This dissertation shares findings from a yearlong qualitative case study of Young Voices Rise (YVR), a diverse spoken word poetry group in the urban Southwest. The study examined the group's characteristics and practices, adolescent members' views of their writing and themselves as writers, and changes members attributed to their experiences in YVR. Data sources included interviews with six adolescent poets and two adult teaching artists, observations of writing workshops and poetry slams, collection of group announcements through social media, and collection of poems. Sociocultural theory guided the study's design, and grounded theory was used to analyze data. This study found that YVR is a community of practice that offers multiple possibilities for engagement and fosters a safe space for storytelling. The adolescent participants have distinct writing practices and a strong sense of writing self; furthermore, they believe YVR has changed them and their writing. This study has several implications for secondary English language arts. Specifically, it recommends that teachers build safe spaces for storytelling, offer spoken word poetry as an option for exploring various topics and purposes, attend to writers' practices and preferences, encourage authentic participation and identity exploration, and support spoken word poetry school-wide.
