This paper presents the results of a series of subject and language-training tandem projects aimed at teaching adult learners how to respond to emergency situations in Estonian and Russian. The purpose of this paper is to discuss the effectiveness of using simulations in language-training in responding to emergency situations. Learners from three universities of applied sciences participated in language projects from 2018 to 2023: students from Tallinn Healthcare College, Estonian Academy of Security Sciences and Tallinn University of Applied Sciences. The projects utilized a tandem approach, which pairs learners with native speakers to enhance their foreign language skills. The simulations provided a realistic and immersive learning experience for participants, and the results showed that this approach significantly improved their ability to effectively respond to emergency situations in both Estonian and Russian. Project participants acquired the following professional and language skills: response in Estonian and Russian in crisis situations, communication with a client, administering first aid, asking personal data and giving/asking directions in the foreign language. The series of the language-learning events highlighted the importance of incorporating simulations in language education, the benefits of tandem language-training and fostered motivation. Furthermore, the results demonstrate that simulations can provide a valuable tool for language teachers, as they create a realistic scenario for learners to practice their language skills in authentic environment.
