Co-design for an SoC embedded network controller

INTRODUCTION With the development of Ethernet systems and the growing capacity of modern silicon technology, embedded communication networks are playing an increasingly important role in embedded and safety critical systems. Advances in VLSI technology have also pushed integration to the point where it is now possible to design and implement a microprocessor and network controller on a single chip, known as System-on-Chip (SoC). In a network of embedded systems, each system can communi…

嵌入式学习:后PC时代的数字化学习

在PC时代,数字化学习是基于个人电脑和有线网络的。随着信息技术的发展,数字化学习将向基于嵌入式系统和无线网络的后PC时代扩展。数字化学习将在后PC时代得到新的阐释,并由此产生一种新的学习模式棗嵌入式学习(Embedded Learning)。     

论网络广告的投放策略

网络媒体的特性决定了网络广告在传播方式、传播效果与传统媒体广告的不同,同时也使消费者对网络广告信息传播的接受方式、接受效应产生很大的差异。从三大门户网站上广告投放情况来看,当前网络广告的形式日趋多样化,但作为出现不久的新事物,网络广告存在着一些问题,还需要一段时间去发展去完善。对于提高网络广告投放效果．我们可以从网络广告投放位置、投放时段、广告形式的选择等方面入手加以分析利用。     

Embedded Library Services: From Cooperation to Collaboration to Enhance Student Learning in Asynchronous Online Course

The online environment presents a unique challenge to higher education. Shifting from the face- to-face format to online not only involves rethinking course design, but requires careful consideration of when and how to teach students, how to find and evaluate information needed to successfully complete coursework. One solution is faculty teaming with subject librarians to design and build in teachable moments. This case study discusses one such successful partnership from designing the course to choosing and embedding library resources and finally to the learning outcome of the online course.     

浅议当前社会分化的基本动力——以卡尔·波兰尼"嵌入"理论为视角

当前中国社会分化的动力呈现出三种不同经济形态各自作用又相互影响的特点,这种机制导致了社会分化的动力同社会转型的动力缠绕在一起,国家在处理社会分化问题上面临着两难选择。

基于嵌入式视频服务器的教学评估系统

教学评估是教学管理中重要的环节之一。随着高校规模的迅速扩大和教育教学模式的改变,特别是多校区教学活动的展开和多媒体教学方法的运用,对教学评估工作提出了新的要求。文章依托学校现有的数字化教学环境,通过对教学过程评估工作需求的分析,提出了构建"基于嵌入式视频服务器的教学评估系统"的总体框架和设计实现方案。     

Scaffolding Learning through Meaningful Tasks and Adult Interaction

This paper reports a study into the role of a supporting adult in promoting effective learning relating to aspects of 3D shape in young children. Nursery and reception aged children carried out problem solving tasks using wooden blocks, in this case Poleidoblocs, embedded within playful contexts. Using the notion of 'scaffolding' and working within the child's Zone of Proximal Development, this study analyses the structured adult intervention that increases the effectiveness of learning and leads to an enhanced development of secure and transferable concepts.
