Book excerpt: This book discusses learning and teaching with modern technology in the new knowledge society. It focuses specifically on new literacy and technology in classroom environments. Based on a social-constructivist approach, this book covers a wide range of new technology use examples, such as participatory media, video recording systems and 3D computer graphics. A case study on a constructivist approach to teaching and learning, especially CSCL (computer supported collaborative learning), is discussed from a practical perspective for educators. It also includes specific in-class practices with detailed accounts of curricula featuring readily accessible yet new technology available for classroom use, such as Google Sketchup 3D computer models.
