This document is a collection of reports presented at a programable calculator symposium held in Seattle, Washington, in April, 1980, as part of the annual meeting of the National Council of Teachers of Mathematics (NCTM). The session was designed to review whether the programable calculator has a place in the school mathematics program, in light of the current availability of the microcomputer. The presentations at the symposium supported the view that such calculators do have a role to play in the curriculum, and the collected papers of the contributors provide ample evidence of the many ways programable calculators can be used. In addition to the presented papers, two other contributions solicited by the editor to enhance the usefulness of this work to educators are included. (MP)
