The Medal will be awarded at a Ceremonial Session of the 2020 AAPT Winter Meeting, in Orlando, Florida. The Oersted Medal recognizes his outstanding, widespread, and lasting impact on the teaching of physics through his contributions to the development of active learning strategies and materials to moti- vate students—especially those using computer-based tools—and his extensive dissemination activities. In connection with the award, Sokoloff will deliver a talk, “If Opportunity Doesn’t Knock, Build a Door: My Path to Active Dissemination of Active Learning,” at the Orlando meeting. Sokoloff is Professor of Physics, Emeritus at the University of Oregon. He earned his B.A. at Queens College of the City University of New York and his Ph.D. in AMO Physics at the Massachusetts Institute of Technology. For over three de- David Sokoloff cades, he has studied students’ conceptual understandings, and developed active learning approaches (with NSF and FIPSE support). These include Interactive Lecture Demonstrations (ILDs) and the four modules of RealTime Physics: Active Learning Laboratories (RTP), both published by Wiley and co-authored by Priscilla Laws and Ronald Thornton. His work “If Opportunity has been published in the American Journal of Physics, the European Journal of Physics, Physical Review, Physics Educa- Doesn’t Knock, tion Research and The Physics Teacher. He has conducted numerous international and national workshops to disseminate Build a Door - My these active learning approaches to secondary and university faculty. Since 2004, he has been a member of the UNESCO Path to Active Active Learning in Optics and Photonics (ALOP) team, presenting workshops in more than 30 developing countries in Af- Dissemination of rica, Asia and Latin America. He is contributor to and editor of the ALOP Training Manual. The ALOP Team was awarded the 2011 SPIE Educator Award. He was awarded the American Physical Society (APS) 2010 Excellence in Physics Educa- Active Learning ” tion Award (with Priscilla Laws and Ronald Thornton) and the American Association of Physics Teachers (AAPT) 2007 Robert A. Millikan Medal. He has been a Fulbright Specialist in Argentina (2011) and Japan (2018), is currently a member Tuesday, January 21 of IUPAP Commission 14 (International Commission on Physics Education), and has served in AAPT’s Presidential Chain 10:30 a.m.–12:30 p.m. (2009-2012). Grand Sierra E Named for Hans Christian Oersted, the Oersted Medal recognizes those who have had an outstanding, widespread, and lasting impact on the teaching of physics. The recipient delivers an address at an AAPT Winter Meeting and receives a monetary award, the Oersted Medal, an Award Certificate, and travel ex- penses to the meeting. The award was established in 1936. 2020 Melba Newell Phillips Medal Awarded to Richard W. Peterson The 2020 Melba Newell Phillips Medal will be awarded to Richard Peterson, University Professor of Physics – Emeritus, Bethel University, St. Paul, Minnesota. Peterson has brought to AAPT’s executive level leadership a passion for experi- mental physics and its impact on the lives of students in high school, introductory and advanced laboratories. Follow- ing work with the AAPT Apparatus Committee (starting in 1976), he was NSF Principal Investigator for AAPT’s Lab Focus-‘93 that sought to reinvigorate all physics teaching lab experiences. Later he helped form the AAPT Laboratories Committee with its emphasis on encouraging more effective physics laboratories. While an AAPT leader, he worked with others in the formation of ALPhA (Advanced Laboratory Physics Association) as a charter ALPhA Board member - help- ing organize the first ALPhA national conference (2009) at the University of Michigan. He received the American Physi- Richard W. Peterson cal Society’s (APS) prize for outstanding research at an undergraduate school and was elected an APS Fellow in 2005. He was recognized with the Jonathan F. Reichert and Barbara Wolff-Reichert Award for Excellence in Advanced Laboratory “Changed . by a Instruction in 2017.He served six years on the AAPT Executive Board as Secretary and four years (2003-2007) within the high and humbling Presidential track - followed by three years as the first AAPT Meetings Committee Chair. His many years of dedicated and creative leadership have had a lasting impact on AAPT, how we do advanced labs as physics faculty, and on the lives calling” of countless students. Tuesday, January 21 He was an undergraduate at the U. of Wisconsin - River Falls, with a Ph.D. in physics earned at Michigan State - followed 10:30 a.m.–12:30 p.m. by postdoctoral positions in the Physics Division at Los Alamos. His formative decade in physics teaching was at Western Grand Sierra E Illinois U., with the last
