This document provides an overview and rationale for the book "Teaching to Learn, Learning to Teach: A Handbook for Secondary School Teachers." The book is intended to help preservice and new teachers by integrating practical, theoretical, and critical perspectives on teaching. It draws on the work of educational philosophers like Dewey, Freire, and Ladson-Billings. The book addresses broad topics in secondary education rather than specific subjects. It presents a model of student-centered "PRO/CLASS Practices" and includes examples and reflections from teachers. The goal is to help new teachers develop their own reflective approach to building effective classrooms and becoming the kind of teacher they want to be.
