Sara Goldrick-Rab, a professor of higher education and sociology at Temple University in Philadelphia, has built a large Twitter following in part through frank exchanges about her research on higher ed. policy and and college access for low-income students. She also landed in hot water after tweeting that Republican Gov. Scott Walker of Wisconsin is a “fascist” and comparing him to Hitler. At AERA 2016, Goldrick-Rab talked with Education Week about the role of social media in academic life and work.
