This document summarizes a study that investigated the motivation and attitudes towards learning English of 81 petroleum engineering undergraduates at Hadhramout University of Sciences and Technology in Yemen. The study found that students were primarily instrumentally motivated, motivated by practical reasons like career goals. Students were less integratively motivated, motivated by a desire to integrate into English cultures. Students also had positive attitudes towards the social and educational roles of English in Yemen. The study provides insights that can help improve English language teaching for these students.
