国际经验对建构中国教师教育新体系的启示

网络化时代的到来、全球经济的发展、知识经济的出现呼唤国际性和创新型人才。中国“普九”任务基本完成。基础教育课程改革深入开展，使以提高教师实施素质教育的能力和水平为重点的教师专业化走向新历程。这是中国教师教育新体系构建的时代背景。国际教师教育经验为建构中国教师教育新体系提供了启示。     

中学生网络成瘾探析

中学生使用网络,迷恋网络,主要受兴趣、好奇心、社会交往、自我实现以及外在等因素的驱使.通过对迷恋者培养积极兴趣创造成功体验、建立正确的自我评价认知范式、集体治疗及网络厌恶的干预手段,使他们正确使用网络而不至于成瘾.     

建筑风景画的美学品格与文法范式

建筑风景绘画样式除了各种表现策略外,还有自身的文法范式及构成它自身的表意元素.学习和掌握建筑风景画,有利于提高建筑表现图画的专业表达能力;通过准确反映甚至强化建筑设计意图,增强对建筑、自然的了解,可为建筑设计积累专业素材和专业养分.在绘画表现中,真正掌握建筑风景画的文法范式,对提高建筑风景的审美品格与价值有着十分重要的现实意义.     

对高职高专类学校公共政治课教学的思考

公共政治课是高职高专类学校的一门必修课。由于公共政治类课程本身的特点以及实施本门课程教学的主观目的与学生客观需求之间存在较大差异,出现教师难教、学生难学、教学质量低的现象。结合这些客观实际,必须将“实、活、准、精”的原则贯彻到课堂教学中。     

美国虚拟特许学校的运行机制述评

虚拟特许学校是虚拟学校与特许学校的结合体,反映了美国最新的教育改革动向。其办学主体较为多元,需满足特定的办学资质要求并获取相应的授权。而且虚拟特许学校的生源具有门槛较低、来源多样的特点,学生学费主要由政府资助。他们所采取的是市场化的教学运营系统,其课程通常交由第三方公司编制,通过网络平台提供个性化的教学,并对学生的学业状况进行动态监控。虚拟特许学校的评价体系包括质量导向的政府评价、优胜劣汰的市场评价和丰富多样的社会评价等。     

How much does lower body strength impact Paralympic running performance?

Objectives: Development of evidence-based methods of Paralympic classification requires research quantifying the relative strength of association between ratio-scaled measures of impairment and athletic performance. The purpose of this study was to quantify the extent to which muscle strength affects running performance in runners with and without brain impairment. Design: Cross-sectional study. Methods: Participants were 41 male runners: 13 with brain impairments (RBI) and 28 non-disabled (NDR). All participants completed a maximal 60-m sprint and a novel battery of three lower limb isometric strength tests. Results: RBI showed significantly lower strength scores compared with NDR on the more affected side in leg flexion (176 vs. 243?N), leg extension (993 vs. 1661?N) and plantarflexion (824 vs. 1457?N). Significant differences were also seen on the less affected side in plantarflexion (1072 vs. 1508?N). RBI were significantly slower in the acceleration phase (0–15?m) (3.2?s?±?0.3?vs. 2.8?s?±?0.2) and top speed phase (30?60?m) (4.3?s?±?0.6?vs. 3.8?s?±?0.3). Correlation analysis showed stronger relationships between strength and running performance in RBI than NDR; however, the correlations were not significant. Conclusions: This study evaluated measures to assess strength for the purposes of classification and found that the measures were significantly different in RBI compared with NDR indicating the tests were able to capture strength impairment in this population. This study indicates that strength may be an important impairment type to assess in this population, as impairments of muscle strength may influence the outcome of running performance in athletes with more severe impairments.     

One hundred and fifty years of sprint and distance running – Past trends and future prospects

Sprint and distance running have experienced remarkable performance improvements over the past century. Attempts to forecast running performances share an almost similarly long history but have relied so far on relatively short data series. Here, we compile a comprehensive set of season-best performances for eight Olympically contested running events. With this data set, we conduct (1) an exponential time series analysis and (2) a power-law experience curve analysis to quantify the rate of past performance improvements and to forecast future performances until the year 2100. We find that the sprint and distance running performances of women and men improve exponentially with time and converge at yearly rates of 4% ± 3% and 2% ± 2%, respectively, towards their asymptotic limits. Running performances can also be modelled with the experience curve approach, yielding learning rates of 3% ± 1% and 6% ± 2% for the women's and men's events, respectively. Long-term trends suggest that: (1) women will continue to run 10–20% slower than men, (2) 9.50 s over 100 m dash may only be broken at the end of this century and (3) several middle- and long-distance records may be broken within the next two to three decades. The prospects of witnessing a sub-2 hour marathon before 2100 remain inconclusive. Our results should be interpreted cautiously as forecasting human behaviour is intrinsically uncertain. The future season-best sprint and distance running performances will continue to scatter around the trends identified here and may yield unexpected improvements of standing world records.

论《平凡的世界》的史诗性特征

重读《平凡的世界》,仍然有一种强烈的穿越感,作品所反映的社会生活内容依然能够唤醒我们沉睡的记忆,引发精神上的强烈震撼。《平凡的世界》之所以今天仍然能够力透纸背,层层扩散波光,让人读懂、读出社会历史内涵,其根本原因在于小说真正切入现实,以及作者的史诗性写作和作品的史诗性特征。小说书写的农村改革史、农民创业史和青年奋斗史正好体现了20世纪80年代社会、家庭、个人等层面的发展、成长的历史。作品由双水村、石圪节到黄原、铜城大牙湾,由农村到城市,反映出了一个时代整体的社会风貌,具有丰富的史诗性价值。
