Sommario/riassunto

This book provides clear guidance for K-12 teachers in giving students globally connected literacy experiences. With the help of readily available technology tools, educators can create environments where students gain 21st century skills, know their work matters, and see their work travel beyond classroom walls. Readers will: examine key features of authentic global collaborative experiences and the benefits of a globally connected classroom; gain tips for creating authentic and successful global collaborative projects; discover what steps they can take immediately to foster global literacy in their classrooms; answer reflection questions to contemplate how they can apply the ideas and strategies in this book to their own classrooms.

Sommario/riassunto

Superconductivity is a quantum phenomenon that manifests itself in materials showing zero electrical resistance below a characteristic temperature resulting in the potential for an electric current to run continually through such a material without the need for a power source. Such materials are used extensively in medical and power applications, e.g. MRI and NMR machines.   Discovering Superconductivity uses a series of practical and investigative activities, which can be used as tutor demonst
