Abstract
Integrating translation in English for specific purposes (ESP) teaching and learning is a crucial issue since the last decade of the 20th century. This paper aims to analyse the role of translation as a helpful tool for ESP classes on the use of translation in ESP teaching and learning. Therefore, a case study is employed to describe the necessity of using translation in ESP classes, especially, for third-year computer science students at the University of Tlemcen. A mixed method was used; a questionnaire was administered to ESP teachers in the Department of Science and Technology, and classroom observation on third-year students of computer science was conducted. The results revealed that computer sciences students at the University of Tlemcen faced various hindrances when dealing with professional resources which are mainly at the level of content due to the nature of ESP courses they were exposed to during their studies. Keywords: Computer science; ESP; ESP courses; students; translation.
