An activity is presented in which students use eight-place pocket calculators to demonstrate their knowledge of correct order of operations for mathematical expressions. After performing an indicated computation and getting a result, the student inverts the calculator to obtain a word or abbreviation to be entered in a crossword puzzle. (MN)

The authors derive distance formulas in two-and-three-dimensional coordinate geometry utilizing the concept of similar triangles and the Pythagorean theorem. (MN)

An interview with Geoffrey Matthews touches upon his involvement with Contemporary School Mathematics Series, Concepts in Secondary Mathematics and Science Project, Early Mathematical Experiences, and the Mathematical Association. (MN)

It is shown that, by taking as the basis unit vectors along the sides of an equilateral triangle, certain isometric transformations can easily be determined in matrix form. (MN)

The author demonstrates that many secondary school students have poor concepts of area and point of view; she argues for diagnostic teaching with respect to formal geometry. Examples of diagnostic activities for determining the development of concepts of space are given. (MN)

The author pinpoints those aspects of education where calculators seem sure to have an impact and quotes from several reports that outline some of the short-term and long-term things mathematics educators may need to do to bring about an orderly and fruitful adjustment to calculators. (MN)

An innovative feature added to one high school curriculum is described whereby mathematics students write programs for problems that relate to topics studied in a given course. Sample programs illustrating the type of work being done are given. (MN)

The author argues that the emphasis on logic and set theory in the school mathematics program is unnecessary and possibly harmful. He discusses briefly the relationships between semantics and logic. (SD)

The rationale for using a camping situation in which children learn and do mathematics is discussed. (DT)

Generating functions for the columns in Pascal's triangle are constructed through algebraic and geometric interpretations. (JT)

Three activities which provide experience in writing and solving original story problems are described. (JT)

The history of mathematics education in New South Wales State High Schools in the late nineteenth century is outlined including the influence of the Junior and Senior Public Examinations on curriculum development. (MN)

Provides a computer program in BASIC language by which a least squares approximation of a straight line may be determined. (CP)

This paper focuses on Islamic Art with its characteristic complex geometric patterns as an instance of mathematical constructs being used as a solution for artistic problems. (MN)

Trained raters analyzed the educational and psychometric quality of standardized mathematics tests for high school students in the United States. Results showed many tests to be weak in common types of validity and reliability. General mathematics tests had, as a rule, higher ratings than applied mathematics, algebra, or geometry tests.
