This study examined the manner in which extracurricular activities impacted the acculturation of first-generation adolescent males. Specifically, the project focused on the influence of organized high school soccer on the development of first-generation adolescent Korean American males. Eight adolescent participants, ranging in age from fourteen to eighteen were given semi-structured interviews within their high school. Based on this limited population, qualitative data was obtained and grouped into clusters of meaning which allowed for insight into these participants' experiences. The literature review for this project focused on acculturation theory, particularly integration theory and childhood immigration. It also reviewed theories of development, perceived benefits and limitations of adolescent extracurricular involvement, as well as the history of Korean immigration and acculturation to the United States. Based on the eight interviews conducted, this population clarified the numerous ways in which extracurricular involvement impacted English language development. These students also reported what attracted to them to become involved with high school soccer and the role that participating had on expanding their social circle. Participants spoke of the influence which extracurricular involvement had on their academic performance and clarified their feelings relating to their school's perception of their athletic involvement. The students also addressed how they believed their Korean background influenced their relationship with their teammates. The analysis of this small sample population revealed the extent to which English language development is positively effected by extracurricular participation. This benefit combined with the enlargement of peer contacts which accompanies athletic involvement appears to increase these participants general comfort level within their school. Numerous students also clarified how the work ethic they developed through athletics is one variable which positively impacted their academic drive. Lastly, these participants revealed what attracted them to become involved in extracurricular activities; insight which could likely benefit future research and community practice.
