Click on names below for a brief bio:

AMTA Executive Board

  • Past President: Earl Legleiter (2014-2015)
    Earl Legleiter is a teacher and an independent science consultant with experience teaching traditional and online science course from middle school to high school. He has held leadership positions in the Northwest Kansas Alliance for Science, the Kansas Association of Teachers of Science, and the Arkansas-Oklahoma-Kansas Section of the American Association of Physics Teachers. As a consultant, Legleiter provided a variety of presentations and training, resource dissemination, group facilitation, building client capacity, and technical assistance to schools and districts. He was trained in modeling instruction at ASU in 1995, and has led Modeling workshop in physics, chemistry, and physical science in several states for nearly fifteen years.
  • President: Angela Gard (2014-2015)
    I believe AMTA is on the cusp of becoming a strong national organization. Since my attendance at the AAPT meeting in Omaha in 2012 I recognize the need to strengthen the use of modeling in all content areas. I have held National Board Certification since 1999 and a lifetime membership in AMTA since 2009. Although initially trained in Modeling Physics, I have worked on refining and expanding the Modeling Biology curriculum, originating from Shady Side Academy, for use with the NC Modeling Biology workshops that I lead. As a high school science teacher for 17 years I used modeling pedagogy in my physics, AP physics, biology and AP Biology classes. I left the classroom for three years to work as a Modeling Science Instructional Coach supporting teachers of physics, chemistry, physical science and biology with their implementation of modeling pedagogy. I have now returned to classroom teaching. I hold a MEd. in curriculum and instruction and have worked at the state and local levels in both Washington and North Carolina.
  • President-Elect: Kathy Malone (2014-2015)
    Kathy Malone has been practicing Modeling Instruction in Physics since 1995 when she attended her first Modeling Instruction workshop at Arizona State University. She was hooked on the pedagogy especially after she discovered the improved performance of her students on the FCI. She has promoted the pedagogy by doing summer workshops and conference presentations ever since. Kathy’s desire to learn ‘why” her students demonstrated such improved performance on the FCI led her to enter and complete a PhD in Cognition and Instruction in Physics education from Carnegie Mellon in 2006. During this time she also started a Modeling Teachers Institute at her school, Shady Side Academy, which offered one week introductory modeling instruction courses. Kathy was also instrumental in helping her school switch to a physics first course sequence which stressed modeling instruction in all introductory science courses. Kathy previously served on the AMTA board as secretary. During her time as secretary she instituted the AMTA newsletter, The Whiteboard, and was instrumental in helping AMTA gain NSTA affiliate status.  Kathy served as an Einstein Fellow at the National Science Foundation through March 2014 and as a post-doc at University of Pittsburgh’s Learning Research and Development Center till August 2014.  She is currently an assistant professor in science education at The Ohio State University. Kathy Malone is very excited to work with the executive board as President-Elect to make the most of these opportunities and create additional ones as the country and AMTA meet the new challenges of the NGSS.
  • Vice President: Rex Rice (2014-2015)
    I am a 34-year veteran high school physics teacher, and a 19-year veteran of
    Modeling Instruction. After a class at ASU with some of the original
    Modelers (Malcolm Wells and Larry Dukerich) on scientific reasoning and the
    Karplus Learning Cycle 1984, I became an enthusiastic practitioner of active
    engagement methods in my classes. After moving to Missouri, I returned to
    ASU in the summers of 1995-1997 to be part of the first national training
    session for Modeling Physics. I was one of the original workshop leaders in
    “Phase 2″ of the Modeling Physics program in 1997.
    I have been leading workshops for physics teachers since 1986, through the
    AAPT PTRA program, the Woodrow Wilson National Fellowship foundation, and,since 1997 Modeling Instruction. I am a pioneer of the “physics first”
    movement. I was an early supporter of AMTA, and continue to be an active
    Modeler and Modeling Workshop leader. I would like to continue my service to
    the Modeling community in the leadership chain during the coming years.
  • Secretary: Larry Dukerich (2014-2015)
    Larry Dukerich is serving the remainder of the term of Eric Brewe (Florida International University), who withdrew due to personal reasons. Larry received his B.S. in Chemistry from Michigan State University and his Masters of Natural Science from Arizona State University. He taught high school chemistry and physics, including regular, honors and AP courses, in Michigan and Arizona for 34 years. He is currently a Faculty Associate at Arizona State. Since 1995, he has conducted numerous Modeling Instruction summer workshops for physics and chemistry teachers at ASU, and later at sites in Pennsylvania, N. Carolina, Tennessee, Missouri and New York. He has also conducted chemistry workshops for the Ministry of Education in Singapore. He was a Woodrow Wilson Dreyfus Fellow in Chemistry in 1986 and a Presidential Awardee for Excellence in Science Teaching in 2000.
  • Treasurer: Lee Trampleasure (2014-2016)
    I am a high school teacher with 20 years of experience, the last
    seven years as a Modeler–primarily in physics but for the past two years
    also in a 9th grade physical science class. I attended two modeling
    workshop, Mechanics (2007) and CASTLE (2011), and in 2012 I assisted in
    running a Mechanics workshop at my school, bringing a Modeling workshop back
    to Northern California for the first time in many years. I also led several
    short introductory Modeling sessions at my local AAPT meetings, and serve as
    Section Rep at national meetings. In late 2011 I led the development of the
    new AMTA membership-based website, and have continued with maintenance and upgrades to the site. I look forward to the opportunity to serve as
    treasurer, and would bring with me six years of experience as a board member
    of a nonprofit foundation and ten years of small business experience.
  • Member-at-Large: Fernand Brunschwig (2012-2015)
    I was a faculty founder of SUNY Empire State College, now Emeritus after 40 years, edited and re-published Karplus’ Introductory Physics: A Modeling Approach in 2003, and am working on a free Web/E-Book version (at – Use “guest” as login and password). I am also interested in technology and have published physics simulations at <> (search on my name). I have been active in the NYC schools, and always wanted to do something to help physics teachers. In the spring of 2011, a group of physics teachers (most of them modelers) and I founded PhysicsTeachersNYC, which has organized popular weekend teacher-led workshops and summer Modeling Instruction Workshops at Columbia Teachers College. We now have over 190 members and are affiliated with the AMTA. As Member-at-Large and Chairman of PhysicsTeachersNYC, I pledge to do everything I can to strengthen and promote AMTA, to expand and upgrade teacher professional development, and to help modeling play the central role it deserves in the national effort to improve our schools.
  • Member-at-Large: Carlos Montero (2013-2016)
    My career as a teacher began in 2004 and after two ineffective years, I was blessed to encounter modeling.  As a chemical engineer, I could recognize effective scientific thinking but did not know how to impart it to others. My first workshop at Florida International University in 2006 revealed to me how exquisite teaching could be.  I was amazed at the pedagogical genius of modeling and adopted it wholeheartedly. Modeling saved my career as a teacher and has yielded exceptional results for students in my honors and AP chemistry classes.I have no doubt that modeling should be at the forefront of science education reform in this country.  That is why the role of AMTA is so precious.  The change can only happen through those teachers who have not only embraced modeling but have reached a high level of proficiency in it. I wish to be part of the AMTA board for two main reasons. First, I have incredible gratitude to what modeling has done for my career and the lives of my students; therefore, I wish to share the gift of modeling with everyone in the community. Second, I am optimistic about the future of science education and wish to be a part of its development. As a member of the AMTA board I will contribute my time and zeal for modeling to help support and expand our community. I am sure that our efforts will ultimately lead to the overall improvement of science literacy of our nation.
  • Member at Large: David Weaver (2014-2017)
    I spent 32 years teaching physics, electronics, semiconductors, etc. in the
    Maricopa Community College District before retiring in January, ’14 and
    attended two Remodeling University Physics summer workshops. I hired
    numerous Modelers as adjunct faculty at C-GCC. Periodically I have been
    active on Modeling listservs on a variety of topics. Over the last two
    decades, I’ve provided in-service professional development for K-8 teachers
    in the Phoenix area about physics content and inquiry science. I currently
    present workshops around the nation about Project-Based Physics. I have been
    teaching our two semester algebra-based physics courses online for the last
    5 years. I was recently invited to present at the AAPT special conference on
    Introductory Physics for the Life Sciences and will be attending the Gordon
    Research Conference on the same topic in June. I’m into tech stuff,
    computational physics (with Excel and VPython), etc.
