Adult learners often have difficulty reaching high proficiency levels in a foreign language, and curriculum experts are on a constant quest for innovative practices in foreign language learning. The problem addressed by this study was that even with the implementation of different pedagogical approaches, including immersion and technology integration, students are not graduating with the proficiency levels needed for the increasing demand for highly qualified linguists for national security and global military corporations. Through the lens of diverse Spanish and Indonesian foreign language learners at a prominent language institute in central California, the approach to and experience with learning a foreign language was in an arts-integrated intervention was explored. Guided by Dewey's arts-based pedagogy and Pearson and Gallagher's (1983) Gradual Release of Responsibility framework, the purpose of the qualitative exploratory case study was to reveal students' experiences with an arts-integrated foreign language course. Data were collected via observations, surveys, and individual and focus groups interviews. Employing thematic analysis and with assistance from NVivo software themes indicated that students perceived an arts-integrated language pedagogy as supportive of their language proficiency, engagement, motivation, critical thinking skills, higher-level discussions, and development of target culture knowledge. The findings of the current study reinforced the necessity of exploring unconventional methodologies such as arts-based pedagogy to foster building rational inquiry and cognition while at the same time expanding FL proficiency. Hence, the first recommendation for practice is that art-based instruction should be actively included in the foreign language learning curriculum. Future research should explore different dimensions of arts-based pedagogy concerning student achievement using a quantitative longitudinal study.
