Choices for the 21st Century Education Program has made available several volumes of curriculum on the iTunes store, making it the first higher-education content to be included there. The volumes available for purchase span a wide range of topics including the Cuban Missile Crisis, the Russian Revolution, the United Nations, and the history of the slave trade in New England and are designed to be used in conjunction with printed materials available on the Choices website. The Choices program is an educational outreach program of the Watson Institute for International Studies at Brown University. Through its curricular resources, professional development programs, and special projects, Choices reaches high school students and teachers in more than one-third of American high schools.
