The “ARDIS” audio studio presents an audiobook featuring three works by the outstanding Polish educator Janusz Korczak: “Educational Moments,” “Playful Pedagogy,” and “The Diary,” written in a ghetto during World War II. In his literary works, Korczak addressed the most general questions of upbringing and turned to a wide audience interested in educational issues. He became widely known not only as a writer, but also as an outstanding expert in a child’s psyche, an innovative teacher, and a public figure. His pedagogical legacy is still extremely relevant today. We must not forget this as we search for new ways in pedagogy and new solutions that correspond to our time.
