This study investigated the relations between early adolescents’ academic motivational orientations and an aspect of quality of friendship: intimacy. Two-hundred and three Jewish-Israeli seventh grade students responded to surveys asking them about their academic achievement goals and about characteristics of their friendships. Variable-centered regression analyses suggested that mastery goals were positively associated with mutual sharing of difficulties, trust, and adaptive social problem-solving between friends, whereas performance-approach goals were negatively associated with intimacy friendship. Moreover, both performance-approach and performance-avoidance goals were associated with mistrust, inconsideration, and tension between friends. A person-centered analysis, employing cluster analysis, suggested that profiles with a higher level of mastery goals relative to both types of performance goals were associated with less mistrust among friends in comparison with profiles with a higher level of performance goals relative to mastery goals. The findings point to the connection between academic motivation and social relationships in school. 相似文献

This article examines Bayesian model averaging as a means of addressing predictive performance in Bayesian structural equation models. The current approach to addressing the problem of model uncertainty lies in the method of Bayesian model averaging. We expand the work of Madigan and his colleagues by considering a structural equation model as a special case of a directed acyclic graph. We then provide an algorithm that searches the model space for submodels and obtains a weighted average of the submodels using posterior model probabilities as weights. Our simulation study provides a frequentist evaluation of our Bayesian model averaging approach and indicates that when the true model is known, Bayesian model averaging does not yield necessarily better predictive performance compared to nonaveraged models. However, our case study using data from an international large-scale assessment reveals that the model-averaged submodels provide better posterior predictive performance compared to the initially specified model. 相似文献

Physical abuse during adolescence: Gender differences in the adolescents' perceptions of family functioning and parenting 总被引:2,自引:0,他引:2
OBJECTIVE: To examine the relationship between physical abuse of adolescents and parenting by mothers and fathers and whether the association differs by gender. METHODS: Subjects were adolescents, 51 girls and 45 boys, documented by Child Protective Services (CPS) as physically abused during adolescence. Comparison subjects were non-abused adolescents, 47 girls and 48 boys, from the same suburban communities. Subjects completed the following: Family Adaptability and Cohesion Evaluation Scale, Parental Bonding Instrument, modified Conflict Tactics Scale (assessing physical abuse/punishment by each parent). RESULTS: Although CPS generally cited fathers as the abuse perpetrators, abused boys and girls often reported experiencing physical maltreatment from both parents. Not surprisingly, comparison subjects rated parents more positively than abused subjects. For both groups, mothers were perceived as more caring and less controlling, were reported to have closer relationships with their adolescents, and were less likely to use abuse/harsh punishment than were fathers. Differences between the adolescents' perceptions of mothers and fathers were more pronounced for abused than for comparison subjects. Boys' and girls' perceptions of parenting were generally similar except that girls, especially the abused girls, reported feeling less close to fathers. Abused girls also viewed mothers as less caring than the other groups viewed mothers. Abused girls were also less likely than abused boys to perceive that either parent, but particularly fathers, had provided them with an optimum style of parenting. CONCLUSIONS: Adolescents who experienced relatively mild physical abuse reported dysfunctional family relationships, which may place them at risk of poor adult outcomes. Adolescents' reports suggest that CPS reports may underestimate physical maltreatment by mothers. 相似文献

Conceptually, practically and rhetorically teaching is at the core of quality in higher education. University teaching preparation programmes (TPPs) are regularly advocated to foster enhancement of teaching but there remains limited evidence to demonstrate their effectiveness or impact as a quality improvement mechanism. Support for such programmes is largely a matter of faith amongst their advocates. This paper presents an analysis of the impact of one initial TPP to add to the body of evidence on the efficacy of such programmes. The results reinforce other research indicating that such programmes do have beneficial effects on individual academics. The benefits extend to work groups and have value to the institution. However, the transfer of learning by academics to practice takes time and is mediated by many factors. Nevertheless, where institutional and local departmental cultures value teaching, TPPs provide a useful strategy for quality enhancement in higher education. 相似文献

This article discusses a question‐led approach to the design of a new degree programme in computing and information studies, the Bachelor of Informatics, at Griffith University in Brisbane, Australia. Basic considerations arising from various theories which have given a central place to problems and questions in human activity are outlined. Some implications of these considerations for the role and place of questions in education are discussed in terms of the notions of focussing, opening, and activating. It is argued that these notions are important in understanding education to be, in part, vitally concerned with critical inquiry. The specific context at Griffith University in which the question‐led approach came to be adopted is described, together with an account of a report concerning the planning of a new academic activity in the University which was made available to the planning group at the commencement of planning. The processes by which this approach was implemented in the design phase are described briefly. The resulting design, as it existed shortly prior to the commencement of teaching, is described. The conclusion discusses some issues arising from experience in the design and implementation of this programme, and provides some evaluative feedback from staff and second‐year students obtained during the second year during which the programme was offered (1986). 相似文献

OBJECTIVE: The present study describes factors related to fatal abuse in three age groups in the United States Air Force (USAF). METHOD: Records from 32 substantiated cases of fatal child abuse in the USAF were independently reviewed for 60 predefined factors. RESULTS: Males were over-represented in young child victims (between 1 year and 4 years of age) and child victims (between 4 years and 15 years of age) but not in infant victims (between 24 hours and 1 year of age). African-American infant victims and perpetrators were over-represented. Younger victims were more likely to have been previously physically abused by the perpetrator. Perpetrators were predominantly male and the biological fathers of the victims. Infant and young child perpetrators reported childhood abuse histories, while child perpetrators reported the highest frequency of mental health contact. Victims' families reported significant life stressors. Families of young child victims were more likely divorced, separated, or single. Incidents with infants and young children tended to occur without witnesses; incidents with child victims tended to have the victim's sibling(s) and/or mother present. Fatal incidents were more frequent on the weekend, in the home, and initiated by some family disturbance. CONCLUSIONS: Differences among groups in factors related to infant and child homicide across age groups may assist in the development of more tailored abuse prevention efforts and may also guide future investigations. 相似文献

A mixed analysis of the perceived characteristics of effective college faculty members was conducted through surveying 615 students, predominantly Hispanic, enrolled in courses at two southwest Hispanic‐serving universities. Beliefs were identified that led to 29 prevailing themes: Knowledgeable; Understanding; Communication; Teaches Well; Caring; Organised; Flexibility; Positive Attitude; Patience; Experience in the Classroom; Fair; Helping; Respectful; Open‐minded; Builds Relationships; Passion for the Job; Service; Makes Learning Interesting; Uses Different Modalities; Fun; Motivating; Intelligent; Involving Students; Being Available; Friendly; Connects with the Real World; Listening; Creativity; and Challenges Student. Of these themes, knowledgeable, Understanding, Communication and Teaches Well received the highest endorsements and are congruent with student evaluations that are components of promotion and tenure decisions. 相似文献

The impacts of New Hope, a 3-year work-based antipoverty program to increase parent employment and reduce poverty, on youth ages 9-19 (N = 866) were assessed 5 years after parents left the program. New Hope had positive effects on the future orientation and employment experiences of boys, especially African American boys. Compared to boys in control group families, boys in program group families were less cynical about work, less pessimistic about their employment prospects, and more involved in employment and career preparation. They also worked for longer periods during the school year than did control group boys. Comparable effects were not found for girls. The developmental significance of the findings, possible processes that led to the impacts, and the policy implications of the findings are discussed. 相似文献
