This paper aims to shift the debate on the Learning Society away from the normative focus which has predominated hitherto. Rather than beginning with questions about what a Learning Society ought to constitute, we seek to engage with the patterns of participation in learning through the life‐course and their determinants. Our discussion begins with an examination of the way in which the official discourse of the Learning Society is dominated by human capital theory. The critical evaluation of the latter is thus a serious undertaking. Human capital theory involves an unwarranted abstraction of economic behaviour from social relations more widely; participation in lifetime learning cannot be understood in terms of the narrow calculation of utility maximization. This critique provides the basis for the development of a more satisfactory theoretical account, in which learning behaviour is conceived as the product of individual calculation and active choice, but within parameters set by both access to learning opportunities and collective norms. These parameters, by their very nature, vary systematically over space and time: accordingly, place and history must play a central role in any adequate theorization. We conclude that this kind of theoretical approach has important implications not only for empirical research, but also for strategies aimed at creating a Learning Society. 相似文献

Chronic elbow injuries from tumbling in female gymnastics present a serious problem for performers. This research examined how the biomechanical characteristics of impact loading and elbow kinematics and kinetics change as a function of technique selection. Seven international-level female gymnasts performed 10 trials of the round-off from a hurdle step to flic-flac with ‘parallel’ and ‘T-shape’ hand positions. Synchronized kinematic (3D-automated motion analysis system; 247 Hz) and kinetic (two force plates; 1,235 Hz) data were collected for each trial. Wilcoxon non-parametric test and effect-size statistics determined differences between the hand positions examined in this study. Significant differences (p < 0.05) and large effect sizes (ES>0.8) were observed for peak vertical ground reaction force (GRF), anterior–posterior GRF, resultant GRF, loading rates of these forces and elbow joint angles, and internal moments of force in sagittal, transverse, and frontal planes. In conclusion, the T-shape hand position reduces vertical, anterior–posterior, and resultant contact forces and has a decreased loading rate indicating a safer technique for the round-off. Significant differences observed in joint elbow moments highlighted that the T-shape position may prevent overloading of the joint complex and consequently reduce the potential for elbow injury. 相似文献

Recent research focusing on professional experience has shifted towards understanding preservice teachers' learning. The aim of this study was to gain insight into the learning of preservice Physical and Health Education teachers throughout three progressively designed professional experiences. Ten volunteering first-year preservice teachers, who were enrolled in a four year degree, were recruited. A qualitative practitioner inquiry approach was employed, with participants interviewed twice to provide insights into their learning and theorising of practice. Key themes emerged around the relationship between the unit content (theory) and professional experience (practice); notions of professionalism; engagement with the syllabus and lesson planning; communication; and understanding of students. Findings indicate the potential of microteaching placements as stepping-stones to larger, more intense professional experience placements. However, future research is needed to provide stronger evidence for these placements. 相似文献
