论运动训练学的逻辑起点与理论体系

随着相关学科的不断发展,运动训练学的内容日趋完善并在实践中起到越来越重要的作用。通过文献收集与分析、逻辑推理等方法,提出运动训练学的逻辑起点是身体训练,而当前的理论体系尚不完善,仍需不断改进。     

Variable training: effects on velocity and accuracy in the tennis serve

Abstract

Variable practice has been shown to be an effective strategy to improve open motor skills. However, the usefulness of this procedure in closed motor skills remains controversial. The following study has the objective of analysing the effects of variability practice in the improvement of a closed skill. The skill studied has been the tennis serve. Thirty young tennis players (13 ± 1.52 years), divided in two groups, took part in this study. One group practiced in variable conditions and the other group in consistency conditions. Both groups performed 12 training sessions (60 serves/session). The variable practice group improved their accuracy significantly compared with the consistency group (F_3.25 = 3.078; P = 0.035). The velocity of serve increased after training in both groups (F_3.25 = 15.890; P = 0.001). The practice in variable conditions seems to be effective in improving the performance of the tennis serve.     

Theoretical Analysis of Aggressive Golf Putts

Abstract

The present study examined the relationship between students' perceptions of the motivational climate and beliefs about the causes of success, preference for challenging tasks, and satisfaction in physical education. Responses of 50 female and 46 male students (M age = 12.08 years; SD = .72) showed that perceptions of a mastery-oriented motivational climate were related to the belief that motivation or effort caused success and satisfaction. In contrast, perceptions of a performance climate were related to the belief that deception caused success and related negatively to the students' preference for challenging tasks. Results of hierarchical regression analyses revealed that perceptions of the motivational climate explained a significant amount of unique variance in the students' responses after controlling for dispositional goal orientations. The results suggest that the teacher can influence the salience of a mastery-oriented climate and, in so doing, optimize a child's motivation in physical education.     

论邓小平理论体系的逻辑结构

文章认为，只有运用实事求是和历史与逻辑相统一的原则和方法研究邓小平理论体系，才能建立起一个由概念的逻辑推演所构成的前后内容一贯的理论体系。邓小平理论体系的逻辑起点是邓小平的社会主义概念。由邓小平的社会主义概念可以逻辑地推导出他的整个建设有中国特色社会主义理论体系的基本内容．构造出一个符合邓小平理论实际的逻辑体系结构。

先秦逻辑意识因何没有发展成中国逻辑学

美妙的先秦逻辑意识昙花一现,没有结出任何果实。本文在逻辑大师金岳霖先生研究的基础上,分析了造成这一现象的部分原因,如：逻辑意识与思维内容不分,不利于形成专门的学问;先秦逻辑意识的“诡辩”恶名使逻辑意识后继无人;涉及先秦逻辑意识的重要著作语言晦涩难懂,使后人难以继承并发扬光大。
