Together with the students from other countries, we created one international group of 26 diligent students. Within the prepared modules, we were introduced different teaching methods and activities by the lecturers, so we could try ourselves which situations and problems we can encounter in future as teachers. Group work was most commonly used and it helped us to better realize and understand the thinking of other cultures. The common language of the summer school for all the students and lecturers was English. When solving the scientific problems (biology, chemistry, physics), we experienced some funny situations, especially when we lacked the correct vocabulary in English and we replaced the missing term with other, simpler vocabulary in English. The pencil and paper were also a very good aid in international, foreign and intercultural educational environment. When the words were not enough, we helped ourselves by simple drawings and pictures. For many participants of the summer school, it was also the first visit to Prague, therefore, one afternoon was devoted to sightseeing Prague’s dominants and attractions. We were accompanied by the student of Charles University and he showed us, for example, the famous café Slávia, the Charles Bridge, or Prague Castle. The program also included visits in two schools, where we learned about bilingual education and the virtual reality created by pupils from secondary industrial school in Smíchov as their year projects and with the level of their knowledge and their work they surpass even the university students from CTU in Prague. In our free time, we had a good opportunity to get a better understanding of different countries from the perspective of domestic residents – our classmates from the summer school. We also learned a few basic foreign language phrases, for example in Spanish. Thanks to this experience, we were able to realize that despite the seemingly large difference between different cultures, we could always find something that we had in common and the differences were perceived as interesting and very enriching. The most important experience from the summer school for our future vocation was realizing that even if our future pupils are from different countries or from different cultural environments, they can be interested and inspired, when we as their teachers are passionate about subject we teach and we can present them the information in the most interesting way.
