Research suggests that social support can be an important coping resource for athletes recovering from sport injury. Few studies have investigated this claim, however. To address this gap in the literature, 10 elite downhill skiers who had recovered from serious sport injuries were interviewed about the sources of stress associated with injury and the role of social support in recovery from sport injury. This paper presents the social supportfindings that emergedfrom this research'. Content analyses of the social support data revealed that the skiers needed various types of emotional, informational, and tangible support from the occurrence of injury through the return to full activity. Members of the treatment team, the ski team, and the skiers' home support net works provided social support throughout these phases. In general, the skiers were satisfied with the support received, indicating that it reduced distress and kept them motivated throughout recovery. The findings from this research have implications for the design of sport injury interventions. 相似文献

In order to determine the potential of alternative technologies in social studies education, we must understand the goals
of such education, the capabilities of the technologies, and teachers’ and students’ responses to new technologies. The author
suggests that the new technologies can contribute to the goals of learning about the past, learning about democratic life
and institutions, and making students knowledgeable as consumers and producers of information. One major obstacle is a lack
of time and money for teachers to experiment with the technologies.
Stephen T. Kerr is professor of education in the College of Education at the University of Washington. His research focuses
on the application of new technologies in schools and other educational environments, and particularly on the ways in which
technology affects the social structure (roles and expectations, instructional patterns, organization) of those institutions.
He has done work on human-computer interaction, as well as on how new communication technologies have changed the educational
system of the former USSR. 相似文献
