As part of the accredited Erasmus+ program project, the activity "job shadowing" took place, during which two of our teachers spent 5 days observing the teaching process at a partner school in Terrassa, Spain. The mobility included observations in subjects such as English, French, Spanish, and Catalan languages, biology, computer science, as well as various workshops and activities that took place both at the school and outside of it. We had the opportunity to exchange opinions, observations, and compare the positives and negatives of teaching these subjects. At the same time, we were able to share effective teaching methods, explore the positive impact of teambuilding activities, develop intercultural awareness, and deepen our knowledge of national identities. Part of the mobility also included exploring the historical, cultural, and natural landmarks of the Catalan cities of Terrassa and Barcelona. Special thanks go to our host, Silvia, who was the mentor for the entire mobility, as well as to all the other teachers who made the experience both inspiring and enriching. We shared our experiences and insights with our colleagues, presenting our reflections from the mobility.
