The impact of technology: value-added classroom practice: final report

This report extends Becta’s enquiries into the ways in which digital technologies are supporting learning. It looks in detail at the learning practices mediated by ICT in nine secondary schools in which ICT for learning is well embedded. The project proposes a broader perspective on the notion of ‘impact’ that is rather different from a number of previous studies investigating impact. Previous studies have been limited in that they have either focused on a single innovation or have reported on institutional level factors. However, in both cases this pays insufficient attention to the contexts of learning. In this project, the focus has been on the learning practices of the classroom and the contexts of ICT-supported learning. The study reports an analysis of 85 lesson logs, in which teachers recorded their use of space, digital technology and student outcomes in relation to student engagement and learning. The teachers who filled in the logs, as well as their schools’ senior managers, were interviewed as part of a ‘deep audit’ of ICT provision conducted over two days. One-hour follow-up interviews with the teachers were carried out after the teachers’ log activity. The aim of this was to obtain a broader contextualisation of their teaching

Connecting the World of Embedded Mobiles: The RIOT Approach to Ubiquitous Networking for the Internet of Things

The Internet of Things (IoT) is rapidly evolving based on low-power compliant protocol standards that extend the Internet into the embedded world. Pioneering implementations have proven it is feasible to inter-network very constrained devices, but had to rely on peculiar cross-layered designs and offer a minimalistic set of features. In the long run, however, professional use and massive deployment of IoT devices require full-featured, cleanly composed, and flexible network stacks. This paper introduces the networking architecture that turns RIOT into a powerful IoT system, to enable low-power wireless scenarios. RIOT networking offers (i) a modular architecture with generic interfaces for plugging in drivers, protocols, or entire stacks, (ii) support for multiple heterogeneous interfaces and stacks that can concurrently operate, and (iii) GNRC, its cleanly layered, recursively composed default network stack. We contribute an in-depth analysis of the communication performance and resource efficiency of RIOT, both on a micro-benchmarking level as well as by comparing IoT communication across different platforms. Our findings show that, though it is based on significantly different design trade-offs, the networking subsystem of RIOT achieves a performance equivalent to that of Contiki and TinyOS, the two operating systems which pioneered IoT software platforms

Becta Review 2005. Evidence on the progress of ICT in education.

Drawing on Becta national surveys of ICT use and implementation within the education system, the Becta Review identified the ways in which ICT could be used to support the DfES 5 year strategy, to introduce greater efficiencies in educational provision and more choice/personalisation of content and delivery

Buffering volatility : storage investments and technology-specific renewable energy support

Mitigating climate change will require integrating large amounts of highly intermittent renewable energy (RE) sources in future electricity markets. Considerable uncertainties exist about the cost and availability of future large-scale storage to alleviate the potential mismatch between demand and supply. This paper examines the suitability of regulatory (public policy) mechanisms for coping with the volatility induced by intermittent RE sources, using a numerical equilibrium model of a future wholesale electricity market. We find that the optimal RE subsidies are technology-specific reflecting the heterogeneous value for system integration. Differentiated RE subsidies reduce the curtailment of excess production, thereby preventing costly investments in energy storage. Using a simple cost-benefit framework, we show that a smart design of RE support policies significantly reduces the level of optimal storage. We further find that the marginal benefits of storage rapidly decrease for short-term (intra-day) storage and are small for long-term (seasonal) storage independent of the storage level. This suggests that storage is not likely to be the limiting factor for decarbonizing the electricity sector

Innovation, Learning and Cluster Dynamics

This chapter offers a theory and an analytical framework for the analysis of cluster dynamics, i.e. the innovative performance and evolution of clusters.It develops three types of embedding: institutional embedding, structural embedding (network structure), and relational embedding (type and strength of ties).The analysis is conducted from a perspective of both competence (learning) arising from relations and governance of relational risk, which includes risk of lock-in and risk of spillover.A basic proposition is that innovative clusters face the challenge of combining exploration and exploitation.Hypotheses are specified concerning differences between networks for exploration and exploitation, and concerning combinations and transitions between them.Arguments are presented that in some important respects go against the thesis of the strength of weak ties .Some empirical evidence is presented from recent studies.innovation;organizational learning;clusters;industrial districts;networks

Roadmap for Real World Internet applications

This paper emphasises the socioeconomic background required to design the Future Internet in order that its services will be accepted by its users and that the economic value latent in the technology is realised. It contains an innovative outlook on sensing aspects of the Future Internet and describes a scenario-based design approach that is feasible to roadmap the dynamic deployment of Real World Internet applications. A multifaceted socioeconomic assessment leads to recommendations for the technology deployment and key features of the Future Internet that will globally integrate technologies like Wireless Sensor and Actuator Networks and Networked Embedded Devices.Real World Internet ; Future Internet ; Scenario-based Design ; Socioeconomics ; Business Models ; Requirements
