Family,peer, and neighborhood influences on academic achievement among African-American adolescents: One-year prospective effects

Using a 1-year prospective design, this study examined the influence of family status variables (family income, parental education, family structure), parenting variables (maternal support and restrictive control), peer support, and neighborhood risk on the school performance of 120 African American junior high school students. In addition to main effects of these variables, neighborhood risk was examined as a moderator of the effects of parenting and peer support. Family status variables were not predictive of adolescent school performance as indexed by self-reported grade point average. Maternal support at Time 1 was prospectively related to adolescent grades at Time 2. Neighborhood risk was related to lower grades, while peer support predicted better grades in the prospective analyses. Neighborhood risk also moderated the effects of maternal restrictive control and peer support on adolescent grades in prospective analyses. These findings highlight the importance of an ecological approach to the problem of academic underachievement within the African American community.     

Collaborative learning in engineering ethics

This paper discusses collaborative learning and its use in an elective course on ethics in engineering. Collaborative learning is a form of active learning in which students learn with and from one another in small groups. The benefits of collaborative learning include improved student performance and enthusiasm for learning, development of communication skills, and greater student appreciation of the importance of judgment and collaboration in solving real-world problems such as those encountered in engineering ethics. Collaborative learning strategies employed in the course include informal small group discussions/problem solving, role-playing exercises, and cooperative student group projects, including peer grading. Student response to these techniques has been highly favorable. Realizing the benefits of collaborative learning is a challenge to both teachers, who must give up some control in the classroom, and students, who must be willing to take greater responsibility for their learning. An earlier version of this paper was presented by the author at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9, 1997 The author teaches courses in Science, Technology and Society and is Director of the Benjamin Franklin Scholars Program, a dual-degree program in engineering and humanities/social sciences.     

Peer review for journals: Evidence on quality control, fairness, and innovation

This paper reviews the published empirical evidence concerning journal peer review consisting of 68 papers, all but three published since 1975. Peer review improves quality, but its use to screen papers has met with limited success. Current procedures to assure quality and fairness seem to discourage scientific advancement, especially important innovations, because findings that conflict with current beliefs are often judged to have defects. Editors can use procedures to encourage the publication of papers with innovative findings such as invited papers, early-acceptance procedures, author nominations of reviewers, structured rating sheets, open peer review, results-blind review, and, in particular, electronic publication. Some journals are currently using these procedures. The basic principle behind the proposals is to change the decision from whether to publish a paper to how to publish it. The author, a professor of marketing at the Wharton School since 1968, was a founder editor of the Journal of Forecasting and the International Journal of Forecasting. This paper is based on a presentation at a workshop, “Advances in Peer Review Research”, American Association for the Advancement of Science Meeting, Baltimore, MD, February 9, 1996.     

Retention and treatment failure in Classwide Peer Tutoring: Implications for further research

Knowledge of basic arithmetic facts aids in the acquisition and speed of performance of arithmetic operations. A peer mediated instructional procedure, Classwide Peer Tutoring (CWPT), has been shown to increase the rates and accuracy of students responses to academic tasks and to improve student performance on a variety of academic tasks. The present investigation evaluated the retention of 100 subtraction items by primary grade-age children with mild disabilities using CWPT for 10 weeks. Short- and long-term retention of items, and rate of correct responding were assessed. Results indicated that the students' average pretest score was 58.0% correct, and their average weekly posttest score was 87.12 correct, a 27% improvement in accuracy. Short- and longer-term retention measured on posttests was 88.7 % and 85.0% correct, respectively. Improvement in students rate of accurate responding to subtraction items practiced during CWPT was obtained. Student failure to learn particular items was not attributable to fewer opportunities to practice these items, less accurate practice, or item difficulty. Students reported positive evaluation of CWPT and perceived positive social and self esteem outcomes. Directions for future research focusing on retention and analysis of treatment failure are suggested.     

Peer networks and bullying in schools

This study looked at how the social constellations in school classes relate to bullying problems. Using peer-evaluation questionnaires, the peer networks of children with different participant roles (such as victim, bully, assistant of bully, reinforcer of bully, defender of victim, outsider) were explored. The subjects were 459 sixth-grade-children (218 girls, 241 boys), aged 11 to 12 years, in Finland. The main findings were: 1) Children who tended to behave in either similar or complementary participant roles in situations of bullying formed networks with each other. The individual child's behavior in bullying situations was strongly connected to how the members of his/her network behaved in such situations. 2) Bullies, assistants, and reinforcers belonged to larger networks than did defenders, outsiders and victims. 3) Children outside the networks were most often victims. It was concluded that behavior in bullying situations can be said to be one feature around which the peer networks in school classes are organized. Thus prevention, as well as intervention strategies against bullying should focus not only on individual children, but also on the wider social context of the class.     

Comparability of peer-assessment measures: A multitrait-multimethod and selection analytic approach

This research attempted to assess the relationship among the Pupil Evaluation Inventory (PEI), sociometric nominations, and sociometric ratings in terms of (1) a multitrait-multimethod analysis, (2) selection agreement indices of extreme individuals, and (3) stability over an 8-week period. Subjects were members of four second-grade classrooms at a regional school serving a diverse population of children. While stability estimates for measures were adequate and evidence for convergent validity was reasonably good, evidence for divergent validity was weaker. Selection agreement analyses yielded highly variable results, indicating that different samples of children tend to be selected by different instruments despite the similarity in dimensions being tapped. Methodological and theoretical implications of these findings are discussed.This work was based on the first author's M.S. thesis under the direction of the second author.     

初中生同伴圈子的发展及其对合作倾向、预期和行为的影响

在社会化过程中,同伴圈子不仅决定儿童青少年的交往范围和互动质量,而且影响其心理发展和社会适应。本研究从苏州市某初级中学选取768名初一学生进行了为期一年的追踪,采用社会认知地图、合作倾向评定量表和公共物品困境实验范式测查了同伴圈子、合作倾向、预期与合作行为,运用多层线性模型技术（Two-level HLM）探讨同伴圈子的合作水平对个体合作水平的影响。结果发现：（1）女生圈子数量最多而规模最小,男女混合圈子规模最大而数量最少;跨地域圈子数量最多且规模最大;（2）女生圈子最为稳定,男女混合圈子最不稳定;（3）在混合性别圈子中,个体的合作预期与行为更容易随着圈子合作预期水平的提高而增强;而在单性别圈子中,个体的合作预期与行为更容易随着圈子合作行为水平的提高而增强。结论：初中生同伴圈子在性别上具有同质性,女生圈子多且稳定;第一年单性别和混合性别圈子的合作倾向、预期和行为水平对第二年个体的合作水平产生了不同影响,即不同性别圈子对个体的影响模式存在差异。     

Religiosity Reduces Sexual Aggression and Coercion in a Longitudinal Cohort of College Men: Mediating Roles of Peer Norms,Promiscuity, and Pornography

Extensive literature suggests that religiosity is a protective factor in reducing a number of deviant behaviors, including sexual aggression (SA). Whereas previous research focused on the role of risky alcohol consumption in mediating the relationship between religiosity and SA, this study explores the hypothesized meditational paths from religiosity to SA and technology‐based coercive behavior (TBC) through peer norms, pornography consumption, and promiscuity. Findings from a four‐year longitudinal study of male college students suggest that peer norms and promiscuity mediate the relationship between religiosity and both outcome measures, while pornography consumption mediates the relationship between religiosity and TBC. These findings may inform ongoing practice and future research into possible mechanisms by which problematic sexual behaviors may be influenced.     

Transitions in sleep problems from late adolescence to young adulthood: A longitudinal analysis of the effects of peer victimization

Adolescence is a developmental period with high vulnerability to sleep problems. However, research identifying distinct patterns and underlying determinants of sleep problems is scarce. This study investigated discrete subgroups of, changes in, and stability of sleep problems. We also examined whether peer victimization influenced sleep problem subgroups and transitions in patterns of sleep problems from late adolescence to young adulthood. Sex differences in the effects of peer victimization were also explored. In total, 1,455 male and 1,399 female adolescents from northern Taiwan participated in this longitudinal study. Latent transition analysis was used to examine changes in patterns of sleep problems and the effects of peer victimization on these changes. We identified three subgroups of sleep problems in males and two in females, and found that there was a certain level of instability in patterns of sleep problems during the study period. For both sexes, those with greater increases in peer victimization over time were more likely to change from being a good sleeper to a poor sleeper. The effects of peer victimization on baseline status of sleep problems, however, was only significant for males, with those exposed to higher levels of peer victimization more likely to be poor sleepers at baseline. Our findings reveal an important role of peer victimization in predicting transitions in patterns of sleep problems. Intervention programs aimed at decreasing peer victimization may help reduce the development and escalation of sleep problems among adolescents, especially in males.
