Because Teaching Matters provides teachers with a realistic depiction of today s classrooms while highlighting the enormous impact they have on everyday lives. The second edition presents material around a framework of five professional commitments that allows them to make sense of what it means to be a teacher. A new critical-thinking framework helps them manage the content better and retain more of what they learn. Increased coverage of diversity and technology is integrated throughout the chapters. A new chapter has also been added on the history and philosophy of education. This book will help teachers make decisions and take responsibility for the consequences of those choices.
