This is a helpful book with a lot of practical applications and tips, not just theory. A lot of the practices are simply just good teaching practices (e.g. don't cold call), and it makes complete sense that practicing good pedagogy is good for students mental health.
I was disappointed to see a lengthy discussion on building grit and growth mindset -- if you also side eye those concepts, just know this book will not examine critiques of them. There was also a suggestion in the wellness chapter about a nutrition class assigning students to eat nutritiously every week, which from an eating disorder recovery standpoint was pretty surprising to see here in a book on improving mental health.
