ABSTRACT
Good theories can be tools for understanding reality as it is presented to us and prevails for us. Theories are ways of trying to control chaotic, unpredictable, and ambiguous reality. Theories are applied with a view-in-mind of interpreting the context in which they are developed. They try to respond to the challenges that produced them. They also try to address the purposes for which they are developed and try to provide answers to the problems they are intended to resolve. A good theory should put into order the existing knowledge in a particular area to the extent that the summary can become a logical model or even a working system for predicting future events. I opened this book by proclaiming that the story of teacher development started with economics. In many ways it began and continues with economics even to the present day.
