This is the third part of a three-part SMSG algebra text for high school students. Chapter titles include: Truth Sets of Open Sentences; Graphs of Open Sentences in Two Variables; Systems of Equations and Inequalities; Quadratic Polynomials; and Functions. (MK)

Marital adjustment over the family life cycle is reexamined using data from probability samples of married couples studied in coordinated research projects in three different states--Iowa, Ohio, and Georgia. A total of 1,584 respondents completed the Locke-Wallace Marital Adjustment Scale and responded to questions about stage of the family life…

GRADES OR AGES: Grade 9 and 10 (first and second courses). SUBJECT MATTER: Algebra. ORGANIZATION AND PHYSICAL APPEARANCE: The material for each grade is presented in four columns: major areas, significant anticipated outcomes, observations and suggestion, and references and films. The topics covered in the first course include reviews of set…

Unit 10 in the SMSG's secondary school mathematics series is a student text covering the following topics in Algebra I: factors and exponents, radicals, polynomial and rational expressions, truth sets of open sentences, graphs of open sentences in two variables, systems of equations and inequalities, quadratic polynomials, and functions. (DT)

This study examines the implementation of a problem-based math curriculum that uses problem situations related to global warming and pollution to involve students in modeling polynomial, exponential, and logarithmic functions. Each instructional module includes activities that engage students in investigating current social justice and…

The author presents a technique for solving limit problems that involve polynomial or rational functions by using delta, epsilon proofs. (MN)

Nonlinear common factor models with polynomial regression functions, including interaction terms, are fitted by simultaneously estimating the factor loadings and common factor scores, using maximum likelihood and least squares methods. A Monte Carlo study gives support to a conjecture about the form of the distribution of the likelihood ratio…

The title describes two challenges with which mathematics teachers nowadays have to deal concerning their classroom-arrangements: new teaching methods and integrating computers. Many teachers are afraid that when realising both trends, curricular prescriptions can become even more difficult to achieve. Changes in the classroom-arrangements and…

The purpose of this project is to help teachers of mathematics use the computer to aid the teaching and learning of many mathematical concepts in a meaningful way. To this end, commercially available software packages are described which are versatile, cost effective, and easy to use. A review and several lessons, each including homework…

Used computer simulations to examine effectiveness of different criteria for measuring infant visual habituation. Found that a criterion based on fitting a second-order polynomial regression function to looking-time data produced more accurate estimation of looking times and higher power for detecting novelty effects than did the traditional…

Admittedly, the Fundamental Theorem of Calculus-TFA holds an important role in the Complex Analysis-CA, as well as in other mathematical branches. In this article, we bring a discussion about the TFA, the Rouché's theorem and the winding number with the intention to analyze the roots of a polynomial equation. We propose also a description for a…

The second part of Course III includes a study of probability, polynomial, rational and circular functions, and informal space geometry. The chapter on probability presents such topics as probability measure, outcome sets and events, and overview of topics studied in Courses I and II. Chapters on functions include polynomial algebra concepts and…

This is the instructor's guide to a text designed for the contemporary business student who frequently questions the need for studying mathematics. The text material is presented in a "building-block" fashion, with skills learned in earlier chapters organized to provide a smooth transition into more difficult topics. This guide consists…

The primary aim of this guide is to aid teachers in planning and preparing a senior high school mathematics course for students preparing for college work. It is divided into separate one-semester courses of seven chapters each. The first-semester course consists of a traditional approach to the introduction of trigonometry and trigonometric…

This study aims to bridge a gap between Vygotsky's seminal framework on the importance of make-believe play and adult scaffolding in children's cognitive development (e.g. executive function [EFs]) and research in cognitive neuroscience. Kindergarten children (N = 160) and teachers (N = 12) took part in the study. EFs skills and make-believe play…
