This study uses a critical perspective to examine how online education is used in brick-and-mortar institutions as a mechanism through which power is exercised by and against professors who teach online. Based on a larger study of 25 professors and administrators at four institutions, this work focuses on the experiences of 12 professors. Foucault's conceptualization of power framed our interpretation of interviews conducted with these professors. Our findings suggest online education enhanced faculty autonomy and visibility, but that it was also used to control faculty members, and for some professors, it was used to alter their professional identities.
