In the golf instructional literature, the putting stroke is typically given higher priority than green reading and aiming. The main purpose of this study was to assess the importance of the putting stroke for direction consistency in golf putting. Kinematic stroke parameters were recorded from 71 elite golf players (mean handicap = 1.8, s = 4.2) on 1301 putts from about 4 m. Of the different factors deciding stroke direction consistency, face angle was found to be the most important (80%), followed by putter path (17%) and impact point (3%). This suggests that improvements in consistency of putter path and impact point will have very little effect on overall putting direction consistency and should not be prioritized in the training of elite players. In addition, mean stroke direction variability for an elite player (European Tour) was found to be 0.39 degrees, which is good enough to hole about 95% of all 4-m putts. In practice, however, top professionals in tournaments only hole about 17% of 4-m putts. We conclude that the putting stroke of elite golfers has a relatively minor influence on direction consistency. 相似文献

This article examines the current interest of educators in flipped learning. Although this concept has developed in the online and distance education literature over two decades, numerous current writers are attributing it to an idea formed in 2007 by two K–12 teachers in Colorado, USA. The mechanisms that generate such myths are examined, with emphasis on the confusions, defensive strategies, and blogfuscations that cause them in web sites and blogs. In its treatment of the flipped learning topic, Wikipedia.org, often regarded as lacking in accuracy and credibility, has demonstrated that a solid reviewing process can reduce the effects of hype and ensure that an accurate record is maintained. It is recommended that academic journals should enlist the help of their reviewing panels in monitoring hype as it arises and correcting accounts of it on, for example, Wikipedia as a vital quality control measure. 相似文献
