In today’s globalized world, engineering education must prepare students to navigate multilingualand multicultural contexts effectively. While traditional engineering curricula emphasize technicalexpertise, there is growing recognition of the need to integrate essential skills like multilingualisminto higher education. Multilingual competence enhances students’ ability to communicate,collaborate, and solve problems in diverse professional settings, making it an invaluable asset forfuture engineers. To address this need, we have designed a plurilingual course for engineeringstudents at the Royal Institute of Technology (KTH) in Stockholm, Sweden. The course builds onstudents’ existing language skills and develops additional linguistic competencies relevant toprofessional contexts. With a focus on real-world applications, it employs a plurilingual approachfocusing on intercomprehension, code-switching, cross-cultural communication and mediation. Wewant to explore the role of plurilingualism in engineering education by addressing the followingresearch questions: (1) How does a plurilingual approach enhance engineering students'communication and problem-solving skills? (2) How do students perceive the value of multilingualcompetencies in their academic and professional development? (3) How can plurilingual educationbe effectively incorporated into technical university curricula? To investigate those questions, we willpresent an initial evaluation of the course (first run during spring 2025), based on qualitative datacollected through student interviews and feedback, providing insights into the course’s impact onboth students and instructors. In addition, we will examine how students recognize and valueplurilingualism in their education and future careers. We will also discuss how such a course fits intothe language unit of a technical university and how it can be used for future course development. Byembedding plurilingual education into engineering studies, we aim to set a new standard forintegrating essential skills into STEM education.
