Nobel Prize winner Carl Wieman brought his message to nearly 100 USC faculty members that current methods of teaching subjects such as physics, chemistry and engineering are wrongminded and inefficient.
The 2001 physics prize winner, whose appearance was sponsored by the USC Viterbi School of Engineering, USC College and the USC Center for Excellence in Teaching on Oct. 13, was introduced at the Andrus Gerontology Center by Eugene Bickers, vice provost for undergraduate programs.
Wieman, a professor at the University of British Columbia, documented how the traditional science lecture delivered to quiet note takers was at loggerheads with cognitive theory and brain research.
He heads the Carl Wieman Science Education Initiative and is chair of the board of science education at the National Academy of Sciences. He has won numerous teaching prizes, including the Oested Award and the 2004 Professor of the Year Award. He has spread his message of science-based science education for years.
Learning a discipline such as science requires not just mastery of information details, he said, but actual brain change. Tests on students in lectures consistently showed dismally low rates of assimilation of information — rates that remain low regardless of the skill of the lecturer and the talents of the students.
Part of the problem is the intrinsic difficulty of the material. Learning to be a scientist requires thousands of hours of work in adapting thinking to the discipline.
For years, Wieman has attempted to develop a new model of instruction, one that he believes is more attuned to human abilities, such as the peer instruction system partially based on the work of fellow physicist Eric Mazur. In that system, large audiences are divided into small groups.
Such techniques, Wieman said, consistently produce better results.

The Wall Street Journal highlighted the $200 million naming gift from USC Trustee and alumnus David Dornsife and wife Dana Dornsife to the USC Dornsife College, and the $110 million gift from USC Trustee and USC Viterbi School alumnus John Mork and wife Julie to create the USC Mork Family Scholars Program.
KPCC-FM reported that this fall USC will offer Persian language courses for the first time. A $250,000 grant from the Farhang Foundation helped to establish the program. Bruce Zuckerman of the USC Dornsife College said he has many students interested in the Persian language, culture and region. “The Iranian region is one that has great impact on our lives today and has had great impact going back into ancient times,” he said. The story noted that USC and the Farhang Foundation hope to raise more money to create an Iranian studies minor. Payvand also featured the new courses.
American Songwriter ran a Q&A with Christopher Sampson of the USC Thornton School about the school’s Popular Music program, which Sampson founded. He noted that the program has been available as a major in Songwriting since 2009, and has incorporated a diverse range of musical genres. “We have now established a consistent track record of students having professional success to know that the program gets results,” Sampson said. He also highlighted the achievements of Songwriting faculty members Lamont Dozier, Andrea Stolpe and David Poe of the Thornton School.
The Economist featured research by Valter Longo of the USC Davis School finding that short periods of fasting could help cancer patients better tolerate chemotherapy, and may even make treatment more effective. The Globe and Mail (Canada) reported that cancerous tumors are essentially energy hogs. “They need to burn lots of energy just to stay alive,” Longo said. The study was also covered by Irish Independent (Ireland), Magyar Tavirati Iroda (Hungary), Anadolu Ajansi (Turkey), Son Haber (Netherlands), Vietnam+ (Vietnam), Turkish Radio and Television (Turkey) and Romania Libera (Romania).
L.A. Weekly featured research by USC’s Institute for Creative Technologies, which has developed video games based around physical movement for people recovering from strokes or other injuries. The games develop strength in specific body parts. Traditional video games weren’t right for these patients, said the institute’s Belinda Lange. “Often, the fun parts of the game would only be unlocked after a series of other levels, which our patients often couldn’t achieve,” she said. The games are now being tested with physical therapists in three major clinics.
