Individual and Peer Characteristics in Predicting Boys' Early Onset of Substance Abuse: A Seven-Year Longitudinal Study

Early onset of substance abuse is a clear marker for future maladjustment in adolescents. The present study employed data originating from 755 6-year-old boys from low SES neighborhoods, who were followed through age 13, to predict this marker. 3 models were tested using LISREL analyses to determine whether individual characteristics and/or peer influences were linked to subsequent substance abuse. Individual characteristics consisted of fighting, hyperactivity, oppositional behaviors, and likability. Peer influences referred to mutual friends' characteristics (aggressiveness and likability). Data were obtained from 3 different sources: teacher ratings, peer ratings, and self-reports. Results were replicated at ages 10, 11, and 12 years with 3 subsamples of the original sample and indicated that individual characteristics, more than friends' deviance, are pivotal in the development of substance abuse. This finding is consistent with results from other longitudinal studies involving children from a variety of cultural backgrounds. It suggests that prevention programs should target individual characteristics and begin at an early age.     

Mathematical olympiads in the People's Republic of China

Conclusions This new series of Chinese olympiads is admittedly experimental. Chinese educators are studying the results of these contests. Building upon this acquired experience, they hope to improve and expand such competitions in the future. New standards of mathematical excellence are now being established in the PRC and future mathematical olympiads will accordingly be more demanding. It appears evident that in the near future, a team from the People's Republic of China will participate in the International Mathematical Olympiad [10].     

Community of practice versus community of readers: the literacy tutors’ dilemma

This paper describes a journey undertaken by literacy tutors who were caught between incompatible values and needs in building apprentices’ literacy. The highly literate tutors were committed to teaching critical literacy. They believed that improved literacy could support learners’ aspirations to advance their prospects at work, build their connections within their community and improve their health. Hence, the tutors aimed to guide their learners into membership of an imagined community of fluent readers. They found, however, that the apprentices, along with their managers and training coordinators, saw literacy as instrumental rather than a desired outcome in its own right. Essentially, achieving a sufficient level of literacy was needed for the apprentices to become members of workplace communities of practice. Tutors then questioned their prior assumptions about the intrinsic importance of literacy, slowly accepting a dichotomous way of thinking where industrial ways of learning and knowing were predominant. Tutors’ realisation that apprentices already possessed embodied and oral literacies helped them to support the apprentices in escaping (though not leaving) workplace contexts that were becoming increasingly document-driven in character and featuring rising expectations of improved print literacy.     

Impact of the Good Behavior Game on special education teachers

This study tested effects of a program that offers teachers universal classroom management strategies, on teachers’ burnout symptoms and self-efficacy, and their teaching behaviors. Data were collected from 147 teachers (mean age = 38.4 years, SD = 10.8) in 15 special secondary education schools for students with emotional and behavioral problems, at the start and end of the school year. Schools were randomly assigned to the experimental condition or a care-as-usual condition. Results show that the program impacted beneficially on self-reported levels of emotional exhaustion, and self-efficacy in engaging students and in classroom management, but not on teaching behaviors. Implications of this study for the professional development of teachers in special education and research are discussed.     

Construct validity of the learning behavior scale with an independent sample of students

In this study, the factor structure of the Learning Behavior Scale (LBS; McDermott, Green, Francis, & Stott, 1999) was examined in an independent sample of 257 elementary school students. The LBS is a 29‐item, four‐factor scale on which teachers rate students' positive and negative learning behaviors. The results indicated that the internal consistency of the total LBS scores and the scores on two subscales (Competence Motivation and Attitude Toward Learning) were high enough for individual decision making, whereas the reliability estimates of scores on the Attention/Persistence and Strategy/Flexibility subscales were appropriate only for research or screening purposes. Factor analyses extracted factors similar to three of the factors on the LBS (Competence Motivation, Attitude Toward Learning, and Strategy/Flexibility), and suggested that the fourth factor (Attention/Persistence) may benefit from additional study. In general, the results indicate that the LBS may be a useful tool for examining students' learning behaviors. © 2001 John Wiley & Sons, Inc.     

Developmental trajectories of externalizing behaviors in childhood and adolescence

This article describes the average and group-based developmental trajectories of aggression, opposition, property violations, and status violations using parent reports of externalizing behaviors on a longitudinal multiple birth cohort study of 2,076 children aged 4 to 18 years. Trajectories were estimated from multilevel growth curve analyses and semiparametric mixture models. Overall, males showed higher levels of externalizing behavior than did females. Aggression, opposition, and property violations decreased on average, whereas status violations increased over time. Group-based trajectories followed the shape of the average curves at different levels and were similar for males and females. The trajectories found in this study provide a basis against which deviations from the expected developmental course can be identified and classified as deviant or nondeviant.
