The authors ground their work in research, documented at the conclusion noting the field work and fidelity to their accuracy ambition.
The first fifty pages or so I wasn't yet sold. Chapter four was the hook that got me- how do you answer the three questions as a teacher- what kind of teacher are you and what you stand for. The book is well written, and not as easy to read as some due to the intensity of their work. Page after page as I continued, I pondered what balance I aim for with children, am I happy with the relationships I have with colleagues and families, and do I transmit or transform societal values. It's not a superficial glaze, but thought-provoking material written almost twenty years ago noting aims and anticipated changes for the year 2020.
I'd definitely buy and read the book- or at least borrow one from a library. It's worth every minute.
