This book deals with teaching mathematics to children during the years of three to nine. According to the author, the book espouses "the pedagogical principle that the child ought to have some idea of what is going on." The content of the book is divided into eleven chapters: (1) An Introduction, (2) Counting, (3) Measurement and Quantitative…

This document is the report of a conference attended by an international group of specialists in mathematics and learning. It was convened by the United Nations Educational, Scientific, and Cultural Organization Institute for Education. The general objective of the conference was to examine problems concerning mathematics reform in the primary…

The materials in this bulletin consist of a series of daily lesson plans for use by teachers in presenting a modern program of seventh year mathematics. In these lesson plans are developed concepts, skills , and applications. There is an emphasis on (1) an understanding of mathematical structure, (2) growth of a number system, (3) relations and…

The only way to see what is different about the new ways of doing mathematics is to study some new mathematics presented in a new way. This small text is designed for parents to enable them to study some of the new mathematics topics. The two chapters which are included are extracted from a seventh grade SMSG text. Interspersed throughout are…

The purpose of this study was to investigate the effects on achievement and attitude resulting from the use of a calculator-based curriculum and a classroom set of hand-held calculators in ninth-grade general mathematics. Six teachers participated in the study, each having one class in the calculator treatment and one class in the non-calculator…

The objective of the study was to determine the effect which a unit dealing with recursive definitions would have on students' achievement in applying the principle of mathematical induction (PMI). Twenty-four secondary school students were randomly assigned to control and experimental groups. Students in the control group studied programmed units…

The developmental unit, intended to become part of a total K-12 career education curriculum, is designed for use at the kindergarten level. The overall purpose is to promote in the learner an understanding that the three basic skills he is acquiring in school are relevant to those required in everyday life. The unit provides approximately 10 hours…

Studies concerned with the synchronous emergence prediction of Piaget's structures-of-the-whole principle are discussed in conjunction with three groups of concrete-operational skills: (1) transitivity/conservation/class inclusion; (2) double classification/double seriation; and (3) ordinal, cardinal, and natural number concepts. Findings show…

A two-phase study was designed to investigate the relationship between cognitive skills hypothesized (by Piaget) to underlie number competence, and performance on tasks requiring logical reasoning with number-related concepts. During the first phase, a battery of tasks was administered to 60 kindergarten and 60 third-grade students. These tasks…

This booklet consists of 11 bulletins designed to answer questions which teachers frequently ask about the learning and teaching of mathematics. (The bulletins are revisions of a set originally published in 1970.) Each bulletin is organized around a central topic, and presents questions related to that topic, summaries of research findings…

This booklet, developed by the Oregon Vo-Tech Math Project, contains a broad range of mathematical problems used related to vocations in the area of marketing. Solutions to all problems are included. Problems included involve whole numbers, fractions, decimals, measurement, solution of equations, logarithms, and percent. (SD)

This is one of eighteen sets of individualized mathematics problems developed by the Oregon Vo-Tech Math Project. Each of these problem packages is organized around a mathematical topic and contains problems related to diverse vocations. Solutions are provided for all problems. This volume contains problems involving ratio and proportion. Some…

This is one of eighteen sets of individualized mathematics problems developed by the Oregon Vo-Tech Math Project. Each of these problem packages is organized around a mathematical topic and contains problems related to diverse vocations. Solutions are provided for all problems. Problems in this volume require the computation of square roots,…

This paper proposes a method for teaching number applying the conservation theory of Piaget in the classroom. It is suggested that number facts cannot be taught by social transmission, since there is a fundamental distinction between logico-mathematical and social knowledge. Conservation cannot be taught to non-conservers, but there are ways to…

The "modern mathematics" curriculum places considerably more emphasis on the use of precise terminology when referring to properties of whole numbers than did previous curricula. The relationship between the ability to make these verbal associations and other aspects of mathematics achievement of sixth graders is investigated in this study A…
