Visible and Invisible
Light phenomena have intrigued humankind since prehistory. Think of the rainbow, a sunset on the sea, a game of shadows. Humans have always used light for their own needs, from cooking food to illuminating a room. However, light is not only limited to what we can see with our eyes. The invisible part of the electromagnetic spectrum is broad and dynamic. This book outlines the mysteries and wonders of electromagnetism, heat, and light. It also covers the history of our scientific understanding of light. The dark as well as the bright sides of light are fully explored in these pages, from their impact on our world to their use in cutting-edge technologies in a variety of fields. Numerous full-color images and drawings complement the text, and light phenomena are explained in a simple and engaging way.
Art and Creativity in Reggio Emilia
This book explores the contribution of and art and creativity to early education, and examines the role of the atelier (an arts workshop in a school) and atelierista (an educator with an arts background) in the pioneering pre-schools of Reggio Emilia. It does so through the unique experience of Vea Vecchi, one of the first atelieristas to be appointed in Reggio Emilia in 1970. Part memoir, part conversation and part reflection, the book provides a unique insider perspective on the pedagogical work of this extraordinary local project, which continues to be a source of inspiration to early childhood practitioners and policy makers worldwide. Vea’s writing, full of beautiful examples, draws t...
Activity Theory in Formal and Informal Science Education
The purpose of this book is to establish a broader context for rethinking science learning and teaching by using cultural historical activity theoretic approach. Activity theory already steps in its third generation and only a few works have been done on its applications to science education, especially in Europe. The context takes into account more recent developments in activity theory applications in US, Canada, Australia and Europe. The chapters articulate new ways of thinking about learning and teaching science i.e., new theoretical perspectives and some case studies of teaching important scientific topics in/for compulsory education. The ultimate purpose of each chapter and the collect...
Silicon-based Microphotonics: from Basics to Applications
The evolution of Si-based optoelectronics has been extremely fast in the last few years and it is predicted that this growth will still continue in the near future. The aim of the volume is to present different Si-based luminescing materials as porous silicon, rare-earth doped silicon, Si nanocrystals, silicides, Si-based multilayers and silicon-germanium alloy or superlattice structures. The different devices needed for an all-Si-based optoelectronics are treated, ranging from light sources to waveguides, from amplifiers and modulators to detectors. Both the very basic treatments as well as applications to real prototype devices and integration in an optical integrated circuit are presented. Several issues are highlighted: the problem of electrical transport in low-dimensional Si systems, the possibility of gain in Si-based systems, the low modulation speed of Si-based LEDs. The book gives a fascinating picture of the state-of-the-art in Si microphotonics and a perspective on what one can expect in the near future.
Arte y creatividad en Reggio Emilia
Este libro explora la contribución de las artes y de la creatividad en Educación Infantil. También estudia el papel de los talleres de artes y del profesorado de educación artística en las escuelas de Educación Infantil de Reggio Emilia. Lo hace a través de la experiencia de Vea Vecchi una de las primeras especialistas de educación artística en Reggio Emilia. Esta obra construida como memoria, conversación y reflexión proporciona una perspectiva única del trabajo pedagógico de este proyecto que sigue siendo una fuente de inspiración para todo el profesorado de Educación Infantil así como para quienes planifican las políticas educativas en cualquier parte del mundo. El texto ...
