Pre-service teachers (PSTs) often lack the self-efficacy necessary to effectively implement STEM education into their classrooms. Undergraduate research experiences (URE) can help fill this void by providing opportunities for PSTs to engage with STEM content and K-12 students in a field-based research context. This case study details the impact a URE had on PSTs' STEM self-efficacy and views on research. The URE consisted of STEM curriculum development, teaching the curriculum at a local middle school, gathering research data, and presenting results at academic conferences. Participation in the URE positively influenced the PSTs' self-efficacy in STEM and changed their perceptions regarding research. This research provides practical value to educator preparation programs (EPPs) as an option to enhance STEM education for PSTs.
