A set of 20 learning modules in early U.S. history for students of English as a Second Language are presented. They are intended for use in alternative classes for limited-English-speakers or in mainstream U.S. history classes as individualized assignments, to give students a basic foundation in U.S. history, introduce them to some of the reading and thinking skills needed to understand social studies materials, and reinforce the English instruction the students are getting elsewhere. Units cover pre-Columbian history, discovery and exploration, the colonial period, and the American Revolution. The content and language have been simplified. Each unit contains a vocabulary section, a short reading, history activities, language activities, and a key to the activities. The vocabulary section includes a word list, definitions, and sentences illustrating word-usage and previewing the reading. Maps and illustrations are provided. (MSE)
