日常家庭生活中父母——儿童互动对儿童数学发展的影响

本研究观察并分析了两组4岁儿童在家庭日常生活中与父母的互动及所涉及的数的学习。组1儿童为书面数符号表征高分者，组2儿童为低分者。57对儿童-父母对子参加了研究。结果表明，本研究所观察到的儿童日常活动内容丰富多样；大概有三分之一的被试对子所从事的活动涉及到不同类型的阅读和数学学习活动，但这些活动大多由父母发起；儿童早期数学发展水平可能与家庭教育的如下因素有关：家庭日常生活中父母-儿童共同活动的内容与频次，高分组儿童的父母在家中可能更加注意发起或者更加成功地发起了阅读与数学学习活动；高分组父母在与儿童互动的某些策略的运用上可能更有利于儿童的数学学习；高分组的父亲在家中可能与孩子一起参与共同活动的时间更长；高分组父母之所以更加成功地发起了与阅读和数学学习有关的活动可能与儿童本身的因素有关。     

Assessing term effectiveness in the interactive information access process

This study addresses the question of whether the way in which sets of query terms are identified has an impact on the effectiveness of users’ information seeking efforts. Query terms are text strings used as input to an information access system; they are products of a method or grammar that identifies a set of query terms. We conducted an experiment that compared the effectiveness of sets of query terms identified for a single book by three different methods. One had been previously prepared by a human indexer for a back-of-the-book index. The other two were identified by computer programs that used a combination of linguistic and statistical criteria to extract terms from full text. Effectiveness was measured by (1) whether selected query terms led participants to correct answers and (2) how long it took participants to obtain correct answers. Our results show that two sets of terms – the human terms and the set selected according to the linguistically more sophisticated criteria – were significantly more effective than the third set of terms. This single case demonstrates that query languages do have a measurable impact on the effectiveness of query term languages in the interactive information access process. The procedure described in this paper can be used to assess the effectiveness for information seekers of query terms identified by any query language.     

低碳发展方案编制指南(第三部分)——制定低碳发展规划

本节介绍制定低碳发展计划常用的核心步骤。本指南侧重城市层面;同样的步骤也适用于企业、市、省和国家等层级。中国自"十一五规划"起,对改善国内能源强度定出目标,包括各经济部门的节能目标。2009年12月中国政府公布了其碳强度目标,重点放在单位GDP用能引发的二氧化碳排放量。为实现该强度目标以及"循环经济"等经济性目标,制定低碳发展规划尤其必要。     

Children’s Participation in a Virtual Epidemic in the Science Classroom: Making Connections to Natural Infectious Diseases

This study investigated students’ understanding of a virtual infectious disease in relation to their understanding of natural infectious diseases. Two sixth-grade classrooms of students between the ages of 10 and 12 (46 students) took part in a participatory simulation of a virtual infectious disease, which was integrated into their science curriculum. The results from our analyses reveal that students perceived the simulation as similar to a natural infectious disease and that the immersive components of the simulation afforded students the opportunity to discuss their understandings of natural disease and to compare them to their experiences with the virtual disease. We found that while the virtual disease capitalized on students’ knowledge of natural infectious disease through virtual symptoms, these symptoms may have led students to think of its transfer more as an observable or mechanical event rather than as a biological process. These findings provide helpful indicators to science educators and educational designers interested in creating and integrating online simulations within classroom environments to further students’ conceptual understanding.     

高校学生党员在学风建设中作用发挥机制研究

学风建设是高校提高教育教学质量的根本保证,是高校加快建设和不断发展的重要基础.搞好高校学风建设要充分发挥学生在学风建设过程中的主体作用,要高度重视学生党员在学风建设过程中的作用发挥.学生党员是推动学风建设的主力军,是培养优良学风的有力抓手.要在实践中不断健全机制,形成充分调动学生党员在学风建设中的主动性、积极性和创造性的机制,争取促进学生党建工作和高校学风建设,不断推动高等教育健康快速发展.     

小学四、五年级学生数学学习策略水平的调查研究

一、引言自上世纪90年代以来,学习策略的研究日益受到国内教育心理学研究者的重视。大量的研究表明,良好学习策略的使用能有效地提高学生的学习水平。了解学生学习策略的使用情况,帮助他们掌握并使用有效的学习策略,已成为当前教师、家长和学生本人非常关心的问题,也是摆在我们教育界和心理学界研究者面前的一项任务。     

Early numeracy in low‐performing young children

The aim of this study was to explore the early numeracy of low‐performing young children. The mean age of the children was six years and four months. The 511 participants belonged to three groups: multi‐language children, children with special educational needs and children with average performance. The results showed that there were significant group differences in early numeracy: the children in the reference group had better relational and counting skills than those with a multi‐language background and those with special educational needs. Some differences were found in counting skills between the children with multi‐language background and those with special educational needs. Finally, (special) educational support for low‐performing children is discussed.     

从白金预认证到三星级:中美绿色建筑分等评级程序的比较分析

2011年,作为全球最大能源使用国以及二氧化碳排放国,中美的建筑业所消耗的能源分别占到全国能源总消耗量的25%和40%。在建筑节能领域,绿色建筑的出现为消除建筑业所带来的对能源以及环境的负面影响提供了解决方法。为了促进绿色建筑的市场转型,推进设计和施工的差异化,中美均制定了国家绿色建筑分等评级程序以及配套政策。1998年,美国绿色建筑协会首次推出能源与环境先导设计(LEED),而中国政府则于2008年建立了中国绿色建筑评价标识(GBEL)。本文对美国LEED与中国GBEL评级程序、流程、评分系统以及扶持政策作了对比分析,研究发现,虽然两国所采用的绿色建筑设计以及操作评级程序的评分等级较为相似,它们在项目管理、评分要求和分配以及扶持政策类型等方面存在差异。美国能源与环境先导设计是由建筑产业利益相关者委员会制定并实施管理的。判断是否达到认证水平的灵活性更高。中国绿色建筑评价标识则是由政府操控的。判断是否达到评级水平的要求更为严格。但是,中国政府将在2014年下半年对中国绿色建筑评价标识的评级程序作出修正。本文对评级程序以及扶植政策的相似点以及差异是如何影响绿色建筑技术以及市场的发展作了分析,还讨论了绿色建筑未来发展可能面临的挑战以及政策导向意义。
