This document discusses a case study on the construction of young female identities in media. It prompts the reader to analyze examples of how teenage girls present their own identities on social media (e.g. Zoella, Kylie Jenner), and how media institutions construct representations of teenage girls (e.g. music videos, advertisements). The reader is asked to consider how different audiences respond to and consume these identities using reception theory. They should also explore whether the representations reinforce or challenge dominant ideologies about teenage girls and their use of new media technologies. A range of media platforms and examples are provided to aid the reader's research on this topic.
