Résumé:
Vocabulary learning is an essential task in foreign language learning. Consequently, instructors and educators start to use new methods of teaching such as the use of technologies in the EFL classrooms. The present research aims to investigate the effectiveness of YouTube videos in enhancing EFL learners’ vocabulary, mainlyforsecond year students at the DepartmentofEnglish at Larbi Tebessi University. It seeks to highlight the importance of using YouTube in the classroom environment as a tool for teaching English as a foreign language and for vocabulary mastery. The study hypothesizes that EFL learners who watch YouTube videos are more likely to learn and master vocabulary than thosewho are not exposed to YouTube videos for learning. To test this hypothesis andotherassumptions, we have conducted a descriptive study that focuses on both qualitative and quantitative methods. Also, we have used the convergent parallel design. We have administered a questionnaire to 105 students of secondyear and an interview to 13 teachers asdatacollectiontools. The interview and the questionnaire were conducted to investigate the attitude of the teachers and the learners towards the role of YouTube in enhancing EFL learner’s vocabulary. The study results show the positive role of using YouTube videos to enhance EFL student’s vocabulary as it is advantageous in facilitating language learning and teaching. Also, the findings show that both of the teachers and students have supported the use of YouTube.
