Since the survey of health sciences libraries by the American Medical Association in 1969, a number of other hospital library surveys have been conducted. Twelve hospital/health sciences library surveys published since the passage of the Medical Library Assistance Act are reviewed. The use of data from these surveys for management and planning is discussed and directions for future library survey development are suggested. 相似文献

This project is addressed to the effectiveness of video mediated instruction on the learning of the tennis service by novices. The research was carried out in an indoor tennis hall under normal training conditions. Three experimental groups were used: a video-model (VMT), a video-feedback (VFT) and a group with a combination of video modelling and video feedback (VMFT). Two control groups - based on different training periods-were also used: a traditional training group (TT1) which practised for a period of 45 min per training session and a second traditional training group (TT2) which practised for a period of only 30 min per training session. All subjects took part in five successive training sessions. No clear advantages of using video mediated instruction methods in teaching novices the tennis service could be demonstrated. Five sessions of 30 min practical training were shown to be as effective as five sessions of 45 min practical training in producing improvements in both form and achievement scores of novice tennis players. While, in the early stages, form and achievement scores were not shown to be significantly related, after five sessions a significant correlation (P less than 0.05) was shown. 相似文献
