I read this book as a part of my Master's courses for Educational Leadership and Administration.
This book is a pretty comprehensive collection of actions and steps for schools to take to improve student achievement. I really liked how it was organized into school, teacher, and student level factors. Marzano does a great job of synthesizing the research from several different sources. I appreciated that he wasn't too wordy with his chapters. I do wonder if anything was left out though.
One interesting note for me was his critique of how brain-based teaching may be over-stepping and changing more than it should. An interesting idea considering he critiqued the authors of the textbook for my other course. Let the debate ... continue.
