The Topic Group 18 "Roles of calculators in the classroom" centered its work on graphing calculators and new hand-held computers and their role in Mathematics Education. Its target population was secondary teachers with little experience with calculators.This group met on two occasions, each of 90 minutes duration. Between 100-150 attended each session.The purposes of this Topic Group were: To inform, develop and support reflection and discussion concerning the roles that calculators have played and can play in the teaching and learning of Secondary Mathematics. To show both why and how teachers would want their students to use hand-held computer technology. To present the "state of the art" on calculators and hand-held computers and their role in Mathematics Education.Each of the two sessions were divided into three activities: two plenary presentations (20 minutes each) in each session; short talks in which specific projects and experiences were presented; the last 20 minutes of each session were used for discussion and questions.
