Created and funded by The Hong Kong Jockey Club Charities Trust, and co-created by The Education University of Hong Kong, Massachusetts Institute of Technology and City University of Hong Kong, CoolThink@JC organised its 5th annual Competition. It has attracted more than 200 teams across different primary schools, the highest participation number ever. Besides showcasing their clever computational thinking, programming prowess, problem-solving skills, and teamwork, students also impressed the judges by incorporating artificial intelligence in their designs.
