The article contrasts General English courses with English for Specific Purposes (ESP) courses, highlighting that ESP courses are tailored to the specific needs of learners in a particular field or profession. ESP courses are more learner-centered and take into account the learners' goals and purposes for learning English. The article provides an overview of ESP courses, including their objectives, characteristics, and instructional strategies, such as developing needs assessments, adapting authentic materials, and using technology-based evaluation methods. Three common features of ESP courses are the use of authentic learning materials, purpose-related orientation, and self-direction. Additionally, ESP courses prioritize self-directed learning and teach learners how to learn by teaching them about learning strategies. Finally, the article emphasizes the importance of tailoring ESP courses to high-ability learners, such as those in health science programs, by teaching them how to access information in a new culture.
