"Christine M. Rubie-Davies is an internationally recognized scholar in the area of research on teacher expectations and classroom climate and student learning. In this book, she explains why teachers’ performance expectations are important, how they are communicated, and how they can be enhanced in ways to improve student learning. She translates this complex research topic and lucidly conveys the important, central messages embedded in hundreds of studies. This book is fundamentally important for those who plan to teach or those who conduct research on teaching."—Thomas L. Good, Professor Emeritus of Educational Psychology at the University of Arizona, USA
