What is an ecological approach and how can it assist in understanding ICT take-up?

This paper argues that ecological frameworks offer a powerful way of explaining the take-up of information and communication technology (ICT) in schools. Past research has focused on teachers and their willingness and readiness to use ICT but this has not satisfactorily explained the use (or non-use) of ICT. Gaps in this research can be addressed by an ecological approach which shifts attention from the teacher to the context in which ICT is expected to be used. Such an approach, following Bronfenbrenner and others, looks at the relationship of individuals to the system in which they act, a relationship which is seen as interdependent. An ecological perspective explains how take-up of ICT is influenced by the degree to which different levels of a system, eg, micro, meso, exo and macro levels, are aligned. It is recommended that researchers and policy makers should pay greater attention to context when advocating the use of ICT.     

Numerical competence in young children and in children with mathematics learning disabilities

A longitudinal study was conducted on 82 children to investigate, firstly the numerical competence of young children and the predictive value of (pre)-numerical tests in kindergarten, and, secondly, whether children's knowledge of the numerical system and representation of the number size is related to their computation and logical knowledge and to their counting skills. In an additional cross-sectional study on 30 children with a clinical diagnosis of mathematical learning disability (MLD) of 8,5 years, age- and ability-matched with 2 × 30 children the same parameters of numerical competence were assessed. The longitudinal data showed individual differences in numerosity, as well as the relationship between a delay in arithmetics in grade l and problems on numerosity in kindergarten. In the cross-sectional results some evidence was found for the independence of numerical abilities in MLD-children. About 13% of them had still severe pre-numerical processing deficits (in number sequence production, cardinality skills and logical knowledge) in grade 3. About 67% had severe difficulties in executing calculation procedures and a lack of conceptual knowledge. A feature of 87% of the MLD-children was severe translation deficits, with a significantly worse knowledge of number words compared with the knowledge of Arab numerals. Finally a severe deficit in subitizing was found to be present in 33% of the MLD children. On a group level the processing deficits were linked to understanding numerosity, since the ability-matched younger children and the MLD-children had the same pre-numerical and numerical profile. Implications for the assessment of mathematical disabilities and the value of TEDI-MATH® as an instrument in this process are discussed.     

从文学期刊看四十年代通俗文学的发展流变

文学期刊作为文学作品发表的舞台和阵地对一个时代的文学取向和发展有着很大的影响力。通过对四十年代一些文学期刊的考究能发现它们在“解放区”、“沦陷区”、“国统区”三区并存的时局下各自办刊宗旨的时代演变,以及在抗日战争、解放战争时期的新变,进而来探讨在这样一个时代背景下的通俗文学的发展流变。     

从《雷峰塔》、《易经》看张爱玲的家庭叙述及创作动机

张爱玲新近出土的《雷峰塔》、《易经》延续了其一贯的家庭叙述。而这两部作品所叙述的内容,几乎在她早期的作品中都有所涉猎。她不断重复书写的动机何在？通过对其生平梳理和文本解读,可归纳为以下几点：消解家族在＂族谱＂意义上的崇高以及在＂血缘＂意义上的温情;从个人潜在的心理因素上来说,这种书写还是一种＂复仇＂,向曾带给她身心伤害的整个家族的＂报复＂;从弗洛伊德精神分析理论来看,又包含了以此来减轻自己童年的痛苦以及找寻自己存在的意义两方面的动机;以及期待打开美国市场,书写旧日＂传奇＂;缓解写作焦虑,寻找写作灵感。     

新课改背景下教学文化的转型与建构

在新课程推行过程中,新旧课程、新旧教学产生各种冲突,阻碍教育教学的发展。而这些冲突实质上是新旧教学文化之间的冲突。新型教学文化的模式构建在研究其理论和实践的基础上,迎合新课程的改革理念而成型,对新课程的实施和推进,对教学文化的深入研究都有着重要意义。     

赛博学习：学习科学创新发展的新战略支点

废塑料（聚苯乙烯）的改性利用

采用多种常用的氧化剂对废塑料（聚苯乙烯）进行化学处理,可获得制造油漆的原料。本文在延续与拓展以前研究的基础上,以改性的废聚苯乙烯作为基料,再添加各种填料制成涂料,使涂料的燃烧性能大大降低,同时也证明了用硝酸-硫酸作氧化剂改性后的废塑料具有一定的爆炸性。     

从客家变迁中的体育文化发展趋势看传承机制构建--以“客都”梅州为个案

采用文献资料法,实地考察法,问卷调查法等研究方法,对梅州地区客家体育文化的变迁从历史渊源,现实状况,未来发展趋势三方面进行探讨,指出了客家体育文化在变迁中的面临的现实问题,有针对地提出成立实体和虚拟博物馆,加强客家宗族联盟建设,客家体育进课堂,成立世界客家体育分会等建议以实现客家体育文化传承的延续性,利于构建客家体育文化传承机制。     

传统武术传承与变迁的文化探骊

传统武术是中国一项传统的身体技艺。它有着自己独特的文化价值观念和传承模式,并具备焕发时代功能的文化传统。文章运用文献资料、逻辑分析、归纳演绎等方法,来解析其存在的文化价值和意义。研究认为,传统武术在传承活动中,应结合三模式的优势,发展三位一体的传承模式,即家族、师徒、师生模式并用,以图最大范围的传播传统武术的身体技艺。在传播手段上,需根据社会认同感,适度作出调整,使自身的传播手段更为多元,提高大众对其的文化认同度。     

人事管理系统与考勤机接口实现研究

考勤作为一个单位的基础管理,越来越受到重视,传统的考勤模式为人工考勤,人工考勤靠专人书面登记,存在许多主观、人为因素,往往最终不能令管理层取得真实的考勤结果资料,甚至不能起到基本的约束作用。因此,人事管理系统结合具有专业性、安全性、独立性、实用性、完善性的彩屏指纹考勤机,对员工上下班的刷卡记录进行管理保存,形成员工真实的考勤数据,考勤管理人员将考勤数据下载到人事管理系统软件后,结合员工的基础信息进行匹配和处理,最后形成员工的考勤管理表。对人事管理系统结合考勤机实现考勤管理进行了研究,并对系统考勤管理功能模块进行了分析与设计。人事管理系统与考勤机接口的实现,有利于人事管理中考勤管理的正确性、公正性和公开性,并解决了传统手工签到管理中所存在的问题。
