This document summarizes the work of Rajiv Jhangiani, an open education advocate. It discusses how education can serve as a form of activism and social justice by increasing access through open practices. It notes how traditional higher education systems often reinforce existing power structures and presents barriers like high textbook costs. Open educational resources (OER) like open textbooks can help reduce costs and increase access and flexibility. Research shows students using OER have lower withdrawal rates, higher pass rates, and take more courses. The document advocates increasing open practices and OER adoption to advance pedagogical innovation and make education more equitable and accessible.
