NCTM = "National Council of Teachers of Mathematics" (just learned that on AltaVista).
FWIW, the used-electronics reseller from whom I bought a 34C and 41CV has told me how some unnamed high school math teacher's methods. (S)he instructs about graphing by listing the sequence of keystrokes to obtain specified plots, specific to a given type of graphing calculator (probably a TI). The propietor wonders aloud what is being taught in today's schools. Is this an isolated example, or standard practice?
