JUTAKI Ltd. - Hungary Expert for Teachers, in collaboration with the Croatian Language Twist Language School, successfully conducted a four-week adult learner mobility program in Rovinj. The program welcomed 38 participants from Hungary, Slovakia, Serbia, and Malta, focusing on the exploration of opportunities in adult learning and the acquisition of new knowledge across various topics. During the first week, from July 13-21, participants delved into 21st-century skills, the application of ICT (Information and Communication Technologies), inclusive education, and the potential for collaboration within groups, along with an introduction to the world of invisible theater. The second week, from July 20-28, focused on personality development, flow, gamification, and the relationship between music and language learning. In the third week, from July 27-August 4, participants explored project-based learning (PBL), artificial intelligence (AI), assertive communication, and the role of games. The final week, from August 3-11, centered on maintaining long-term motivation. In addition to the educational programs, participants had the opportunity to engage in cultural activities, exploring the beauty of Rovinj and bonding through playful evening events. The experiences and knowledge gained during the mobility not only contributed to the professional development of the learners but also helped strengthen international relationships. Special thanks go to the Language Twist Language School and the city of Rovinj for their warm hospitality, as well as to the EU-supported Erasmus+ program, which enabled us to create such a rich and meaningful experience for our adult learners.
