If mindsets impact students, what about faculty mindsets?
If, for example, faculty believe specific students lack the necessary ability do they treat them differently? Do they give up on them more quickly? You may want to check out an article titled "It's ok - Not everyone can be good at math" (Rattan, Good, & Dweck, 2012). See References.
Are faculty unwilling to change because they have fixed mindsets about their own abilities? Check out this link for an article on the topic.
