Transformative Pedagogy: Emergent Bilinguals and Perspective Taking

This study contributes to the limited research on emergent bilinguals, perspective taking, and second language reading of informative text. The explicit integration of Freire’s (1993) notion of conscientizacao, or consciousness-raising, with the constructs of empathy and embodiment (Gee, 2001; Hurtado, 1996) and with translanguaging (García, 2009) represented conceptual frameworks that explicitly guided the pedagogical approaches implemented in the study. The findings indicated that the incorporation of the integrated conceptual frameworks with the prescribed fourth grade social studies curriculum enabled emergent bilinguals to generate their own perspectives concerning social justice and equity when studying about slavery in Texas.     

网络课程的学习适应初探

任何课程的学习都存在着学生与课程之间的适应问题。网络课程在面临普通课程适应问题的同时，还需要面临网络技术，网络环境，网络文化等因素对课程学习的诸多影响。网络课程的学习适应是一个多层次，复杂的认知适应过程，从网络课程的设计角度出发，文章提出，学习者与网络课程之间应该在课程观，课程技术和课程实践三个层次上相互适应。     

论我国紧急行政权的权力架构

在当代社会,紧急行政权是应对紧急状态所必不可少的手段,紧急行政权的构建和运行客观需要一个合理的权力结构予以分配规制。在这一权力分配结构下,紧急行政权才能发挥其有效的作用。笔者开篇讨论公共危机的现实存在,继而分析紧急行政权存在的合理性依据。最后从主体着手分四个层次详细论述我国紧急行政权的权力分配架构,希望通过理论论证能够为我国相关司法实践提供参考价值。     

Knowledge of the alphabet and explicit awareness of phonemes in pre-readers: The nature of the relationship

This study was carried out to examine the extent to which preschool children are aware of the phonemic structure of the spoken word and to investigate how they acquire that knowledge. The four year old non-readers carried out a battery of takss designed to assess product name reading ability, knowledge of the alphabet, rhyme skills and explicit phonemic awareness ability. There was evidence that they generally acquired knowledge of the alphabet before they showed explicit phonemic awareness ability. Fixed order regression analyses showed that ability to read and write the alphabet generally accounted for unique variance in phoneme awareness and product name reading ability over and above that accounted for by rhyme skills but that rhyme ability accounted for no unique variance beyond that accounted for by alphabet knowledge. Further analyses showed that alphabet knowledge also contributed unique variance to product name reading ability over and above that accounted for by phonemic awareness ability but that the reverse was not the case. It was hypothesised that many preschool non-readers may start to gain an insight into the phonemic structure of the spoken word by becoming aware of the connection between the sounds of letters in environmental print and the sounds of the spoken word.

移动学习的内涵、方式及其对远程教育的意义研究

计算机网络已经在教育和企业培训等领域得到广泛应用，并产生了新的学习方式——数字化学习（e-learning)。近几年来，随着无线通信技术的发展和移动计算技术的进步，一个新的概念——移动学习（m-learning)逐渐纳入人们的研究视野，与之相关的理论研究和实践项目正随之展开。本文主要对移动学习的概念，实施的形式以及移动学习对远程教育研究的理论意义等相关问题进行了系统阐述。     

Literacies across sponsorscapes: mobilising notions of literacy sponsorship

Building from the concept ‘sponsors of literacy', the authors revisit three empirical studies to argue for mobilising notions of sponsorship beyond fixed conceptions of individual sponsors and literacy to lifewide perspectives that take into account sponsoring relations across the broader learning lives of youth. The authors take up the theoretical heuristic ‘sponsorscapes' as a lens for attending to the dynamically networked, reciprocal and human‐material dimensions of literacy practices. With cases drawn from across settings and research foci, including middle school students in a classroom setting, high school‐aged youth across contexts and a participant‐researcher's interactions with a college student, the authors argue that attending to sponsorscapes can contribute critical insight into the emergent, diverse and valued literacies and sponsorship thriving across lifewide learning pathways, while recognising learners' agentive roles in investing, resisting and sponsoring literacies.     

Liberating data for public value: The case of Data.gov

Public agencies around the globe are liberating their data. Drawing on a case of Data.gov, we outline the challenges and opportunities that lie ahead for the liberation of public data. Data.gov is an online portal that provides open access to datasets generated by US public agencies and countries around the world in a machine-readable format. By discussing the challenges and opportunities faced by Data.gov, we provide several lessons that can inform research and practice. We suggest that providing access to open data in itself does not spur innovation. Specifically, we claim that public agencies need to spend resources to improve the capacities of their organizations to move toward ‘open data by default’; develop capacities of community to use data to solve problems; and think critically about the unintended consequences of providing access to public data. We also suggest that public agencies need better metrics to evaluate the success of open-data efforts in achieving its goals.     

空间信息系统支持下的三峡库区土地利用时空变化分析

论文利用近50年来长序列统计资料对赤峰市耕地动态变化进行了研究，结果发现：1950年-2000年赤峰市耕地总量经历了3个增长期和2个减少期；耕地变化除具有以全市总量变化为代表的普遍特征外，南部和中北部具有明显的区域差异，主要表现为，50年来，与中北部各旗（县）相比，以敖汉旗为代表的南部3旗（县）耕地相对变化率较小，但1961年-1990年耕地减幅较大；通过文献调研和定量研究得知，50年来赤峰市耕地变化主要受5次大的政策因素驱动，并与人均国内生产总值、总人口、年末牲畜存栏总头数、粮食单产和人均粮食占有量等人口和经济发展因素显著相关。
