The word colloquium (when translated from Latin) means a conversation with the goal to evaluate the knowledge of learners and enrich their experience of this or that issue while communicating in an informal manner with a professor or instructor. In winter 1994, I participated in an unforgettable event – an international colloquium on the topic, Korczak: caring about education, which was organizedin the city of Sion, a capital of the canton of Valais, Switzerland. A year later, Swiss Korczak Society published a book in French under the title, “Shock in the world” edited by Professor V. Halperin (1). The program was full of interesting and challenging meetings. Especially I remember one of them with the topic that sounded casual, informal, and cheerful: "How educators should talk, debate, travel, share joy and sadness with children, and how they can still remain themselves and feel happy."
