Excerpt from Teacher's Manual for First Year Algebra Scales The First Year Algebra Scales were first published in 1918. Since then they have been extensively used by teachers, school administrators, directors of educational research, and in various school surveys. 1. Description of Scales The scales consist of five different sheets of algebraic exercises designed to measure the ability of pupils in elementary algebra. They are: 1. Addition and Subtraction 2. Multiplication and Division 3. Equation and Formula 4. Graphs 5. Problems The first two scales, it will be seen, are designed to test the achievement of students in the fundamental operations, involving integral, fractional, and radical expressions; the second two, to test the ability of students in handling the instruments of quantitative thinking; while the last is composed of verbal problems of the type usually stressed in the first year of algebra. The exercises in each scale are arranged in order of difficulty; that is, each scale begins with exercises so easy that they can be solved by practically every member of a class. Each succeeding exercise, however, becomes increasingly more difficult so that the last ones in each scale can be solved by only a relatively small number of students who try them. Two series of each scale are offered - Series A and Series B. Series B is the longer and contains from eleven to twenty-five exercises in each scale. Series A is only about one half as long and contains from eight to twelve exercises in each scale. It covers just as wide a range of difficulty and has the added advantage of having the intervals between successive exercises and problems approximately equal: that is, Ex. 3 of a given scale is as much more difficult than Ex. 2, as Ex. 2 is more difficult than Ex. 1.
