Rann Bar-On

Rann Bar-On is a Senior Lecturer in the Department of Mathematics at Duke University, specializing in early undergraduate mathematics education. He holds a PhD in Mathematics from Duke University (2009) and a Master of Mathematics from the University of Warwick (2003). His work focuses on creating inclusive and supportive learning environments, particularly for students from minoritized and underprivileged backgrounds. He has redesigned calculus courses to eliminate timed assessments, emphasizing continuous feedback and collaborative learning through labs and group projects.

Key initiatives include integrating real-world applications (e.g., climate change modeling, public health data analysis) into calculus curricula and fostering a culture of safety and equity in mathematics classrooms. His teaching philosophy prioritizes deep conceptual understanding over rote memorization, supported by a team of TAs, graders, and the Academic Resource Center. Student feedback highlights his success in reducing stress and improving persistence in STEM pathways. The DFW (Drop/Fail/Withdrawal) rate in his courses dropped from 15% to under 5% following these reforms.

Bar-On’s contributions include developing innovative lab materials for calculus courses (Math 105L/106L) and mentoring dozens of undergraduate advisees. He has been recognized with Duke’s Advisor of the Year Award (2017) for his dedication to student support and academic guidance.
