Problem solving is the thought processes involved in solving a problem. It is both a means of developing students' knowledge of mathematics and a critical outcome of a good mathematics education. A mathematical problem, as distinct from an exercise, requires the solver to search for a method for solving the problem rather than following a set procedure. Mathematical problem solving, therefore, requires an understanding of relevant concepts, procedures, and strategies. To become good problem solv

Whole Building Design Guide
The National Institute of Building Sciences is developing the Whole Building Design Guide (WBDG). While not yet complete, there is already a substantial knowledge base for building professionals to draw upon. The purpose of WBDG is to help designers "improve the performance and quality of their buildings by following the guidance and recommendations provided within the categories of this web site." There are sections for specific building types and design objectives. Eventually, WBDG will have a
Appetizers and Lessons for Mathematics and Reason: Linear Equations
This section of the website, Appetizers and Lessons for Mathematics and Reason, written by Alan Selby, PD. (see also Scout Report for Math, Engineering, and Technology, May 24, 2002) offers lesson ideas for teaching linear equations in high school or college. The approach uses stick diagrams to solve linear equations because they "provide a concrete or visual context for many of the rules or patterns for solving equations, a context that may develop equation solving skills and confidence."
