I like this little book, and I like how it's organized into five sections: self-talk, teacher to student communication, peer to peer communication, school to home communication, and whole-school mindset. I have always said that our inner monologue can be helpful or harmful based on what we tell ourselves again and again; the lesson in this book certainly support this idea.
I know that growth mindset is the new buzz phrase (well, new for the last three years or so), but this book provides concrete suggestions, activities, and ideas to use with students, colleagues, and family to promote growth mindset. I completely connected to the art example (the last reference in the book). I expect a few of the examples in this book will anger some, particularly those about copying homework, failing tests, and not following rules, but I hope we consider the suggestions (even if we choose not to follow them) in order to examine how we teach and interact (is it more punitive than focused on learning?).
I think all teachers in my school should take the silo quiz on page 130 and then have discussions about the entire chapter on peer to peer communication!
