Launched by the Chinese University of Hong Kong, uReply is an online student response system (SRS) specifically designed for mobile devices. This system enhances the interaction between teaching and learning through mobile technology, fostering students’ proactive engagement. The highly interactive and participatory learning environment that the system offers promotes the modernization of educational paradigms. uReply has gained widespread recognition across universities in Hong Kong and has evolved into a versatile educational platform through continuous development and expansion. It not only supports self-directed learning but also incorporates gamification and location-based interaction, significantly expanding educational opportunities.

The basic features of uReply include single and multiple question sessions, activities, and assessments, which together create a comprehensive and immersive interactive learning environment. Notably, uReply GO introduces a geolocationbased learning trajectory, linking action points with questions on an online map to enhance the practical and experiential aspects of learning. Meanwhile, uShare facilitates multimedia communication between teachers and students, significantly enriching the forms of interaction and greatly improving the efficiency and clarity of information exchange, making the learning process more engaging and intuitive.

The design of uReply adheres to pedagogical principles, allowing teachers to customize educational activities to fit their teaching goals and to meet the specific needs of their students. Its asynchronous learning feature provides students with a personalized educational experience, while gamified elements like speed challenges and peer reviews not only make learning more engaging but also increase student motivation and participation.
