Although quantitative reasoning (QR) is central to general education, many college students lack fundamental numeracy skills. In response, The City University of New York established a QR faculty development program that trained instructors across the disciplines through teaching exercises, guided discussions, hands-on activities, the development of instructional/assessment materials, and feedback from mentors and peers. Ten cohorts, 2010–2019, responded to surveys that evaluated their motives for participating and the extent to which they felt their goals were met. Faculty joined the program due to factors including their concern for students, their commitment to QR instruction, and their desire to build professional networks. Program completers reported a better understanding of QR, a greater commitment to QR instruction, increased awareness of tools and techniques (e.g., progressive pedagogies, active learning and constructivist approaches), a clearer sense of students’ needs, a commitment to assessment, and strong engagement with CUNY’s multidisciplinary, multi-institutional QR community. Overall, the perceived benefits of the program match participants’ motives for joining. Respondents’ comments suggest that faculty development for general education requires motivated participants, opportunities for networking, thoughtful discussion of readings and videos, modeling of best practices, a student-centered curriculum, sensitivity to participants’ backgrounds, adequate incentives, effective mentorship, and institutional commitment.
