"Girls, Boys, and Media:
A Gender and Digital Life Toolkit for Educators
Messages about gender roles come from all directions, but some of the most influential messages come from the media. For today's kids, that means not just the TV shows, movies, and ads they see, but all of the messages and images they create and receive from their friends.
Use this toolkit to help students reflect on gender stereotypes: where they come from, how we learn them, and how they can shape the media that we consume and create."
