论文学功能系统与特质   总被引:1,自引:0,他引:1  
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。  相似文献

用人单位要求毕业生具有很强的实践能力和适应能力。为使学生有很强的实践能力,实训教学不可或缺,而财经类院校的实训教学现状还不尽如人意,还需要进一步完善。具体思路是:转变观念,从战略高度认识实训教学;准确定位,找出符合自己学校实际的实训教学模式;完善管理,建立科学的实训教学体系;多管齐下,提高实训教学质量,充分发挥实训教学在人才培养中的作用。  相似文献

浮躁是一种危害极大、传染力极强的社会病、官场病。它既是形式主义和功利主义的表现,又是焦躁不安心态的折射。如不坚决刹住,势必严重削弱党员干部队伍的战斗力,损害党同人民群众的血肉联系,最终妨碍全面建设小康社会宏伟目标的顺利实现。采取坚决有效的措施,克服领导干部的这种不良习气,在当前显得尤其重要。  相似文献

在“邓小平理论和‘三个代表’重要思想概论”课的教学中,如何找到一条既能体现“两课”的导向作用,又使学生乐于接受的途径,成为“两课”教师经常讨论的问题。在实践中,我总结出了坚持以人为本的研究性学习,坚持社会实践活动是行之有效的途径。研究性学习内容丰富、形式多样,可以提高大学生思想理论素质、提高学生综合素质、锻炼能力。研究性学习需要有效的组织机制和学习制度保障。  相似文献

面对就业市场的激烈竞争,大学生必须具备相应的择业意识才能在竞争中抓住机遇,顺利完成择业过程。但在择业过程中,由于大学生缺乏择业法律意识卷入了择业的劳动纠纷。从维权意识、契约意识、公民意识和对违法行为性质的认识四个角度对大学生的择业法律意识进行分析。  相似文献

We hypothesised that resiliency may protect adolescents against risky behaviours, and that both the practicing of sports, and gender are moderating variables in relationships between resiliency and risky behaviours. The study included 18-year-old pupils from a selection of secondary schools (n = 556). A total of 188 individuals practiced competitive sports and the remaining 368 participants were non-athletes. The participants were examined with the Resiliency Assessment Scale for Children and Adolescents (SPP-18) and with a survey containing questions and statements related to high-risk “experiments with adulthood”. Adolescent athletes showed higher levels of resiliency than their peers. The power of the “Determination and Persistence in Action” effect on “Alcohol” scale differed significantly between male athletes and male non-athletes. Only in the athletes groups were higher scores on this scale reflected by lower values on the “Drugs” scale. Moreover, it is possible to observe differences in undertaking risky behaviour between male and female athletes. The analysis of risky sexual behaviour suggests that sport is a risk factor for men, and a protective factor for women. These data suggest that consistent prophylactic and psycho-educative activities, with a special attention to differences between genders, should be provided to all the adolescents, irrespective of their sport performance levels.  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献
