This study investigates the effects of the switch to online instruction in higher education in Sri Lanka after the COVID-19 outbreak. The study examines different aspects of the move to online education using a mixed-methods methodology that combines quantitative analysis of student satisfaction surveys and qualitative analysis of educator interviews. Qualitative study highlights the difficulties educators have in adjusting to digital platforms, the methods they use to improve student learning outcomes, and the advantages and disadvantages they see in online learning. A quantitative analysis looks at how satisfied students are with their online learning experiences and identifies the main variables that affect their engagement and academic success. For online education to be as effective as possible, the results highlight the necessity of continuous professional development for teachers, fair access to technology for students, and creative pedagogical strategies. In the context of post-pandemic higher education in Sri Lanka, the study adds to the body of literature by providing insights into the intricate interactions among technology, pedagogy, and social behaviors. Future study should focus on comparative evaluations of various online learning platforms, long-term studies to evaluate the effects of online learning, and examinations of challenges related to inclusion and digital equity.
