The present study investigated the children’s capabilities of utilizing analytic strategies in Chinese character learning using an associative pseudocharacter learning paradigm. The participants were 54 Chinese primary school children (26?second graders and 28 fifth graders) who completed a pseudocharacter learning task that was followed by a generalization test. Repeated measures ANOVA results showed a significant main effect of block and grade in pseudocharacter learning. One-sample t-test results indicated that generalization performance was significantly better than chance level in both grade levels. Findings from this study suggested that Chinese primary school children were able to identify print–sound–meaning regularities that were not explicitly taught and apply those rules to learning new pseudocharacters. They contribute to a comprehensive understanding of the character learning processes in Chinese children when encountering new characters.  相似文献

The aim of this study was to identify those kinematic characteristics that are most closely related to an athlete's medical classification and measured distance of a put. Two S-VHS camcorders (60 fields per second) were used to record the performance of 17 males of different classes. Each participant performed six trials and the best trial for each was selected for analysis. Three-dimensional kinematics of the shot and upper body segments at the instant of release and during the forward thrust (delivery) were determined. The average speeds and angles of the shot at release for different classes (5.3-7.8 m x s(-1) and 21.2 to 34.4 degrees, respectively) were smaller than those exhibited by elite male able-bodied throwers. The height of the shot at release, the angular speed of the upper arm at release, the range of motion of the shoulder girdle during the delivery, and the average angular speeds of the trunk, shoulder girdle and upper arm during the delivery, were all significantly correlated with both the classification and measured distance (P < 0.05). The results indicate the importance of achieving a high average angular speed for each upper body segment during the delivery.  相似文献

Health benefits of Kung Fu: a systematic review   总被引:1,自引:1,他引:0  
The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of "hard" Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field.  相似文献

This article provides a brief overview of the framework of nonlinear pedagogy and evidence emanating from motor learning literature that underpins a nonlinear pedagogical approach. In addition, challenges for nonlinear pedagogy and a discussion on how nonlinear pedagogy support the work of physical education (PE) teachers will be shared. Evidence from the increasing volume of work on nonlinear learning from motor learning literature is used to suggest how acquisition of movement skills is supported by nonlinearity. The emergence of goal-directed behaviors is a consequence of the performer, environmental, and task constraints. With a nonlinear pedagogy approach, the focus is on the individual learner where opportunities for meaningful actions can be learnt. Design principles based on representativeness, focus of attention, functional variability, manipulation of constraints, and ensuring relevant information-movement couplings can be delivered via pedagogical channels of instructions, practices, and feedback to the learners. Importantly, this focus on the individual sets the foundation for a developing nonlinear pedagogy framework to enhance teaching in PE although the challenges are non-trivial.  相似文献
