Can we measure everything? What is the role of privacy? Can we count beauty? Is data always fair? This course explores participation as the foundation of online citizenship. Participation is based on data literacy and community awareness. Through online assignments, peer reviews and video chats, students form communities of explorers and innovators who challenge data culture through creative interventions including surveys, visualization, animation, video, interaction design, music and other forms of digital expression. Assignments are based on readings about media theory, abstraction, interactivity, design theory, archives, performance, identity, privacy, automation, aggregation, networking, diffusion, diffraction and subversion.
