中度弱智儿童句法结构状况初步考察

以辅读学校18名二、三年级中度弱智儿童在校一个月交际语中的部分句子作为研究样本,从汉语句法结构角度对所获样本进行分析考察,以求对这类儿童的句法能力及其偏误做出分析与评价,目的是了解这一特殊群体汉语句法习得的机制、发展状况及发展潜能,以期对中度弱智儿童的句子教学与训练提供依据.     

远程开放教育环境下开展探究式教学的探索

现代远程开放教育以培养应用性高等专门人才为目标,改革教学模式是关键。在各种教学模式中,探究式教学更能体现远程开放教育的特点,更适合培养高素质的应用性人才。本文论述了探究式教学的基本特征,开展探究式教学的基本模式及需要重点注意的几个问题。     

以分享为特征的网络学习社群研究

近年来,利用网络学习社群学习受到越来越多网络学习者的欢迎。网络学习社群的成员分散在不同区域,藉由因特网相互沟通、学习并且完成群组工作,以达到学习的目的。本文介绍了网络学习社群的基本特点、使用注意事项,同时提出方案,解决网络学习社群中分享知识遇到的障碍。     

由黄河断流引发的相关法律制度建设思考

黄河连续多年断流,反映出人、河之间整体上缺乏有效的制度约束,导致黄河流域地表集水环境退化、水分涵养能力降低,危害严重.为此,必须建立法律调控制度,通过土地使用权、公益诉讼权、用水优先权和水资源补偿等制度的设定,重建黄河管理机构等,发挥权利的激励与义务的约束作用,把治理断流、缩小区域经济差距与促进流域内经济可持续发展结合起来,实现人河永续共存之目的.     

Training in phonological strategies improves Chinese dyslexic children’s character reading skills

This study investigated Chinese dyslexic children’s efficiency in employing phonological strategies (i.e. the use of orthography-phonology correspondence rules) in reading and the effectiveness of training phonological strategies in improving Chinese dyslexic children’s reading performance. An Experimental Group of 15 Chinese dyslexic children received a five-day intensive training in phonological strategies while a comparable Control Group did not. The results showed that Chinese dyslexic children did not use the phonological strategies as efficiently as Chinese average readers, and the training programme was effective in significantly improving the Experimental Group’s reading performance. This suggests that Chinese dyslexic children can benefit from training in phonological strategies.     

论济南在全省区域经济协调发展中的功能与作用

济南作为山东省省会城市和省域性中心城市,在山东省区域经济协调发展中具有重要的战略地位,但要充分发挥济南对全省区域经济协调发展的带动作用,必须对济南的中心城市功能予以明确定位,并通过各种战略举措促进这一功能目标的实现。     

对近代中国出路的早期探索的启示

五四运动爆发前,在中国逐渐沦为半殖民地半封建社会的进程中,为了实现民族独立和国家富强,地主阶级、农民阶级、资产阶级等不同的社会力量都进行了不同的探索,提出了不同的救国方案。但无论是农民阶级自发的反帝反封建斗争,地主阶级的洋务运动,还是资产阶级建立西方式资产阶级共和国的努力,都无法实现中国的民族独立和国家富强,这些探索先后以失败告终。历史证明,只有在中国共产党的领导下,在马克思主义理论的武装下走社会主义道路,中国人民追求民族独立和国家富强的目标才能够真正实现。     

Air Plasma-Activated Crosslinking of Low-Density Polyethylene During Melt Mixing

In this work,air plasma surface treatment followed by oxidation in an atmospheric environment was used to generate activated low-density polyethylene(LDPE) with oxygen-containing functional groups and peroxide radicals.The resulting samples were then studied by using attenuated total internal reflectance-Fourier-transform infrared spectroscopy,X-ray photoelectron spectroscopy,and the 2,2-diphenyl-1-picrylhydrazyl method.Peroxide radicals are generally considered active substances which can initiate the crosslinking reaction.Melt mixing of the surface-treated LDPE allowed activated polymer chains with peroxide radicals to initiate the crosslinking reaction,and the maximum gel fraction obtained was 4.1%.The rheological behaviors,including viscosity,storage and loss moduli,loss tangent,and Cole-Cole plots,of the slightly crosslinked LDPE were studied,and the results of tensile experiments revealed that the formation of slightly crosslinked structures can improve yield and fracture stresses without sacrificing the breakage strain.
