In this article, I examine the potential for developing preservice social studies teachers' understanding of transformational resistance, Latin@ civil rights movements, and culturally sustaining pedagogy through a project using the film Precious Knowledge. This documentary depicts high school students in a Mexican American Studies (MAS) program using civil disobedience to protest Arizona's ban of the program. The teachers prepared for the screening by reading and responding to scholarly articles on Latin@ school engagement and Chican@ student activism. After viewing the film and engaging in small group and whole class discussions, participants reported that they learned about current and past Chican@ student movements and gained an appreciation for the transformational potential of youth civic activism. The project serves as an example of how methods instructors could use school documentaries or other films as pedagogical tools, and more specifically it suggests readings and instructional activities to pair with such films.
