Bob Beichner


Professor Beichner received his PhD in 1989 from the State University of New York at Buffalo and joined the NC State Physics Department in 1992 as an Assistant Professor. He advanced through the professorial ranks and was named an Alumni Distinguished Undergraduate Professor in 2003.

He invented the popular Video-Based Lab (VBL) pedagogy, where students examine video clips of motion and watch synchronized kinematics graphs. As part of that effort he created the Test of Understanding Graphs in Kinematics, used by numerous teachers and researchers and serving as a model for similar conceptual assessment instruments. Dr. Beichner and his students have written and evaluated a series of these tests that are in use around the globe. For much of his career he has focused his attention on redesigning introductory physics education. His work laid the foundation for research done on active learning spaces. He initiated the SCALE-UP (Student Centered Active Learning Environment with Upside-down Pedagogies) project in the mid 1990s. This approach has led to changes in classrooms around the world, at institutions ranging from middle schools and high schools to MIT. SCALE-UP has been adopted at hundreds of universities and middle/high schools and had spread to content areas ranging from archeology to zoology.

Beichner has received numerous teaching awards and is a member of NC State's Academy of Outstanding Teachers. He received the Ohaus Award for Innovation from the National Science Teachers Association. He was named the 2009 North Carolina Professor of the Year by the Carnegie Foundation for the Advancement of Teaching and received the 2010 UNC System’s Board of Governors Award. Beichner was named the 2010 National Undergraduate Science Teacher of the Year by the Society of College Science Teachers and the National Science Teachers Association. In 2011 he was awarded the McGraw Prize, the premier honor in the field of education. He was also honored by Congress as noted in the US Congressional Record of September 29, 2011. He is a Fellow of the American Physical Society, the American Association for the Advancement of Science, and the American Association of Physics Teachers. In 2015 he was only the second individual to receive the American Physical Society’s Award for Excellence in Physics Education, which is normally only given to groups or large projects.

Colleen Countryman


Dr. Colleen Countryman is a Teaching Assistant Professor of Physics at North Carolina State University. In addition to teaching and coordinating the introductory calculus-based physics courses (PY 205 and PY 208), she also engages in Physics Education Research. Dr. Countryman specializes in the assessment of educational technologies, such as smartphones in physics labs. She earned her BS in Physics and BA in Mathematics from Canisius College. She went on to obtain her MS in Applied Mathematics from Virginia Tech in August 2010, and completed her PhD in physics at North Carolina State University in May 2015.

Michael Paesler


Professor Paesler earned his BA degree at Beloit College and his PhD from the University of Chicago in 1975. His PhD experimental research on disordered solids was undertaken in the laboratory of Hellmut Fritzsche. In 1976 he was a Guest Scientist at the Max- Planck-Institut für Festkörperforschung in Stuttgart, working with Professor Hans Queisser on the photo-Hall effect in crystalline gallium arsenide. Thereafter he assumed a position as a Post- doctoral Research Fellow in the Division of applied Sciences at Harvard University working with Professor William Paul studying hydrogenated amorphous silicon. Professor Paesler came to NC State in 1980 where he is now Professor Emeritus. From 1997 to 2005 he served as the Director of Graduate Programs. From 2005 to 2012 he served as Head of the department. Professor Paesler's undertakes research in the department's Physics Education Research program. In an effort supported by NC State University's Large Course Redesign program and the NSF Transforming Undergraduate Education in STEM Disciplines Program, his team is studying the teaching laboratory in elementary physics courses. He and his graduate students are investigating the use of so-called kitlabs as an alternative for traditional in-lab teaching systems. The study also encompasses the use of personal electronic equipment (e.g. smart-phones, tablets and laptops) as data-taking and manipulating devices.

Bin was born in the city of Wuhan in China, and he graduated from the University of Science and Technology of China in 2008 with a BS in Physics. After graduation, He worked as a research assistant in the Institute of Physics, Chinese Academy of Sciences studying single molecule biophysics. Then he began his graduate studies at NC State in the fall of 2009. He successfully defended his dissertation and earned his PhD in 2016. Bin is interested in seeing how problem solver's instantaneous confidence changes during the process of solving problems. He has TA experience in Matter and Interactions laboratory sections as well as both algebra and calculus-based traditional physics labs.

Mike was born in Columbus, NJ and graduated from Juniata College in Huntingdon, PA in May 2009 with a BS degree in Physics and a minor in Math. He then got a MEng degree from Penn State's Graduate Program in Acoustics. His research involved designs for wideband tonpilz trandsucers. During his tenure at Penn State, Mike began making educational videos on the science of acoustics for a general audienc and SCALE-UP classroomse. In the fall of 2014, Mike began his graduate studies at NC State, coming back to physics after 5 years as an acoustician. The PER group brought him to NC State as his interests lie in transforming education through technology and the internet. Working on “A comparison of graphical representations of E&M plane waves.”
