Presents the assessment and grading practices of 19 mathematics classes in five high schools in three states. In each class the most frequently used assessment tools were tests and quizzes, with these determining approximately 77% of students' grades. In 12 classes other forms of assessment such as written projects or interviews were also used.…

This study of 461 Colorado students (ages 7-18) with deafness or partial hearing investigated the students' psychoeducational development by age and hearing loss, including syntactic comprehension and production, reading comprehension, social maturity, speech intelligibility, and math calculation skills. Traditional standardized measures of…

A study investigated the mathematical problem-solving abilities of 18 fourth-graders with mathematics disabilities (MD) with and without comorbid reading disabilities (RD). Results demonstrated large deficits for both groups. However, the differences between students with and without RD were mediated by the level of problem solving and by…

A method for helping students to find formulas involving symmetry under various conditions is explained. Necklace symmetries, orbit counting, tetrahedra and cubes, relationship patterns, and finding patterns are discussed. (CW)

Activities which may be used to investigate a variety of woven patterns are presented. Pattern predicting and analysis of different patterns are discussed. A Basic computer program for the weaving code is given. (CW)

Algorithmic and investigative approaches to mathematics are compared and discussed. Their mutually contradictory spirit is explored. Examples of the application of each method to a mathematics problem are presented. (CW)

Described is an activity where base-10 blocks are used to develop students' skills in reading, writing, and visualizing large numbers. An activity sheet that helps students with decimal points is included. (KR)

Discusses the use of world problems in mathematics curriculum. Provides a topic on (1) life expectancy and the percentage of the population with access to safe drinking water and (2) the global arms race. (YP)

Discusses what a good problem is. Describes the eight problem categories and the four dimensions for evaluating problem-solving performance. (YP)

Discussed are the major historical developments of geometry. Euclid, Descartes, Klein's Erlanger Program, Gaus and Riemann, globalization, topology, Elie Cartan, and an application to molecular biology are included as topics. (KR)

Presented is an activity in which students apply familiar concepts of geometry to novel settings. Using square dot paper and isometric dot paper, students trace routes and determine the geometry of each circle. (KR)

Discussed are several activities suitable for students from middle school through high school designed to furnish concrete experiences with the concepts of rate of change and slope and approximating areas, the central themes of differential and integral calculus. The implementation of national curriculum standards is stressed. (CW)

Discusses the use of calculators to calculate multiple operations. Describes calculating procedures and provides four different types of examples. (YP)

Describes the results of three years of field-work and the prospects for change in algebra teaching as a consequence of using computers and calculators. Summarizes the structure of text materials, classroom organization, and students' responsibilities. (YP)

Discussed are some objections to using calculators in mathematics instruction and testing. Indicates that many commercially available tests do not permit the use of a calculator. Several steps to facilitate the use of calculators are suggested. (YP)
