Using the overhead projector, or overlays on an original pattern, a variety of tessellations can be generated. Several illustrations are included. (SD)

Theory and research concerning the development of spatial concepts by young children are discussed. Results of Martin and Kidder are compared with those of Piaget. (SD)

The validity of the formula for the sum of the measures of the interior angles of polygon is explored using non-convex polygons. (SD)

The author describes several physical problems whose solutions involve a helix. He argues that students remember "offbeat" approaches to important mathematical concepts. (SD)

The author reviews the history of the Fibonacci sequence and its relation to Pascal's triangle. (SD)

Observing the relationship of general relativity and the geometry of space-time, the author questions whether the rest of physics has geometrical explanations. As a partial answer he discusses current research on subatomic particles employing geometric transformations, and cites the existence of geometrical definitions of physical quantities such…

A mathematics contest, held to acquaint able high-school students with their area community college, is described. (SD)

This module was designed to allow students to build or increase their level of understanding of geometry. It helps students develop those skills necessary to successfully understand and use basic geometry skills that are necessary for many vocational jobs and that act as a basis for additional understanding. The seven units include: (1)…

An Intelligent Tutoring System (ITS) consists of an expert problem-solving program in a subject domain, a tutoring model capable of remediation or primary instruction, and an assessment model that monitors student understanding. The Geometry Proof Tutor (GPT) is an ITS which was developed at Carnegie Mellon University and field tested in the…

It has been suggested that males perform better than females in mathematics after ninth grade because more males than females enroll in advanced mathematics courses in high school. However, factors other than enrollment may be involved. Therefore, this study investigated whether the performance of males (B=500) and females (N=500) was different in…

Designed to accompany a series of videotapes, this textbook provides information, examples, problems, and solutions relating to mathematics and its applications in technical fields. Chapter I deals with basic arithmetic, providing information on fractions, decimals, ratios, proportions, percentages, and order of operations. Chapter II focuses on…

This booklet contains 11 modules (290 multiple-choice items) designed for use in the first course of a three-course calculus sequence using the textbook "Calculus with Analytic Geometry" (Dennis G. Zill). In each module, relevant sections of the textbook are identified for users. It can, however, be used in conjunction with any calculus textbook.…

The 1985 Indiana Mathematics Contest included tests in Algebra (First Course), Geometry, Algebra (Second Course), and Comprehensive. Test-writing responsibilities were delegated to mathematics and mathematics education faculties at four state universities, with the mathematical content based on course objectives in the state guidelines. Fourteen…

Because of the extensiveness of the course outline for Math 201 (Manitoba Department of Education), schools would have had to purchase several different textbooks to cover the material adequately. Therefore, a set of materials to supplement the guide was developed. The exercises, projects, and reviews contained in this package are keyed to the 201…
