Centre for Continuing Education has cooperated with the Education and Youth Affairs Bureau to provide professional development activities for in-service teaching staff to improve their job performances and enhance their professional skills. In 2019, we launched more than 10 courses with different themes, aiming at in-service teaching staff of different subjects and levels. The staff can promote their improvement in curriculum development, teaching strategies and personal development. In addition to theory-based teaching, group discussion and information sharing is inserted in the lectures that the in-service teaching staff can acquire the knowledge of the themes.
