This competency-based preservice home economics teacher education module on children's center aide is the second in a set of four modules on establishing occupational programs in human development. (This set is part of a larger set 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) preparation for observing in a day care facility (with a lesson involving listening to tapes), (2) volunteering and working with a day care aide, and (3) preparing a presentation of your work experience. Each unit includes objectives and an overview. Lessons contain narrative summaries and suggested activities. A list of suggested resources is included in this module. 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 the home economics instructional programs [CE 019 900].)
