ABSTRACTThe purpose of the study was to assess the validity and inter-bike reliability of 10 Wattbike cycle ergometers, and to assess the test–retest reliability of one Wattbike. Power outputs from 100 to 1000 W were applied using a motorised calibration rig (LODE) at cadences of 70, 90, 110 and 130 rev · min?1, which created nineteen different intensities for comparison. Significant relationships (P < 0.01, r2 = 0.99) were found between each of the Wattbikes and the LODE. Each Wattbike was found to be valid and reliable and had good inter-bike agreement. Within-bike mean differences ranged from 0.0 W to 8.1 W at 300 W and 3.3 W to 19.3 W at 600 W. When taking into account the manufacturers stated measurement error for the LODE (2%), the mean differences were less than 2%. Comparisons between Wattbikes at each of the nineteen intensities gave differences from 0.6 to 25.5 W at intensities of 152 W and 983 W, respectively. There was no significant difference (P > 0.05) between the measures of power recorded in the test–retest condition. The data suggest that the Wattbike is an accurate and reliable tool for training and performance assessments, with data between Wattbikes being able to be used interchangeably. 相似文献

Background: In recent years increasing attention has been given to models-based approaches to physical education as a way of promoting standards and particular types of learning through better alignment of teacher planning and delivery with pupil learning and achievement. However, little attention has been given to the specific contribution a pedagogical model for outdoor adventure education (OAE) has to make to pupils learning.
Purpose: This paper is presented in two parts. Part one is an advocacy paper and draws upon the broader discourse around models-based practice to make a case for the development of a pedagogical model for OAE. Drawing upon guidelines for models-based approaches to physical education, this paper considers the theoretical foundation, rationale, review of research findings and major theme that inform the development of a model of OAE.
Conclusions: The selected review of the research suggests that the major impact of OAE is upon the affective domain, particularly in relation to pupils developing a positive self-concept. Learning is also evident in the cognitive and physical domains, but this is secondary to learning in the affective domain. Drawing upon the analysis of the research literature, the major theme for the model is identified as ‘personal growth through adventure’ and ‘OAE’ is suggested as the name of the model. Part two of this paper builds upon these foundations to outline what a pedagogical model for OAE might look like in a secondary school in the UK. 相似文献

This paper analyses the results of a research project on the experiences and learning needs of students with dependent children in a 1960s university. The findings are based on semi‐structured interviews with university services and academic staff, as well as a questionnaire survey among students with dependent children and follow‐up in‐depth interviews with a sample of 18 of these students. The paper shows that, for those surveyed, future employment opportunities and being a role model for their children were the main motivations for entering higher education and that their choice of university was highly spatially restricted by their caring responsibilities. It also discusses the main issues students faced once at university, including time and timing, finance, childcare, confidence, sense of belonging and skills. The paper highlights how gender and other biographical characteristics influence parents' experiences and includes suggestions for lessening the barriers they face while at university. 相似文献

Maternal mind-mindedness and attachment security as predictors of theory of mind understanding 总被引：1，自引：0，他引：1

This study investigated relations between social interaction during infancy and children's subsequent theory of mind (ToM). Infant-mother pairs (N = 57) were observed in a free-play context at 6 months. Interactions were coded for (a) mothers' use of mental state language that commented appropriately on the infants' mental states, and (b) mothers' use of mental state language that did not appropriately reflect their infants' minds. A third variable was (c) security of attachment, which was assessed using the Strange Situation procedure at 12 months. Performance on a battery of ToM tasks at 45 and 48 months was positively correlated with (a), but was not related to (b) or (c). A regression analysis showed that mothers' use of appropriate mental state comments independently predicted overall ToM performance, accounting for 11% of the variance. Children's verbal ability was the only other independent predictor of ToM performance, accounting for 16% of the variance. These findings represent the earliest known social predictor of individual differences in ToM. 相似文献

Pathways to understanding mind: construct validity and predictive validity of maternal mind-mindedness 总被引：6，自引：0，他引：6

The construct validity of maternal mind-mindedness (MM) was investigated in the context of its relations with children's later understanding of mind. MM measures were obtained from infant-mother (N = 52) interactions at 6 months, and from maternal interviews at 48 months. Children's understanding of mind was assessed using theory of mind (ToM) tasks at 45 and 48 months, and a stream of consciousness (SoC) task at 55 months. One of the early MM measures--mothers' appropriate mind-related comments--was a positive independent predictor of: (a) MM at 48 months, and (b) ToM and SoC performance at 45 to 55 months. Path analyses suggested direct links between mothers' use of appropriate mind-related comments and children's later understanding of mind. 相似文献

Family learning has been an important mode of education deployed by governments in the United Kingdom over the past 20 years, and is positioned at the nexus of various social policy areas whose focus stretch beyond education. Drawing on qualitative research exploring mothers’ participation in seven different family learning programmes across West London, this paper looks at how this type of education is mobilised; that is, how mothers are ‘encouraged’ to participate and benefit from this type of programme. Framed by a neo-liberal policy climate and Foucauldian writings on governmentality and surveillance, we explore how participating mothers are carefully ‘targeted’ for this type of learning through their children and through school/ nursery spaces, and how programmes themselves then operate as a supportive social space aimed at facilitating social networks, friendship and personal development linked to positions of gender, ethnicity, class and migrant status. It is the socio-spatial workings of ‘supportive’ power and power relations that enable family learning to be mobilised that ensures its popularity as a social policy initiative. 相似文献

The International Charter for Physical Education, Physical Activity, and Sport clearly states that vested agencies must participate in creating a strategic vision and identify policy options and priorities that enable the fundamental right for all people to participate in meaningful physical activity across their life course. Physical literacy is a rapidly evolving concept being used in policy making, but it has been limited by pre-existing and sometimes biased interpretations of the construct. The aim of this article is to present a new model of physical literacy policy considerations for key decision makers in the fields of public health, recreation, sport, and education. Internationally debated definitions of physical literacy and the wider construct of literacy were reviewed in order to establish common pillars of physical literacy in an applicable policy model. This model strives to be consistent with international understandings of what “physical literacy” is, and how it can be used to achieve established and developing public health, recreation, sport, and educative goals. 相似文献
