How are teachers informed of upcoming workshops?
We have slowly been putting together a list of high school calculus teachers in the Tucson area and surrounding communities. This is easier said than done. We started with the Tucson phone book, phoning schools asking whether anyone there teaches calculus. More names were added by word of mouth. Then we obtained lists of public schools from various school districts and again phoned each school. Some of the workshops are directed also at precalculus and computer science classes; in these cases we rely on the calculus teachers on our list to pass on the letters to the appropriate teachers.
