Book excerpt: We are living in a defining moment, when the world in which teachers do their work is changing profoundly. In his latest book, Hargreaves proposes that we have a one-time chance to reshape the future of teaching and schooling and that we should seize this historic opportunity. Hargreaves sets out what it means to teach in the new knowledge society, to prepare young people for a world of creativity and flexibility and to protect them against the threats of mounting insecurity. He provides inspiring examples of schools that operate as creative and caring learning communities and shows how years of "soulless standardization" have seriously undermined similar attempts made by many non-affluent schools. Hargreaves takes us beyond the dead-ends of standardization and divisiveness to a future in which all teaching can be a high-skill, creative, life-shaping mission because "the knowledge society requires nothing less." This major commentary on the state of today's teaching profession in a knowledge-driven world is theoretically original and strategically powerful?a practical, inspiring, and challenging guide to rethinking the work of teaching.
