This experiment designed for beginning physics students, is related to postal regulations restricting the size of envelopes. A graph is constructed that allows for testing the mailability of envelopes. (MP)

Graphical solutions are illustrated for several algebra problems including finding roots of a quadratic equation, solving mixture and motion word problems, factoring the difference of two squares, and constructing the square root of a positive number. (MN)

Explores whether the differences in use of terminology were related to respective fields or to idiosyncratic characteristics of experience and education. Reports differences among college teachers, high school teachers, and college students from a 16-item survey on algebraic and graphing terminology used in mathematics and science. (YP)

The Triple Representation Model of problem solving is presented. The use of microcomputers in this problem-solving environment is discussed, and examples are provided. The integration of this method into the mathematics curriculum is described. (CW)
