This study investigated the motivation and attitudes of 81 male petroleum engineering undergraduates toward learning English at Hadhramout University of Sciences and Technology in Yemen. The results found that instrumental motivation, such as using English for career purposes, received the highest scores and was the primary motivation. Students had positive attitudes toward using English in Yemeni social and educational contexts but negative attitudes toward English-speaking cultures. The researchers concluded that instrumental motivation was the main driver and integration motivation had the least impact on students' English learning. However, the study was limited by only including male students. Future studies could use standardized tests and interviews with workplace English students to further understand motivation and attitudes.
