Issues related to college access and the need for a pipeline of STEM teachers, provided the impetus for the Ohio Board of Regents (OBR) to issue a call for Ohio universities to design pre-college experiences for high school students with three major goals in mind: (a) improvement in mathematics, science, or foreign language learning; (b) increased attraction to careers as teachers of these subjects; and (c) increased familiarity and readiness for college admission to study these subjects. Through funding provided by an OBR grant we designed and implemented a summer immersion program for high school juniors and seniors in order to meet the needs of this call. Students with self-reported interests in teaching mathematics or science spent two weeks on two environmentally different universities, Miami University and the University of Cincinnati, as a means to expose them to different campus climates while building a greater since of belonging, both culturally and academically. They also earned three PreCalculus credits through rigorous college-coursework. Within this manuscript we describe the program, report pre- and post-test data analyses, provide insights into students' perceptions of the college experience, and reflect on our own lessons learned.
