An experimental test battery (the Johnson O'Connor Research Foundation battery) designed to measure numerical facility was administered to 1,451 subjects at 12 testing centers across the United States over a 5-month period. Five work samples were included: (1) arithmetic; (2) counting backwards; (3) number reasoning; (4) rule learning; and (5)…

As part of a curriculum development project for gifted students, seventh and tenth grades (N=323) were tested with the Structure of Intellect Learning Abilities Test (SOI-LA) to compare students' scores with norms already collected, investigate differences between the sexes, identify specific types of tasks to promote achievement, and to determine…

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…

This is a supplementary unit to Mathematics for High School, Intermediate Mathematics, Part 1. In this publication, real numbers and rules for operating them are examined. The study begins by examining whole numbers and some of the properties of addition and multiplication of whole numbers. Most of the basic rules for algebra are developed from…

This unit is designed for elementary school students in intermediate grades. It is designed to make mathematics enjoyable, promote systematic thinking, practice and reinforce arithmetic skills, and provide opportunity for independent research. The student manual contains twelve lessons with background information and activities. In addition, the…

The factor-analytic history of the isolation and identification of the cognitive ability construct known as Number or Numerical Facility is described. Empirical documentation from the psychometric literature is discussed, and examples of items from a variety of tests which have defined and been associated with the Number factor are included to…

This textbook is an illustrated table book rather than an elementary arithmetic book. Its object is to suggest things for pupils to do. While it is impossible in a work so small to do more than give suggestions, the teacher will find little difficulty in supplying the deficiency by the use of the blackboard. Although there is nothing in the book…

Developed by the Initial Learning in Mainstreaming Project, the manual presents an instructional program to teach mainstreamed handicapped elementary school students how to do long division to remainders. In addition to detailed teaching instructions and text of tape recordings for students, the manual includes tests, worksheets, and pages to be…

Developed by the Initial Learning in Mainstreaming Project, the manual presents an instructional program to teach mainstreamed handicapped elementary school students how to tell and compute time in terms of hours, minutes, and seconds. In addition to the basic time facts, the lessons cover carrying or borrowing with off-base-10 time facts, and…

Developed by the Initial Learning in Mainstreaming Project, the manual presents an instructional program to teach mainstreamed handicapped elementary school students the carrying process (regrouping) for addition. In addition to detailed teaching instructions and text of tape recordings for students, the manual includes tests, worksheets, and…
