关于幼儿园课程生活化的实践思考     

王莉 《陕西教育学院学报》2011,27(4):114-116

幼儿直观形象的思维特点,决定了幼儿园课程要以幼儿的生活经验为基础。因此,幼儿园课程只有生活化,才能有效促进幼儿的学习和发展。我园在实施课程生活化的实践探索中,总结出了几点课程与生活有效整合的经验,即创设生活化的环境;重视幼儿对生活的体验和感悟;让幼儿在生活中自主探究发现;锻炼幼儿掌握生活技能;在社区中拓展生活视野;培养幼儿亲自然、亲社会的人文情感。  相似文献   

会意字与义素分析     

曹国安 《惠州学院学报》2011,31(1):67-70

会意字不是造字者随随便便捡几个相关的字或符号凑在一起从而造出来的,而是造字者经过义素分析之后精心挑选有关字符组装而成的。这说明,会意字的产生经历了义素分析这一过程。而义素分析属于析义,因此,会意字的产生经历了析义阶段。义素分析法并非现代西方人首先发明的,而是古代中国人首先发明的。中国人首先发明并使用义素分析法,比西方人提出并使用义素分析法要早三千多年。  相似文献   

基于组合评价的高校专利竞争力研究——以福建省本科高校为例          下载免费PDF全文

王启超  刘旭俐  刘敏榕 《情报科学》2020,38(1):109-115

【目的/意义】为了促进高校的专利评价能力,更好地服务高校专利工作的推进,建立一种基于组合评价的 专利竞争力评价模型,对高校专利竞争力进行客观评价与认识。【方法/过程】将主成分分析法与熵权法结合,利用 模糊Borda法进行组合评价,并以福建省19所本科高校为例,进行专利竞争力评价分析。【结果/结论】为高校专利 竞争力的评价提供了新思路。评价结果表明,福建省高校专利竞争力整体差距较大,多数高校没有平衡好专利数 量、专利质量与价值的关系,缺乏合理规划。根据评价结论,提出了相应的建议。  相似文献   

Light-load maximal lifting velocity full squat training program improves important physical and skill characteristics in futsal players     

Julio Torres-Torrelo  Juan José González-Badillo 《Journal of sports sciences》2017,35(10):967-975

This study aimed to compare the effect of 6 weeks of resistance training or combined resistance training and change of direction exercises on physical performance and motor skills in futsal players. Thirty-four futsal players were divided into full squat group (SG, n = 12), combined full squat and change of direction exercises group (S+CDG, n = 12) and control group (CG, n = 10). The resistance training for SG consisted of full squat with low load (~45–58% 1RM) and low volume (4–6 repetitions), whereas the S+CDG performed the same resistance training program combined with loaded change of direction. Sprint time in 10 and 20 m, change of direction test, countermovement vertical jump (CMJ) height, maximal strength and force–velocity relationship in full squat exercise, kicking speed ball (BS_mean) and repeated sprint ability (RSA_mean) were selected as testing variables. Both experimental groups showed significant improvements for CMJ, BS_mean and all strength parameters. Only SG resulted in significant sprint gains, whereas S+CDG also achieved significant improvements in RSA_mean. The CG remained unchanged after training period. No significant differences were found between both experimental groups. These findings suggest that only 12 sessions of either lightweight resistance training alone, lifting the load at maximal intended velocity or combined with change of direction exercises is enough to improve several physical and skills capacities critical to futsal performance in adult players.  相似文献   

The power of circulation: digital technologies and the online Chinese fans of Japanese TV drama     

Kelly Hu 《Inter-Asia Cultural Studies》2013,14(2):171-186

Focusing on the online Chinese fans of Japanese TV drama, this paper explores the way in which the fan subculture, in connection with digital technologies, has carved out alternative practices in the circulation, production and consumption of Japanese TV drama. As ‘minority audiences’ who are not targeted as the objects of capitalist interests, online Chinese fans invent spaces for Chinese transnational networking with self‐help and sharing, as a way of resisting the aloofness from marketing strategies of Japanese TV distributors in Asia. This case study reveals that the online Chinese fan clubs, the websites for downloads, pirated VCD markets, digital file conversion, and private VCD burning – all of these have linked endless networks for the digitalized circulation and consumption of Japanese TV drama. The online Chinese fans are guerrilla fighters in the politics of autonomy, network and low‐cost digital technology; they are attempting to break down time–space constraints and the official distribution hierarchy. Such fan practices shed light on the new trends of audio‐visual consumption via digitalization.  相似文献
