The COVID-19 has required a rapid conversion from the conventional learning to online learning, revealing and intensifying the digital inequality amongst university pupils. The primary objectives of this systematic review study are to identify the digital divide challenges encountered by university students in online learning amidst the COVID-19 pandemic and to understand the underlying reasons contributing to these challenges. This study focuses on empirical research published between 2020 and 2023. The review utilized the seven phases of systematic review recommended by the Evidence for Policy and Practice Information and Co-ordinating Centre. A comprehensive Scopus and Web of Science search was undertaken using word string "higher education/university education/university students", "online learning/distance learning," "COVID-19/pandemic,” “digital divide/digital inequality/digital exclusion," and, and the initially 190 articles were extracted.The criteria for inclusion restricted the number of publications that were examined to a total of 11. The analysis reveals two primary categories of digital divide challenges: the first-level digital divide, characterized by limited access to essential digital devices and internet connectivity, and the second-level digital divide, which relates to varying levels of digital competency among students.Key factors contributing to these challenges include financial constraints, geographical disparities, and inadequate technological infrastructure. Students from economically disadvantaged backgrounds and rural areas faced significant obstacles in engaging with online learning platforms, leading to adverse academic outcomes. Strategies for bridging the digital divide should be implemented in collaboration with educational institutions, government agencies, and private sector stakeholders. These strategies should focus on the enhancement of technological infrastructure, the provision of financial support, and the provision of digital literacy training programs. The review highlights the importance of understanding the digital divide in shaping future educational practices and policies, aiming to create a more inclusive and resilient higher education system in the post-pandemic era. By addressing the identified challenges, institutions can empower all students to succeed in an increasingly digital learning environment.
