The proliferation of massive open online courses (MOOCs) has stirred a fervent debate about global access to higher education. While some commentators praise MOOCs for expanding educational opportunities in a more open and accessible fashion, others criticize this trend as a threat to current models of higher education and a low-quality substitute for traditional learning. Drawing on a comprehensive literature review of both academic and popular media sources, this article will explore the impact of MOOCs on the field of higher education, with a particular emphasis on their promise to enhance educational opportunities worldwide. Specifically, the analysis will focus on the four issues that have--so far--proven to be most significant in shaping the future of MOOC as an equalizing force in higher education: credit, pedagogy, internationalization, and, finally, legal and financial aspects.
