Previous research investigating the response of plasma ß‐endorphins (ß‐EP) to resistance exercise has resulted in equivocal findings. To further examine the effects of resistance exercise on ß‐endorphin immunoreactivity, six resistance‐trained athletes participated in a three‐set series of eight repetitions of isotonic exercise. All exercises were performed at 80% maximal effort. Blood was sampled from the group by venepuncture, both prior to and following the exercise bout, and ß‐endorphin concentration was determined by radioimmunoassay. The results indicated that mean ( ± S.E.) plasma levels of ß‐endorphins following exercise (18.04 ± 3.4 pg ß‐EP ml‐1) were not significantly changed from pre‐exercise (control) levels (19.59 ± 2.4 pg ß‐EP ml‐1), although there was considerable inter‐individual variability. Our results support previous research which has reported no significant changes in ß‐endorphin immunoreactivity following resistance exercise, as well as reported findings of considerable variability in the ß‐endorphin response to exercise. 相似文献

Partnerships and collaboration have become popular in higher education; and partnerships with community agencies, K-12 schools, and businesses are common. However, formal and sustained partnerships among institutions of higher education are not nearly as widespread. This article presents a model for collaboration in higher education focused on a partnership among teacher preparation programs at three institutions. The article provides an overview of theoretical underpinnings for collaboration, the process and practices used, and lessons learned by Valley Partnership, as well as the stages of partnership development, the governance model, and key elements related to sustaining the partnership. 相似文献

As our schools become increasingly diverse and the effects of immigration can be felt across the nation, some states have mandated that preservice teachers take endorsement courses that focus on teaching English Language Learners (ELLs) with the purpose of ensuring that teachers are able to meet ELLs' social and academic needs. A significant factor in improving instructional practices for ELLs is preservice teachers' confidence in their ability to teach ELLs successfully. What remains to be seen, however, is how best to organize and implement endorsement courses so that they have a positive effect on teachers' confidence to use their new knowledge to teach in effective ways. In this study, we discuss how endorsement curricula can build teachers' self-efficacy for teaching ELLs by not just covering the required content, but by being conscientious in how the curricula are organized and delivered. By providing teachers with the foundational knowledge through the use of meaningful and engaging pedagogical practices, preservice teachers' efficacy and beliefs about instructing ELLs will increase. This, in turn, will provide them with the confidence to teach those who may be very different culturally and linguistically from themselves. 相似文献

Discourse and the new didactics of scientific literacy 总被引:1,自引:1,他引:0
This study examines ways in which students’ experiences of a culturally‐sensitive curriculum may contribute to their developing sense of ethnic identity. It uses a narrative‐inquiry approach to explore students’ experiences of the interaction of culture and curriculum in a Canadian inner‐city, middle‐school context. It considers ways in which the curriculum may be interpreted as the intersection of the students’ home and school cultures. Teachers, administrators, and other members of the school community made efforts to be accepting of the diverse ethnic, linguistic, and religious backgrounds that students brought to the school. However, examination of students’ experiences of school curriculum events and activities revealed ways in which balancing affiliation to their home cultures while at the same time abiding by expectations of their teachers and peers in their school context could be difficult. The stories highlight ways in which curriculum activities and events may contribute to shaping the ethnic identity of students in ways not anticipated by teachers, administrators, and policy‐makers. 相似文献

The present study examined the linkages among perceptions of self-efficacy, curriculum, and field experience on students’ attitudes and interest in working with older adults. Graduate level social work students were surveyed regarding perceived self-efficacy to intervene with older adult clients, the amount of aging content in the master of social work (MSW) curriculum, and practicum experience with older clients. Regression analysis showed a relationship between attitudes toward older adults and perceptions of self-efficacy. Pearson correlations revealed that self-efficacy was significantly related to levels of gerontology content in curriculum, as well as practicum opportunities to work with older adults. While both gerontology curriculum and practice experience significantly predicted self-efficacy, multiple regression analysis revealed that practice experience had the stronger influence. 相似文献

Learning and effective teaching are both complicated acts. However, many administrators, teachers, parents, and policymakers
appear not to recognize those complexities and their significance for practice. Fueling this perception, recommendations from
isolated research findings often neglect the complexities in learning and teaching, and when implemented in classrooms often fall
well short of the advertised effect. Consequently, education research is generally ignored, and the resulting research-practice
gap raises concerns regarding the utility of university-based teacher education, and education research more generally. However,
the strength of education research resides in the synergy resulting from its integration into a unifying system that guides,
but does not determine, decision-making. Dewey (1929) argued for teacher decision-making guided by education research, but recently several writers have justly criticized education
researchers for not providing comprehensible assistance to educators and policymakers (Good, 2007; Shymansky, 2006; Windschitl, 2005). This paper proposes a decision-making framework for teaching to help beginning and experienced teachers make sense of education
research, come to understand crucial teacher decisions, and how those decisions interact to affect student learning. The proposed
decision-making framework for teaching has significant utility in the design of science methods courses, science teacher education
programs, effective student teacher supervision experiences, and professional development workshops. 相似文献

This study investigates word reading skill in Down Syndrome (DS). Two main questions are addressed: (1) Is reading an island of ability in DS? and (2) What are the cognitive correlates of word reading ability in DS? In particular, how do language versus visual-spatial skills relate to individual differences in reading ability in DS? Participants were 19 individuals with DS, ranging in age from 10 to 19 years, and 19 typically developing children (mean age = 4.9 years) matched with the DS individuals for mental age. Overall, reading ability in DS was very poor. There was no evidence that reading represents an “island of ability” in DS; instead, the average reading level of DS participants was even lower than would be predicted by their IQ. However, there were substantial individual differences in literacy among DS participants. DS word reading and spelling skill correlated strongly with the ability to read by phonological recoding. It also correlated with several language measures. As a matter of fact, the often reported language-mental age gap was found only among the poor readers with DS. 相似文献

This study demonstrates that NVivo, a popular research tool for content analysis, produces biased Cohen’s kappa as it calculates the reliability statistic at the character level, which is unsuitable for most content-analytic studies adopting a higher unit of analysis (e.g., sentence, paragraph). Based on empirical data and a statistical simulation, this study proposes a method of bias correction applicable to situations where two independent raters conduct binary coding. 相似文献

The researchers used a dialectical framework to examine interviews with wives whose elderly husbands experienced adult dementia from Alzheimer's disease and related disorders (ADRD), centering on how wives coped communicatively with their husbands' illness. These "married widows" experienced a primary contradiction between their husbands' physical presence and cognitive/emotional absence. Interwoven with the presence-absence contradiction were three additional contradictions: certainty-uncertainty, openness-closedness, and past-present. Results describe the ways these wives communicatively negotiated the web of contradictions as they interacted in the present with husbands they once knew. Applications for practitioners and caregivers working with ADRD patients and their wives, including formal and informal support, understanding, and managing contradictions, and ways to more effectively interpret ADRD patients' communication, are discussed. 相似文献
