Overview With over 50 years of proven success, GrapeSEED English Language Acquisition is an English-only immersion program that taps into children's natural tendency to use language to communicate. The roots of the Natural Approach date back to the Committee of Twelve creation of the Modern Language Association in 1901 which describes the approach as series of "monologues by teacher" dotted with questions and exchanges with learners all in the foreign language [Krashen, S.D, Terrell, T.D., The Natural Approach. Prentice Hall, 1995,(10).]. A branch of this approach, the Audiolingual Method, expanded beginning in 1940s with the need for foreign language courses for military personnel [Ibid, (23).]. Research during 1990s contributing to the research-based design of GrapeSEED are reflected in the GrapeSEED design.
