Every teacher of mathematics constantly strives to teach well, to expect students to learn mathematics meaningfully, and to ensure that their classes contribute to their students' learning and growth.
However, it is not easy for many teachers who are conducting math classes to reflect on each lesson alone while conducting daily classes.
Moreover, the new era demands that mathematics classes and mathematics learning be changed, and students are growing up in different ways in different times.
This book is about the process of American teachers forming a community of teachers amidst these many concerns, collaboratively reflecting on mathematics classes, and the new challenges and attempts they made in the process and results.
This book is not very thick, but it is a large book that contains the sweat and effort of many members of NCTM.
Numerous studies and practices have been summarized and presented, and traces and examples of deep thought and discussion can be found throughout.
