Created and funded by The Hong Kong Jockey Club Charities Trust, “Fun to Move@JC” is a 5-year pilot project co-created by The Chinese University of Hong Kong, and co-organised by The Hong Kong University of Science and Technology and The Hong Kong Applied Science and Technology Research Institute. The Project was launched in September 2017. With the aid of school and family collaboration and state-of-the-art technology, the Project aims to develop a sustainable model that enhances primary students’ physical activity level, improving their efficacy and motivation in sports through creating systemic changes in their lifelong physical activity attitudes and habits. The Project serves 35 participating primary schools, reaching over 30,000 primary school students and their parents. In the long run, we hope the valuable experiences we can accumulate from this pilot could be further developed to facilitate the development of positive behavioural and psychosocial well-being of students in Hong Kong.
