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.
