Gerald Feldman



Gerald Feldman, Co-Director, is a Professor in the Department of Physics where he teaches introductory physics courses and has dedicated 11+ years as the undergraduate advisor in physics. He has worked with physics majors who opted to pursue secondary school teaching based on their GW experience as lab teaching assistants and evening tutors. He is a co-principal investigator on an NSF S-STEM grant (2013-18) to provide scholarships for incoming students intending to pursue STEM careers. He was responsible for launching the active learning collaborative “studio style” pedagogy known as SCALE-UP at GW. He has extensive experience in STEM pedagogy and is active in physics education research at GW, nationally and internationally. Dr. Feldman teaches Research Methods in Mathematics and Science (GTCH 3202) in the GWTeach program of study.

Jonathon Grooms



Jonathon Grooms, Co-Director, has a background in chemistry and physics education that includes several years as a physical science instructor with students across the K-12 continuum. Building from his classroom experiences, his research and scholarship centers on how teachers support their students’ engagement with the essential practices of science and engineering and how teachers’ conceptions of disciplinary practices of science influence classroom decisions regarding student instruction. Dr. Grooms is currently examining the role of scientific argumentation as an instructional emphasis and how such classroom contexts support students’ development of science proficiency. This work is strongly aligned with current standards movements such as the Next Generation Science Standards and the Common Core State Standards in Mathematics and English Language Arts. Dr. Grooms teaches Knowing and Learning in Mathematics and Science (GTCH 3101) and Research Methods in Mathematics and Science (GTCH 3202). 

Meghan Hollibaugh Baker



Meghan Hollibaugh Baker is a Master Teacher for GWTeach. She studied at St. Lawrence University in NY where she earned a B.S. in Biology and minored in Education, earning teacher certification upon graduation in a model similar to the GWTeach program model. She was awarded a fellowship to complete her M.A. in General Education at St. Lawrence University, while co-teaching undergraduate education courses. She completed her Ed.D. in Educational Leadership at Johnson & Wales University in RI, with her research focused on the relationship between educational technology, student self-efficacy, and academic achievement.

Dr. Hollibaugh Baker has spent her teaching career working in urban school districts focused on closing achievement gaps and creating equitable opportunities for all students. She currently holds K-12 educator certifications in biology, general science, and building-level administration in DC, MD, NY and RI. Prior to joining the GWTeach team, Dr. Hollibaugh Baker taught high school biology, where she served in various leadership roles, before becoming an assistant principal at the middle school level. Dr. Hollibaugh Baker teaches Step 1+2 Hybrid (GTCH 2003), Classroom Interactions (GTCH 3102), Perspectives on Mathematics & Science (GTCH 3201W), Apprentice Teaching (GTCH 4000), and facilitates field experiences for GWTeach students.

Kamellia Keo



Kamellia Keo is an adjunct faculty member for GWTeach. She graduated from the University of Massachusetts - Amherst with a Bachelor of Science in Biology. She earned her Master of Science in Science Education from American University. Prior to joining the GWTeach team, Kamellia was a Mentor Teacher for the program for 7 years. She continues to work in DC Public Schools serving as a 7th and 8th grade science teacher as well as supporting other science teachers in the district through curriculum and professional development. Kamellia teaches Step 1+2 Hybrid (GTCH 2003).

Curtis Pyke



Curtis Pyke is an Associate Professor of Curriculum and Pedagogy in Math Education at the Graduate School of Education and Human Development. His role involves the development of math teachers through the Secondary Education M.Ed. He compliments that work by helping experienced teachers become education researchers through the Curriculum and Instruction Doctoral Program. He often collaborates with science education colleagues, math and science faculty, professional organizations and local schools, and has achieved national recognition for licensure programs, a master's-level curriculum for DC teachers, partnerships that provide tuition funding for teacher candidates and conducting major research in the curriculum materials field. Dr. Pyke became a teacher as an undergraduate through a program similar to GWTeach. Dr. Pyke teaches Classroom Interactions (GTCH 3102).

LaKeisha McClary



LaKeisha McClary is an Assistant Professor of Chemistry. At GWTeach, she is interested in research-based instructional strategies (RBIS) like problem-based learning and collaborating across disciplines with other faculty to develop new and better strategies for educating students in introductory-level science and mathematics courses. As a chemistry education researcher, she understands the challenges of integrating educational research into courses. She partners with multiple GW departments and with District of Columbia Public School teachers to develop strategies for success. By modeling quality, research-based instruction in actual college chemistry courses and allowing students to contribute to the sustainability of the instruction, she sees GWTeach as a way to transform students, faculty, administrative units and the communities where they live, work and play.

Tiffany-Rose Sikorski



Tiffany-Rose Sikorski is an Assistant Professor in secondary science education. Dr. Sikorski’s research explores how learners of all ages think, reason, and talk science. She specializes in analyzing “coherence seeking,” that is, learners’ collaborative efforts to build relationships between ideas and identify and reconcile inconsistencies. Her current work continues to expand the coherence seeking framework so that it can inform the design of assessments, curriculum, and learning progressions aimed at supporting scientific inquiry and disciplinary practices of science.

Dr. Sikorski's recently funded projects include the STEM Integration Project (Charles E. Smith Jewish Day School), the HARK Proof of Concept project (Honda Motor Company & Honda Research Institute Japan), Building Capacity for Disciplinary Experts in Math and Science Teaching (National Science Foundation), and The GW Learning Assistant Program (GW Columbian College of Arts and Sciences).

Dr. Sikorski's science teaching experience includes public and charter high schools, after school programs, and museum settings. Her pedagogy courses aim to empower future teachers to create meaningful science learning experiences for their students, experiences that build on students’ vast capabilities for making sense of the natural world and that sustain student interest and participation over time.

Dan Ullman



Dan Ullman is a Professor of Mathematics and Associate Dean of Undergraduate Studies. He served in 2006-2007 as the AAAS Congressional Fellow funded by the American Mathematical Society. During that year, he worked for the House Committee on Science and Technology, more specifically for their Subcommittee on Research and Science Education, focusing on math and science education policy at NSF. The critical shortage of well-prepared math and science teachers across the US became a central tenet of his work there, and his subcommittee set in motion a number of efforts to address this in the America Competes Act of 2007. Returning to GW, he became the PI of a Math Science Partnership, working on professional development of middle school math teachers in the District of Columbia. In association with that project, he visited many teachers and many schools across the District and saw first-hand what good teachers do and what bad teachers are unable to do. At the same time, he launched the D.C. Math Circle, through which he worked directly with groups of D.C. middle school students to introduce them to creative thinking and exploration of mathematics problems. For decades, our country has not done a good job of producing teachers who know math and science and also know how students learn math and science. His goal with regard to GWTeach is to be part of the national effort to turn this around—to train, motivate and mentor our brightest STEM students to enter the teaching profession.
