A recent article by Seth Gershenson and Thomas S. Dee was about the impact of unconscious racial and gender bias in K-12 classrooms.  The article cites research that clearly shows how this bias hurts minority and female students and, that it is very difficult to effectively counter this bias. To reduce this insidious threat, parents of school-age children must be involved with the schools and specifically their children’s classroom environments. This is even more important today as public schools become more segregated.
