Eleanor Ruth Duckworth (born 1935) is a teacher, teacher educator, and psychologist.
Duckworth earned her Ph.D. (Docteur en sciences de l'éducation) at the Université de Genève in 1977. She grounds her work in Jean Piaget and Bärbel Inhelder's insights into the nature and development of understanding and intelligence and in their clinical interview method. Duckworth also has been an elementary school teacher. Her participation in the 1960s curriculum development projects Elementary Science Study and African Primary Science Program was germinal for her insights and practices in exploratory methods in teaching and learning. She has conducted teacher education, curriculum development, and program evaluation in the United States, Europe, Latin America, Africa, Asia and her native Canada. Duckworth is also a coordinator of Cambridge United for Justice with Peace and a performing modern dancer.

Short biography
Duckworth is the daughter of Jack and Muriel Duckworth, Canadian peace workers and social and community activists. She is named after Eleanor Roosevelt. Jack Duckworth, born in 1897, was a highly regarded leader in the national YMCA movement and an outspoken pacifist from the 1930s until his death in 1975. Muriel Duckworth, born in 1908 (maiden name Ball), who celebrated her hundredth birthday on October 31, 2008, was renowned as a crusader for social justice, women's rights, de-militarization, educational development and fighting poverty. She was one of the 1000 women worldwide nominated for the Nobel Peace Prize in 2005.

Duckworth studied ballet in Halifax, Nova Scotia, as a student of Irene Apinee and Jury Gotshalks, and danced in the Gotshalks Halifax Ballet. She stopped her dance studies at the age of 15, and started again at the age of 58.

She is the sister of Montreal filmmaker Martin Duckworth, and Nova Scotia businessman and musician John Duckworth.
(Re-)discovering Piaget
Piaget first influenced the child study and progressive education movement in Europe with publications such as (1923) and (1924), translated into English in the 1920s, and his experiments showing how young children understand size and volume were exhibited in the London Science Museum in the 1950s. However, Piaget's work was little known in the North American educational community after World War II until Eleanor Duckworth, a student of Piaget at that time, introduced his methods and analysis into the classroom and the US educational research community.
Eleanor Duckworth first met Jean Piaget in 1957 in Paris at the Sorbonne where she was a graduate student. For the next two years Duckworth studied with Jean Piaget and Bärbel Inhelder at the Institut des Sciences de l'Education in Geneva, Switzerland. She served as a research and teaching assistant for the second of those years. She subsequently entered a doctoral program in cognitive psychology at Harvard University, and dropped out. For the years to come, the work with Piaget and Inhelder would have an important impact on her thinking and further development. She returned to Geneva to finish her doctorate.
At Inhelder's recommendation, Duckworth began to participate in the Elementary Science Study (ESS) in 1962, a curriculum development and science education reform project that grew out of MIT and became the foundation of the organization now known as Education Development Center. The project was initiated by Jerrold Zacharias and participating scientists and teachers included, among others, David Hawkins, Mike Savage, Philip Morrison, Phylis Morrison, Ben Nichols, Claryce Evans, Lynn Margulis, Marion Walter, David Webster, Ed Prenowitz, Mike Rice, Cap Weston, Elsa Dorfman, and Edith Churchill. The project involved "[putting] physical materials into children's hands from the start and help[ing] each child investigate through these materials the nature of the world around him [stet]" (ESS, 1970, p. 7). Teachers and students experimented with natural materials like bulbs, batteries, pendulums or butterflies, ice cubes and earthworms. During her four years as a staff member at the ESS, Duckworth struggled to incorporate the theory and clinical method of Piaget into the work she and her colleagues did in classrooms (Duckworth, 2006, p. 1).
