Nina Barcelli, Science Curriculum Designer

Washington, DC 20001

Nina Barcelli is a Teach for America alum who worked as a middle school science teacher in the Washington, DC area for eight years. In 2013 she connected with a group of volunteers from the NIH to form an extracurricular science program at the school where she taught, Center City Public Charter Schools’ Shaw Campus. From there, the Saturday science club called Curiologie in the Classroom was born, but it was not until a partnership with RESET in 2014 that the program reached its full potential. Mrs. Barcelli credits RESET with taking Curiologie to the next level, providing resources for everything from lesson planning to field trips, and establishing an overall structure that could support dozens of participating students long-term. Because of her demonstrated dedication to her students and commitment to the success of Curiologie in the Classroom, Mrs. Barcelli was honored as RESET’s Teacher of the Year for the 2017-2018 school year.

Since making the difficult decision to change career paths in the summer of 2018, Mrs. Barcelli has worked as a Learning Design Editor for the science curriculum team at Great Minds, assisting in the development of a highly anticipated national science curriculum aligned to the Next Generation Science Standards. As a new Board member, Mrs. Barcelli is looking forward to lending her expertise in science curriculum development and is most excited about interacting with students again.

Shelia Tobias, Author and Educator

Tucson, AZ

Sheila Tobias has made an art and a science of being an outsider to science and mathematics, where hers is a household name for the books, Overcoming Math Anxiety, They’re not Dumb, They’re Different, Breaking the Science Barrier, and Rethinking Science as a Career.
She has just co-authored a new book, Banishing Math Anxiety. Ms. Tobias is equally well known in academic and popular circles as a feminist and for her books, Women, Militarism and War (with Jean Elshtain) and Faces of Feminism: An Activist’s Reflections on the Women’s Movement.

Supported by the Ford Foundation, Rockefeller Foundation, Research Corporation, and the Alfred P. Sloan Foundation, her work has made her a sought-after consultant on college and university curricula, general education, post-baccalaureate alternatives, professional master’s in science and mathematics, and women’s studies.

Ms. Tobias chose to join RESET because it corresponds to her twin agendas: giving girls a head start in dealing with the social stigmas they may still encounter being interested in math/computers, and providing researchers like herself with models as to what interventions work.

Educated in history and literature at Harvard/Radcliffe, Ms. Tobias earned a master’s in history and an M. Phil at Columbia University and eight honorary doctorates, the most recent from Michigan State University and Worcester Polytechnic Institute.
