8 Ways to Boost Students Engagement During Asynchronous English Language Learning by Nurkarimah, Yusof

“…For some students, asynchronous learning is the ultimate game-changer, as it offers flexibilities and new learning opportunities such as self-paced learning. On the other hand, some students may face challenges, particularly in maintaining their motivation and self-discipline to learn, for example in language courses such as English, without direct face-to-face interactions during this learning mode.…”
