Our strategic and innovative integration of physiological computing, STEM, and career enrichment to engage upper elementary students in developing STEM+C self-efficacy and career aspirations will advance research in STEM+C education in several ways. By combining an innovative technology experience and authentic career exploration activities, we will develop elementary-level physiological computing educational resources that currently do not exist and test the implementation with more than 20 afterschool educators and 350 upper elementary students, most from historically underrepresented groups in Alabama. The impact of this project will be further enhanced by leveraging existing community partnerships outreach programs, which will create opportunities to attract and sustainably engage young students in STEM+C activities throughout and beyond the project span. Our project efforts will have a long-term impact on preparing STEM+C problem solvers to address the talent shortage challenges.
