Noise Levels in Hong Kong Primary Schools: Implications for classroom listening     

Ching Yee Choi 《International Journal of Disability, Development & Education》2005,52(4):345-360

Many researchers have stressed that the acoustic environment is crucial to the speech perception, academic performance, attention, and participation of students in classrooms. Classrooms in highly urbanised locations are especially vulnerable to noise, a major influence on the acoustic environment. The purpose of this investigation was to determine noise levels in one such urban environment, Hong Kong. The ambient noise level, and its relationship to the speech intensity levels of both teachers and students was surveyed in 47 primary school classrooms. Moreover, the presence of acoustical treatments for noise reduction and the use of classroom amplification systems were documented for each classroom. The survey found that the mean occupied noise level was 60.74 dB (A); the mean unamplified and amplified speech‐to‐noise ratios of teachers were 13.53 dB and 18.45 dB, respectively; while the mean unamplified speech‐to‐noise ratio for students was 4.13 dB. Most of the classrooms exhibited insufficient acoustical treatments to provide significant noise reduction. The listening environment in many Hong Kong primary schools was not favourable for optimal classroom learning. Recommendations for improving the acoustical environment in classrooms in highly urbanised locations such as Hong Kong are discussed.  相似文献

新制度经济学视角下民办高职院校产教融合建设组织模式探究——以河北省某民办高职院校为例     

宋玉霞  辛磊  李钗 《教育教学论坛》2020,(11):348-349

长期以来,产教融合存在着“壁炉现象”和“集体主义困境”,文章从新制度经济学的视角,运用产权理论和交易费用理论分析问题成因,从组织模式建设层面给出解决问题的办法。让“双主体”变为“单主体”,采用股份形式的集团化组织模式能够提高产教融合的效能,提高资源的有效配置,并通过案例实证进行了路径探究。  相似文献

ON THE REE ACROSS THE PERMIANTRIASSIC BOUNDARY IN SOUTH CHINA     

Zhou Yaoqi Chai Chifang Mao Xueying Ma Shulan Ma Jiangguo 《中国科学院研究生院学报》1992,(2)

This paper discusses the INAA results of REE in clays atand near some Permian/Triassic boundaries of South China.It showsthat the REE patterns of boundary clays differ from those of non-boundary clays.One difference is that the boundary clays are moreenriched in LREE,with steeper slope of REE and a smaller Eu nega-tive anomaly than the non-boundary clays.Another difference is that theboundary clays show a small Ce negative anomaly,but no Ce anomalyoccurs in the non-boundary clays.From these REE patterns and some other experimental facts,it isproposed that the P/T boundary clay may be a mixed product consistingof the acidic-intermediate ash and the upper crust substance representingsputtering component,and the calculated fraction of the former andlatter is 7/3.  相似文献

试论维州扭转唐蕃对峙局势的重要性     

柴学智 《兰台世界》2020,(2):135-138

安史之乱后,吐蕃乘唐朝内乱之机入寇唐王朝边境,掠西北、西南边地数十城,陷河陇,成唐王朝后期的最大边患。在唐蕃对峙时期发生的维州事件,作为牛李两党在边疆对外问题态度上显著分歧的重要表现,唐史学界历来有不同的看法。笔者认为,维州在唐蕃对峙中占有重要地位。结合唐王朝西北、西南边地形势的变化,唐王朝纳降维州,可以达到震慑吐蕃,使吐蕃遭受前后夹击,从而扭转唐蕃对峙局势的效果。  相似文献

关于地方民办教育制度创新的思考     

柴纯青 《教育发展研究》2011,(22)

我国一些地方政府在过去的几年中开始推进民办教育制度创新。文章基于对这些制度创新案例的研究指出,这些案例具有一些共同的特点,如地方政府具有改善公共服务的基本观念、直面民办教育发展中的关键问题,以及在地方政府力所能及的权限范围内进行改革。然而,这些创新还受到很多因素的制约,尤其是政府部门和公共学校形成的利益格局的阻力。同时,公众参与程度低、推动创新的人治力量太强也是其中的制约因素。因此,建立对创新的有效保障机制,是今后民办教育制度创新得以持续的关键。  相似文献
