L.A. Times: Harvey Mudd Among Colleges Experimenting with “Flipped” Classes (2014-11-17)
The Los Angeles Times has an article about experiments in the use of “flipped classrooms” at Harvey Mudd and other schools, written by Jason Song.
The article features Harvey Mudd professors Darryl Yong and Rachel Levy from math; Karl Haushalter from chemistry; and Nancy Lape from engineering.
In the flipped classroom teaching style, students get traditional lecture material from online videos or podcasts, along with readings. Classroom lectures are replaced by interactive exercises, where students work with the instructor and each other to understand and explore the material from the lectures.
Mudd’s experiment, funded by a federal grant, splits classes into two groups—one using the traditional lecture format, and one using a flipped classroom. Performance appears to be similar between the two classes, although some students have preferred to switch to the more traditional classes.
Other schools doing similar grant-funded experiments include Villanova University, the University of South Florida, and North Carolina State University. The article includes quotes from Villanova’s Randy Weinstein about its program.

Rising Senior Receives Award at MAA’s MathFest (2014-08-15)
Student researchers Ksenia Zakirova ’15 and Michael Cork POM ’16 recently received the Mathematical Association of America (MAA)‘s Outstanding Presentation Award at MathFest 2014, which took place Aug. 6–9 in Portland, Oregon.
Every year the MAA recognizes a small number of students for “especially noteworthy presentations.” Their presentation, Modeling and Exploring Chain Fountain Dynamics, was based on summer research advised by Professor Andrew Bernoff and Postdoctoral Fellow Rob Thompson of the Harvey Mudd Department of Mathematics. Zakirova and Cork were selected from a group of almost 150 student presenters.
The chain fountain is a counter-intuitive physical phenomenon that occurs when one end of a bead chain is dropped from a large height. Rather than falling straight down, the chain first rises in a fountain above itself, seemingly defying gravity. Gravity continues to pull out the “self-siphoning” chain while forcing it above the side of its container into a curved shape. The effect offers a visually fascinating physics problem that has gained recent attention thanks to a “Self siphoning beads“, a viral YouTube video posted by British scientist and TV personality Steve Mould.
“We wondered whether we could create a model for the chain siphon in order to determine its properties and analyze why exactly it occurs,” says Zakirova, a mathematics major. The team studied the dynamics of the problem using differential geometry, partial differential equations and physical and numerical experiments, including letting the chain fall from a third-floor balcony to see how high the siphon might rise. The students discovered that the angle and drag for the chain as it left the beaker crucially affected the observed shape.
Despite significant advancements, Zakirova looks forward to future work.
“The next step in solving this problem is finding the traveling wave solutions and seeing how the solution changes over time,” she says. “We have solved this problem for several special cases. However, a full solution to the hyperbolic PDE is still an open problem.” Another major question, she says, is determining what properties might be missing from the numerical simulations. Finding this will shed light on what conditions are necessary for the chain fountain to occur. Under the supervision of Bernoff and Thompson, Zakirova will continue modeling chain fountain dynamics for her senior thesis project this year.
The research began at Macalester College during an eight-week Research Experience for Undergraduates (REU) led by Bernoff and Thompson. Funding was provided as part of an $800,000 National Science Foundation workforce program grant to the mathematics department that has facilitated the hiring of six postdoctoral fellows and provided summer funding for a dozen undergraduate researchers, including Zakirova.
In addition to Zakirova and Cork, many other Claremont Colleges mathematics students participated in summer research projects at the Claremont Colleges and other top colleges and universities. The Claremont Center for Mathematical Sciences (CCMS) will celebrate the efforts of all these students with a poster session and discussion on Wednesday, September 17, from 4:15–5:15 p.m. at the Caryll Mudd and Norman F. Sprague Courtyard and Gallery in the R. Michael Shanahan Center for Teaching and Learning. Refreshments will be provided.

Simons Foundation Funds Collaborative Research on Swarms (2014-06-02)
Andrew Bernoff, Harvey Mudd College’s Kenneth and Diana Jonsson Professor of Mathematics, recently received a five-year, $35,000 Collaboration Grant for Mathematicians from the Simons Foundation for 2014. The grant has been awarded for his research titled “Discrete & Continuous Models of Non-local Chemical and Biological Systems.”
Bernoff’s work focuses on mathematical modeling of pattern formation in physical and biological systems. On the biological side, he is particularly interested in how birds, fish and insects form aggregations, usually known as swarms. Ultimately he and his collaborators would like to understand how massive destructive locust swarms form, and develop strategies for intervention. On the physical side, he is interested in how intermolecular forces can drive the formation of elaborate labyrinthian patterns in magnetic fluids and related systems.
“Our studies are driven in part by a desire to understand how simple interaction rules between individual molecules or organisms can drive pattern formation on much larger scales,” says Bernoff. “By working with a network of biologists, physicists, mathematicians and a swarm of bright Harvey Mudd undergraduates, we are unraveling the mysteries of the elaborate patterns we see in biological and physical systems.”
Collaborators on the research project include Chad Topaz (a Macalester College mathematician who studies insect motion), Leah Edelstein-Keshet (a noted University of British Columbia mathematical biologist), Maria d’Orsogna (a statistical physicist at California State University, Northridge) and Elizabeth Mann (an experimental physicist at Kent State University), as well as numerous undergraduates from Harvey Mudd and Macalester Colleges.
Established in 1994 by Jim and Marilyn Simons, the Simons Foundation aims to advance the frontiers of research in mathematics and the basic sciences. The goal of its Collaboration Grant for Mathematicians program is to support the “mathematical marketplace” by substantially increasing collaborative contacts among mathematicians working in the United States.
Harvey Mudd College is committed to providing its undergraduates with hands-on research experiences to help prepare them for the rigors of graduate school and beyond. A recipient of the National Science Foundation’s prestigious Award for the Integration of Research and Education, Harvey Mudd College has long recognized the importance of collaborative student-faculty research, setting aside nearly $3 million annually for the purpose. Anchored by a research-supportive curriculum, Harvey Mudd students pursue research and collaborate with faculty both during the academic year and in the summer through the College’s Summer Research Program.
