The students’ approaches to calculation on their
calculators partly reflected Artigue’s (1996) findings on
efficient use of full computer algebra systems. Quickness
and ease were pursued (a) in numerical calculation, (b)
through selection of algebraic solutions in preference to
graphical solutions and vice versa, and (c) involved co-
ordination of numerical, graphical and algebraic work. The
social means to quickness, in the main, comprised debate,
direction by the teacher, and use of a view screen with
students’ calculators attached.
