For three decades, social cognitive researchers have studied children's development of self-regulation as an achievement of socialization processes. I recount historically the emergence of a social cognitive perspective on self-regulation and identify its unique features. Two essential characteristics of students' self-regulated academic learning have been identified — their use of strategies and perceptions of self-efficacy. A social cognitive model of academic self-regulated learning is proposed that integrates triadic determinants of self-regulated learning (personal, behavioral, and environmental) on the basis of a strategic control loop. When students monitor their responding and attribute outcomes to their strategies, their learning becomes self-regulated, and they display increased self-efficacy, greater intrinsic motivation, and higher academic achievement.  相似文献

This study examines sources of satisfaction, indicators of stress, academic performance, and reward structure in the academic careers of male and female faculty at a major midwestern state university. Faculty pairs were selected from five academic divisions. A total of 58 matched pairs were identified. Of these, 63 faculty responded, yielding data for 23 matched pairs. Subjects were mailed the Academic Career Development Survey, consisting of 144 items. Results indicated that self-reported physical and mental health, and professional and personal life satisfaction were high for both males and females. Both males and females placed high importance on their career and on marriage/other intimate relationships; however, both reported high levels of dissatisfaction with these factors. Gender differences were found in both satisfaction and type of stress reported; no gender differences were found in composite teaching and research performance indices. Salary data, obtained for 42 matched pairs, indicated similar salary levels for men and women. Results were discussed with respect to prior research on gender differences and the academic career.  相似文献

This article reports the results of research to determine if a significant interactive effect exists between students' lingual background (English as a primary language [EPL] versus English as a secondary language [ESL]) and question format on students' examination scores. Students were administered examinations made up of four subtests covering the same subject matter. The subtests were composed of four question formats: multiple choice quantitative, multiple choice theoretical, open-ended quantitative, and open-ended essay questions. Based on analysis of variance and analysis of covariance, significant differences were observed between EPL and ESL students depending on the type of question on the examination.  相似文献

Markets,inequality, and urban schooling   总被引:1,自引:0,他引:1  
This paper considers the intellectual and political antecedents of current attempts by the British government to create a market in state education. The implications of market forces for school organization, educational values, teachers' careers and conditions of work, and equality and social justice in the inner city are also explored. It is argued that policies of competition between per capita funded schools are likely to increase the existing inequalities in school provision in England to the disadvantage of children in urban areas.  相似文献

This study assessed the influence of individual family members in functional families, primarily to determine whether hearing children of deaf parents have more influence than do hearing children of hearing parents. Eight families with deaf parents and a hearing child and eight all hearing families were videotaped while planning a family meal together. It was found that deaf-parented families share many traits with hearing families. However, there were some differences. The hearing children of deaf parents had a greater number and percentage of their ideas accepted than did the hearing children of hearing parents. Differences were also noted between the deaf fathers and the hearing fathers. The deaf-parented families were more adaptable, as measured by the Family Adaptability and Cohesion Evaluation Scale. The observed difference in child influence, in and of itself, is neither good nor bad. Deafness of one family member, in an auditory dependent environment, may require a more flexible family power structure. Professionals assessing deaf-parented families should be sensitive to the special adaptive needs required for healthy functioning of the family.  相似文献

This study evaluated the emotional and marital adjustment of hearing parents of hearing-impaired youths. Participants included mothers and fathers of hearing-impaired youths and mothers and fathers of hearing youths. In contrast with expectations based on clinical impressions reported in the literature, parents of hearing-impaired youths reported less symptomatology than did parents of hearing youths, and there were no differences in the marital satisfaction of parents in intact families. Moreover, parental adjustment was not associated with the duration of time since the child was diagnosed as hearing impaired. In addition, hierarchical multiple regression analyses revealed that family cohesion was associated with low maternal symptomatology and high marital satisfaction for both spouses. For mothers, low symptomatology was associated with low stress and female gender of child; high marital satisfaction also was linked with a less severe degree of hearing loss in the youth.  相似文献

In a widely cited study, Matas, Arend, and Sroufe showed that mother-toddler interaction during problem solving at age 2 years was related to the child's prior attachment security. The current study asked (1) whether an independent laboratory could replicate this attachment finding, and (2) whether problem-solving interactions relate to mother-child interactions observed at home and to child temperament measured at 6, 13, and 24 months. Replicating Matas et al., secure dyads worked more competently, and mothers showed better quality of assistance and supportive presence. Mother-child home interaction also predicted problem solving: positive involvement at home predicted effective, unconflicted problem solving. Negative control at home did not predict problem-solving interaction. Unadaptable temperament was generally related to dependency in problem solving. Several patterns of correlations appeared to be mediated by sex of child, e.g., difficult temperament in boys predicted more effective, unconflicted problem solving, while for girls it predicted more conflict.  相似文献

The incidence of human immunodeficiency virus (HIV) infection acquired by children through sexual abuse is presently unknown. A telephone survey of 63 practitioners of pediatric sexual abuse (PSA) assessment in the five U.S. regions with highest prevalence of HIV infection was conducted to determine the present status of guidelines for HIV antibody testing of PSA victims. No formal protocol was used by any of those surveyed, and a literature review found no existing guidelines for HIV antibody testing of PSA victims. A standard set of clinical situations was presented to practitioners to assess whether a consensus exists of indications for HIV antibody testing of abused children. Seven clinical profiles with 12 criteria were presented including HIV antibody status, AIDS/ARC clinical profile, and behavioral profile of the assailant; clinical profile of the victim; pre-assault victim behavioral profile compatible with high risk of HIV infection (exclusively adolescents); parent/guardian anxiety/psychosocial profile; and profile of the assaultive act with respect to potential transmissibility of HIV. We found an 85% or greater consensus for 6 testing criteria, and based upon these propose an interim set of HIV antibody testing guidelines for PSA victims. There was no consensus about five testing criteria, but their frequent citation merits further consideration. Clinical application of interim guidelines and design of prospective studies to quantitatively evaluate them are reviewed.  相似文献
