Voice is critical to youth; yet discerning and claiming a public religious voice is complicated, especially as youth encounter values that include or exclude them based on personality, ethnicity, religion, gender identification, ability, social class, or sexual orientation. Drawing from interviews, we analyze influences on youth to discover and speak their religious voices in public spaces, and to claim religious motivations for their public personas and actions. The study uncovers complex relationships among young people's religious awareness, social contexts, inner dynamics, and public religious expressions. These relationships suggest directions for religious education in faith communities, schools, and other public spaces.  相似文献

Discussion has long held an honored place in the pantheon of lionized adult education practices. One of the most frequently venerated aspects of discussion is opening up conversation to include the widest possible diversity of perspectives and intellectual traditions. This democratic attempt to be open and inclusive is held to represent what is best about adult education—its humanistic concern to have all voices heard, all experiences analyzed, and all viewpoints honored. Herbert Marcuse's concept of repressive tolerance stands directly against these sentiments. Marcuse argues that an alternative idea, concept or text can be inserted into a discussion of familiar, mainstream materials in such a way that serves only to underscore the normality of the center while positioning the alternatives as exotic others. This paper explores how this process occurs and suggests how it might be countered.  相似文献

The purpose of this research was to examine the consistency between students’ practical and formal understandings of scientific epistemologies (also known as nature of science (NOS) understandings) in the context of a research apprenticeship program. Six high school student participants of a residential summer research apprenticeship program at a major university in the southeastern USA were interviewed twice during their experience to elicit their perspectives regarding their practical epistemologies. A phenomenological approach was used to analyze these interviews. The students held practical epistemological understandings of scientific knowledge that were described as being developmental, valuable, formulaic, and authoritative. A survey administered at the end of the program was used to reveal students’ formal epistemologies of science. These practical and formal epistemologies were described in terms of Sandoval’s (Science Education 89:634–656, 2005) epistemological themes and then compared for all participants. Findings revealed that, for most students, at least some level of consistency was present between their formal and practical epistemological understandings of each theme. In fact, for only one student with one theme, no consistency was evident. These results hold implications for the teaching, learning, and assessment of NOS understandings in these contexts as well as for the design of apprenticeship learning experiences in science.  相似文献

Skin conductance level reactivity (SCLR) was examined as a moderator of the association between harsh parenting and child externalizing behavior. Participants were 251 boys and girls (8–9 years). Mothers and fathers provided reports of harsh parenting and their children's externalizing behavior; children also provided reports of harsh parenting. SCLR was assessed in response to a socioemotional stress task and a problem-solving challenge task. Regression analyses revealed that the association between harsh parenting and externalizing behavior was stronger among children with lower SCLR, as compared to children with higher SCLR. SCLR may be a more robust moderator among boys compared to girls. Results are discussed with regard to theories on antisocial behavior and multiple-domain models of child development.  相似文献

This study examined the predictive ability of the medicine ball chest throw and vertical jump for muscular strength and power in adolescents. One hundred and ninety adolescents participated in this study. Participants performed trials of the medicine ball chest throw and vertical jump, with vertical jump peak power calculated via an estimation equation. One-repetition maximum and peak power for the chest press and leg press were assessed using pneumatic exercise machines. The medicine ball chest throw strongly correlated with chest press one-repetition maximum and peak power, while the vertical jump peak power strongly correlated with leg press one-repetition maximum and peak power. The predictive ability of medicine ball chest throw was better than vertical jump peak power for muscular strength and power when controlling for sex, age, height, weight, and maturation, and was not affected by involvement in sports. Results show good predictive ability of the medicine ball chest throw for muscular strength and power in adolescents, while predictable ability of vertical jump peak power is weakened when other factors are taken into account.  相似文献

Background: In many countries around the world, physical education (PE) has been identified as a marginalized subject. PE teachers have been found to feel negative consequences associated with marginality, such as stress, burnout, and early career attrition. Recent evidence also indicates that physical educators can develop a sense of perceived mattering both in relation the subject of PE and their role as that teacher of that subject. Less is known, however, about the relationship between perceived mattering and marginalization, and how teachers navigate social messages associated with each that they receive while teaching. Role socialization theory has emerged as an approach to studying teachers’ experiences in school environments, and can be used to understand their experiences with marginality and mattering.

Aims: The purpose of this study was to understand how the social environment of schools influences PE teachers’ perceptions of marginalization and perceived mattering, and how these two constructs interact.

Method: The investigation was conceptualized as an interview study, and framed using a social constructivist epistemology. Participants included 30 in-service PE teachers (16 males, 14 females) from the Midwest region of the US. Data were collected using in-depth qualitative interviews, and analyzed through a collaborative approach to data analysis that drew upon both inductive and deductive forms of analysis.

Results: Participants identified experiences with both perceived mattering and marginalization in their work, and noted that sometimes these messages were contradictory. Some participants felt the effects of marginalization as their discipline was viewed as a dispensable commodity that is only meaningful for the service it provides to other teachers (e.g. gives elementary classroom teachers a break for planning). Some of the teachers internalized their marginal status and began to see their primary function as supporting the work of teachers in other subjects. Nevertheless, the participants derived a sense of mattering by building relationships with colleagues, administrators, and students, and by advocating for the discipline. Teachers also felt validated when colleagues acknowledge their attempts to implement effective practices, but struggled when working with colleagues who are resistant to change.

Conclusions: PE teachers experience both marginalization and perceived mattering, which are shaped largely by social interactions within the school environment. This study specifically lends to the view of marginalization and perceived mattering as two constructs at opposite ends of a continuum, rather than a binary conceptualization. This suggests that it could be the summation of marginalizing experiences and those that promote mattering that lead physical educators to develop overall impressions of their role in schools. Furthermore, this study adds to the literature indicating that physical educators may eventually internalize feelings of marginalization when consistently told that they do not matter. This has implications related to the washout effect whereby teachers who no longer feel as if they are making meaningful contributions to children’s education may compromise their teaching practice.  相似文献

This study tested the hypothesis that ischemic preconditioning (IPC) would increase critical power (CP) during a 3 minute all-out cycling test. Twelve males completed two 3 minute all-out cycling tests, in a crossover design, separated by 7 days. These tests were preceded by IPC (4 x 5 minute intervals at 220 mmHg bilateral leg occlusion) or SHAM treatment (4 x 5 minute intervals at 20 mmHg bilateral leg occlusion). CP was calculated as the mean power output during the final 30 s of the 3 minute test with W′ taken as the total work done above CP. Muscle oxygenation was measured throughout the exercise period. There was a 15.3 ± 0.3% decrease in muscle oxygenation (TSI; [Tissue saturation index]) during the IPC stimulus, relative to SHAM. CP was significantly increased (241 ± 65 W vs. 234 ± 67 W), whereas W′ (18.4 ± 3.8 vs 17.9 ± 3.7 kJ) and total work done (TWD) were not different (61.1 ± 12.7 vs 60.8 ± 12.7 kJ), between the IPC and SHAM trials. IPC enhanced CP during a 3 minute all-out cycling test without impacting W′ or TWD. The improved CP after IPC might contribute towards the effect of IPC on endurance performance.  相似文献
