Ms. Graciela Quiroga

Assistant Vice Principal, Middle School Advisor, Professional Development Advisor

Graciela Quiroga is from Buenos Aires, Argentina and she has been teaching for more than three decades. She started her career as a First, Seventh and Eighth Grade teacher. Once in the U.S., she joined Washington International School (WIS), W.D.C. in 1989, where she taught First Grade for three years. Thereafter, she moved to Middle School as a Language-Literature and Spanish Humanities-World History teacher.

Mrs. Quiroga has participated in various educational seminars across the U.S., as well as abroad. For example: Georgetown University-Center for Latin American Studies; National Gallery of Art, Understanding by design, Art Connection; Project Zero- Harvard, Graduate School of Education, and iEARN International Conference, Slovakia. She has presented workshops in the area including the International Baccalaureate conference at The Hague (Perspectives in the Teaching of History).

Mrs. Quiroga received her Project Zero (PZ) Certification in 2010 from the Harvard Graduate School of Education. This was a turning point in her educational career, which led her to a continued revision of teaching and learning from a Teacher for Understanding (TfU) perspective. Since then, the focus of her teaching has been to facilitate student’s ongoing opportunities to foster their understanding and awareness of their own thinking and learning process.

Guided by her classroom’s core value of social justice, she firmly believes that educators should prepare students to become responsible citizens for the XXI Century.  Along with this principle, she has been working towards the development of multi and interdisciplinary projects to encourage young learners to reflect on global issues.

One of her most successful accomplishments has been the Student Exchange Program, which was initiated at WIS with Mrs. Viviana Cruz in 1997. Since then, Mrs. Quiroga has been the coordinator of the cultural activities for all the trips to Mexico, Uruguay, Lima and Madrid, in tight connection with the Language and Humanities Curriculum.

Her two years at Bethesda International School, (BIS-CIB), Maryland, as an Upper School Language-Literature teacher was another enriching experience that further developed her research initiatives of PZ. In August 2017, she joined BIS-CIB as a Resource Teacher and Middle School Curriculum Coordinator. Mrs. Quiroga is enthusiastic to continue implementing Teacher for Understanding-TfU- as a conceptual framework to cultivate student’s deep understanding.

Mrs. Quiroga has a Bachelor’s Degree in Education and an Associate’s Degree in Language Arts from Sarmiento National College in Buenos Aires. She graduated with a degree in Sociology from the National University of Philosophy (Universidad Nacional de Filosofía y Letras) in Buenos Aires, Argentina.
