Peer and near-peer teaching programs are common in medical undergraduate courses. However, there are no studies that have investigated the effectiveness of a near-peer teaching program on the academic performance of undergraduate students pursuing sport and exercise science coursework. This study was conducted to analyze the effectiveness of such a program for students who participated in a course on the functional anatomy of the locomotor apparatus. A total of 39 student participants were divided into two groups: students in one group voluntarily attended at least one session of a near-peer teaching program, and students in the other group attended no sessions. The final grade (range 0–100%) was recorded and used as an indicator of academic performance. The final grade of students who attended the near-peer teaching program (69.5 ± 16.0%) was 38.7% higher (P = 0.002, d = 1.06) than those who did not (50.1 ± 20.4%). When the academic performance of the same students was evaluated in another course (exercise physiology) that did not offer a near-peer teaching program, there were no significant differences between the groups (students who attended or did not attend the near-peer teaching program). A significant positive association was found between near-peer teaching program frequency and the number of students approved and not approved in the course (P = 0.041). A significant difference (P = 0.001) was found in the attendance at regular classes between the group who participated in the near-peer teaching program (median: 62 hours; IQR [interquartile ranges]: 4.0 hours) and those who did not (median: 58 hours; IQR: 4.0 hours). Gender was not a moderating factor on academic performance or near-peer teaching program attendance. These results highlight the effectiveness of a near-peer teaching program on the academic performance of students from a sport and exercise science degree program while enrolled in an anatomy course.

建立市场辅导机制下的"文化保护主义"体系——欧盟影视公共资助模式的思考     

罗青  Andre Lange 《现代传播》2007,(2):108-112

公共资助体系是欧洲国家对以影视为主导的文化创意产业的一系列重要的公共政策,起源于20世纪30年代。世界大战末期的欧洲成为美国电影及美国价值观主导的市场,如何保持欧洲产业的文化多样性和全球竞争力引起了欧洲业界的普遍危机认同。通过市场和文化的双轨措施实施的公共资助体系,开发出产业之区域整合与互惠模式,创造出一个全新的全球市场竞争力量,保持了欧洲各文化对美国文化强权的抗衡能力的政策模式和产业辅助体系。基于市场竞争和文化多样双重原则下建立起来的视听产业公共资助体系,以“经济和文化”的两手原则为指导,目的是为影视产业的市场化和文化价值服务,其建构的体系原则、资金来源、运营方式均值得尚处于产业化转型,尤其是文化体制改革进程中的中国影视业界借鉴。  相似文献   

The influence of ventilatory control on heart rate variability in children     

Williams CA  Lopes P 《Journal of sports sciences》2002,20(5):407-415

The aim of this study was to determine the influence of breathing frequency and tidal volume on resting heart rate variability in children aged 9 years (n = 29) and 16 years (n = 19). Heart rate variability was measured in four conditions: (1) without the control of ventilation followed at random by (2) a fixed breathing frequency of 12 breaths x min(-1), (3) a breathing frequency of 12 breaths x min(-1) but with a fixed tidal volume of 30% vital capacity and (4) a fixed breathing frequency of 6 breaths x min(-1) and a tidal volume of 30% vital capacity. A total of 128 RR intervals (the time between two spikes in the heart rate) were detected and absolute high- and low-frequency spectral components were calculated using autoregressive modelling. The younger children were unable to control ventilation to achieve conditions 3 and 4; therefore, a 2 x 2 (group x condition) analysis of variance was used to analyse conditions 1 and 2. There were significant interactions between group and heart rate variability conditions for the low-frequency component and the ratio of low to high frequencies (P < 0.001). The main effect for condition showed that at 12 breaths x min(-1) with no fixed tidal volume there was a significantly higher standard deviation of the RR interval, total power and high-frequency (P< 0.01) and low-frequency spectral components (P < 0.05) than in the condition with no ventilatory control. Across the four breathing conditions for the older participants, the high-frequency spectral component was significantly higher in the condition at 6 breaths x min(-1) with a fixed tidal volume than in that with no ventilatory control (P < 0.005); the ratio of high to low frequencies was significantly lower for the spontaneous condition than those performed at 12 breaths x min(-1) (P < 0.001). The results provide evidence of the need for ventilatory control when assessing short-term resting heart rate variability in children.  相似文献   

Correlations between serum and salivary hormonal concentrations in response to resistance exercise

The aim of present study was to examine the relationships between serum and salivary values of free testosterone, dehydroepiandrosterone, and cortisol before and after a session of resistance exercise. Twenty-eight healthy men (mean age 40 years, s = 4) participated in the present study. Serum and salivary samples were collected at rest and after a multiple-sets resistance exercise protocol, of approximately 25 minutes duration. Concentrations of free testosterone, dehydroepiandrosterone, and cortisol were measured using radioimmunoassay kits. No significant correlation was observed between serum free testosterone and salivary testosterone (r = 0.22 to 0.26, P > 0.05). Serum cortisol was significantly correlated with salivary cortisol before (r = 0.52, P = 0.005) and after (r = 0.62, P = 0.001) the exercise protocol. Serum and salivary concentrations of dehydroepiandrosterone were significantly correlated before (r = 0.68, P < 0.001) and after (r = 0.7, P < 0.001) exercise. The results of the present study suggest that even under exercise conditions, the salivary values of cortisol and dehydroepiandrosterone can reflect the behaviour of these hormones in blood. However, further studies are necessary to verify if salivary testosterone reflects the behaviour of serum free testosterone during resistance exercise.  相似文献   

Brazilian soccer: symbolic dimensions of its practice     

Luiz Henrique de Toledo 《Soccer & Society》2014,15(1):48-64

This essay explores the symbolic dimensions of soccer in Brazilian society from the perspective of sports anthropology. It discusses how the founding of the game was handled, in terms of stylization and standardization of rules. This, as the essay argues, would effect amplified representations in emotional regimes and adhesion to the game, thus making it a singular sports modality for understanding societies such as Brazil.  相似文献   

‘Learning Experience’ Provided by Science Teaching Practice in a Classroom and the Development of Students’ Competences     

J. Bernardino Lopes  Julia Branco  Maria Pilar Jimenez-Aleixandre 《Research in Science Education》2011,41(5):787-809

According to the literature, there is a very important corpus of knowledge that allows for the investigation of some dimensions of ‘learning experience’ provided to students, in relation to epistemic, pedagogical and meta-cognitive practices. However, in the literature, there is little investigation into the invariance (or not) of the characteristics of students’ learning experience while being taught a scientific subject by the same teacher. This paper suggests that the relationship between the learning experience provided and the competences developed is not properly highlighted. This paper analyses the learning experience provided to students in epistemic, pedagogical and meta-cognitive terms. The students were taught the proprieties and applications of light by one teacher, in three classes, over 7 weeks. We analysed the data in each referred learning experience, using a pre-defined category system. The students’ competences were evaluated by a competence test. The epistemic demand of each item and the students’ performances were also analysed. Our findings point to the non invariance of learning experiences provided to students and the influence of some dimensions of learning experiences provided in the development of certain competences. These findings and their implications are contextualized and discussed.  相似文献   

Using autobiographical queer life narratives of teachers to connect personal,political and pedagogical spaces     

Andre P. Grace  Fiona J. Benson 《International Journal of Inclusive Education》2013,17(2):89-109

Autobiographical queer life narratives are communicative spaces where queer teachers take up personal issues of being, becoming, and belonging in contextual and relational analyses of their situated experiences. In this work w/e consider the challenges and risks involved in this research, which, when shared and probed in classroom spaces, is a dangerous exposition of the queer self. With these challenges and risks in mind, w/e examine how our narratives provide fugitive knowledge to inform a pedagogy of ‘resist-stance’ that recognizes, respects, and engages queer identity, difference, history and culture. W/e provide examples of this pedagogy, discussing teaching strategies currently being used to connect the personal, the political and the pedagogical in classroom spaces. W/e also speak of the difficulties of living out this pedagogy as transformative teaching to transgress queer erasure in hetero-normative educational practice.  相似文献   

Analysing the professional development of teaching and learning from a political ethics of care perspective     

Vivienne Grace Bozalek  Wendy McMillan  Delia E. Marshall  Melvyn November  Andre Daniels  Toni Sylvester 《Teaching in Higher Education》2013,18(5):447-458

This paper uses Tronto's political ethics of care as a normative framework to evaluate a model of teaching and learning professional development. This framework identifies five integrated moral elements of care – attentiveness, responsibility, competence, responsiveness and trust. This paper explicates on each of these elements to evaluate the piloting and implementation of a teaching and learning professional development model at a South African higher education institution. The political ethics of care was found to be a useful normative framework for a group of higher educators to reflect on the process of engaging in teaching and learning professional development in that it revealed the importance of differential power relations, the importance of working collaboratively and being attentive to the needs of both caregivers and care receivers.  相似文献   

A One-year Case Study: Understanding the Rich Potential of Project-based Learning in a Virtual Reality Class for High School Students     

Teresa M. Morales  EunJin Bang  Thomas Andre 《Journal of Science Education and Technology》2013,22(5):791-806

This paper presents a qualitative case analysis of a new and unique, high school, student-directed, project-based learning (PBL), virtual reality (VR) class. In order to create projects, students learned, on an independent basis, how to program an industrial-level VR machine. A constraint was that students were required to produce at least one educational application of VR. This study incorporated in-depth classroom observations, interviews with students, analyses of student projects, and surveys of parents and teachers to examine the social and learning processes in the class, and the nature of content learning represented in student projects. The results demonstrated that PBL can be effective even with minimal teacher guidance. The findings substantiate an educational approach rich with promise, for at least some students, that deserves considerable additional study to maximize its powerful potentials for independent and peer-mentored learning.  相似文献
