Six students from classes IX and XI participated in a Round Square History Lab Pilot event, organised by the Junior and Senior High School of Kogakuin, Japan, on November 16, 2023. The discussion topic was World War 2. As a preparatory work, participating students were asked to put together a short presentation of not more than 2 minutes with one slide per school to present during the session, answering the question, “How did this event impact your country directly and how is it presented in your part of the world”. Around 160 students from 30 schools and 10 countries participated in the event. The students engaged in a lively exchange of ideas, highlighting how the war had not only influenced their countries’ histories but also their cultural identities. They recognised that understanding these diverse perspectives was crucial for fostering global cooperation and preventing future conflicts.
