One of twelve instructional units in the Native American Career Education (NACE) program, this unit is intended to help Indian junior high school students understand some of the principles which govern cultural change and to show how it is possible to adapt to change while retaining essential cultural elements. The five activities in the unit include reading, mapwork, games, and a community planning exercise to focus on differences and similarities in the ways in which basic needs are met at different periods in a culture's history and on the corresponding effects on lifestyles, roles, and careers within the culture. Related subject areas are history, geography, mathematics, transportation, and industry. Each activity includes objectives, student materials, and suggestions to the teacher on how to use them. Student exercises consist of readings, questions to answer, games, simulations, project instructions, and other learning activities. Each activity is followed by suggestions for ways of extending learning and, where appropriate, additional resources are described. Student materials may be used as master copies for reproduction or as models for material development. A test designed to measure student mastery of the main objectives is included with each unit, along with an answer key. (A guide for the whole twelve-unit program is also available--CE 014 035.) (TA)
