New research has found that ALL students do worse in STEM classes where the professor has a fixed mindset, which means that professors believe that a student's intelligence is fixed and that there is little that can be done to improve academic success.  The bright side is that equity gaps were approximately 50% less in STEM classes where the professor had a growth mindset, which means that professors believe that the hard work and determination of the student can positively affect academic success.  Therefore, this research points to the fact that developing a growth mindset regarding our students is vital to their success.
