Rather than advocating a specific method, Powerful Professional Development: Building Expertise Within the Four Walls of Your School presents a full toolbox of professional development strategies with suggestions for implementation and recommendations about which tools to use at different times and in different contexts. Using this comprehensive resource, schools can move away from the traditional model of professional development that relies on outside experts, and instead draw on and develop the skills and talents of their own faculty.

Covering a range of approaches and techniques and sharing examples of lessons learned from schools and districts that have cultivated these approaches successfully, the authors describe and evaluate a full spectrum of models of job-embedded PD, including

- Book study

- Webinars

- Co-teaching

- Open space technology

- Lesson study

- Action research

- Coaching

- Professional learning communities

- Online communities, and more.
