Considered is the open-ended question of the various means of marking an n-inch ruler so that the distance of any integral number of inches from 1 to n can be ascertained with a single measurement. The relationship between a sparsely marked ruler, which is one gracefully marked with the fewest number of marks, and specific discrete graphs is…

Clapping music for two performers provides the basis for a series of mathematical problems in combinatorics and group theory. A discussion provides insight about how to avoid overlooking global extrema in constrained max-min problems when solving systems of algebraic equations. (JJK)

A series of four activities are presented to enhance students' abilities to appreciate and use trigonometry as a tool in problem solving. Activities cover problems applying the law of sines, the law of cosines, and matching equivalent trigonometric expressions. A teacher's guide, worksheets, and answers are provided. (MDH)

The incidence of school violence has increased in recent years. In response to the escalation, Deborah Prothrow-Stith developed a violence prevention curriculum to be taught in high schools; it has also been used in middle schools. The first section of this journal issue's report, "Confronting an Epidemic" offers details of Prothrow-Stith's…

Twelve junior and senior high schools in California and ten in New York City are working to mitigate violence and vandalism in their schools and reduce high droupout and absentee rates by addressing a problem central to these issues--student alienation. Through the Open Road Student Involvement Project, natural student leaders form a volunteer…

Following a brief historical review of the mechanism of mathematical modeling, examples are included that associate a mathematical model with given data (changes in sea level) and that model a real-life situation (process of parallel parking). Also provided is the rationale for the curricular implementation of mathematical modeling. (JJK)

Presented are student activities that involve two standard problems from geometry and calculus--the volume of a box and the bank shot on a pool table. Problem solving is emphasized as a method of inquiry and application with descriptions of the results using graphical, numerical, and physical models. (JJK)

This publication is a compilation of abstracts and critical comments for 12 published investigations in mathematics education. Information for each study includes: purpose; rationale; research design and procedures; findings; and interpretations. For each study also, abstractor's comments provide a brief critique. The 12 studies are: (1)…

This publication is an abstracted compilation of 11 investigations. The information includes purpose, rationale, research design and procedures, findings, interpretations, abstractor's comments, previous research, procedure and statistical methods, and further research. Contained within are: (1) "Gender-Based Differential Item Performance in…

This document contains 11 papers: "Integrated English/Keyboarding Instruction: Potential for Contextual Learning" (Baker, Anderson-Yates); "Incorporating Industry-Based Skill Standards into High School Secretarial and Administrative/Information Services Programs" (Bunn, Schmidt, Stewart); "The Effect of Two Different Interfaces for Database…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The ten titles deal with the following topics: (1) the effect of dramatic improvisation on the attitudes of high school teachers toward their students; (2) the effects of training teachers in interpersonal cognitive problem solving…

The two articles in this publication should be useful to those developing the kinds of materials, experiences, and thinking that elementary school industrial arts offers children. Floyd Robinson, in the first article, sketches some ideas along with the general scheme that the Ontario (Canada) Institute for Studies in Education's Elementary School…

This annual serial issue contains six papers dealing with business education and training. Three approaches to teaching problem solving are detailed in "Teaching Problem Solving for Employment Preparation" (Judith J. Lambrecht). A study to identify the technologies used to manage information in business and industry is reported in…

This annual journal contains nine articles dealing with business education in Louisiana and elsewhere. The articles "Word Processing Competencies: Which Ones Are Really Necessary?" (Patricia Lynn Anderson, Mary Alice Griffin) and "English Basics Were Developed in Shorthand--Why Not in Keyboarding?" (Clora Mae Baker, Marcia A.…
