Due to Covid-19 pandemic, the use of technology for delivering classes and content has become increasingly important. The presenter will discuss the effects of technology-supported flipped learning for English language classes at a Japanese national university. In the study, questionnaires were completed by 149 students in the writing course and 193 students in the speaking course. Data analysis combined quantitative and qualitative methods to reveal how the flipped approach with a learning management system (LMS) supported students’ speaking and writing skills in an online learning environment. The findings suggest that LMS is a practical platform that allows improved communication with students and extended opportunities for learning. Finally, the presenter will give suggestions for using LMS in future hybrid classes.
