I guess I hit my "quit point" with this book 🤣 . No, I actually think the book is written well-enough and it seemed the research involved was pretty fair (been a long time since I last cracked its spine), but it's hard to maintain reading these annual summer books into a busy school year, especially when the books are not followed up on by the admin team or staff. 🤷♂️
As best I recall, the thesis seems to be that each student has their own factors having nothing to do with school or your classroom that bear on their ability and desire to persist with stretching academic work, and the key for the teacher is to identify those factors and where that student's quit points might be, and somehow coax them beyond those quit points to get intellectually growing.
