The goal of this study was to develop a framework for classifying algebra story problems and to determine observed frequencies for each problem type. One thousand ninety-seven algebra story problems were selected from nine standard algebra textbooks. These are divided into eight families based on the nature of the source formula involved; for…

Ten review lessons in basic mathematics are presented in this workbook designed for electrical apprentices and vocational students. The lesson topics are numbers (whole, positive, negative), fractions, decimal fractions, finding common denominators, reciprocals, percentage, powers and square roots, ratio and proportion, the circle and its use of…

This is a teacher's manual for an ISS-based elementary school course in the metric system. Behavioral objectives and student activities are included. The topics covered include: (1) linear measurement; (2) metric-decimal relationships; (3) metric conversions; (4) geometry; (5) scale drawings; and (6) capacity. This is the first of a two-part…

This is the second part of a two-part teacher's manual for an ISS-based elementary school course in the metric system. Behavioral objectives and student activities are included. Topics include: (1) capacity; (2) calculation of volume and surface area of cylinders and cones; (3) mass; (4) temperature; and (5) metric conversions. (BB)

Thirty-six lessons for introducing the metric system are outlined. Appropriate grade level is not specified. The metric lessons suggested include 13 lessons on length, 7 lessons on mass, 11 lessons on capacity, and 5 lessons on temperature. Each lesson includes a list of needed materials, a statement of the lesson purpose, and suggested…

The Fry Graph for Estimating Readability (Extended) and George Magginnis' formula for passages shorter than 100 words were used in an investigation of the reading levels of 18 mathematics textbooks produced for grades one through six by three major publishers. The results indicated that the readability levels of the textbooks were inaccurate. Few…

This guide is to assist teachers with motivational ideas for teaching elementary school mathematics. The items included are a wide variety of games (paper and pencil, verbal, and physical), jingles, contests, teaching devices, and thought provoking exercises. Suggestions for selection of mathematical games are offered. The devices are used to…

This study examines the effect upon comprehension, as measured by cloze scores, of material in mathematics that is rewritten on the basis of elementary and junior high school subjects' oral language patterns. Syntactic structures were identified which appeared to inhibit or facilitate comprehension for the subjects involved. The mean number of…

This guide is the sixth in a series of publications to assist teachers in using a laboratory approach to mathematics. Twenty activities on probability and statistics for the elementary grades are described in terms of purpose, materials needed, and procedures to be used. Objectives of these activities include basic probability concepts; gathering,…

The processes by which statistical software is produced and made available to users were the main concerns of the conference. Six major topics were considered in relation to these software programs which perform the basic mathematical computations required in science and engineering: 1) the quality of mathematical software; 2) education and…

Four new Project SOLO modules are presented here: Langragian Interpolation/Extrapolition, Optics, Chemistry (Laboratory Style), Chemistry (Boy/Girl Style). The latter program is a computer dating system which proved to be very popular with the high school students who developed it. (JY)

PSYCHOLOGICAL PRINCIPLES INVOLVED WITH RULE GENERALITY (DEGREE OF NONSPECIFICITY) AND PERFORMANCE CONSISTENCY IN MATHEMATICAL PRESENTATIONS WERE STUDIED. SPECIFICALLY, THE PURPOSES WERE (1) TO DETERMINE IF TEST BEHAVIOR CONFORMS TO THE SCOPE OF A VERBALLY ADMINISTERED TEST RULE, (2) TO EXPLORE THE INTERPRETABILITY OF VERBAL TEST RULES, AND (3) TO…

The authors present a teaching module designed to allow students to convert fractions to decimals using any four function calculator, do the prime factorization of the denominator with the calculator, and find patterns formed by the denominators of the fractions that are terminating decimals. (MN)

This is the fourth installment of a "teach yourself" style workbook about simple four function calculators and elementary concepts in computer programing. This installment introduces mixed operations. (MN)

A manipulative model for the addition, subtraction, and multiplication of integers is described in which a carpet square with a hole in it and the plug that fits in the hole are "opposites" of each other. Several other models for integer multiplication are briefly described. (MN)
