities, we hypothesized that cooperative learning would promote higher levels of prosocial behavior, and that these effects would be mediated by peer relatedness. Using a sample of 1,890 students (47.1% female, 75.2% White) from a cluster randomized trial of 15 middle schools, we found that cooperative learning significantly enhanced prosocial behavior across two years. Mediation was only partial, however, suggesting that additional mechanisms were at work, such as changes to social norms or teacher behavior. Given that cooperative learning has been shown to enhance student engagement and academic achievement in prior research, we argue that cooperative learning should be a central component of teacher training and professional development.

The Effects of Cooperative Learning on Peer Relations, Academic Support, and Engagement in Learning Among Students of Color.

Despite Brown vs. Board of Education, prejudice still exists in the American school system. These attitudes can give rise to negative social experiences for students of color (i.e., discrimination), negatively impacting their mental and physical health and creating disparities in educational outcomes. Rather than seeking to ameliorate these negative experiences, our approach attempts to address the underlying prejudices and, in so doing, reduce these disparities. Using 4 waves of data from a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White), we hypothesized that cooperative learning, which has been shown to reduce prejudice in previous research, would create positive gains in peer relatedness, perceptions of academic support, and engagement in learning, and that gains would be larger for students of color; our results confirmed these hypotheses. Our findings highlight the potential role of cooperative learning in reducing disparities and creating greater equity in education.

Effects of cooperative learning on peer relations, empathy, and bullying in middle school.

Although researchers have developed prevention programs to reduce bullying, the results are mixed, and this may be due to a degree of uncertainty in their theoretical foundation. In particular, these programs share an emphasis on empathy as a personal attribute that can be enhanced among students through the application of specific curricula that will, in turn, contribute to a reduction in bullying behavior. However, the link between empathy and bullying is unclear, as is the ability of bullying prevention programs to actually impact student empathy. In this study, we used a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White) to evaluate the impact of cooperative learning on bullying, and we evaluated whether these effects were mediated by empathy and peer relatedness. Our results indicated that cooperative learning can significantly reduce bullying, and that some of this effect is transmitted via enhancements to affective empathy. Cooperative learning also demonstrated significant positive effects on cognitive empathy, but this did not have an effect on bullying. We also found that the effects of cooperative learning on cognitive and affective empathy were mediated by improvements in peer relatedness. These findings add a degree of clarity to the literature, and also represent the first time, as far as we are aware, that an antibullying program has been found to have significant effects on both cognitive and affective empathy.

Cooperative Learning Effects on Peer Relations and Alcohol Use in Middle School.

We tested a prevention approach aimed at reducing growth in alcohol use in middle school using four waves (2 years) of data from a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White). Our approach exposed students to a broad cross-section of peers through collaborative, group-based learning activities in school (i.e., cooperative learning). We hypothesized that the increased social contact created by cooperative learning would promote greater peer relatedness, interrupting the process of deviant peer clustering and, in turn, reduce escalations in alcohol use. Our results supported these hypotheses, suggesting that the social nature of cooperative learning, and the emphasis on group work and collaboration, can provide social and behavioral as well as academic benefits for students.

From science student to scientist: Predictors and outcomes of heterogeneous science identity trajectories in college.

This 5-year longitudinal study investigates the development of science identity throughout college from an expectancy-value perspective. Specifically, heterogeneous developmental patterns of science identity across 4 years of college were examined using growth-mixture modeling. Gender, race/ethnicity, and competence beliefs (efficacy for science tasks, perceived competence in science) were modeled as antecedents, and participation in a science career after graduation was modeled as a distal outcome of these identity development trajectories. Three latent classes (High with Transitory Incline, Moderate-High and Stable, and Moderate-Low with Early Decline) were identified. Gender, race/ethnicity, and competence beliefs in the first year of college significantly predicted latent class membership. In addition, students in the two highest classes were significantly more likely to report being involved in science careers or science fields after college graduation than students in the Moderate-Low with Early Decline class.

Peer influence processes as mediators of effects of a middle school substance use prevention program.

BACKGROUND: Peer influence processes have been linked to escalation in substance use during the middle school years, particularly among at-risk youth. In this study, we report on an approach to prevention that attempts to counteract peer influence by interrupting the process of deviant peer clustering, in which socially marginalized youth self-aggregate and reinforce delinquent behavior, including substance use. We aimed to interrupt this process by implementing collaborative, group-based learning activities in school (i.e., cooperative learning). METHODS: In a cluster randomized trial in the Pacific Northwest (N = 1460 7th-grade students in 15 schools), we tested whether cooperative learning can reduce alcohol and tobacco use, and whether these effects are mediated by reductions in the amount of alcohol and tobacco use among one's friends. Intervention schools were provided with training in cooperative learning, and data were collected in September/October 2016 (baseline) and March 2017 (follow-up). RESULTS: Results indicated that cooperative learning significantly lowered rates of growth in alcohol (ß = -0.60 [-0.36|-0.84]; p < .001) and tobacco use (ß = -0.58 [-0.21|-0.94]; p = .01) between baseline and follow-up in intervention schools as compared to control schools. These effects were mediated by reductions in the prevalence of alcohol and tobacco use, respectively, among self-selected friends. CONCLUSIONS: Cooperative learning was able to significantly reduce the prevalence of both alcohol and tobacco use in friendship networks during the school year. The lower prevalence of alcohol and tobacco use among friends, in turn, reduced individual use at follow-up. This study was registered as trial NCT03119415 in ClinicalTrials.gov.

Enlisting Peer Cooperation in the Service of Alcohol Use Prevention in Middle School.

This article reports on a cluster randomized trial of cooperative learning (CL) as a way to prevent escalation in alcohol use during middle school (N = 1,460 seventh-grade students, age 12-13, seven intervention and eight control schools). We hypothesized that CL, by bringing students together in group-based learning activities using positive interdependence, would interrupt the process of deviant peer clustering, provide at-risk youth with prosocial influences, and in turn, reduce escalations in alcohol use. Results indicated that CL significantly reduced growth in deviant peer affiliation and actual alcohol use, and effects for willingness to use alcohol were at the threshold of significance (p = .05). CL also attenuated the link between willingness to use alcohol and later alcohol use.

Cooperative Learning in Middle School: A Means to Improve Peer Relations and Reduce Victimization, Bullying, and Related Outcomes.

Peer victimization is a highly stressful experience that impacts up to a third of all adolescents and can contribute to a variety of negative outcomes, including elevated anxiety, depression, drug use, and delinquency, as well as reduced self-esteem, school attendance, and academic achievement. Current prevention approaches (e.g., the Olweus program) have a mixed record in American schools. We propose a new approach to prevention that leverages theory and research surrounding the social aspects of bullying and victimization, particularly peer relations. Our approach attempts to (1) break down the process of homophily among bullies, and (2) provide a mechanism by which socially isolated students can develop new friendships. Our approach asks teachers to increase opportunities for positive peer interaction through carefully structured, group-based learning activities in school (i.e., cooperative learning). We hypothesized that these positive peer interactions would result in reductions in bullying, victimization, perceived stress, and emotional problems, as well as increases in peer relatedness, among more marginalized students. Using a cluster randomized trial with 15 rural middle schools in the Pacific Northwest (N = 1,460 7th grade students), we found that cooperative learning significantly reduced bullying, victimization, and perceived stress for marginalized students (i.e., moderated effects), and reduced emotional problems and enhanced relatedness for all students (i.e., main effects). Given that cooperative learning has already been shown to enhance student engagement and achievement in prior research, our results demonstrate that cooperative learning can be a permanent, sustainable component of teacher training and school culture.

A component-centered meta-analysis of family-based prevention programs for adolescent substance use.

Although research has documented the positive effects of family-based prevention programs, the field lacks specific information regarding why these programs are effective. The current study summarized the effects of family-based programs on adolescent substance use using a component-based approach to meta-analysis in which we decomposed programs into a set of key topics or components that were specifically addressed by program curricula (e.g., parental monitoring/behavior management,problem solving, positive family relations, etc.). Components were coded according to the amount of time spent on program services that targeted youth, parents, and the whole family; we also coded effect sizes across studies for each substance-related outcome. Given the nested nature of the data, we used hierarchical linear modeling to link program components (Level 2) with effect sizes (Level 1). The overall effect size across programs was .31, which did not differ by type of substance. Youth-focused components designed to encourage more positive family relationships and a positive orientation toward the future emerged as key factors predicting larger than average effect sizes. Our results suggest that, within the universe of family-based prevention, where components such as parental monitoring/behavior management are almost universal, adding or expanding certain youth-focused components may be able to enhance program efficacy.

Human cadavers Vs. multimedia simulation: A study of student learning in anatomy.

Multimedia and simulation programs are increasingly being used for anatomy instruction, yet it remains unclear how learning with these technologies compares with learning with actual human cadavers. Using a multilevel, quasi-experimental-control design, this study compared the effects of "Anatomy and Physiology Revealed" (APR) multimedia learning system with a traditional undergraduate human cadaver laboratory. APR is a model-based multimedia simulation tool that uses high-resolution pictures to construct a prosected cadaver. APR also provides animations showing the function of specific anatomical structures. Results showed that the human cadaver laboratory offered a significant advantage over the multimedia simulation program on cadaver-based measures of identification and explanatory knowledge. These findings reinforce concerns that incorporating multimedia simulation into anatomy instruction requires careful alignment between learning tasks and performance measures. Findings also imply that additional pedagogical strategies are needed to support transfer from simulated to real-world application of anatomical knowledge.

Competition and performance: more facts, more understanding? Comment on Murayama and Elliot (2012).

Murayama and Elliot (2012) made a significant contribution to the literature on competition by presenting the results of 2 meta-analyses and 3 primary studies on the relation between competition and performance. Murayama and Elliot established that in general, there is no relationship between competition and performance. They then made the case that the lack of relationship is due to 2 opposing processes (performance-approach and performance-avoidance goals) that cancel each other out. The meta-analyses made a significant contribution to the literature on competition but had problems with the way in which the types of competition were defined and the clarity of the control condition. Their opposing processes model suffers from the relatively high relationship between performance-approach and performance-avoidance goals, their failure to include likelihood of success or failure in their model, and the lack of specification of the process through which competition prompts one type of goal or the other. Their results do highlight the need for further research on competition focusing on the combination of personality traits and situational variables.

Early literacy individual growth and development indicators (EL-IGDIs): growth trajectories using a large, internet-based sample.

Early literacy individual growth and development indicators (EL-IGDIs) assess preschoolers' expressive vocabulary development and phonological awareness. This study investigated longitudinal change in EL-IGDIs using a large (N=7355), internet-based sample of 36- to 60-month-old United States preschoolers without identified risks for later achievement delays. There were three major findings. First, results identified sensitivity to longitudinal change for all three EL-IGDIs (i.e., Picture naming, Rhyming, and Alliteration). Second, results demonstrated age-related differences in growth rates between 3- and 4-year-olds, especially for Rhyming and Alliteration. Third, preliminary national norms were reported. Discussion highlights the need for research examining the sensitivity of EL-IGDIs for younger preschoolers.

Autonomy, belongingness, and engagement in school as contributors to adolescent psychological well-being.

Self-determination theory emphasizes the importance of school-based autonomy and belongingness to academic achievement and psychological adjustment, and the theory posits a model in which engagement in school mediates the influence of autonomy and belongingness on these outcomes. To date, this model has only been evaluated on academic outcomes. Utilizing short-term longitudinal data (5-month timeframe) from a set of secondary schools in the rural Midwest (N = 283, M age = 15.3, 51.9% male, 86.2% White), we extend the model to include a measure of positive adjustment (i.e., hope). We also find a direct link between peer-related belongingness (i.e., peer support) and positive adjustment that is not mediated by engagement in school. A reciprocal relationship between academic autonomy, teacher-related belongingness (i.e., teacher support) and engagement in learning is supported, but this reciprocal relationship does not extend to peer-related belongingness. The implications of these findings for secondary schools are discussed.

Promoting early adolescents' achievement and peer relationships: the effects of cooperative, competitive, and individualistic goal structures.

Emphasizing the developmental need for positive peer relationships, in this study the authors tested a social-contextual view of the mechanisms and processes by which early adolescents' achievement and peer relationships may be promoted simultaneously. Meta-analysis was used to review 148 independent studies comparing the relative effectiveness of cooperative, competitive, and individualistic goal structures in promoting early adolescents' achievement and positive peer relationships. These studies represented over 8 decades of research on over 17,000 early adolescents from 11 countries and 4 multinational samples. As predicted by social interdependence theory, results indicate that higher achievement and more positive peer relationships were associated with cooperative rather than competitive or individualistic goal structures. Also as predicted, results show that cooperative goal structures were associated with a positive relation between achievement and positive peer relationships. Implications for theory and application are discussed.
