This series of seven booklets is designed to train teachers of adults in metrication, as a prerequisite to offering metrics in adult basic education and general educational development programs. The seven booklets provide a guide representing an integration of metric teaching methods and metric materials to place the adult in an active learning environment, with learning activities arranged to help the adult learn metrics by actually using metric measures. The first section of booklet 1 contains a general introduction to the series and to metrics instruction; the second contains guidelines for conducting inservice sessions on metrication; the third section is an evaluation of selected metric equipment. Booklets 2-7 each contain from one to four units of instruction for teacher inservice sessions. Unit contents include objectives, teaching strategies, teaching evaluation, sample written exercises, and lists of resources. The units in their respective booklets are as follows: Booklet 2--understanding the need for metrics, understanding calibration, the decimal system, and understanding prefixes; booklet 3--measuring length, and determining area; booklet 4--measuring volume; booklet 5--measuring weight; booklet 6--determining temperature; and booklet 7--conversion between metric units. (Although the series could be used by adult educators for self-study, the authors recommend that it accompany inservice sessions led by trained metric educators.) (MF)
