This research investigates rural area students' online adoption during the fourth wave of the coronavirus 2019 (COVID-19) pandemic. The main objective of this study was to identify the factors affecting the adoption of online education in rural areas in Sri Lanka. This case study was carried out based on data gathered from the online survey during the pandemic covering 16 districts in Sri Lanka. Using the ordered probit regression model through the stepwise technique, the study investigates the factors affecting the adoption of online education in rural areas in Sri Lanka. According to the results generated, attitude, perceived use, awareness, and new technology adoption have a positive impact on student adoption of online education in Sri Lanka. Online education so far is one of the effective and feasible solutions for providing education in a pandemic situation in any country. These findings are helpful for responsible educational institutions to address and contribute to key issues such as low perceived use, poor attitude, low awareness, and poor technology adoption. The study will also assist policymakers in preparing a roadmap, at the policy level with the perceived benefits of online education during similar future crises in Sri Lanka.
