Without my former early adolescent students, this book would not have come about. I am indebted to them for fostering my interest in the early adolescent age group. They provided me with the inspiration and motivation (in more ways than one) to try to understand them and to find out what "makes them tick."
To the many researchers in the field of early adolescent development and education whose names are too numerous to mention, I am grateful. Much of this book is based on information they generated through decades of research.
For his assistance during the process of producing the book, I would like to extend my appreciation to my editor, Frank Darmstadt, and others on the staff at Insight Books (including my previous editor, Norma Fox) who made this book possible.
I would also like to express my personal and heartfelt gratitude to Dr. Conrad Toepfer for his careful review of the manuscript and for his valuable suggestions, guidance, wisdom, and inspiration.
For taking the time to thoughtfully review the manuscript, I extend my appreciation to Elizabeth MacDonald and Louise Warner.
