The COVID-19 global pandemic has resulted in many countries moving teaching and learning online. South Africa is a country with major inequalities in terms of access to electricity, internet and information technologies, which have created considerable problems for online learning at institutions of higher learning in the country. In this paper, we analyse student feedback from two large undergraduate English courses at a school of Education of a major South African university. We specifically focus on two qualitative questions which asked students about the challenges they faced and the skills they developed in online learning. Results are considered through the lens of critical digital pedagogies and decolonisation. Our findings indicate that a lack of access and resources, disruptive home environments and unfamiliarity with online learning methods were significant obstacles for students. In addition, many students indicated developing computer skills and learning how to use online resources during the courses. The study suggests that online teaching and learning in South Africa and similar contexts exacerbates inequalities, and must be accompanied by rigorous support structures for students who are vulnerable in these contexts.
