I work for a large industrial company as a business analyst but have moonlighted for the last 10 years as a math tutor for junior and senior high school students. While I don't stand in front of a class 6 periods a day, the principles of effective teaching and many of the specific techniques described in this book will be helpful to me. One-on-one tutoring can include game playing, creating (virtual) products, open inquiry, even competition. I can see how "best lesson" methods from other academic areas can be applied to math but also like the book's index of examples by subject.My primary appreciation for the book is its promotion of teaching in the classroom in a manner similar to how learning occurs in the business world. From my work experience, new products get developed, hard problems get solved through a parallel combination of 3-dimensional relationships, creativity, multi-modal modeling, and collaboration as described in the Reichert, Hawley book. Full-time teachers who pick up a few new lesson plan ideas from this book can, hopefully, give their students skills to continue learning after the last school bell rings.
