The problem of reducing withdrawal and enhancing the lives of nursing home patients and other elderly members of society becomes more serious as the number of aged increases. Declines in the ability of elderly may be attributable, in certain cases, to disuse of intellectual capacities. Social reinforcement through reading activities has been proposed as a means of enhancing the performance of the aged and relieving the pain of social deprivation. In order to investigate this hypothesis, two reading groups were formed in a 100‐bed convalescent home; each group met for 6 weeks for 45 minutes. Short stories of high interest were read and discussed. Patients appeared to appreciate and enjoy the sessions. Problems of conducting similar programs were discussed and further research suggested. 相似文献

Although peer-based work is encouraged by theories in developmental psychology and although classroom interventions suggest
it is effective, there are grounds for recognising that young pupils find collaborative learning hard to sustain. Discontinuities
in collaborative skill during development have been suggested as one interpretation. Theory and research have neglected situational
continuities that the teacher may provide in management of formal and informal collaborations. This experimental study, with
the collaboration of the science faculty in one urban secondary college, investigated the effect of two role attribution strategies
on communication in peer groups of different gender composition in three parallel Year 8 science classes. The group were set
a problem that required them to design an experiment to compare the thermal insulating properties of two different materials.
This presents the data collected and key findings, and reviews the findings from previous parallel studies that have employed
the same research design in different school settings. The results confirm the effectiveness of social role attribution strategies
in teacher management of communication in peer-based work. 相似文献

Ankle sprains are the most common injury in sport. With stability being an important risk factor for ankle sprains, a jump-landing protocol that can elicit differences in time-to-stabilisation (TTS) is necessary. The objective of this study was to develop a jump-landing protocol that could identify differences in TTS among healthy, ‘coper’, and unstable ankles of high-level athletes. 61 Division I collegiate athletes (32 females, 29 males; age: 19.9 ± 1.2 years; height: 176.6 ± 9.5 cm; mass: 74.3 ± 10.8 kg) participated in a jump-landing protocol that utilised sporting movements with preparatory steps and a vertical propulsion of the body in two multi-directional jumps. Utilising the landing on a force plate, ground reaction forces were used to quantify TTS. TTS of the unstable group (1.58 ± 0.62s) was significantly longer than the healthy (1.19 ± 0.37s; p = 0.050) and ‘coper’ (1.13 ± 0.49s; p = 0.019) groups in the forward hops. In addition, TTS of the lateral hops in the unstable group (1.55 ± 0.63s) was also significantly longer than the healthy (1.14 ± 0.37s; p = 0.026) and ‘coper’ (1.15 ± 0.39s; p = 0.028) groups. This new jump-landing protocol was able to elicit differences in TTS in high-level athletes that were not found using previous protocols. This new jump-landing protocol could be an effective tool to identify injury risk for high-level athletes. 相似文献

This paper considers factors that influenced long-term engagement in an online community. It draws on a case study of a 6 year
online collaboration amongst a group of European teachers. The email interchange between these teachers was, with their agreement,
saved and used as research data; intensive group interviews were also conducted, involving all the participants in the online
group. Dynamic motivation models and Csikszentmihalyi’s concept of motivational flow were used to create a theoretical framework
to analyse the email interchanges and group interview data so as to build an understanding of the teachers’ commitment to
the online community. As a result of the analysis, the existing theoretical models were modified to produce a new combined
model. This incorporates ideas grounded in the participants’ reasons for their sustained engagement in the collaboration.
This combined model could provide a basis for planning future virtual interactions and for assessing their sustainability. 相似文献
