Technology  development  has  brought  many  changes  to  the  methods  and techniques  of  teaching  and  learning  English  in  Vietnam.  Online  drama,  or “Digital Theatre” is a new teaching technique that was formed and developed based on the traditional drama techniques in the classroom with the support of  technology.  The  study  was  conducted  to  compare  the  perceptions  of teachers who have and who have not applied the above technique to teaching and learning English in Vietnam. From the survey results, in many respects, the group of teachers who have applied “Digital Theatre” to teaching found that the impact of this technique was greater than what the “have not applied” group  perceived.  The  research  results  highlight  the  potential  of  “Digital Theatre” in teaching English in Vietnam. Simultaneously, the current study also encourages teachers to apply this technique in their teaching because its impact on learners’ performance has been verified with authentic experience.
