This book reconceives the internationalization of higher education from the perspective of Global South researchers, empowering and giving visibility to this discourse. Challenging the first assumptions of internationalization of higher education (IHE) as something overwhelmingly positive due to the way it directly impacts the university activities and their world rankings, it instead takes a critical perspective, acknowledging that this process is associated with a neoliberal and colonial orientation that focuses on the maintenance of historically sustained hierarchy, oppressive relations that stimulate the production of knowledge, and education as a commodity and not as a factor of social transformation. As such, it challenges recent trends toward an increase in internationalization strategies within higher education that privilege Global North outgoing mobilities and research collaborations to sustain the position of the educational institutions in the international rankings. From this locus, IHE is seen not only to evolve in the fields of teaching, research, and service of an educational institution but also to boost the world’s social development. The book thus illustrates how IHE should be guided by Critical Applied Linguistics (CAL) and Global South’s principles: applied linguistics, praxis, critical thinking, micro and macro relations, critical social inquiry, critical theory, problematizing givens, self-reflexivity, preferred futures, and heterosis. Comprising chapters that discuss academic, political, and administrative issues arising specifically from the internationalization process of Global South higher education institutions, as well as themes such as critical language education and language policies, it will appeal to faculty, researchers, and scholars with interests in higher education, international and comparative education, and the decolonization of education.
