This report describes a program for improving attitudes towards mathematics and problem solving in order to improve performance in these areas. The targeted population consists of two high school geometry classes. The school is located in a western suburb of a major mid-western city. The problems of negative attitudes towards mathematics and…

This profile is designed to be a recording sheet for monitoring an individual student's progress throughout the school year. Seventh grade assessment materials and the Strategies for Instruction in Mathematics suggest tasks and questions that can be used for on-going and summative assessment. Directions for use and descriptions of the four levels…

Multiple embodiment is explained and discussed, with activities described that might be used to develop concepts in geometry and in arithmetic. A series of questions is raised about the choice, use, and organization of embodiments; suggestions for action research are made. (DT)

The philosophy and contents of a single one-year course preparatory to college algebra and trigonometry are presented. (MM)

A Snip of the Scissors" describes the geometry involved in making stars by paper folding, and Checking the Calculated Average Through Subtraction" suggests practice in operations with negative numbers. (MM)

An approach is presented that is based on modifying the standard axiomatic system found in high school geometry books. Such changes start with the introduction of a side-angle-side (SAS) postulate for similar triangles. It is shown how the new system can prove existence and uniqueness of parallel lines. (MP)

A Norman window consists of a semi-circular section mounted surmounting a rectangular section. Modifications to a simple problem are presented that assume parts of the window are made with stained glass. The goal is to maximize the level of light transmission with a fixed perimeter. (MP)
