Advances in technology have significantly augmented the potential of online education, particularly during crises, such as COVID-19, earthquakes, hurricanes, and floods. This qualitative survey study ascertains 150 English-as-a-foreign language (EFL) learners' perceptions of the efficacy of online language education in a preparatory school of a state university after the Kahramanmaraş earthquake in Türkiye in 2023. Data were gathered via an online survey with open-ended inquiries to elicit favourable and adverse experiences and recommendations from students. In order to ensure the thorough and systematic analysis of the collected data, a rigorous methodological approach was employed. Specifically, the data were analyzed through content analysis, facilitated by the MAXQDA. The research outcomes revealed that the participants appreciated online language education for its time-saving nature, comfort, ease of attendance, access to recorded sessions, teacher support, and cost-effectiveness. However, some students also considered online education ineffective and reported challenges, such as technical issues, diminished concentration, lack of motivation and discipline, limited interaction, and class participation. EFL learners also provided suggestions for improving the curriculum, assessment methods, and instructors’ teaching approaches.
