Racial profiling--the use of race, ethnicity, or national origin by law enforcement officials to make judgments of criminal suspicion--is assessed in terms of its effect on targeted populations and on law enforcement efficiency. A mathematical simulation, comparing multiple profiling and non-profiling scenarios, is employed. This analysis…

Many counting problems can be modeled as "colorings" and solved by considering symmetries and Polya's cycle index polynomial. This paper presents a "Maple 7" program link http://users.tamuk.edu/kfdrc00/ that, given Polya's cycle index polynomial, determines all possible associated colorings and their partitioning into equivalence classes. These…

This classroom scholarship report is based on the teaching experience using Davydov's mathematics curriculum, which was developed in the former Soviet Union. While "from arithmetic to algebra" is the normally accepted instructional sequence in school mathematics, Davydov's curriculum is laid out "from algebra to arithmetic," focusing on algebraic…

This Australian document is a guide to teaching mathematics as it relates to specific work situations. After a brief introduction, chapter 1 looks at problem solving, advises teachers to lower the reading level and thus raise the understandability of written math problems, and describes a four-step problem-solving process. Chapter 2 outlines a…

This paper presents a method for higher education faculty and staff to assess pension plan objectives by determining a retirement income replacement ratio to maintain the salary-based preretirement standard of living. The paper describes the RETIRE Project which researches income replacement using the federal government's annual "Consumer…

Three local norm methods for deriving Elementary Secondary Education Act Title I normal curve equivalent (NCE) gains are compared to each other and to the usual Model A1 which uses national norms. The 1977-78 Title I evaluation data for Chicago students ages 9-13 were used to estimate gains. Reading and total math scores from the 1971 Iowa Tests…

In this report, revisions made by the New Jersey State Board of Education to its administrative code in order to implement provisions of the law providing an additional cost factor for the state compensatory education fund are described. Methods utilized by Federal and State governments for targeting resources are discussed. including…

This project involves devising and evaluating a sales tax schedule to meet the specific revenue needs of a hypothetical state in the United States. Conducting this unit involves many mathematical skills in a learning environment familiar to the student. The essential parts of the project consist of student preparation of a tax schedule and class…

This report contains recommendations on chemical nomenclature, guidance on symbols, and terminology and units for physiochemical quantities. This report, intended to provide guidance to science teachers, consists of eleven sections: (1) general introduction; (2) introduction to symbols, terminology, and units for physiochemical quantities; (3)…

Three different computational procedures for equating two forms of a test were applied to a pair of mathematics tests to compare the results of the three procedures. The tests that were being equated were two forms of the SRA Mastery Mathematics Tests. The common, linking test used for equating was the Comprehensive Tests of Basic Skills, Form S,…

The ratings of 43 third-year medical students were used to investigate a method of computing the reliability of ratings. The students were evaluated on a four-point rating scale along seven dimensions of clinical ability: diagnostic ability; motivation; sense of responsibility; oral-verbal ability; effectiveness with patients; ability to take a…
