There have been a number of earlier investigations, using differing methodologies, into the extent to which teachers in the secondary school interact with boys and girls and the results have suggested an imbalance in the teachers’ verbal behaviour towards the genders that is quite similar to the imbalance found in teachers’ behaviour in the primary school. The main aim of this study was to devise an investigation using the same methodology as that used in a recent primary school investigation in order to be able to make a fair comparison between the two levels. The results showed considerable differences in the teachers’ verbal behaviour towards the genders in the secondary school from that of teachers in the primary school. Where the primary school data showed teachers interacting more with the boys than the girls and the boys being less on‐task than the girls, the secondary school data showed no such differences. 相似文献

This paper reports on a writing program to support academic staff to publish in peer-refereed journals. Nine participants completed a 12-week program, which involved regular meetings, set writing tasks, and peer feedback on drafts. A pre- and post-survey and follow-up interviews were used to gather feedback. Participants especially valued the discipline of weekly sessions and peer feedback. They reported increased skills and confidence in their writing, greater knowledge of the publication process, and intention to continue writing. Although five papers were published, a 12-month follow-up revealed that original writing intentions were not sustained. Thus, while a structured writing program can be effective, the pressures academic staff experience trying to meet conflicting requirements of teaching, administration, and research, must also be addressed. 相似文献

AbstractThe aim of this study was to test the correlation between knee-to-hip flexion ratio during a single leg landing task and hip and knee strength, and ankle range of motion. Twenty-four male participants from a professional soccer team performed a continuous single leg jump-landing test during 10s, while lower limb kinematics data were collected using a motion analysis system. After biomechanical testing, maximal isometric hip (abduction, extension, external rotation), knee extension and flexion strength were measured. Maximum ankle dorsiflexion range of motion was assessed statically using the weight bearing lunge test. Pearson correlation coefficients were calculated to determine the associations between the predictor variables (knee and hip strength, and ankle ROM) and the main outcome measure (knee-to-hip flexion ratio). Correlation between knee-to-hip flexion ratio and hip abductors strength was significant (r = ?0.47; p = 0.019). No other significant correlations were observed among the variables (p > 0.05). These results demonstrated that a lower hip abductors strength in male soccer players was correlated with a high knee-to-hip flexion ratio during landing from a single leg jump, potentially increasing knee overload by decreasing energy absorption at the hip. The results provide a novel proposal for the functioning of hip muscles to control knee overload. 相似文献

This study aimed to validate the Sedentary Sphere posture classification method from wrist-worn accelerometers in children. Twenty-seven 9–10-year-old children wore ActiGraph GT9X (AG) and GENEActiv (GA) accelerometers on both wrists, and activPAL on the thigh while completing prescribed activities: five sedentary activities, standing with a phone, walking (criterion for all 7: observation) and 10-min free-living play (criterion: activPAL). In an independent sample, 21 children wore AG and GA accelerometers on the non-dominant wrist and activPAL for two days of free-living. Per cent accuracy, pairwise 95% equivalence tests (±10% equivalence zone) and intra-class correlation coefficients (ICC) analyses were completed. Accuracy was similar, for prescribed activities irrespective of brand (non-dominant wrist: 77–78%; dominant wrist: 79%). Posture estimates were equivalent between wrists within brand (±6%, ICC > 0.81, lower 95% CI ≥ 0.75), between brands worn on the same wrist (±5%, ICC ≥ 0.84, lower 95% CI ≥ 0.80) and between brands worn on opposing wrists (±6%, ICC ≥ 0.78, lower 95% CI ≥ 0.72). Agreement with activPAL during free-living was 77%, but sedentary time was underestimated by 7% (GA) and 10% (AG). The Sedentary Sphere can be used to classify posture from wrist-worn AG and GA accelerometers for group-level estimates in children, but future work is needed to improve the algorithm for better individual-level results. 相似文献
