Implementing embodied learning in the classroom: effects on children’s memory and language skills

The relationship among bodily movements, cognitive abilities, and academic achievement in children is receiving considerable attention in the research community. The embodied learning approach is based on the idea of an inseparable link between body and mind in learning, aiming for teaching methods that promote children’s active engagement in the classroom. This study implements embodied learning as a part of the classroom curriculum in a real classroom environment using motion-based games. A total of 52 elementary students engaged in embodied learning in-class activities for four months. The data-set included standardized pre-post testing for children’s cognitive and academic performance, general learning analytics from games’ usage, interviews, and observations from the teachers involved. Findings showed significant effects both on children’s cognitive abilities (i.e., short-memory skills) and academic performance (i.e., expressive vocabulary). This article contributes to the educational technology community by providing an example of implementing embodied learning via use of motion-based technologies in a real classroom environment.

中国共产党统筹兼顾方针的历史考察

从历史上看,统筹兼顾方针是中国共产党重要历史经验和历来的战略方针。统筹兼顾思想在抗日战争初期首先从政治上提出,建国初期确立为经济指导方针,后来确定为我国社会主义建设指导方针。统筹兼顾方针在社会主义建设新时期有两次重大发展,增添了新内涵;进入新世纪新阶段后又与科学发展观相结合,并通过“五个统筹”、“五个坚持”的统一,形成新理论,实现飞跃发展。     

电子商务网站的策划和推广

在信息经济时代，电子商务是企业发展的必由之路。企业如何进入电子商务领域呢?首先，具备条件的企业应尽早构建电子商务管理的体系与结构，具体地说，就是创立企业自己的Intranet平台，并建立企业内部资源管理系统(ERP)，这是企业进入电子商务的基础，其次再建立企业网站，连接到Incernet上，实现电子商务。电子商务网站建设成功与否，是电子商务价值最终结果的成败所在。

A new quantitative model of ecological compensation based on ecosystem capital in Zhejiang Province, China

Ecological compensation is becoming one of key and multidiscipline issues in the field of resources and environmental management. Considering the change relation between gross domestic product (GDP) and ecological capital (EC) based on remote sensing estimation, we construct a new quantitative estimate model for ecological compensation, using county as study unit, and determine standard value so as to evaluate ecological compensation from 2001 to 2004 in Zhejiang Province, China. Spatial differences of the ecological compensation were significant among all the counties or districts. This model fills up the gap in the field of quantitative evaluation of regional ecological compensation and provides a feasible way to reconcile the conflicts among benefits in the economic, social, and ecological sectors.

兰州大气细颗粒物中有机碳与元素碳的污染特征

采集兰州冬季采暖期及夏季PM_2.5样品共60个,通过DRI 测定有机碳(OC)和元素碳(EC). 结果显示:冬季OC和EC平均质量浓度分别为(35.39±13.88)μg/m³和(13.80±5.41)μg/m³,夏季分别为(9.74±3.30)μg/m³和(4.44±2.00)μg/m³,冬季污染远高于夏季. 冬夏季OC和EC相关系数分别为0.91和0.76,表明冬季兰州PM_2.5中OC和EC的来源相似. 二次有机碳质量浓度冬夏季分别为(8.48±6.10)μg/m³和(3.07±2.20)μg/m³,约占OC含量的(22.46±11.93)%和(31.29±18.51)%,表明兰州冬夏季PM_2.5中OC的来源均以一次排放为主,夏季二次源贡献高于冬季. 对8种不同温度段碳质组分分析表明,兰州冬季生物质燃烧较夏季有所增加,夏季可能主要为机动车尾气.
