Catalyzing change was a very interesting read and contains a great deal of useful information for me as a high school math teacher. Some of the biggest issues current math teachers must face in their everyday classroom are addressed and focused upon in this book. Such us driving how math is introduced to students, overcoming generational views of negativity toward math, identifying concepts all students in high school math should learn to be successful, and ways to help students improve and grow their mathematical understanding and identity. And those are just a few of the issues that are focused on. As math teacher was must find ways to overcome students everyday views on mathematics and obstacles that impede every students ability to understand it. This book also provides examples for how teacher can use all the information provided to them and ways they can incorporate it into the classroom. This book shows us that as math teacher we need to make math class go beyond just college and career readiness. Math class needs to incorporate many aspects of life, for example the news, such as using the graphs and other mathematical representation that is being used in it. Overall for any math teacher that wants to help grow their students and truly show them how far math can take them this book is a good read.
