about image


I am an Assistant Professor in the School of Design at the Hong Kong Polytechnic University and direct the Responsible Design group. Residing at the intersection of Human-Computer Interaction, Learning Sciences, and Design, my research mainly focuses on studying and designing playful technology-mediated learning experiences for young people, investigating the roles that social context plays in supporting such learning, and innovating design research in educational contexts. Some of my research and design practices also go beyond learning contexts and extend to broader HCI research, such as reflecting on HCI research methodologies and addressing emergent technology-related challenges in people’s everyday life.

Before joining PolyU Design, I was a Temporary Research Faculty in the Creative Communities research group at the University of Colorado Boulder and once a research intern in the Berkman Klein Center for Internet and Society at Harvard University. I earned my Ph.D. in Information Science from the University of Colorado Boulder, Master's degree in Design from Shanghai Jiao Tong University, and Bachelor's degree in Industrial Design from Zhejiang University.

Physical Play as a Medium for Computational Learning

We are systematically investigating how physical play can be leveraged to provide active, social, and playful computational learning experiences for young people, including (1) how physical activities, learning, and technologies can be combined to support learning purposes for young people, (2) how computational thinking concepts and skills can be incorporated into physical play, and (3) designs of educational technologies and curricula that bring young people outdoors for computational learning through physically active ways. Taken together, this work lays a solid foundation for future educational research, pedagogical innovations, and learning technology designs that leverage physical play in CS education for young people.

Parental Involvement in Children's Learning with Technologies

Parents play essential roles in supporting children's learning with technologies. Through two interview studies, we explored how parents mediate children's interaction with educational technologies using computational toys and kits as a case study and how parents facilitated children's learning with technologies during the COVID-19 pandemic. Building on the Family Creative Learning project (Roque, 2016) where families co-create with computing, we further examine how families leverage “funds of knowledge” in creating computational projects and reflect on the theoretical framings of parental involvement in children's engagement with educational media, and by extent, general media in everyday life.

Computational Toys & Kits for Young Children

As more education researchers, policymakers, and industry leaders have recognized the importance of helping young people cultivate computational thinking, we explored how computational toys and kits are designed to support young children’s computational learning and how parents support their children’s learning with these kits at home. Our findings reveal the commonalities across existing kits and highlights ways for designers and researchers to expand the possibilities for children to create, explore, and play with computing. In addition, we reveal the various roles parents play, their expectations, and concerns in supporting their children's learning with coding kits. [In Progress]

Critical Computational Literacy

As a powerful tool for creating content, computer programming has been employed by some civic programs to engage youth in examining and challenging sociopolitical injustices. We present a case review of youth civic engagement programs based on the lens of critical computational literacy (CCL), a conceptual framework that calls for people to challenge social injustices using computational skills. We examine the program features and how participants were exposed to the computational and critical aspects of CCL. We further reflect on design implications for civic researchers, organizations, and computing educators to cultivate CCL in young people.
