The predictive value of school climate and teacher techniques on students’ just world beliefs: a comprehensive Brazilian sample

Substantial research has established the connection between students’ beliefs in a just world (BJW) and their perceptions of and behaviors in the school. While much of that research has acknowledged that the relationship between BJW and school variables must be bi-directional, little empirical evidence exists on how the school climate shapes students’ perceptions of justice. This study draws from a comprehensive sample of Brazilian students from third through twelfth grade (n = 18,514) across 122 public schools in Southern Brazil. Results reveal that school climate variables account for 12.1–19.6% of the variance of students’ BJW, with middle school being a time of strongest influence. Perceptions of rule fairness, student–student relationships, and positive and socio-emotional learning techniques were significant predictors across all grade levels. Additional analyses revealed that teachers’ positive and socio-emotional techniques can act as a moderator between school climate and students’ BJW. The results provide more tangible ways to integrate just world research into the educational context by bridging the gap between school climate research and just world theory. This study provides empirical data for the bidirectionality of BJW and school context and opens the discussion on how the school sets students’ future expectations of justice

Changes in Character Virtues are Driven by Classroom Relationships: A Longitudinal Study of Elementary School Children

The purpose of this study is to understand the role of school relationships in shaping students’ character development in middle childhood. Students and teachers completed surveys on student–teacher relationships, peer relationships, social-emotional learning (SEL), parent-teacher communication, and character strengths of fairness, hope, bravery, teamwork, self-regulation, social responsibility, and prosocial leadership. Participants were 1881 Brazilian children in fourth or fifth grade across 288 classrooms and 60 schools. Data were analyzed using a multi-level model framework. Higher student–student relationships were associated with higher starting scores of character strengths paired with a stronger increase among classes whose relationships improved over time. Higher quality student–teacher relationships were associated with a larger increase in character strengths among boys. Teachers’ usage of SEL strategies, student–teacher relationships and student peer relationships were important predictors of both classroom baselines and the change in character strengths across time. Most of the existing literature on character strengths is based on older adolescent samples from affluent countries and with little Latin American representation. This study supports existing literature on the relevancy of character strengths in the educational context, but adds the importance of seeing it as a contextual and relational outcome

Just environments foster character: A longitudinal assessment of school climate

Justice is at the center of many definitions of character across various lines of research, yet there is little empirical research on how the justice of contexts can foster character virtues. The current study draws from a sample of 1,865 Brazilian fourth and fifth graders across two time points in 60 schools (42.7% White; 48.3% male). A multilevel structural equation model demonstrated the mediating role that justice beliefs play between authoritative school climate and socio-emotional learning, and the character virtues of bravery, fairness, and prosocial leadership even after accounting for grade, gender, ethnicity, and socioeconomic status (SES). This study highlights the importance of understanding the contextual justice of children’s environments on the development of character virtues

Manipulating insulin signaling to enhance mosquito reproduction

<p>Abstract</p> <p>Backgrond</p> <p>In the mosquito <it>Aedes aegypti </it>the insulin/insulin growth factor I signaling (IIS) cascade is a key regulator of many physiological processes, including reproduction. Two important reproductive events, steroidogenesis in the ovary and yolk synthesis in the fat body, are regulated by the IIS cascade in mosquitoes. The signaling molecule phosphatase and tensin homolog (PTEN) is a key inhibitor of the IIS cascade that helps modulate the activity of the IIS cascade. In <it>Ae. aegypti</it>, six unique splice variants of AaegPTEN were previously identified, but the role of these splice variants, particularly AaegPTEN3 and 6, were unknown.</p> <p>Results</p> <p>Knockdown of AaegPTEN or its specific splice variant AaegPTEN6 (the splice variant thought to regulate reproduction in the ovary and fat body) using RNAi led to a 15–63% increase in egg production with no adverse effects on egg viability during the first reproductive cycle. Knockdown of AaegPTEN3, expressed predominantly in the head, had no effect on reproduction. We also characterized the protein expression patterns of these two splice variants during development and in various tissues during a reproductive cycle.</p> <p>Conclusion</p> <p>Previous studies in a range of organisms, including <it>Drosophila melanogaster </it>and <it>Caenorhabditis elegans</it>, have demonstrated that disruption of the IIS cascade leads to decreased reproduction or sterility. In this study we demonstrate that knockdown of the IIS inhibitor PTEN can actually increase reproduction in the mosquito, at least during the first reproductive cycle.</p

Socially responsible children: A link between school climate and aggression and victimization

Positive perceptions of school climate are associated with lower frequency of peer victimization and aggression in children. Understanding how school climate influences aggression and victimization is essential to guiding school-level interventions to enhance character strengths such as social responsibility. In this short-term longitudinal study, we test a theoretical model arguing that children’s social responsibility mediates the links between their positive perceptions of school climate (comprised of authoritative disciplinary classroom structure, classroom support, and teachers’ use of social–emotional learning [SEL] strategies) and changes in their reports of victimization and aggression, in a sample of Brazilian students in Grades 4 and 5 (N = 1,850). Findings gave some support to our model, particularly in the prediction of aggression. Children’s perceived social responsibility mediated the effects of positive school climate in predicting declines in aggressive behaviors. Specifically, teachers’ use of SEL strategies and classrooms with more structure and support predicted lower levels of aggression through increases in students’ social responsibility. In addition, social responsibility mediated the association between teachers’ use of social emotional strategies and declines in victimization. The direct effect of classroom support on victimization was also significant

Fairness, trust, and school climate as foundational to growth mindset: A study among Brazilian children and adolescents

Recent research has established the importance of children and adolescents developing a growth mindset for future success and motivation. This research tests believes about fairness, adult trust, and school climate that are theoretically foundational for establishing a cognitive connection between effort and outcome. Regressions and MANOVAS were conducted to understand the direct and indirect relationships between perceptions of justice, adult trust, school climate and growth mindsets. The first study included 363 children from Brazilian public schools and the findings supported our hypothesis that adult trust partially mediates the relationship between justice perceptions and growth mindset. The second study included an adolescent sample (n = 497) from more diverse backgrounds and included a measure of institutional mindset. In this study, school fairness and solidarity mediated the relationship between perceptions of justice on institutional growth mindset. This research can help inform educators and researchers of other constructs necessary to foster a growth mindset

National 4-H Common Measures: Initial Evaluation from California 4-H

Evaluation is a key component to learning about the effectiveness of a program. This article provides descriptive statistics of the newly developed National 4-H Common Measures (science, healthy living, citizenship, and youth development) based on data from 721 California 4-H youth. The measures were evaluated for their reliability and validity of individual items and overall measures using exploratory factor analysis. The measures overall appear to assess what they are intended to assess, but there are several methodological issues, such as cross-loading items and low variance. Recommendations for scale refinement and modifications are made

Assessing and Teaching Critical Thinking in Communication Science and Disorders

Critical thinking is considered to be an important aspect in the training of communication science and disorders students. This paper provides information on the definition, assessment, and teaching of critical thinking. Important critical thinking skills and dispositions include challenging assumptions underlying statements, recognizing the effect of context on perceptions, understandings, and interpretations of the world, developing alternative explanations for observed data they observe, and exhibiting reflective skepticism. Increasing these skills and dispositions help a student develop into a skilled clinician. Assessing students’ clinical thinking skills can be done with tests of general skills, but these often lack validity and reliability. Assessments also can test content or discipline specific thinking skills. Teaching critical skills and dispositions has been done in stand-alone courses and as material embedded within other courses. Within the courses, techniques such as problem-based learning, team-based learning, and case presentations have been effective with mind and concept mapping as tools to visualize how the students think about the material

Direct and mediated effects of a social-emotional and character development program on adolescent substance use

Mitigating and preventing substance use among adolescents requires approaches that address the multitude of factors that influence this behavior. Such approaches must be tested, not only for evidence of empirical effectiveness, but also to determine the mechanisms by which they are successful. The aims of the present study were twofold: 1) To determine the effectiveness of a school-based social-emotional and character development (SECD) program, Positive Action (PA), in reducing substance use (SU) among a sample of U.S. youth living in a low-income, urban environment, and 2) to test one mechanism by which the program achieves its success. We used longitudinal mediation analysis to test the hypotheses that: 1) students attending PA intervention schools engage in significantly less SU than students attending control schools, 2) students attending PA intervention schools show significantly better change in SECD than students attending control schools, and 3) the effect of the PA intervention on SU is mediated by the change in SECD. Analyses revealed program effects on both SECD and SU, a relationship between SECD and SU, and the effects of PA on SU were completely mediated by changes in SECD. Future research directions and implications for schoolbased social-emotional and character development efforts and substance use prevention are addressed.peer-reviewe
