The project developed an after-school program aimed at boosting the STEM career interests of Native American middle-school students. Leveraging digital technologies like virtual reality (VR), augmented reality (AR), and 3D printing, students tackled spatial design challenges through culturally responsive modules. A co-design process with educators, community members, and students helped integrate cultural knowledge into learning environments relevant to Native American youth. The program targeted middle-school students and educators from three Tribal Nations in Oklahoma—Citizen Potawatomi, Otoe-Missouria, and Ponca—and enhanced the infrastructure for STEM education through technology centers and community-focused hackathons. Research on the program assessed its impact on students' STEM identities and career interests using mixed methods. This included observations, focus groups, and both qualitative and quantitative analyses. Findings, resources, and a digital repository were made available online, supporting other Tribal Nations and educators. The insights gained underscored the effectiveness of culturally responsive, community-co-created educational programs.
