Abstract
Ethnically and gender diverse groups are more efficient, creative, and productive than homogeneous groups, yet women and minorities are underrepresented in the science, technology, engineering, and mathematics (STEM) workforce. One contributor is unequal access to high-quality STEM education based on socioeconomic status and race, which we may be able to address through inquiry-based out-of-school time programs. Here we describe a 6-month after-school program that allows an underrepresented community of middle school students to conduct original scientific research that they present at a conference each year. Through qualitative assessments and interviews, we found a trend for increased interest in STEM careers and self-efficacy in participants. Self-efficacy, or belief in one’s ability to succeed, predicts performance and persistence in STEM. Both self-efficacy and interest in STEM careers increased after students presented their research at a conference, highlighting the unexplored importance of dissemination for shaping self-efficacy in K-12 students. Small after-school programs like ours can be easily accomplished as broader impacts by scientists, and well-designed programs have the potential to positively affect change by increasing access and participation in STEM for diverse students.
