However, many lecturers/teachers and students in Vietnam have not been familiar with this teaching/learning mode yet. Training lecturers/teachers to use the elearning system at a school or university is an important issue in terms of effective teaching/learning and school management. Few research studies have been investigated to study the useful model of e-learning classrooms during this critical time. This paper presents an overlook of e-learning issues around Asia during the Corona Virus pandemic.
