Using arts-informed ethnographic approaches, theatrical techniques and a feminist/performance studies lens, this study analyzes the construction of US girlhood from the perspective of girls ranging in age from fourteen to seventeen by examining their original artistic creations and performances. Placing the artifacts of girl-created culture and the girls' representations, which I view as a performative practice, at the heart of my study, I connect girlhood studies to Butler's gender performance theories and to the larger field of performance studies. Rather than strictly analyzing these original works myself, I involve the girl participants as co-theorists in the analysis of the resulting artistic creations as a performance of girlhood. Through our theory building sessions, we aim to discover a nuanced understanding of girlhood and how gender identity can be performed by adolescent girls, as well as how artistic and theatrical practices can serve to assist youth in exploring complex issues. The adolescent female participants serve as active writers and performers of girlhood and through their writing and performances demonstrate their understanding of what it means to be a girl in contemporary US society. In viewing the girls as theorists, I demonstrate their capabilities while honoring their experiences and knowledge, an approach I believe should be more often employed in academia and in everyday life. Specifically, my study's central research question asks: how do US girls consume mass media representations of girlhood and reproduce or subvert these representations? In what ways do girls perform their understandings of their own identities and what it means to be a girl in contemporary US society through their creations of original art and literature, live theatrical pieces, and digital cultural practices? These works include theatrical performances, creative writing, self-portrait sculptures, and blogs/journals. Additionally, I conduct and analyze both solo and group interviews. I assert the importance of creative space and theatrical/artistic practices as tools with which girls can examine and challenge girlhood and gender discourses.
