Critical math and science educators have argued for pedagogies that focus on equity, social justice, and the identities of learners. To inform debates about the purposes and values of math and science pedagogy, we need to better understand how different kinds of curriculum and instruction are taken up by learners over time. This study examines the ways one Latinx immigrant learner, Calvin (a pseudonym), constructed the values and purposes of his earlier math and science learning experiences, as an adult hoping to pursue a career in science. Narrative analysis is used to explore the ways Calvin made sense of his learning of math and science in high school, in community colleges, and on his own. Drawing on the construct of appropriation, we examine the conceptual tools Calvin took up from different math and science pedagogies (reform, critical, and traditional) in narrating his desire to explore and understand scientific phenomena. Narrative frames position Calvin with greater or lesser agency as he navigates different learning environments, imagines possible futures, and constructs the purposes of science and mathematics. The narratives of Calvin's learning illustrate the conceptual tools he appropriates from reform and social justice pedagogies: real-to-my-life mathematics, learning as connecting and imagining, harder-but-easier math for a purpose, and the ways reading and writing the world can be applied to imagining planets and the universe. The analysis suggests the usefulness of restorying as a way to explore how our pedagogies interact with learners' subjectivities, desires, values, and purposes for learning.
