Academic mobility and cultural diversity have continuously increased in higher education in recent years. Consequently, the language barrier has become an important issue in the learning process, mainly in Europe where there are 24 official languages. In animal and veterinary sciences, the complexity of vocabulary used during the learning process exacerbates this problem. To overcome this problem, lecturers must create an interactive and engaging classroom atmosphere, provide a reduced and concise lecture and promote interaction between students through the promotion of discussion. The use of e-tools also contributes to student interaction. When teaching animal biological processes, hands-on laboratory exercises and case-based activities also help overcome language barriers between students and lecturers. Lecturers need to create an interactive classroom through the use of direct and concise language and new technologies to promote learning in international classrooms.
