Résumé:
The main aim of this research is to investigate the challenges faced by learners and teachers in teaching and learning English for Specific Purposes (ESP) vocabulary. The study seeks to identify the underlying causes of these difficulties and propose effective solutions to overcome them. The hypothesis guiding this study posits that by recognizing and resolving the challenges faced in the instruction and acquisition of ESP vocabulary, it is possible to enhance the overall teaching and learning processes. The research methodology employed in this study utilizes a quantitative research approach, utilizing two questionnaires designed for both teachers and students. The students’ questionnaire was submitted to 86 out of 193 third-year students at the department of Commercial Sciences at the University of Mohamed Seddik Ben Yahia-Jijel. It aims at gaining an understanding of the challenges students face in learning ESP vocabulary whereas the second questionnaire was submitted to 4 ESP teachers who teach at the same department. It aims at gathering information regarding the difficulties these teachers face when teaching ESP vocabulary and to gain insight into their perspectives on the students' challenges in learning ESP vocabulary. The results show that if teaching and learning ESP vocabulary challenges are identified, the teaching and learning processes could be improved. Based on the findings of this research, some pedagogical recommendations were suggested to help both learners and ESP teachers overcome their challenges.
