Parents play essential roles in managing, mediating, and supporting children’s interaction with technology, such as being a teacher, project collaborator, and scaffolder. Simultaneously, children demonstrate much agency during shared engagement with media, such as teaching their parents how to use technology and defending their inputs. Building on our work about parent-child interaction around learning technologies, we are exploring parent-child joint media engagement (JME) and aim to facilitate more designs of productive JME experiences and technologies for families.
