Introduction
The Computer Science Investigations (CSI: Cincinnati) project brings undergraduates in computing-related fields into urban STEM classrooms to interact with and teach high school students. CSI: Cincinnati is funded under the National Science Foundation's Broadening Participation in Computing program and its goals include: (1) introducing underrepresented populations of high school students to computing topics, field of study, and the profession in a fun but challenging way, and (2) training computing undergraduates to mentor youth and teach computing topics.
