Experience and Educationis the best concise statement on education ever published by John Dewey, the man acknowledged to be the pre-eminent educational theorist of the twentieth century. Written more than two decades after Democracy and Education(Dewey's most comprehensive statement of his position in educational philosophy), this book demonstrates how Dewey reformulated his ideas as a result of his intervening experience with the progressive schools and in the light of the criticisms his theories had received. Analysing both "traditional" and "progressive" education, Dr. Dewey here insists that neither the old nor the new education is adequate and that each is miseducative because neither of them applies the principles of a carefully developed philosophy of experience. Many pages of this volume illustrate Dr. Dewey's ideas for a philosophy of experience and its relation to education. He particularly urges that all teachers and educators looking for a new movement in education should think in terms of the deeped and larger issues of education rather than in terms of some divisive "ism" about education, even such an "ism" as "progressivism." His philosophy, here expressed in its most essential, most readable form, predicates an American educational system that respects all sources of experience, on that offers a true learning situation that is both historical and social, both orderly and dynamic.

Smart subjects for a Smart Nation? Governing (smart)mentalities in Singapore

It is well known that indoor wireless optical channels are limited not only in transmitted optical power, but also in signalling bandwidth. This bandwidth constraint arises due to multipath dispersion in indoor settings as well as due to response time limitations of optoelectronic components.

This paper presents an overview of theoretical and practical issues in the design of signalling for bandwidth constrained intensity modulated, direct detection wireless optical channels. A brief overview of the salient qualities of the wireless optical channel are presented to highlight the amplitude constraints which arise. A survey of modulation design is then presented which includes the review of a general technique to represent optical intensity modulation in a signal space and to construct optical intensity lattice codes. Results on the channel capacity of indoor wireless optical channels are surveyed and particular emphasis is placed on recently derived asymptotically exact bounds. The use of multiple emitters and receivers in wireless optical channels is also presented and particular emphasis is placed on techniques which exploit spatial dimensions to improve spectral performance. The paper concludes with some remarks regarding the status of the research area and suggestions for future work. Copyright © 2005 John Wiley & Sons, Ltd.

On the design of bandwidth efficient signalling for indoor wireless optical channels

Digital games can be powerful learning environments because they encourage active learning and participation within "affinity groups" Gee, 2004. However, the use of games in formal educational environments is not always successful O'Neil et al., 2005. There is a need to update existing theories of motivation and engagement in order to take recent game-related developments into account. Understanding the links between why people play games, what keeps them engaged in this process, and what they learn as a result could have a significant impact on how people value and use games for learning. This paper examines key research that relates to motivation, engagement, and informal learning through digital games, in order to highlight the need for empirical studies which examine the activities that occur in and around everyday gaming practice.

Scientific societies in the developing world must take a stake in their countries' future. They should be proactive in fostering a culture supportive of economic development driven by science and technology.

The opening of a virtual annex by science centers has given rise to a new genre of learning in Web-based education. Seeking to enhance the outreach effectiveness of nonformal science education initiatives among students and the public, these virtual science centers fulfill a useful role in promoting the public understanding of science. The example of the Singapore Science Center is used as a case study to explore the topic in significant depth. A commentary is also presented on some of the issues, controversies, and problems encountered in this new learning environment. Some possible solutions and recommendations are suggested in light of our experiences.
