Investigating properties and characteristics of unary operations is shown to be facilitated by using calculators. Several avenues for instructional exploration are suggested and examples given. These include questions relating to relations, inverses, commutativity, distributivity, and iterations. A discussion of the calculator algorithm for…

Some of the determinants of the decision to take or not to take mathematics are explored. The focus is on sex and grade differences in responses to questions about mathematics. The results show that fifth- and sixth-grade girls tended to have higher expectancies for success as well as higher ratings of their ability in mathematics than the boys…

This is part three of a three-part manual for teachers using SMSG high school text materials. The overall purpose for each of the chapters is described and the mathematical development detailed. Background information for key concepts and answers for all exercises in each chapter are provided. Chapter topics include: (1) vectors and curves; (2)…

Three evaluation forms are contained in this publication by the Winston-Salem/Forsyth Metric Education Project to be used in conjunction with their materials. They are: (1) Field-Test Materials Evaluation Form; (2) Student Materials Evaluation Form; and (3) Composite Materials Evaluation Form. The questions in these forms are phrased so they can…

This curriculum guide covers Course III of a three-year sequence for high school mathematics in New York which was intended to provide an alternative to the regular Regents sequence of ninth-, tenth-, and eleventh-grade mathematics. A listing of scope and content is provided along with suggested time allotments. Topics covered are: complex…

This is part two of a three-part School Mathematics Study Group (SMSG) textbook. This part includes the index and chapters 6 through 10: (6) Curve Sketching and Locus Problems, (7) Conic Sections, (8) The Line and the Plane in 3-Space, (9) Quadric Surfaces, and (10) Geometric Transformations. (MK)

This is the teacher's commentary for part one of a three-part SMSG algebra text for high school students. The principal objective of the text is to help the student develop an understanding and appreciation of some of the algebraic structure as a basis for the techniques of algebra. Chapter topics include congruence; numbers and variables;…

THIS IS VOLUME 1 OF A THREE-VOLUME EXPERIMENTAL EDITION CONTAINING A SEQUENCE OF ENRICHED MATERIALS FOR SEVENTH-GRADE MATHEMATICS. THESE MATERIALS ARE DESIGNED FOR A PROGRAM OF INDIVIDUALIZED INSTRUCTION FOR THE ACCELERATED STUDENT OR FOR CLASSROOM PRESENTATION BY THE TEACHER. THE PRESENTATION OF THE MATERIAL IS IN SUCH A MANNER AS TO REFLECT…

This paper is presented in two sections. The first considers survey research, both in general and educational contexts, and outlines the potential utility of combining survey methods and observational fieldwork in studying different aspects of the same phenomenon. The second provides background for, and a description of, the survey phase of IRT's…

This is one in a series of SMSG supplementary and enrichment pamphlets for high school students. This series is designed to make material for the study of topics of special interest to students readily accessible in classroom quantity. Topics covered include: (1) graphs; (2) constant, linear, and absolute-value functions; (3) composition and…
