"Technology and Changing Lifestyles" is one of the "Preparing for Tomorrow's World" (PTW) program modules. PTW is an interdisciplinary, future-oriented program incorporating information from the sciences and social sciences and addressing societal concerns which interface science/technology/society. The program promotes responsible citizenry with increased abilities in critical thinking, problem-solving, social/ethical reasoning, and decision-making. This module introduces students (grades 7-8) to the concept of change as reflected in changing lifestyles. Subject matter is presented in three sections, examining: family roles in earlier Amerindian society (low technology) and society today (high technology); role/purpose of education by comparing/contrasting the two cultures; and how lifestyle needs impact on land, its resources, and other people. The teaching guide includes an overview of the module (purpose; strategies employed, focusing on the dilemma/debate discussion technique; module structure/objectives; and its use in the school curriculum) and instructional strategies related to the readings, dilemma disucssions, and student activities in each of the three sections. A chart indicating moral issues (as defined by Kohlberg) presented in the dilemmas and list of suggested readings are also included. The module may be used as a separate unit of study, mini-course, or incorporated into social studies, language arts, history, or general science courses. (JN)
