Paul Numedahl
Paul Numedahl, Ph.D., is a science educator who serves as Products and Services Lead with BSCS. He holds degrees in biology and science education from the University of Northern Iowa and University of Iowa respectively. Prior to joining BSCS in the spring of 2008, Dr. Numedahl taught secondary school science in both urban and rural school districts and was a district level administrator. In addition, he has held both visiting professor and assistant professor positions in science education at the college level.
Post-secondary experience includes teaching both undergraduate and graduate level education courses and research in the field of science education. In addition to teaching and research, Dr. Numedahl has been involved with numerous externally funded professional development projects for elementary and secondary science teachers. His early work centered on secondary math and science teaching in rural school districts and involved the integration of math and science instruction via a problem-solving pedagogical model. Most recently, Dr. Numedahl was involved with Science Teacher Enhancement for the Pikes Peak Region (STEP-uP) project. This eight-year initiative, funded by the National Science Foundation, focused on science education reform in five urban school districts. Since the project's inception, he was extensively involved with the development and facilitation of institutes and courses designed to substantially enhance science content and pedagogical knowledge of practicing teachers.
Dr. Numedahl has a broad range of scholarly interests that include the areas of teacher beliefs concerning science as a discipline and the teaching of science. Consequently, he has presented papers on teaching beliefs and conceptions at various national conferences including the Association of Science Teacher Educator (ASTE), Association of Teacher Educators (ATE), and the National Association of Research in Science Teaching (NARST). Secondary interests include effective instructional approaches that explicitly teach and infuse the nature of science into science curriculum and the influence such methods have on student perceptions of the scientific endeavor and content area understandings.
Thomas T. Peters
When it comes to STEM education, Tom Peters is a change maker. Tom facilitates change by supporting schools and organizations in becoming more effective environments for thought, collaboration and inquiry. STEM education, when executed well, opens the floodgates of interest and innovation for new generations of thinkers and doers.

Bonnie Wood
Dr. Bonnie Wood received her 1968 BA in Biological Sciences from Wellesley College in Massachusetts followed by a 1975 PhD in Neurobiology and Behavior from Cornell University Medical College Graduate School of Medical Sciences in New York City. After a postdoctoral fellowship in Behavioral Biology at the California Primate Research Center in Davis, California, she held a variety of positions before joining the faculty at the University of Maine at Presque Isle in Northern Maine.
Her research focus is reform of science pedagogy and, among other changes in her own classes, she erased the arbitrary boundary between "lecture" and laboratory. She currently teaches all of her courses using "lecture-free teaching," a term she coined to describe her classroom style. Over the years Wood has published articles in the Journal of College Science Teaching and The American Biology Teacher as well as chapters in several books. Her 2009 NSTA Press book entitled Lecture-Free Teaching: A Learning Partnership Between Science Educators and Their Students organizes all of her thoughts about science education reform between two covers. Using her book as a guide, she leads workshops around the U.S. and internationally.
