Masks pose a unique challenge in the EFL classroom, as attenuated speech signals, loss of visual cues, and even discomfort can have a negative impact on the L2 learner. This study investigated the effects of masks in the EFL classroom through questionnaires and listening comprehension tests with particular interest in the role of teachers’ L1, visual cues, and microphones. An overview of the research and results with an emphasis on recommended practices will be presented.
