This study addressed the polarization among theoretical perspectives in moral psychology regarding the relative significance of parents and peers in children's developing moral maturity. The sample was composed of 60 target children from late childhood and midadolescence, 60 parents, and 60 friends who participated in parent/child and friend/child dyadic discussions of a series of moral conflicts. The quality of parents' and friends' verbal interactions, ego functioning, and level of moral reasoning in these discussions was used to predict the rate of children's moral reasoning development over a 4-year longitudinal interval. Results revealed that interactions with both parents and peers were predictive of children's development but that these two types of relationships influence development in rather different ways. Implications of the findings for the understanding of these socialization agents' roles in moral development are discussed.  相似文献

US adolescents initiate sex at increasingly younger ages, yet few pregnancy prevention interventions for children as young as 10-12 years old have been evaluated. Sixteen Washington, DC schools were randomly assigned to intervention versus control conditions. Beginning in 2001/02 with fifth-grade students and continuing during the sixth grade, students completed pre-intervention and post-intervention surveys each school year. Each year, the intervention included 10-13 classroom sessions related to delaying sexual initiation. Linear hierarchical models compared outcome changes between intervention and control groups by gender over time. Results show the intervention significantly decreased a rise over time in the anticipation of having sex in the next 12 months among intervention boys versus control boys, but it had no other outcome effects. Among girls, the intervention had no significant outcome effects. One exception is that for both genders, compared with control students, intervention students increased their pubertal knowledge. In conclusion, a school-based curriculum to delay sexual involvement among fifth-grade and sixth-grade high-risk youths had limited impact. Additional research is necessary to outline effective interventions, and more intensive, comprehensive interventions may be required to counteract adverse circumstances in students' lives and pervasive influences toward early sex.ClinicalTrials. gov identifier: NCT00341471.  相似文献

This article is the first in an occasional series in which books recently published in paperback will be introduced to readers.Cle will select titles which seem particularly suitable for school students to read together. Our intention is to choose books readily available in North America as well as countries served by British publishers. Our first selection,The Chocolate War, appeared in the USA in 1974, in the UK in 1975 and in paperback in the USA in 1975 and in the UK in February, 1978.Robbie March-Penny read English at Birmingham College of Commerce and York University. She has taught English in comprehensive schools in Birmingham and Bristol and is now an editor of children's books for a London publisher.  相似文献

The purpose of this study was to examine the relationship between supervisor perceptions of their supervisory style and elements of the supervision process, including the supervisory working alliance and supervisor self‐disclosure. Data from 137 counselor supervisors demonstrated a significant positive relationship between attractive, interpersonally sensitive, and task‐oriented supervisory styles and the (a) goals, tasks, and bond components of the supervisory working alliance and (b) frequency of supervisor self‐disclosure. Limitations and implications for counselor supervision theory, research, and practice are addressed.  相似文献

This study examined relations between behavioral inhibition (BI) assessed in toddlerhood (n = 268) and attention biases (AB) to threat and positive faces and maternal‐reported anxiety assessed when children were 5‐ and 7‐year‐old. Results revealed that BI predicted anxiety at age 7 in children with AB toward threat, away from positive, or with no bias, at age 7; BI did not predict anxiety for children displaying AB away from threat or toward positive. Five‐year AB did not moderate the link between BI and 7‐year anxiety. No direct association between AB and BI or anxiety was detected; moreover, children did not show stable AB across development. These findings extend our understanding of the developmental links among BI, AB, and anxiety.  相似文献

Findings presented here relate to the evaluation of a one-year father-inclusion project, which took place in an area of multiple deprivation in the North of England. The project's goal was to engage fathers and male carers in their children's transition from an early years setting to a reception class and to maintain that involvement in the mainstream school setting. The project was successful in engaging men, recording 76 male attendances, 19 of which were recorded at school-based activities after the transition. Key benefits identified by fathers engaged in the project were closer relationships with their children and greater involvement in their play and learning. Children were very positive about their fathers' involvement and school staff identified a better rapport with fathers following the project.  相似文献

This paper explores the central place of stories and narratives in action research practices and accounts to argue that it is hard to imagine how we might do or write about action research in a non‐storied way. The paper argues that good stories help us to think well and more wisely about ourselves and our practice. An historical example is chosen to illustrate the compelling potential of stories about real people and real lives, followed by a teasing out of six methodological issues that arise.  相似文献

We describe the efforts of a curriculum development team to create computerized virtual creatures for biology education. The original purpose was to create a virtual frog that biology students could dissect on computer. As the project developed, the vision changed radically. Instead of a virtual creature, the team created a virtual world, Frog Island, that contained a wealth of resources in various media for learning about the biology of frogs. The impetus for the shift from Virtual Frog to Frog Island came from a series of design studies in which the team discovered that the original vision did not match the needs of students and teachers. On the basis of this experience, we make a case for the value of early design studies in the development of educational innovations.  相似文献

Abstract

Following fixed-duration exercise of submaximal intensity, caffeine ingestion is associated with an attenuation of the exercise-induced decline in N-formyl-methionyl-phenyl-alanine (f-MLP) stimulated neutrophil oxidative burst. However, the response following high-intensity exhaustive exercise is unknown. Nine endurance-trained male cyclists ingested 6 mg caffeine or placebo per kilogram of body mass 60 min before cycling for 90 min at 70% of maximal oxygen consumption ([Vdot]O2max) and then performing a time-trial requiring an energy expenditure equivalent to 30 min cycling at 70% maximum power output. Time-trial performance was 4% faster in the caffeine than in the placebo trial (P = 0.043). Caffeine was associated with an increased plasma adrenaline concentration after 90 min of exercise (P = 0.046) and immediately after the time-trial (P = 0.02). Caffeine was also associated with an increased serum caffeine concentration (P < 0.01) after 90 min of exercise and immediately after the time-trial, as well as 1 h after the time-trial. However, the f-MLP-stimulated neutrophil oxidative burst response fell after exercise in both trials (P = 0.002). There was no effect of caffeine on circulating leukocyte or neutrophil counts, but the lymphocyte count was significantly lower on caffeine (20%) after the time-trial (P = 0.003). Our results suggest that high-intensity exhaustive exercise negates the attenuation of the exercise-induced decrease in neutrophil oxidative burst responses previously observed when caffeine is ingested before exercise of fixed duration and intensity. This may be associated with the greater increase in adrenaline concentration observed in the present study.  相似文献
