Our school has joined the Jockey Club “Flipped Learning” Pilot Project organized by HKBU and CUHK since September this year. Six Mathematics teachers of junior forms have taken part in the project and tried to apply “Flipped Learning” strategy in their teaching, which is a great strategy to enhance students’ learning motivation. The pioneering teachers shared the approach and their learning in an open lesson in Class 2G on 14th May,2021. Both students and teachers who observed the lesson had a memorable and insightful experience.
