‘Pretty Lights’ and Maths! Increasing student engagement and enhancing learning through the use of electronic voting systems

University classes in Mathematics are traditionally perceived to be uninspiring and devoid of active student–lecturer communication. Large undergraduate classes further compound the difficulty of engaging students and enabling viable student–lecturer feedback. At the Mathematics Education Centre, Loughborough University, some staff members have been using electronic voting systems (EVS) to enliven the classroom and enable large numbers of students to respond to questions in real time during class. In this paper, we present an evaluation case study, based on student perceptions, of the impact of EVS use on student learning and engagement. The results show that majority of students are hugely positive about the usefulness and overall advantageousness of EVS use in classes. Results also show that EVS use does increase the likelihood of students participating and engaging in class, as even students who do not view EVS as being particularly useful stated that they are more likely to participate in classes where EVS are used than otherwise. However, there seems to be no correlation between EVS use and improvement (or otherwise) in student grades.

MHP‐OSGi convergence: a new model for open residential gateways

Nowadays, we are living in a time of important technological changes that affect our lives at home and our communication with the outside world. Among them, the developments in Interactive Digital TV (IDTV) and the smart home field can be considered as particularly important. Related to the former, the new Set‐Top Boxes (STBs) are not only a decoder for digital television broadcast but also an entry point to the Information Society and a suitable platform to support the execution of interactive applications. With regards to the latter, the Residential Gateways (RGs) combine different network technologies to allow the connection of different electronics devices and appliances at home, not only with each other but also with the Internet. Since there is no widespread consensus about the configurations and functions of the RGs, we propose to coordinate the two aforementioned worlds by extending the functionality of STBs to become a RG. Our proposal consists of merging the Multimedia Home Platform (MHP), one of the main standard frameworks for IDTV, with Open Service Gateway Initiative (OSGi), the most widely used open platform to set up RGs. To overcome the radically different nature of these specifications—the function‐oriented MHP middleware and the service‐oriented OSGi framework—we define a new kind of application, coined as XbundLET. This application is able to bridge the gap between the two frameworks and make their interaction feasible. We also show how this proposal has the potential to enable the production of scenarios that cannot currently be put into practice in a natural way. Copyright © 2006 John Wiley & Sons, Ltd.

SoC架构设计中的适应性扩展方法研究

为了应对SoC研发的机遇、困难和高昂花费,寻求对目标应用领域的最佳支持与广泛适用性之间的恰当平衡已成为目前电子系统设计的中心课题。通过一个从基于3G终端到网络多媒体播放器应用的架构扩展实例,重点论述了对SoC架构设计中适应性扩展方法的研究;另外,提出了一种基于IP的多处理器共享及层次结构存储体系,用以应对高密度的计算及传输任务需求;并通过系统级设计工具CoCentric,建立软硬件协同仿真平台,验证了本实例的扩展思路。     

Authorware5.0中调用IE浏览器的几种方法

在Authorware的参考书和其他相关文献中,都介绍有Authorware的文件调用函数,它可以调用.a5r、.exe等多种格式,但普遍都没有讲清楚、讲明白,只是把语法列出来,附以简单的说明,且没有对特殊程序调用的举例说明.本文就使用多种方法在Authorware中对InternetExplorer浏览器进行调用并打开某些Internet站点以及调用HTML格式文档等进行了详细介绍.     

Training for strategic decision making in professional contexts

Abstract The main new result reported in this paper is a computer-based approach for training strategic competences in practical jobs such as salesmen or waiters. The environment represents job situations in which the students may act from basic principles. The interaction is similar to that in simulations or microworlds, but there is no underlying model of the activity. In order to provide feedback to the learner, a model has been built which is based on the analysis of a large set of cases provided by experts. This model uses formal knowledge and contextual knowledge in order to build an explanation mechanism providing textual comments and multimedia illustrations.
