This study examines the attitudes of teachers and students towards the implementation of content and language integrated learning (CLIL) in the interdisciplinary study program English in Electrical Engineering and Informatics at Brno University of Technology (BUT). It aims to explore the benefits, challenges, and strategies for CLIL in the linguistics and engineering study program. Two questionnaires were administered to 39 students and 15 technical subject teachers, focusing on their language levels, preferences, and experiences in learning and teaching technical subjects in English. Research results revealed positive perceptions among both groups regarding the development of language skills and subject knowledge, underscoring the importance of English as a lingua franca (ELF) in science and technology, enabling professionals from diverse linguistic backgrounds to collaborate and share findings effectively. Students highlighted the need for flexible instructional approaches to accommodate diverse learning preferences, and teachers emphasized the necessity of meticulous planning and consistent practice. Challenges identified included language barriers for both students and teachers, which can impede effective learning and teaching. The study draws attention to the need for heightened awareness of ELF of science and technology, recommending refined instructional approaches and enhanced support mechanisms to overcome language challenges and optimize CLIL implementation in engineering education.
