The various roles and uses of mathematics in developing global awareness in students are considered. Mathematics as a unifier of human experience and problem solving with a global emphasis are discussed with many illustrative examples. (MNS)

Suggests that problems designed for classroom use should include such factors as ways to introduce the problem, the skills to be developed, the mathematical prerequisites for the problem, key questions, extensions, and solutions. An example is provided which illustrates these and other points. (JN)

Investigated whether attitudes toward school mathematics on mathematical achievement differed between low and high intelligence eighth-grade students in three Japanese schools (N=808). Results indicate that the attitude of low intelligence students is more important and it affects more in magnitude than that of high intelligence students. (JN)

A computer program is presented which simulates the classical probability machine, using Applesoft II high-resolution graphics. Many variables are left to the user's choosing. Suggestions for using the machine, understanding the problem, the mathematical model, and further program documentation are given. (MNS)

The geometry of perspective drawing is developed and discussed. (SD)

The author advocates the use of questions whose relevance to the topic being studied as not immediately apparent, as a method of broadening students' facility and interest in their mathematics classes. (SD)

Four features of teaching aids which endure are identified and discussed, and the nature of the electronic calculator as a teaching aid is analyzed. (DT)

This article provides checklists designed to help educators select an appropriate minicalculator for their individual or groups situation. (DT)

Methods of finding algebraic expressions to fit number patterns are explored. (DT)

The history of mathematics curriculum revision since 1900 is described, the present day school mathematics situation is analyzed, and suggestions for a two-track mathematics program are given. (DT)

This bibliography lists articles concerned with mathematics beyond that usually taught in the junior high school and also includes bibliographical references to mathematicians, journals, and societies. Twenty-one different categories were used in organizing the entries. (DT)

The impact of the NACOME report for curriculum design is examined. The logical approach vs. the intuitive approach for teaching mathematics is discussed and recommendations for further curriculum reform are made. (DT)

Details are given concerning instructional materials on basic geometry concepts for secondary school students. The contents of the learning package and format of the material are described, samples from accompanying workbooks are presented and discussed, and enrichment activities are suggested. (DT)

Thirty-five students from all ability levels in the first and second year of secondary school were interviewed to determine their understanding of appropriate application of number operations. Results of the interviews are classified into five different levels of understanding. (DT)

A logic puzzle is presented. (DT)
