I'm wrestling with something today, y'all: I was working with some teachers who gave me the "our kids couldn't do that because they are too low" line of thinking.
Given that teacher estimates of student achievement is the practice with the greatest potential to accelerate student learning in Hattie's research, that kind of thinking riles me up.
How do you respond when your peers doubt their students? Is that something you ignore? Tolerate? Address?
I am not sure, but teachers really do need to believe that their students can achieve to the best they can be.
Low self esteem can be one factor, brought on by others not thinking they can do' we have failed before we even try sort of thing.
Maybe with this group have a look at

but also find out what they think is holding them back, what ARE they good at, what ARE they not so good at, reflecting on the positive at least means you are not thinking I am never going to get anywhere.
Not sure if this helps,
Paul
