Drawing on stereotype threat and social identity threat research, this talk will address the why, what and how of diverse learning communities: why they are important, a working hypothesis about what is critical to their success and what research reveals about how to achieve that success. The talk’s practical aim is to identify features of diverse learning communities—schools, universities and academic disciplines—that while good for all students, are especially helpful for minority students generally, and for women in STEM fields. The talk will also explore the psychological significance of community and its role in learning.
