For fulfilling the purpose of this study, a quasi-experimental research was conducted to urban management students at the university of Larbi Ben M'Hidi in Oum-El-Bouaghi. Participants who were students taking ESP courses were assigned to two groups of 15, a control and an experimental group. The experimental group was taught on the basis of the task-based approach, whereas the control group was taught using the traditional method. After the treatment period, a post-test was administered to the groups, to determine the influence of the treatment on the experimental group. The results indicated that, task-based approach was more effective in teaching vocabularies compared to the traditional approach used before the implementation of TBA. Therefore, the present study suggests that Task-based approach is efficient in improving vocabulary learning in ESP courses.enTask-based : language learning : teachingVocabulaire : apprentissage : lectureOther
