Many home economics teachers have experienced difficulty in developing good classroom tests and have expressed a need for help. This publication was prepared to provide guidance in the construction and use of a variety of measurement devices. Section 1 discusses the role of measurement in the instructional process including why measure, what to measure, and how to measure. Section 2 deals with preparing instruments used to assign grades. Advice is given on preparing a test blueprint, choosing an item type (essay, completion, true-false, multiple-choice, and matching), and measuring cognitive and psychomotor learning outcomes. Section 3 discusses preparing instruments used to evaluate and plan instruction related to cognitive, psychomotor, and affective learning outcomes. (RC)
