Previous studies have showed the effects of different methods used in teaching the speaking skill in language classrooms in Vietnam. Yet not many language practitioners have focused on activities and techniques to improve EFL learners’ speaking fluency. This study looks at the use of the 4/3/2 technique in speaking classes. Data were collected through an experiment among first year English majors who were following the usual English program at a university. It was found that the treatment group outperformed the control group in terms of speaking fluency and accuracy. The study highlighted the benefits of the 4/3/2 technique and suggested that fluency and accuracy in language performance do not have to be in a trade-off relationship.
