The COVID-19 pandemic has changed the way of learning in higher education institutions (HEIs). Most HEIs shifted the way of learning from traditional learning to online learning. However, the crisis had raised a critical question regarding the impact of the digital divide on students learning. Access to technology such as computers, the Internet, and having enough digital skills become more important than ever to ensure that all students have equal learning opportunities. This dissertation aimed to investigate students' online learning experiences, the impact of the digital divide on their access to online courses, and the challenges and obstacles students faced during the COVID-19 pandemic in the College of Education at a public university in southwest the Kingdom of Saudi Arabia (KSA). The qualitative case study method was used for this dissertation. Data was collected through semi-structured online interviews with 12 undergraduate and graduate students from the College of Education at a public university in the southwest the KSA. Findings revealed that participants showed positive online learning experiences because of the advantages of online learning, such as flexibility and convenience. On the other hand, participants also shared negative experiences due to the challenges and obstacles that negatively impacted their online learning experiences, such as the lack of interaction, inappropriate online courses design, online teaching methods, time management, psychological and social symptoms, and accessibility issues. The findings could help instructional designers, instructors, and higher education administrations understand students' online learning experiences during COVID-19 and help promote and improve students' online learning experiences.
