How do we systematically include youth, living in underserved neighborhoods, in processes of community development? We can do this through a Mobile City Science Curriculum. This solution supports young people to collect, analyze, and share data from their lived experiences in urban spaces using geospatial and mobile technologies. Young people, participating in this project, will learn and engage in data science around their neighborhoods, using GPS, GIS, and wearable cameras, to create persuasive arguments for how the community could look in the future so that it is more conducive to the interests, desires, and constraints of youth. These persuasive arguments, or "counter-maps," will be shared with local stakeholders, including urban planners, parents, school administrators, and leaders of youth-serving organizations, in public charrettes. Young people and adult professionals and stakeholders will engage in problem-based conversations that respond to the experiences from, representations of, and visions for the community that youth bring to the charrettes.
