This study investigated the peer group as a context for the socialization of young adolescents' motivation and achievement in school. Social network analysis was used to identify peer groups of adolescents in middle school whose members regularly interacted with each other (N = 331). Actual reports from these peer group members were used to assess peer group characteristics. Multilevel analyses indicated that peer groups did socialize some academic characteristics, controlling for selection factors. Students' peer group context in the fall predicted changes in their liking and enjoyment of school (intrinsic value) and their achievement over the school year. Students' peer group context was unrelated to changes in their beliefs about the importance of school (utility value) or expectancies for success over the school year.  相似文献

There is increasing interest in the role of social support in determining risk for child abuse and neglect. The present study assessed the relationship between maternal social support and two areas: stress in the mother-child relationship: and level of stimulation provided in the home. Maternal social support was assessed prenatally and at a two-year follow-up, while the latter variables were compiled at the two-year follow-up. The data were obtained from 38 urban, low SES (80% on public assistance) mothers and their 2-year-old children. Maternal social support correlated positively with level of stimulation and negatively with level of mother-child stress, and was the best predictor of both, relative to any SES, mother or child variables. In addition, high stress, low support mothers provided significantly less stimulation to their children. The theoretical implications for social support as a mediator variable as well as its implications for early identification and prevention efforts in abuse and neglect are discussed.  相似文献

This paper reports the results of a study comparing college freshmen with learning disabilities (LD) and freshmen with no learning disabilities (NLD). Four data collections over one academic year were completed on a total of 72 students (LDn=39; NLDn=33). Results of the study indicated differences between groups in their initial choice of living accommodations and in the changes made over the year: the overall trend was for students with LD to become more dependent on their families, while students with NLD were becoming less dependent on their families. With regard to academics, students with LD reported spending significantly less time in study and course preparation, as well as greater pessimism about success in coursework. Despite their pessimism, the actual GPA attainment of students with LD was similar to that of NLD peers. Whereas both groups initially predicted it would be easy to adjust to the academic and social nature of college, students with learning disabilities ultimately reported being dissatisfied with the social climate on campus. No differences were found between LD and NLD students regarding their motivation for attending college, or their plans for final degree attainment.  相似文献

Tracking New Directions in the Evaluation of Postgraduate Supervision   总被引:3,自引:0,他引:3  
This article focuses on the evaluation of thesis supervision and highlights the vast range of problem areas presently documented as significant areas of concern for both graduate students and their supervisors. Additionally, the authors report on a study completed in 1995, which surveyed all Australian universities about current evaluative practices in postgraduate supervision. The conclusion of this study was that the conduct of such evaluations appears to be minimal and is primarily designed to obtain an indicator of the general health of a university's postgraduate supervision rather than to foster improved supervisory practices. As part of the same study, the authors conducted University faculty-based student and supervisor focus groups. Key issues emerging from these focus groups were: (1) the importance of relational aspects of supervision as the student communicates over the long term with one or more supervisors; (2) the importance of systematic feedback, monitoring, and evaluation to the supervisory process; and (3) the lack of strategies to facilitate this evaluative feedback process. On the basis of these findings, the authors designed evaluative strategies to facilitate regular ongoing feedback between students and supervisors.  相似文献
