The Cheonggyecheon Museum's second-half 2026 programme, 'Talk Talk Talk Cheonggyecheon', is a live online lesson for elementary school-age groups at Seoul community child-care centres and school after-care programmes. It is not open to individual family applications. The programme explores the historical and ecological changes of Cheonggyecheon from the Joseon era to the present through interactive teaching and activity sheets.
The organiser lists four Wednesdays: August 26, September 30, October 28 and November 25, 2026. The November 25 session has two time slots, 14:30–15:30 and 16:00–17:00, Korea time. The full series contains eight lessons over four days. Participation is free and activity sheets are provided. Learners join from their own institution, rather than visiting the museum.
One institution participates per lesson, with groups of 15–20 children. The institution's staff member applies on Seoul's Public Service Reservation system by searching for the museum's programme. The official booking list gives an enrolment window of August 3–November 16, while the detailed recruitment notice says applications are accepted until the first-come allocation is filled. The current booking screen is authoritative for availability.
The participating institution needs a room, internet connection and equipment suitable for two-way Zoom instruction: computer, microphone, webcam, display and sound. Check activity sheets and equipment before the class. For questions call 02-2286-3402 or 02-2286-3452. An advertised date does not guarantee a free spot.
