中美基础教育课外体育活动的比较研究

运用文献资料法、访谈法、比较分析法和逻辑法，对中美基础教育课外体育活动的价值取向、政策文件、组织管理、场地设施、运动时间及实施效果进行梳理、分析和比较，从中得出以下启示：要坚持课外体育活动健身育人的价值；学校体育政策要向课外体育活动倾斜，并注重政策的落实；构建课外体育活动的三级体系，促进家校社三方联动；加快社区体育建设，引导体育消费升级；布置体育作业，保证课外运动时间；立足实际问题，让学生从课外体育活动中受益。以邻为镜比较优劣得失，但不能生搬硬套，要从传统体育文化中吸收养分，促进青少年身心健康，促进我国课外体育活动改革与发展。     

Expanding opportunities to learn to support inclusive education through drama‐enhanced literacy practices

This study examines how the Early Years Educators at Play (EYEPlay) professional development (PD) programme supported inclusive learning settings for all children, including English language learners and students with disabilities. The EYEPlay PD model is a year‐long programme that integrates drama strategies into literacy practices within real‐classroom contexts. Inclusive education refers to ensuring equal opportunities to access and participation in learning activities for all students. Cultural‐historical activity theory was used to understand and unpack the drama practices. Twelve semi‐structured focus group interviews were conducted with 19 preschool teachers. The data were analysed via constant‐comparative and interpretive methods. The study findings showed that EYEPlay PD practices enhanced inclusive learning settings for diverse groups of students by increasing access and expanding opportunities to learn, and supporting a positive learning environment.     

Fatigue increases ankle sprain risk in badminton players: A biomechanical study

ABSTRACT

Ankle sprains are the most common injury in regular badminton players and usually occur at the end of a match or training. The purpose of the present study was to examine the influence of fatigue produced by badminton practice on the lower limb biomechanics of badminton players. It was hypothesized that fatigue induces ankle kinematic and lower leg muscle activity changes which may increase the risk of ankle sprain. Ankle kinematics, ankle kinetics and muscles activities of 17 regular badminton players were recorded during lateral jumps before and after an intense badminton practice session. Post-fatigue, ankle inversion at foot strike and peak ankle inversion increased (+2.6°, p = 0.003 and +2.5°, p = 0.005, respectively). EMG pre-activation within 100 ms before foot landing significantly decreased after fatigue for soleus (?23.4%, p = 0.031), gastrocnemius lateralis (?12.2%, p = 0.035), gastrocnemius medialis (?23.3%, p = 0.047) and peroneus brevis (?17.4%, p = 0.036). These results demonstrate impaired biomechanics of badminton players when fatigue increases, which may cause a greater risk of experiencing an ankle sprain injury.     

The effects of school-based physical activity interventions on students' health-related fitness knowledge: A systematic review

This systematic review includes 34 studies examining the effects of school-based physical activity interventions on students' health-related fitness knowledge. The study design, methodological quality, and effectiveness of interventions on students' health-related fitness knowledge were analysed. The majority of the studies (79.4%) revealed significant positive intervention effects on students' health-related fitness knowledge. Studies examining adolescents were more frequently in a position to influence students' health-related fitness knowledge (87.5%) than studies examining children (75%), and studies with low methodological quality (88.8%) had more frequent positive effects than studies with moderate quality (75%). The effects on students' health-related fitness knowledge were independent of moderator variables such as the intervention content, duration and frequency. Only few studies were able to simultaneously positively influence students' health-related fitness knowledge and students' physical activity and/or fitness levels. These programmes can positively influence students' health-related fitness knowledge, but it remains unclear what the practical significance of these changes is. Further research is needed to clarify the influence of students' health-related fitness knowledge on reflection, understanding, physical activity behaviour, and overall physical literacy levels.

艺术的情境之寓——文艺美学探微

情境者,情趣境界之谓也,主于美。它存在于艺术作品中,也存在于整个艺术审美活动中。艺术没有唯一的和绝对的摹本,也没有终级价值标准,有的便是一件件具体的作品和一次次具体的活动。一件作品就是一个独绝的情境,这情境是别人创造不出的,甚至创造者自己都是不能重复的。在此情境中,包括每一个细部,即使如绘画中的一处空白,音乐中的一个休止,小说中的一段铺垫,等等,便有着特别的意味,特别的美质。     

论文学功能系统与特质

传统的作品功能观把本视为学功能的发生源，把读视为学功能作用的被动对象，本提出：学功能必须在具体的学活动中才能产生，学活动是学功能的发生源。学功能联系于学活动的动态开放整体的流程，并对投身于学活动的一切实践主体（作与读）产生系统效能，学功能系统由认知，净化，愉悦，生命四个各具丰富内涵的子系统构成，并通过系统质的审美化合指向人本身，指向人自身的丰富与完善，指向人的诗意人生，因此，学功能是学之人学本义的回归。
