The aim of this study was to determine whether a constructivist approach, in particular a visit to a zoo, could be effective in consolidating mechanical concepts and applying those concepts to coaching and teaching. Ten students in their final year of their Bachelor of Physical Education at the University of Edinburgh participated in a visit to Edinburgh Zoo. During the visit students completed a worksheet of questions and engaged interactively in discussing how various animals are adapted mechanically to survive in their environments. Immediately after the visit they completed a questionnaire with four sections. The first section assessed whether they could apply the mechanical concepts discussed during the visit to human sports performance. The second canvassed their opinions on whether the visit was effective in reinforcing mechanical concepts, in developing 'lateral thinking' about mechanical concepts, and in improving their ability to apply mechanical concepts to coaching and teaching. The third canvassed their opinions on whether the visit would be effective for senior high school Physical Education and Sports Science students for developing mechanical concepts and applying them to coaching. The fourth section canvassed their opinions on when the visit should be conducted for Physical Education and Sports Science students in universities and in senior high schools. The results indicated that the visit was effective in reinforcing mechanical concepts and in applying them laterally to improve understanding of human sports performance. Participants believed that the visit would also be effective for senior high school students. All participants believed that the visit would be most beneficial after at least one course in biomechanics that covers the basic biomechanical principles. 相似文献

The purpose of this study was to compare timing and technique of males and females performing reverse twisting dives in elite international competition. Video data of the dives performed at the 1999 FINA World Diving Cup were captured and digitised to obtain times and postures of the divers at specific events including takeoff and entry. Estimates of flight height and mass-normalised work done on the springboard were obtained from flight times. The data indicated that many males are able to complete an additional twist rotation because they attain more height, and therefore more time in the air, than females. 相似文献

The notion of imagination is central to our contemporary western conception of and valuing of art. Yet the conception of imagination
upon which this valuing rests is based on certain assumptions about art-making and about persons. Imagination refers to the
creation of an idea or artifact from the mind of the creator. That a work of art arises from the imagination of an artist
is thus taken to mean that the work is a reflection of the person's individuality, an authentic product of the artist's inner
being. As such is will be marked by originality since each person is unique. There is, moreover, a belief that external constraints
on the imagination of the artist are inhibiting and that she should be free to express her visions or emotions without constraints.
Historically, however, the centrality of imagination viewed in this way has been the product of gradual development. This
paper examines one particularly important moment in this development, that is, the Renaissance in Italy. By examining the
changes in the nature, practice, and conception of art during this period, the paper probes the changing assumptions about
the connection between imagination and art. 相似文献

The present study examines in toddlers one of the most crucial components of empathy—attention to distress, and, in particular, attention to distress in a daycare setting where others' distress is a frequent occurrence. Characteristics of the child such as age, gender, and frequency of self-distress, and characteristics of the distress incident itself such as type of cry, intensity, cause of distress, and caregiver response were examined in relation to level of responsiveness of the group and level of attending in the individual child. 45 toddlers from 4 daycare centers served as subjects. An ANOVA using 345 distress incidents and level of group responsiveness as the dependent variable revealed that crying and screaming, greater intensity, caregiver responding in general, and “moral” (Turiel, 1983) causes of distress were related to higher levels of attending by the group. An interesting secondary finding was that only 11 of the 345 incidents of distress were responded to with prosocial behavior. Results are discussed in terms of the future of moral education at the preschool level. 相似文献

Supplemental Educational Services (SES), a component of the No Child Left Behind (NCLB) Act, provides free tutoring to economically disadvantaged children who are attending Title I schools in their 2nd or more years of school improvement. This research evaluated SES in Tennessee to determine the: (a) impacts on student achievement, and (b) perceptions of SES implementation and outcomes by teachers, district coordinators, principals/site coordinators, and parents. Using value-added methodology, statistical analyses of achievement data controlled for both student ability and teacher effects in 2 alternative models. Not surprisingly, parent reactions to SES were highly positive, whereas those by the 3 other stakeholder groups were more mixed. Achievement results from both analytical models yielded mostly small and nonsignificant provider effects. The implications of the findings for evaluating SES are discussed with regard to both research and policy issues. Recommendations are offered for broadening the evaluation of SES through smaller mixed-methods studies to examine implementation and educational outcomes in more highly controlled contexts. 相似文献
