Reaction or ‘react’ videos are a popular YouTube genre in which an individual or small group analyzes a piece of media, drawing on their personal and specialized knowledge in an informal, often highly emotional way. For educators and learners alike, reaction videos offer a way to approach personal learning, develop digital and media literacies, and ground their learning in personal identity and community connection. In this workshop, participants will discuss key components of reaction videos as a genre, practice reacting to a piece of media, and leave with ideas for using reaction video concepts in their own teaching.
