Answer:
The period of American colonialization of the Philippines lasted 48 years, from cession of the Philippines to the U.S. by Spain in 1898 to U.S. recognition of Philippine independence in 1946. ... During that war, Philippine revolutionaries declared independence.
One such policy was the introduction of the American system of education, and so pervasive and far-reaching was its impact and influence on the life and culture of the Filipino during and after the colonial period that it is generally regarded as the "greatest contribution" of American colonialism in the Philippines.
Volunteer American soldiers became the first teachers of the Filipinos. Part of their mission was to build classrooms in every place where they were assigned. The American soldiers stopped teaching only when a group of teachers from the U.S. came to the Philippines in June 1901.
