Designed for current and future occupational instructors, counselors, and administrators, the comprehensive measurement text is directed toward all subject areas in occupational education--industrial, business/distributive, home economics, agriculture, health occupations, and personal/public services. It offers necessary guidelines to select, develop, apply, and evaluate teacher-made and standardized vocational education tests. Part 1 focuses on reasons for using measurement procedures and techniques, types of instruments, and some concepts essential to a broad understanding of the area of study. Specific measurement concepts examined include: validity, reliability, measurement error, scales of measurement, point of reference for measurement, and role of measurement. Part 2 contains in-depth chapters on: Basic Considerations for Teacher-made Tests, Planning the Test, Constructing Measures of Cognitive Achievement, Constructing Measures of Performance, Constructing Measures of Affect, Assembling the Teacher-made Instrument, and Evaluating Teacher-made Instruments. Part 3 discusses the use of standardized instruments in vocational programs. The concluding section covers the administration of teacher-made/standardized instruments; scoring, reporting, and interpreting test results; and the use of measurement data and information in occupational programs.
