circa 1924: INTERNATIONAL RECOGNITION

Poster text:

Every summer, in response to invitations from governments or educational associations, Helen Parkhurst goes abroad to lecture and to help to establish schools.

The Laboratory Plan is particularly successful in Holland and in England where a Dalton Association is formed and several schools adopt the Dalton method. Miss Parkhurst, Miss Keefe Durham and other members of the staff, travel to Korea, China and Japan. A few years later, Miss Keefe Durham spends half a year in Chile, where she supervises the establishment of a Dalton School and trains teachers to operate it.
