This competency-based preservice home economics teacher education module on societal changes affecting the consumer habits of individual living units is the first in a set of five modules on consumer education related to human development. (This set is part of a larger series of sixty-seven modules on the Management Approach to Teaching Consumer and Homemaking Education [MATCHE]--see CE 019 901-967.) Following the module objectives and overview, three units of instruction are presented: (1) current changes in society affecting families and other living units (includes lessons on the process for uncovering affectual changes and a selected issue for study); (2) projecting the effect of societal changes on consumer habits of living groups (includes lessons on testing a hypothesis through interview and validating study by reviewing research); and (3) creating and influencing secondary curriculum to reflect changing consumer habits resulting from changes in societal patterns (includes a lesson on planning a teaching module). Each unit includes the unit objectives and overview. Each lesson includes a narrative summary and suggested activities. A module pre/posttest (with answer key) concludes the document. (Workshop proceedings relating to the development of these modules are available in the ERIC system as CE 019 896-899; also available is a module on utilizing FHA-HERO as an instructional strategy to expand and strengthen home economics instructional programs [CE 019 900].)
