In recent years, job candidates are currently required not only professional knowledge and skills but also English specifically implemented in particular occupations. Since then English for specific purposes (ESP) is the latest trend which has exponentially developed. The majority of universities have deployed diverse ESP courses in order to help learners address communicative needs as well as practices of particular professions. Ho Chi Minh City University of Transport has also provided interesting ESP courses supposed to assist engineering and technology students in their future careers. Not only inspired by the need to enable the learners of these courses to increase their knowledge of terminology in their fields but also integrating technology in language teaching and learning, this paper aims to suggest Quizlet a mobile and web-based study application as a tool to facilitate specialized vocabulary acquisition for learners of English for engineering and technology as well as for those who are learners of English for specific purposes in general. Thanks to Quizlet, both teachers and students will take full advantages from this innovative method that is probably proliferating their new learning and teaching experiences. Although the merits outweigh in this sphere, it is obvious that Quizlet should not be compulsory, but combined with other strategies to eventually give fruitful assistance to meet learners’ increasing demands on the verge of the industrial revolution 4.0.
