Teaching and learning of English as a foreign language is not only challenging, but using English as medium of instruction is also crucial. When it comes to the places where English in not a lingua franca (a link language), the challenges simply double and both the teachers and learners face many problems due to the fact that the target subject (biology) is difficult and the medium of teaching (English) is also not easy. Teaching of English as a subject as well as a medium of instruction (teaching) in the Gulf region in general and Saudi Arabia in particular catches attention of many researchers and scholars especially when the issue is particularly related to poor achievement. Teaching of English at preparatory level (foundation year) at King Abdulaziz University (KAU), Jeddah serves two purposes: first, it lays and strengthens the foundation of general English that they carried forward from schooling. Second, the learners are made proficient in English during the foundation year so that they can pursue their specialties later. Despite the fact that English in Saudi Arabia is generally taught at school levels also, the achievement is far below the expectations from the viewpoint of English teachers at Biological/medical/health related subjects. Moreover, ‘Englishes’ at these departments are known as specific, and teaching/learning is somewhat different from the context of general English. Therefore, the present article is intended to explore the teachers’ perception and factors contributing to the difficulties in learning general as well as specific English. In addition, it focuses on sort of remedial teaching required to prepare the students at biology department. Article visualizations
