Résumé:
Learning Vocabulary is a very important skill in the process of learning a language, especially
for EFL learners who want to improve their skills to use English effectively while
communicating; however many EFL students at the University of Guelma face some
difficulties that prevent them from using the target language appropriately due to their lack of
vocabulary. This research explores EFL learners' attitudes toward learning new vocabulary
using the Duolingo Application. The core hypothesis of this research assumes that EFL
learners ' vocabulary would develop if they use Duolingo. In order to test the aforementioned
hypothesis, a descriptive quantitative method is used, in which a questionnaire is designed and
distributed to Sixty second-year students (L2) who have already used Duolingo, at the
Department of English, University of 08 Mai 1945 - Guelma. The analysis of the collected
data corroborates the hypothesis; these findings underscore that most EFL Learners have
positive attitudes towards the Duolingo Application in enhancing their vocabulary. The results
also revealed the effectiveness of the Duolingo app. in enhancing EFL learners’ vocabulary.
Thus, our research hypothesis is confirmed. So it is better recommended for EFL Learners to
use the Duolingo Application as a tool for their vocabulary development.
