Liberal studies is the centrepiece of the new senior secondary curriculum and will take up at least 10 per cent of the school timetable. But unlike other academic subjects, it does not involve the study of specialist knowledge. Instead, teachers draw on knowledge and ideas from across the curriculum to help students explore contemporary issues. Liberal studies takes an 'inquiry-based' approach to learning, in which students learn independently by tackling open-ended issues and problems. It aims to help them to think critically and become informed and responsible citizens. The subject is divided into six modules: personal development and interpersonal relationships; Hong Kong today; modern China; globalisation; public health: and energy and the environment. Each has several themes. By fostering students' understanding and opinions, it is meant to help them form links among the six topics and the 'other learning experiences' in the curriculum.
