These three self-contained home economics miniunits on consumer behavior are part of a set of 21 designed to provide middle school/junior high boys and girls opportunities to explore several areas of study within a 6-, 9-, or 12-week period of instruction. Units are designed to be free of sex-role stereotyping and are identified as level I (suggested for grades 6-7) or level II (suggested for grades 8-9). The suggested time required for completion of a unit varies from 3 to 9 weeks, those incorporating laboratory experience requiring 6 to 9 weeks. Titles and levels of these three units are: Consumer Decision Making (level II); Dealing with Dollars (level II); and Metric Mind (level I or II). Each unit is composed of: (1) an introductory page that includes a brief description of the focus of the unit, a statement of rationale and objectives, and suggested grade level and time for completion; (2) the body of the unit composed of conceptual content (statements which identify the concepts and generalizations relevant to the objectives) and the suggested learning approach, and (3) support material, which identifies by number and page the suggested materials to be used in pupil-teacher interaction (Some materials are included; some are to be secured from the source identified at the end of the unit). A brief synopsis of all 21 miniunits plus descriptions of the development and field testing of the units are included. (HD)
