MATHEMATICS CLUSTERS IN SELECTED AREAS OF VOCATIONAL EDUCATION, REPORT NUMBER 8.

IDENTIFICATIONS WERE MADE OF THE MATHEMATICAL KNOWLEDGES COMMONLY USED IN OCCUPATIONS MOST READILY SUITABLE FOR NONCOLLEGE-BOUND YOUTH. TASK ITEMS FROM QUESTIONNAIRES USED IN OFFICE OCCUPATIONS, GENERAL MERCHANDISING, BUILDING TRADES, ELECTRONICS, FOOD SERVICE, CHILD CARE, AND AGRICULTURE STUDIES WERE EXAMINED FOR MATHEMATICAL KNOWLEDGE CONTENT. FIVE CLUSTERS OF MATHEMATICS KNOWLEDGES WERE FOUND TO BE USEFUL IN ALL THE JOB AREAS STUDIED. THESE CLUSTERS WERE (1) OPERATIONS WITH FRACTIONS, (2) OPERATIONS WITH DECIMALS, (3) CONVERSION OF FRACTIONS TO DECIMALS, (4) CONCEPT OF PERCENTAGE, AND (5) RATIO AND PROPORTION. STUDY RESULTS WERE CONSIDERED TENTATIVE. THIS VOLUME REPRESENTS PART 8 OF THE 13-PART FINAL REPORT ON THE VOCATIONAL-TECHNICAL EDUCATION RESEARCH AND DEVELOPMENT PROJECT OF WASHINGTON STATE UNIVERSITY.
