Mathematics

Algebra
Allan Gray

Algebraic concepts are presented in infinite detail, with patience and systematic review that teachers seldom have an opportunity to incorporate because of the countless distractions and interruptions they face. Available to faster and slower students alike, for review, makeup, and acceleration. Content includes all of what would be First Year Algebra for most schools.

Basic Calculus
Lloyd Williams, Ph.D., Reed College

A course for a student who has had two years of Algebra, a semester of Trigonometry with logarithms, and who knows how to use graphs. This course will prepare the student for a freshman college course in Physics or Engineering in which Calculus is used. Equivalent to a one-semester college course in Differential and Integral Calculus, and is a preparation for an honors course in Theoretical Calculus.

The concepts of limit, derivative, & integral are explained without formal proofs but with extensive graphical interpretation. Explanatory comments are made about all problems, & many are solved in detail. Symbols & notations are carefully explained.

Constructional Geometry
Brunelle / O'Neill

This course provides background in Geometry, acquaints students with geometrical terms, and teaches how to solve simple problems involving geometry or geometrical figures. It stresses doing, by having students work mainly with the ruler, compass, and protractor. There is also some review of basic numerical calculations, such as proportions, square roots, etc.

General Mathematics
Gray / Matousek

A very thorough review of basic math principles — starting with single-column addition and progressing through fractions and decimals. Extensive testing for convenient determination of need and accomplishment.

Problem Solving Arts - An Alternative to Mathematics
Norman Crowhurst, Ph.D.

Part 1 This phase of learning to solve problems is described as “developing simple tools to work with.” It runs through the four basic functions, use of various measurement units (including metric), negative numbers, approximations and decimals, percentages, early geometrical problems, and graphing.

Part 2 explores progressively easier and faster ways to solve successively harder problems. It covers algebra as a simplifier, up through simultaneous and quadratic equations, finding ways to check validity and accuracy, understanding irrational quantities, powers, roots, more geometry, applied to short-cuts in calculating and problem-solving, with a practical approach to imaginary and complex numbers.

Part 3 covers ways to use mathematics on itself, to make calculating and problem-solving easier, up through introductions to differential and integral Calculus, and discussions of coordinate systems, MacLaurin’s Series, conic sections, Fourier Series, computer applications, and many other practical considerations.

Introductory Statistics
Norman Crowhurst, Ph.D.

Statistics is a subject of growing importance in many fields, and has become a required subject in many Schools of Education and Business Administration, as well as Junior and Community Colleges. Because the subject is often little understood, wrongly applied, or in the wrong context, this new course has been designed to correct that deficiency, so its graduates can move freely through the “mystical” realms of statistics with assurance that they can apply established principles appropriately.

Numerical Trigonometry
Bryson / Gray

The development leading to the principal ideas of the course is unique for this level of study. The Introduction to Trigonometric ratios is made through a study of the standard position angle and coordinates on the plane. A student is led to think of Trigonometric ratios first as properties of general angles; then from these properties, the specific relationships for right triangle Trigonometry are obtained with an easy-to-follow style. The climax of the course is the application of Trigonometric ratios to the solution of the four cases of the oblique triangle.

Taking the Mysticism from Mathematics
Norman Crowhurst, Ph.D.

This book was originally prepared, during the 60s, to show why a large proportion of our population has hangups about math, and to enable such people to overcome their individual hangups, to become proficient and interested in math. It has done that and far more, for it provides the foundation for a problem-solving, systems-design approach to a far greater variety of subjects, that can aid in solving many of our nation’s problems today.
