Teacher Education Division Officers

President George Bartuska

George Bartuska is a veteran engineer of 25 years, and now a veteran Earth-Space Science teacher of 12 years. In addition, George has taught AP Environmental Science, Marine Science, Biology, Engineering Technology and Aerospace Technology. This past summer he retired from public school teaching and is presently finishing his Doctoral Dissertation with plans to transition into teaching at the college level. He is a State of Florida - Space Foundation Teacher Liaison representative and also involved with the USAF Space and Missile Museum at the Cape Canaveral Air Force Station. George also serves as Academic Advisor to USAF Civil Air Patrol and teaches adult Coast Guard Auxiliary members in mandated Coastal Marine Weather and Hurricane Preparedness courses. A veteran of the U.S. Navy, he served aboard the U.S.S. John F. Kennedy as an aircraft safety equipment mechanic. Since then, George has emphasized meteorology, oceanography, and space sciences education. For the past 5 years, he has facilitated the Sea Perch Challenge Grant through Embry Riddle Aeronautical University for students to build and operate Remotely Operated Vehicles (ROV) underwater robots. He also obtained grant funding for a GPS Tracked High-Altitude Balloon Launch from the Motorola Corp. and funding from the Polk Education Foundation for GPS Tracked Student Ocean Drifters and a GPS Tracked Miniboat Sailboat, as well as a SPLASH Grant from the Southwest Florida Water Management District to purchase an Aquifer Groundwater Model and other water resources teaching instrumentation.


Vice President Christopher Roemmele

Christopher Roemmele is an Assistant Professor in the Earth and Space Sciences Department at West Chester University of Pennsylvania. He teaches Science Methods to the Early Grades Prep and Middle Grades Prep majors, as well as Introductory Geology, and supervises student teachers. He received his PhD. from the Earth, Atmospheric, and Planetary Sciences Department at Purdue University in West Lafayette, Indiana, focusing on geoscience education.  He received his Master's in Science Education from Kean University, and Bachelor's in Geoscience from Franklin and Marshall College. He has published in NSTA's Science Teacher and Science Scope, and NESTA's The Earth Scientist.  Christopher taught high school and middle school earth science for 15 years in New Jersey, during which time he was member of, and President of the New Jersey Earth Science Teachers Association.  Christopher's research examines the connection between cognitive and affective behavior of introductory geology students and how their geologic worldview is impacted through the use of demonstration videos and virtual field trips, and active learning environments.  He also partners with the Science Learning Research Group of University of Maryland and Temple University with the use of Model-Evidence-Link activities to engage students in argumentation and conceptual change of socioscientific issues.


Secretary/Treasurer Bridget Mulvey

Dr. Bridget Mulvey earned her Ph.D. in Curriculum and Instruction from the University of Virginia and a master's degree in geological sciences from Indiana University at Bloomington. She teaches courses in science education for preservice and inservice teachers. She taught K-16 science for 11 years in formal and informal settings and has taught science methods at undergraduate and graduate levels for 10 years. Her teaching and research focus on teachers and students doing science practices / inquiry, understanding characteristics of scientific knowledge and inquiry, and using technology to support the doing of science and/or to promote science content understandings. Overall, she seeks to improve science teaching and learning for underrepresented groups with a focus on minority, female, and special education teachers and students.
