This study aims at highlighting the educational shift of the 21st century with the emergence of MALL as new language learning approach. Mobile-assisted Language Learning (MALL) is regarded as a newfangled approach of educational technology to teach and learn a language. Hundred students of different subjects and ten EFL teachers were the key participants for the study who took part in the questionnaire survey and discussion segment. The study has depicted the imperativeness of the use of mobile devices among both EFL students and teachers at the tertiary level of education in Bangladesh. As far as EFL is concerned, vocabulary knowledge is regarded as its vital part. Hence, the main focus of the study is to explore how EFL students exploit their mobile devices to acquire different skill of English language, and how EFL teachers use their mobile devices to teach them as well. Thus, the data were collected by means of students’ questionnaire and a focus group discussion (FGD) among ten teachers. The findings reveal positive attitudes towards the importance and use of mobile devices from both teachers and students. In addition, MALL is proved to be effective in enhancing EFL students’ vocabulary acquisition.
