DESCRIPTCES *Blueprints; *Curriculum;.Instructional Materials; learning Activities; Measurement Instruments;*Metric System; Secondary Education; TeachingTechniques; *Trade and Industrial Education; Units f Study (Subject Fields) ;Vocational Education ABSTRACT Desdgned to meet the job-related metric measurement needs of blueprint reading students, thisinstructional package is one of eight for the manufacturingoccupations cluster, part of a set of 55 packages for metric instruction indifferent occupations. The package is intended for students who already knowthe owcupational terminology, measurement terms, and tools currentlyin use. Each of . the five units in this.instructionll packagecontainsperformance objectives, learning activities, andsupporting'information in the fort of text, exercises, and tables. Inaddition, suggested teaching techniques are itcluded. At the back of the package are objective-based evaluation items, a page of answers tothe exercises and tests, a list of metric materials neededfor the activities, references, and' a list suppliers. The material is designed to c,Qcompodate a variety of individual teaching andlearning styles, e.g., independent study, small group, orwhole-class activity. Exercises are intended to faciiitate experienceswith measurement instrutents, tools, and devices used in this occupationand job-related tasks of estimating and measuring.Unit I,-a general intxoduction to the metric system of measurement,provides informal, hands-on experiences for the students. This unit enablesstudents to become familiar with the basic metric units, theirsymbols, and measurement instruments; encl.-todevelop a set of mental references for metric values. The metric system of notationalso is explained. Unit 2 provides the metric terms which are used inthis occupation and gives experience with occupationalmeasurement.tasks. Unit 3 focuses on jot-related metric equivalents andtheir relationships. Unit 4 provides experience with ecognizing and using metric instruments and tools in occupational measurementtasks. It also provides experier,ce in comparing metric and customarymeasurement instruments. U- is designed to give students practice in converting ous- y and metric measurements, askill considered useful during tiransition to metric in each occupation.
