This short story reflects on my teaching days before and during the COVID-19 pandemic. One day, I asked my students to write a reflection about the course, Language and Culture, which made me ponder my teaching. I decided to try out flipped learning pedagogy with my class at a university in South Korea. Based on my results, as both an instructor and a researcher, I would like to strongly suggest that flipped learning classrooms and activities should systematically apply best practices for successful active learning in online and offline contexts.
