We are delighted to welcome back our alumni and colleague Prof Bai Jing from Nanjing University. Accompanied by Prof Ying Chan, Prof Bai visited TELI for an exchange of knowledge in innovative teaching and learning. We introduced the HKU e-learning ecosystem from infrastructure, IT development to multimedia production. Prof Bai also shared her experiences in promoting technology adoption at various institutions in Hong Kong and Mainland China. We hope to continue learning from each other!
